@Retryable not making retries when triggered by Integration tests In A Spring Boot Application

Question

I have a simple method in a Service in a SpringBoot Application. I have the retry mechanism setup for that method using @Retryable.
I am trying integration tests for the method in the service and the retries are not happening when the method throws an exception. The method gets executed only once.

public interface ActionService { 

@Retryable(maxAttempts = 3, backoff = @Backoff(delay = 2000))
public void perform() throws Exception;

}



@Service
public class ActionServiceImpl implements ActionService {

@Override   
public void perform() throws Exception() {

   throw new Exception();
  } 
}



@SpringBootApplication
@Import(RetryConfig.class)
public class MyApp {

public static void main(String[] args) throws Exception {
    SpringApplication.run(MyApp.class, args);
  }
}



@Configuration
@EnableRetry
public class RetryConfig {

@Bean
public ActionService actionService() { return new ActionServiceImpl(); }

}



@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration( classes= {MyApp.class}) 
@IntegrationTest({"server.port:0", "management.port:0"})
public class MyAppIntegrationTest {

@Autowired
private ActionService actionService;

public void testAction() {

  actionService.perform();

}

Your annotation @EnableRetry is at the wrong place, instead of putting it on the ActionService interface you should place it with a Spring Java based @Configuration class, in this instance with the MyApp class. With this change the retry logic should work as expected.
