ReST API Java Wrapper Extension Point

One of the libraries provided by the SDK for out-of-process extensions is the Java ReST API wrapper library. It enables you to work with the Alfresco ReST API from a Java client with standard Java classes. There is no need to parse JSON or create HTTP requests.

To set up a project with the Java ReST API library follow these instructions.

Common parameters

There are some common parameters in the different API calls. They are documented here instead of repeating the docs for them under multiple sections:

Parameter Description Usage
include Use this parameter to return additional information about the node. The following optional fields can be requested: allowableOperations, aspectNames, association, isLink, isFavorite, isLocked, path, properties, permissions. List<String> include = new ArrayList<>(); include.add("permissions");
fields You can use this parameter to restrict the fields returned within a response if, for example, you want to save on overall bandwidth. The list applies to a returned individual entity or entries within a collection. If the API method also supports the include parameter, then the fields specified in include parameter are returned in addition to those specified in the fields parameter. List<String> fields = new ArrayList<>(); fields.add("content,createdAt");
Note that all fields have to be added as one item comma separated.
where Optionally filter the node list. Here are some examples:
(isFolder=true)
(isFile=true)
(nodeType='my:specialNodeType')
(nodeType='my:specialNodeType INCLUDESUBTYPES')
(id BETWEEN ('1', '79'))
includeSource Also include source in addition to entries with folder information on the parent node – either the specified parent nodeId, or as resolved by relativePath Boolean includeSource = false;
orderBy A string to control the order of the entities returned in a list. The default sort order for the returned list is for folders to be sorted before files, and by ascending name. You can override the default using orderBy to specify one or more fields to sort by. The default order is always ascending, but you can use an optional ASC or DESC modifier to specify an ascending or descending sort order. For example, specifying orderBy=name DESC returns a mixed folder/file list in descending name order. You can use any of the following fields to order the results: isFolder, name, mimeType, nodeType, sizeInBytes, modifiedAt, createdAt, modifiedByUser, createdByUser List<String> orderBy = new ArrayList<>(); orderBy.add("title");
skipCount The number of entities that exist in the collection before those included in this list, useful when implementing paging scenarios. If not supplied then the default value is 0. Integer skipCount = 0;
maxItems The maximum number of items to return in the list, useful when implementing paging scenarios. If not supplied then the default value is 100. Integer maxItems = 100;
autoRename If true, then a name clash will cause an attempt to auto rename by finding a unique name using an integer suffix. Boolean autoRename = true;
versioningEnabled Should versioning of files be enabled at all? Boolean versioningEnabled = true;
majorVersion If true, then it will be a major version, such as 1.0, 2.0 etc. If false, then the version change will be 1.1, 1.2, which is a minor version change. Boolean majorVersion = true;
updateComment Add a version comment which will appear in version history. Setting this parameter also enables versioning of this node, if it is not already versioned. String updateComment = "A comment";
updatedName Optional new name of the node, sets cm:name. This should include the file extension. The name must not contain spaces or the following special characters: * " < > \ / ? : |. The character . must not be used at the end of the name. String updatedName = null; if not updating or set to new name.

=== Managing Folders and Files ===

The following sections walk through how to use the Java ReST API wrapper services when managing folders and files.

List contents of a folder

To list contents of a folder in the repository use the listNodeChildren method of the NodesApi, which is one of the main APIs used when you want to manipulate folders and files.

Filter contents of a folder

To filter listed contents of a folder in the repository use the listNodeChildren method of the NodesApi and set the where clause parameter.

        }

        return result;

}

Get folder/file metadata

To get metadata for a node, such as a file or folder, in the repository use the getNode method of the NodesApi, which is one of the main APIs used when you want to manipulate folders and files.

import java.util.List;

@Component
public class GetNodeMetadataCmd {
    static final Logger LOGGER = LoggerFactory.getLogger(GetNodeMetadataCmd.class);

    @Autowired

        Node node = getNode("-root-", null);
        Node node2 = getNode("-root-", "/Data Dictionary");
    }

