Question

我在我的应用程序中使用Eureka，Zuul，Hystrix和复合服务。 RabbitMq我用于消息队列。在运行测试用例时，我遇到了以下异常。我的测试运行正常，但得到如下例外：

Answer 1

您的队列似乎已满。使用x-max-length或x-max-length-bytes属性增加队列长度。

将Spring Cloud从Angel.SR4升级到Brixton.M4后，我遇到了类似的问题。用

替换maven依赖<artifactId>spring-cloud-starter-bus-amqp</artifactId>

<dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-stream-rabbit</artifactId> </dependency> 似乎已经解决了这个问题。根据您的依赖关系，这可能会有所帮助！
