RabbitMQ消息反序列化失败问题org.springframework.messaging.converter.MessageConversionException

问题描述

博主今天学习RabbitMQ的时候发生了一个这样的异常(如下)

org.springframework.amqp.rabbit.listener.exception.ListenerExecutionFailedException: Listener method could not be invoked with the incoming message

通过异常可以得知是消息反序列化的时候出问题了

因为博主的项目里面有两个Order类，一个在producer模块，一个在consumer模块，当consumer反序列化获取producer端发送的消息时，由于反序列化的ID不一样，导致了该异常

解决方法

博主将两个模块的Order类抽取出来单独建一个模块专门放实体类，原来consumer端的Order类和producer端的Order类就不要了

然后通过maven在consumer端和producer端引入rabbitmq-pojo的依赖

这样的话consumer端和producer端使用的就是同一个实体类了

这样的话反序列化异常就解决了。