    /**

     *
     * @param nodeId             the id of the node that we want to fetch metadata for. If relativeFolderPath is specified, then metadata for this node will be returned. Besides node ID the aliases -my-, -root- and -shared- are also supported.
     * @param relativeFolderPath A path relative to the nodeId, if this is not null, then metadata is returned on the node resolved by this path
     * @return Node object if exist, or null if does not exist
     */
    private Node getNode(String nodeId,
                         String relativeFolderPath) {
        List<String> include = null;
        List<String> fields = null;

        NodeEntry result = nodesApi.getNode(nodeId, include, relativeFolderPath, fields).getBody();
        LOGGER.info("Got node {}", result.getEntry());
        return result.getEntry();
    }
}

Executing this code would give the following result:

Upload a file

To upload a file to the repository use first the NodesApi.createNode method, which will create the metadata for the file, and then the NodesApi.updateNodeContent method that will set the content for the file.

At the moment it’s necessary to make two calls to upload a file, but enhancements are being developed in a new version of SDK 5 to provide a one method approach as this is supported in the ReST API.

Upload a file with custom type

Uploading a file with a custom type to the Repository means creating a node with a type other than cm:content. See upload a file for info on how to upload a file with the out-of-the-box content type cm:content set. There’s actually not much difference to how you upload a file with a custom type. Let’s say we have a content model type acme:document and an aspect acme:securityClassified and these are defined as follows:

<type name="acme:document">
   <title>Sample Document Type</title>
   <parent>cm:content</parent>
   <properties>
       <property name="acme:documentId">
           <title>Document Identification Number</title>
           <type>d:text</type>
       </property>
   </properties>
   <mandatory-aspects>
       <aspect>acme:securityClassified</aspect>
   </mandatory-aspects>
</type>

<aspect name="acme:securityClassified">
    <title>ACME Security Classified</title>
    <description>Content has been security classified</description>
    <properties>
        <property name="acme:securityClassification">
            <type>d:text</type>
            <index enabled="true">
                <atomic>true</atomic>
                <stored>false</stored>
                <tokenised>false</tokenised>
            </index>
            <constraints>
                <constraint ref="acme:securityClassificationOptions"/>
            </constraints>
        </property>
    </properties>
</aspect>

We got two custom properties acme:documentId and acme:securityClassification. For more information on how to implement and deploy this custom content model see this documentation.

Now, to upload a file and set this custom type and aspect we use the same code as for upload a file with minor updates to the contentType variable and the createFileMetadata method:

In this example we pass in two file node identifiers that will be requested in the zip download. The zip download file will be stored in current directory under the name mydownload.zip. Note that right after we have initialized the creation of the zip download there are no files added to the zip (filesAdded: 0), we have to wait for the zip download to be created on the server side. Then we can download with the usual getNodeContent method.

List file renditions

To list content renditions for a file use the RenditionsApi.listRenditions method.

        LOGGER.info("Updated node {}", result.getEntry());

        return result.getEntry();
    }
}

With the updateNode call we can update properties, aspects, and permissions for a node. Note that when updating aspects you need to include the complete list of aspects that should be set on the node as this call overwrites. You can fetch existing aspects with the getNodeMetadata call. If you are adding an aspect that has properties, then you can just add the properties and the aspect will be added automatically for you.

We can see the updated name and properties in the returned node object.

Add aspects to a folder or file

To add aspects to a node, use the NodesApi.updateNode method. The way you do this is described in the update metadata for a node section. Note that you only need to add aspects to a node when they are so called “marker” aspects without properties.

More info about this ReST API endpoint

Remove aspects from a folder or file

To remove aspects from a node, use the NodesApi.updateNode method. The way you do this is described in the update metadata for a node section.

Removing an aspect from a node is similar to how you add a “marker” aspect. You first get the list of aspects currently applied to the node. Then you remove the aspect from the list. And finally you use an update node call with the updated aspect list.

Get and Set permissions for a folder or file

To manage permissions for a node, use the NodesApi.updateNode method.

Note that you have to first get the currently set permissions before you set the new ones. This is because the update call will overwrite permissions already set. So we use the getNodeMetadata call to get already set node permissions.

We can see that before the permission update there were no locally set permissions for the node, only inherited. After the update we see also the locallySet returned with the newly set permissions. Note that for the permission information to be returned with each call we have to add permissions to the include parameter.

