How to use

getListener

method

in

org.springframework.batch.core.listener.JobListenerFactoryBean

@Test
public void testEqualityOfProxies() throws Exception {
  JobListenerWithInterface delegate = new JobListenerWithInterface();
  Object listener1 = JobListenerFactoryBean.getListener(delegate);
  Object listener2 = JobListenerFactoryBean.getListener(delegate);
  assertEquals(listener1, listener2);
}

@Test
public void testUseInHashSet() throws Exception {
  JobListenerWithInterface delegate = new JobListenerWithInterface();
  Object listener = JobListenerFactoryBean.getListener(delegate);
  Object other = JobListenerFactoryBean.getListener(delegate);
  assertTrue(listener instanceof JobExecutionListener);
  Set<JobExecutionListener> listeners = new HashSet<>();
  listeners.add((JobExecutionListener) listener);
  listeners.add((JobExecutionListener) other);
  assertTrue(listeners.contains(listener));
  assertEquals(1, listeners.size());
}

@Test
public void testAnnotationsWithOrdered() throws Exception {
  Object delegate = new Ordered() {
    @BeforeJob
    public void foo(JobExecution execution) {
    }
    @Override
    public int getOrder() {
      return 3;
    }
  };
  JobExecutionListener listener = JobListenerFactoryBean.getListener(delegate);
  assertTrue("Listener is not of correct type", listener instanceof Ordered);
  assertEquals(3, ((Ordered) listener).getOrder());
}

@Test
public void testFactoryMethod() throws Exception {
  JobListenerWithInterface delegate = new JobListenerWithInterface();
  Object listener = JobListenerFactoryBean.getListener(delegate);
  assertTrue(listener instanceof JobExecutionListener);
  ((JobExecutionListener) listener).afterJob(new JobExecution(11L));
  assertTrue(delegate.afterJobCalled);
}
