將隊列添加到隊列中時出錯

Question

我在我的應用程序中使用了Eureka，Zuul，Hystrix和複合服務。 RabbitMq我用於消息隊列。運行測試用例時，我遇到了以下異常。我的測試運行良好，但得到的例外如下：

11:38:16.597 [task-scheduler-4] ERROR o.s.c.n.h.amqp.HystrixStreamTask -  Error adding metrics to queue

Answer 1

看起來你的隊列已滿。使用x-max-length或x-max-length-bytes屬性增加隊列長度。

我升級春雲從Angel.SR4到Brixton.M4後經歷了類似的問題。替換maven dependency <artifactId>spring-cloud-starter-bus-amqp</artifactId>與

<dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-stream-rabbit</artifactId> </dependency> 似乎已經解決了這個問題。根據您的依賴關係，這可能會有所幫助！