Working with relationships between folders/files

To manage relationships (referred to as associations) between nodes use the NodesApi and the following methods:

Method Description
listNodeChildren List primary parent-child associations, see list folder content
createSecondaryChildAssociation Create secondary parent-child association
deleteSecondaryChildAssociation Delete secondary parent-child association
listSecondaryChildren List secondary parent-child associations
createAssociation Create peer-2-peer association
deleteAssociation Delete peer-2-peer association(s)
listSourceAssociations List source peer-2-peer associations
listTargetAssociations List target peer-2-peer associations

More info about this ReST API endpoint

For a description of the common parameters, such as include, see this section.

Assuming we have deployed the FDK content model with secondary parent-child and peer-2-peer association types, then the following code examples shows how to create those types of associations (it also shows how to upload files, create folder, create node of different type):

Note. this code assumes the following two files exists in current directory: somepicture.png and sometext.txt.

Note the extra properties at the end that tells you when the node was soft deleted and by who (i.e. archivedAt and archivedByUser). Also, by setting the include parameter to path we get information about where the node was located before it was deleted (i.e. path.name)

Restore deleted folders and files (Trashcan)

To list deleted nodes, use the restoreDeletedNode method of the TrashcanApi.

import org.springframework.stereotype.Component;

import java.io.IOException;
import java.util.List;

@Component
public class RestoreDeletedNodeCmd {
    static final Logger LOGGER = LoggerFactory.getLogger(RestoreDeletedNodeCmd.class);

    @Autowired
    TrashcanApi trashcanApi;

    public void execute(String nodeId, String restoreFolderId) throws IOException {
        List<String> fields = null;

        // POST body need to ne supplied with target folder ID
        DeletedNodeBodyRestore deletedNodeBodyRestore = new DeletedNodeBodyRestore();
        deletedNodeBodyRestore.setTargetParentId(restoreFolderId);
        deletedNodeBodyRestore.setAssocType("cm:contains");

        LOGGER.info("Restored node: {}", restoredNode.getEntry());
    }
}

Executing this code would restore a node with passed in ID. The location folder ID is also passed in:

=== Managing Sites ===

The following sections walk through how to use the Java ReST API wrapper services when managing Alfresco Share sites.

Create a site

To create an Alfresco Share site in the repository use the createSite method of the SitesApi, which is the main API used to create and manage sites.

More info about this ReST API endpoint

For a description of the common parameters, such as fields, see this section.

import org.alfresco.core.handler.SitesApi;
import org.alfresco.core.model.Site;
import org.alfresco.core.model.SiteBodyCreate;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

import java.io.IOException;
import java.util.List;

@Component
public class CreateSite {
    static final Logger LOGGER = LoggerFactory.getLogger(CreateSite.class);

    private List<String> fields = null;

    // Flag to indicate whether the Share-specific (surf) configuration files for the site should not be created
    // Default = false
    Boolean skipConfiguration = null;
    // Flag to indicate whether the site should not be added to the user's site favorites
    // Default = false
    Boolean skipAddToFavorites = null;

    @Autowired
    SitesApi sitesApi;

    public void execute(String siteId) throws IOException {
        SiteBodyCreate siteBodyCreate = new SiteBodyCreate();
        siteBodyCreate.setId(siteId);
        siteBodyCreate.setTitle("title-" + siteId);
        siteBodyCreate.setDescription("description-" + siteId);
        siteBodyCreate.setVisibility(SiteBodyCreate.VisibilityEnum.PUBLIC);

        Site site = sitesApi.createSite(siteBodyCreate, skipConfiguration, skipAddToFavorites, fields).getBody().getEntry();

        LOGGER.info("Created site: {}", site);
    }
}

List site containers

For more information about how to list site containers, such as Document Library, for a site see add content to site.

Add content to a site

Adding content to a site uses the same API calls as are used to create folders and upload files elsewhere in the Repository. See create folder and upload file for more information.

More info about this ReST API endpoint

For a description of the common parameters, such as fields, see this section.

