关于rabbitMq.MqListener$$EnhancerBySpringCGLIB$$86e3eca0.delVm(long)' threw exception

本文链接：https://blog.youkuaiyun.com/sunfuwei521/article/details/100122181

在2019年8月21日的一条日志中，出现了一个关于RabbitMQ消息监听器执行失败的警告。具体异常是ListenerExecutionFailedException，源于调用'MqListener'的'delVm'方法时抛出的IllegalStateException。错误指出，处理方法的类'MqListener$$EnhancerBySpringCGLIB$$86e3eca0'不是实际端点bean类'MqListener$$EnhancerBySpringCGLIB$$9f8abd3e'的实例。建议检查Spring AOP代理配置，可能存在代理冲突或配置错误。

问题：配置文件中开启了两种代理方式 spring.aop.auto 如果不配置默认是 true 的状态

开启一种代理状态配置：

# Druid AOP config
spring.aop.proxy-target-class=true

spring.aop.auto=fasle
