开始看了很多网上的资料,说是配置下面的代码:

eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false

但是我的application.properties里面有这两个配置了。
最后我看了一下生成的classes目录下面,原来没有application.properties这个文件。
原来build path里面排除了这个文件,如图:

Eclipse build path

最终原因是我没有在Eclipse中转换为Maven项目并进行update。
转换为Maven项目,然后update project就OK了。

bus指定刷新/actuator/bus-refresh/{destination}没有效果,可能是冒号没有转义:esc-eureka-gateway%3a5555

@RabbitListener注解需要注解到方法上面,如果放在类上面会一直发出警告:

AmqpException: No method found for class [B