The tricky bit is to figure out how to add content to the so called “Document Library” of a site. We can figure out the Node ID for the Document Library by using the listSiteContainers method of the SitesApi:

import org.alfresco.core.handler.NodesApi;
import org.alfresco.core.handler.SitesApi;
import org.alfresco.core.model.*;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

import java.io.IOException;
import java.util.List;

@Component
public class AddSiteContentCmd {
    static final Logger LOGGER = LoggerFactory.getLogger(AddSiteContentCmd.class);

    Integer skipCount = 0;
    Integer maxItems = 100;
    private List<String> fields = null;
    private List<String> include = null;
    private Boolean autoRename = true;
    private Boolean majorVersion = true;
    private Boolean versioningEnabled = true;

    @Autowired
    SitesApi sitesApi;

    @Autowired
    NodesApi nodesApi;

    public void execute(String siteId) throws IOException {
        // First get the Node ID for the Document Library
        String docLibNodeId = null;
        SiteContainerPaging siteContainerPaging = sitesApi.listSiteContainers(siteId, skipCount, maxItems, fields).getBody();
        LOGGER.info("Listing site containers [{}]: ", siteId);
        for (SiteContainerEntry siteContainerEntry: siteContainerPaging.getList().getEntries()) {
            SiteContainer siteContainer = siteContainerEntry.getEntry();
            LOGGER.info("  Site container: {}", siteContainer);
            if (siteContainer.getFolderId().equalsIgnoreCase("DocumentLibrary")) {
                docLibNodeId = siteContainer.getId();
            }
        }

        if (docLibNodeId != null) {
            // Create a folder in the document library
            createFolder(docLibNodeId, "White papers");
        } else {
            LOGGER.info("Document library not found in site {}", siteId);
        }
    }

    /**
     * Make the remote call to create a folder in the repository, if it does not exist.
     *
     * @param parentFolderId the node ID for the site container
     * @param folderName         the name of the folder
     * @return a node object for the newly created node, contains the ID,
     * such as e859588c-ae81-4c5e-a3b6-4c6109b6c905
     */
    private Node createFolder(String parentFolderId,
                              String folderName) {
        NodeBodyCreate nodeBodyCreate = new NodeBodyCreate();
        nodeBodyCreate.setName(folderName);
        nodeBodyCreate.setNodeType("cm:folder");
        Node folderNode = nodesApi.createNode(parentFolderId, nodeBodyCreate, autoRename, majorVersion, versioningEnabled,
                include, fields).getBody().getEntry();
        LOGGER.info("Created new folder in DocLib: {}", folderNode);

        return folderNode;
    }
}

Executing this code will create a folder in the passed in site’s document library:

Adding members to a site

Adding members to a site uses the createSiteMembership method of the SitesApi.

import org.alfresco.core.handler.SitesApi;
import org.alfresco.core.model.*;

    static final Logger LOGGER = LoggerFactory.getLogger(AddSiteMembersCmd.class);

    private List<String> fields = null;

    @Autowired
    SitesApi sitesApi;

    public void execute(String siteId, String personId) throws IOException {
        SiteMembershipBodyCreate siteMembershipBodyCreate = new SiteMembershipBodyCreate();
        siteMembershipBodyCreate.setId(personId);
        siteMembershipBodyCreate.setRole(SITECOLLABORATOR);
        SiteMemberEntry siteMemberEntry = sitesApi.createSiteMembership(siteId, siteMembershipBodyCreate, fields).getBody();
        LOGGER.info("Created site membership {}", siteMemberEntry);
    }
}

Executing this code will add a user with passed in ID with role Site Collaborator to site with passed in ID:

=== Managing People and Groups ===

The following sections walk through how to use the Java ReST API wrapper services when managing users and groups. Note that these are usually managed via a directory server (LDAP/Active Directory).

List people (users)

Listing people uses the listPeople method of the PeopleApi.

