我在启动集成测试时遇到性能问题。
我正在尝试模拟系统的消息传递。为此，我基本上使用@MockBean在我的网关上并使用@EnableAutoConfiguration(exclude = {RabbitAutoConfiguration.class})。例子：
@RunWith(SpringRunner.class)
@SpringBootTest(classes = MyApplication.class)
@WebAppConfiguration
@DirtiesContext(classMode = DirtiesContext.ClassMode.AFTER_EACH_TEST_METHOD)
@ActiveProfiles("test")
@EnableAutoConfiguration(exclude = {RabbitAutoConfiguration.class})
public class MyTestIT {
这两个配置很好地完成了工作，我的测试运行没有问题，并且不依赖于某些外部 RabbitMQ。
但是spring boot的启动时间非常非常慢。仅此部分配置大约两分钟SimpleMessageListenerContainer, AmqpInboundChannelAdapter, EventDrivenConsumer, RabbitExchangeQueueProvisioner, etc.
日志有一些关于问题所在的提示（我删掉了很多消息，这是一个示例）：
2018-02-09 14:26:37.784 INFO [ms-project-name-service,,,] 13804 --- [ main] o.s.integration.channel.DirectChannel : Channel 'ms-project-name-service:test:-1.channel2-output' has 1 subscriber(s).

最奇怪的是这个：
2018-02-09 14:58:42.783 WARN [ms-project-name-service,,,] 208 --- [geGeQP_9Li3Jg-1] o.s.a.r.l.SimpleMessageListenerContainer : Consumer raised exception, processing can restart if the connection factory supports it. Exception summary: org.springframework.amqp.AmqpConnectException: java.net.ConnectException: Connection refused: connect
最后一个似乎他仍在尝试连接本地 RabbitMQ。
日志上有很多这样的消息。我不明白为什么即使禁用 RabbitMQAutoConfiguration 仍然会发生这种情况。如果没有 RabbitMQ 连接，Spring 如何在通道中订阅也是一个谜。
