Events

Spring Data ArangoDB includes several ApplicationEvent events that your application can respond to by registering subclasses of AbstractArangoEventListener in the ApplicationContext.

The following callback methods are present in AbstractArangoEventListener:

• onAfterLoad: Called in ArangoTemplate#find and ArangoTemplate#query after the object is loaded from the database.
• onBeforeSave: Called in ArangoTemplate#insert/#update/#replace before the object is converted and send to the database.
• onAfterSave: Called in ArangoTemplate#insert/#update/#replace after the object is send to the database.
• onBeforeDelete: Called in ArangoTemplate#delete before the object is converted and send to the database.
• onAfterDelete: Called in ArangoTemplate#delete after the object is deleted from the database.

Examples

package my.mapping.events;

public class BeforePersonSavedListener extends AbstractArangoEventListener<Person> {

  @Override
  public void onBeforeSave(BeforeSaveEvent<Person> event) {
    // do some logging or data manipulation
  }

}

To register the listener add @ComponentScan with the package of your listener to your configuration class.

@Configuration
@ComponentScan("my.mapping.events")
public class MyConfiguration implements ArangoConfiguration {
  ...
