Java – spring data rest: the repositoryeventhandler method was not called

I tried to add a repository EventHandler to the rest repository as follows:

@RepositoryRestResource(collectionResourceRel = "agents",path = "/agents")
public interface AgentRepository extends CrudRepository<Agent,Long> {
    // no implementation required; Spring Data will create a concrete Repository
}

I created an agenteventhandler:

@Component
@RepositoryEventHandler(Agent.class)
public class AgentEventHandler {

    /**
     * Called before {@link Agent} is persisted 
     * 
     * @param agent
     */
    @HandleBeforeSave
    public void handleBeforeSave(Agent agent) {

        System.out.println("Saving Agent " + agent.toString());

    }
}

And declare it in the @ configuration component:

@Configuration
public class RepositoryConfiguration {

    /**
     * Declare an instance of the {@link AgentEventHandler}
     *
     * @return
     */
    @Bean
    AgentEventHandler agentEvenHandler() {

        return new AgentEventHandler();
    }
}

When I publish to a rest resource, the entity is persisted, but the method handlebeforesave is never called I'm missing what

I use spring boot 1.1 5.RELEASE

Solution

Sometimes obvious mistakes are not ignored

When publishing a spring data rest resource, a beforecreateevent will be issued To capture this event, you must inject the method handlebeforesave (which is called in put and patch HTTP calls) using @ handlebeforcreate instead of @ handlebeforesave

The test successfully passed my demo app
