RelationshipListener

The following example will show you how to implement one of these interfaces and how to configure this plugin. The following step is similar to the Profile notifications implementation.

1. Create the RelationshipLoggerListener class:



import org.exoplatform.social.core.relationship.Relationship;

import org.exoplatform.social.core.relationship.lifecycle.RelationshipListenerPlugin;

import org.exoplatform.social.relationship.spi.RelationshipEvent;


public class RelationshipLoggerListener extends RelationshipListenerPlugin{

  private static final Log logger = ExoLogger.getExoLogger(RelationshipLoggerListener.class);


  @Override

  public void confirmed(RelationshipEvent event) {

    String[] names = getUserNamesFromEvent(event);

    logger.info(names[0] +" confirmed the invitation of "+ names[1]);

  }


  @Override

  public void ignored(RelationshipEvent event) {

    String[] names = getUserNamesFromEvent(event);

    logger.info(names[0] +" ignored the invitation of "+ names[1]);

  }


  @Override

  public void removed(RelationshipEvent event) {

    String[] names = getUserNamesFromEvent(event);

    logger.info(names[0] +" removed the relationship with "+ names[1]);

  }


  private String[] getUserNamesFromEvent(RelationshipEvent event){

    Relationship relationship = event.getPayload();


    Identity id1 = relationship.getIdentity1();

    Identity id2 = relationship.getIdentity2();


    String user1 = "@" + id1.getRemoteId();

    String user2 = "@" + id2.getRemoteId();


    return new String[]{user1, user2 };

  }

}

2. Add some configurations for this class in the configuration.xml file:




<external-component-plugins>

  <target-component>org.exoplatform.social.core.relationship.RelationshipManager</target-component>

  <component-plugin>

    <name>RelationshipLoggerListener</name>

    <set-method>addListenerPlugin</set-method>

    <type>classpath.of.your.RelationshipLoggerListener</type>

  </component-plugin>

</external-component-plugins>
