我想使用Spring Boot 2.0.6编写RabbitMQ的集成测试。
我打算将一个临时队列注册到现有交换机，仅用于测试，然后将其删除。每当有新消息排队时，要从RabbitMQ接收消息，我有一个MessageReceiver类，该类带有一个方法receive(...)并带有@RabbitListener注释，该方法绑定到名称来自application.properties的队列。 / p>
测试类：
@ExtendWith(SpringExtension.class)
@SpringBootTest(properties = "spring.main.allow-bean-definition-overriding=true")
//@WebAppConfiguration
@TestPropertySource("classpath:application.properties")
@TestInstance(TestInstance.Lifecycle.PER_CLASS)
@EnableRabbit
@RabbitListenerTest
public class RabbitMqIT {
private static final Logger LOGGER = LoggerFactory.getLogger(RabbitMqIT.class);
private static final Object EXCHANGE_EVENT = "service.event";
private final String QUEUE_NAME = "crm-service";
@Autowired
CachingConnectionFactory connectionFactory;
@Autowired
private RabbitTemplate rabbitTemplate;
private RabbitAdmin rabbitAdmin;
private Binding binding;
private Queue queue;
@BeforeAll
void beforeAll() {
rabbitAdmin = new RabbitAdmin(this.connectionFactory);
}
@BeforeEach
void beforeEachTestCase() {
// TODO: Get values from test configuration
connectionFactory.setUsername("admin");
connectionFactory.setPassword("admin");
connectionFactory.setHost("localhost");
connectionFactory.setPort(5672);
rabbitTemplate = new RabbitTemplate(connectionFactory);
rabbitTemplate.setQueue(QUEUE_NAME); // for receiving messages
rabbitTemplate.setRoutingKey(QUEUE_NAME); // for sending messages
// TODO: How to declare a temporary queue for the CrmMessageReceiver which listens to an already existing queue?
queue = new Queue(QUEUE_NAME, true, false, false);
rabbitAdmin.declareQueue(queue);
binding = BindingBuilder.bind(queue).to(new FanoutExchange("service.event"));
rabbitAdmin.declareBinding(binding);
// remove any message from queue if queue already existed
rabbitAdmin.purgeQueue(QUEUE_NAME, true);
Properties queueProps = rabbitAdmin.getQueueProperties(QUEUE_NAME);
Assert.assertEquals("More messages than expected are in the queue.", 0,
Integer.parseInt(queueProps.getProperty("QUEUE_MESSAGE_COUNT") == null ? "0" : queueProps.getProperty("QUEUE_MESSAGE_COUNT")));
}
// @AfterEach
@AfterAll
void afterEachTestCase() {
// rabbitAdmin.removeBinding(binding);
// rabbitAdmin.deleteQueue(QUEUE_NAME);
}
@Test
@Tag("slow")
@Tag("integration")
void publishMessage() throws IOException, InterruptedException {
final AmqpAdmin rabbitAdmin = new RabbitAdmin(this.rabbitTemplate.getConnectionFactory());
rabbitAdmin.purgeQueue(QUEUE_NAME, true);
final MessagePostProcessor processor = (Message msg) -> {
// msg.getMessageProperties().setHeader("service.eventName", "contract.status.created");
msg.getMessageProperties().setHeader("service.eventName", CrmMessageReceiver.IncomingMessageEvent.CONTRACT_STATUS_CREATED);
return msg;
};
LOGGER.debug("Publishing to exchange {}, event {}", EXCHANGE_EVENT, "contract.status.created");
final HashMap<String, Object> result = new ObjectMapper().readValue(contractMsgJson, HashMap.class);
rabbitTemplate.setMessageConverter(new Jackson2JsonMessageConverter());
rabbitTemplate.convertAndSend("service.event", QUEUE_NAME, result, processor);
final Properties queueProps = rabbitAdmin.getQueueProperties(QUEUE_NAME);
assert queueProps != null;
Assert.assertEquals("Not exactly ONE message is in the queue.", 1,
Integer.parseInt(queueProps.get("QUEUE_MESSAGE_COUNT").toString()));
}
}
这与应用程序启动时已经存在的队列配合使用很好，但是如果没有，并且我想在测试期间设置队列，Spring Boot会抱怨：

Spring Boot似乎尝试在测试开始之前向RabbitMQ注册receive(...)方法作为侦听器，因此此刻该队列不存在。
如何在动态创建的队列中注册侦听器？
