java - 为 Junit 使用 spring-rabbit-test

Question

我正在尝试为 rabbitMq 监听器编写一个测试用例。我尝试使用 spring-rabbit-test 并在运行测试时出现以下错误:

Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled. 2018-03-06 17:10:50.113 ERROR 14239 --- [ main] o.s.boot.SpringApplication
: Application run failed

java.lang.IllegalStateException: Another endpoint is already registered with id 'response_queue' at org.springframework.util.Assert.state(Assert.java:73) ~[spring-core-5.0.4.RELEASE.jar:5.0.4.RELEASE] at org.springframework.amqp.rabbit.listener.RabbitListenerEndpointRegistry.registerListenerContainer(RabbitListenerEndpointRegistry.java:151) ~[spring-rabbit-2.0.2.RELEASE.jar:2.0.2.RELEASE]

我正在关注 [ https://docs.spring.io/spring-amqp/reference/htmlsingle/#testing]在他们分享的示例中，在理想情况下，监听器没有 @Component，它将成为一个组件。

现在我的测试类也试图让监听器导致上述错误。

有人可以帮助我吗？

测试配置

@Configuration    
@RabbitListenerTest
public class RabbitMQTestConfig {
    @Autowired
    MyListener myListener;
}

测试

@ActiveProfiles("test")
@RunWith(SpringRunner.class)
@SpringBootTest
public class RabbitMQTest {

    @Rule
    public BrokerRunning brokerRunning = BrokerRunning.isRunning();

    @Autowired
    private RabbitListenerTestHarness harness;

    @Test
    public void testMyListener() {

    }

}

监听器

@Component
public class MyListener {

@Autowired
MyService myService;


@RabbitListener(id = "response_queue", queues = "response")
    public void processOrder(SomeResponse someResponse) {
        myService.process(someResponse);
    }
}

是的...您需要与我们分享您的项目。它的简单变体让我们重现和播放以确定原因。

现在我无法使用非常简单的 Spring Boot 应用程序重现它:

@SpringBootApplication
public class So49129095Application {

    public static void main(String[] args) {
        SpringApplication.run(So49129095Application.class, args);
    }
}

@Component
public class MyListener {

    @RabbitListener(id = "response_queue", queuesToDeclare = @Queue("response"))
    public void processOrder(Object payload) {

    }

}

@RunWith(SpringRunner.class)
@SpringBootTest(classes = {So49129095Application.class, So49129095ApplicationTests.RabbitMQTestConfig.class})
public class So49129095ApplicationTests {

    @Rule
    public BrokerRunning brokerRunning = BrokerRunning.isRunning();

    @Autowired
    private RabbitListenerTestHarness harness;

    @Test
    public void testMyListener() {

    }

    @Configuration
    @RabbitListenerTest
    public static class RabbitMQTestConfig {

        @Autowired
        MyListener myListener;

    }

}

对我来说，我没有遗漏任何关于如何一起配置的观点。