More info about this ReST API endpoint

For a description of the common parameters, such as fields, see this section.

import org.alfresco.core.handler.PeopleApi;
import org.alfresco.core.model.PersonEntry;
import org.alfresco.core.model.PersonPaging;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

import java.io.IOException;
import java.util.List;

@Component
public class ListPeopleCmd {
    static final Logger LOGGER = LoggerFactory.getLogger(ListPeopleCmd.class);

    @Autowired
    PeopleApi peopleApi;

    public void execute() throws IOException {
        Integer skipCount = 0;
        Integer maxItems = 100;
        List<String> orderBy = null;
        List<String> include = null;
        List<String> fields = null;

        LOGGER.info("Listing people in the repository");
        PersonPaging people = peopleApi.listPeople(skipCount, maxItems, orderBy, include, fields).getBody();
        for (PersonEntry personEntry: people.getList().getEntries()) {
            LOGGER.info("  {} ({})", personEntry.getEntry().getDisplayName(), personEntry.getEntry().getId());
        }
    }
}

Executing this code will list all users in the repository (note, if connected to LDAP this could be a lot of users…):

Get person metadata

Getting metadata for a person involves a number of API calls:

@Component
public class GetPersonMetadataCmd {
    static final Logger LOGGER = LoggerFactory.getLogger(GetPersonMetadataCmd.class);

    @Autowired
    PeopleApi peopleApi;

    @Autowired
    PreferencesApi preferencesApi;

    public void execute(String personId) throws IOException {
        Integer skipCount = 0;

        List<String> fields = null;

        PersonEntry person = peopleApi.getPerson(personId, fields).getBody();
        LOGGER.info("Got person metadata {}", person);

        PersonBodyUpdate personBodyUpdate = new PersonBodyUpdate();
        // Mandatory fields during an update
        personBodyUpdate.setFirstName("Martin");

Enable auditing and Alfresco Access audit application

See this section

List audit applications

Listing all the audit applications uses the listAuditApps method of the AuditApi.

More info about this ReST API endpoint

For a description of the common parameters, such as fields, see this section.

import org.alfresco.core.handler.AuditApi;
import org.alfresco.core.model.AuditAppEntry;
import org.alfresco.core.model.AuditAppPaging;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

import java.io.IOException;
import java.util.List;

@Component
public class ListAuditAppsCmd {
    static final Logger LOGGER = LoggerFactory.getLogger(ListAuditAppsCmd.class);

    @Autowired
    AuditApi auditApi;

    public void execute() throws IOException {
        Integer skipCount = 0;
        Integer maxItems = 100;
        List<String> fields = null;

        LOGGER.info("Listing active audit applications in the repository:");
        AuditAppPaging auditApps = auditApi.listAuditApps(skipCount, maxItems, fields).getBody();
        for (AuditAppEntry auditAppEntry: auditApps.getList().getEntries()) {
            LOGGER.info("  {}", auditAppEntry);
        }
    }
}

Executing this code will list the audit applications that have been activated, if you have enabled auditing and activated the alfresco-access audit application, then you will see the following listing of audit apps:

        AuditApp auditApp = auditApi.getAuditApp(auditAppId, fields, include).getBody();
        LOGGER.info("Got audit app metadata  {}", auditApp);
    }
}

Enable/Disable an audit application

Enable and disable an audit application uses the updateAuditApp method of the AuditApi.

        AuditBodyUpdate auditBodyUpdate = new AuditBodyUpdate();
        auditBodyUpdate.setIsEnabled(true);

        AuditApp auditApp = auditApi.updateAuditApp(auditAppId, auditBodyUpdate, fields).getBody();
        LOGGER.info("Enabled audit app  {}", auditApp);
    }
}

List audit entries (logs) for an audit application

Listing all the audit logs for an audit application uses the listAuditEntriesForAuditApp method of the AuditApi.

        for (AuditEntryEntry auditAppEntry: auditLogs.getList().getEntries()) {
            String username = "N/A";
            if (auditAppEntry.getEntry().getCreatedByUser() != null) {
                username = auditAppEntry.getEntry().getCreatedByUser().getId();

            LOGGER.info("  {} {} {}", auditAppEntry.getEntry().getCreatedAt(), username, log);
        }
    }
}

Note that you have to add values to the include parameter for the logs to include all the data. Also, the audit log value have been truncated for readability.

Executing this code will list the audit logs for passed in audit app id. The audit log values have been trimmed:
