RabbitMq 实现消息自动序列化和反序列化的配置

配置 

@Configuration
public class RabbitMqConfig implements RabbitListenerConfigurer {



    //以下配置RabbitMQ消息服务
    @Autowired
    public ConnectionFactory connectionFactory;

    @Bean
    public DefaultMessageHandlerMethodFactory myHandlerMethodFactory() {
        DefaultMessageHandlerMethodFactory factory = new DefaultMessageHandlerMethodFactory();
        // 这里的转换器设置实现了 通过 @Payload 注解 自动反序列化message body
        factory.setMessageConverter(new MappingJackson2MessageConverter());
        return factory;
    }

    @Override
    public void configureRabbitListeners(RabbitListenerEndpointRegistrar registrar) {
        registrar.setMessageHandlerMethodFactory(myHandlerMethodFactory());
    }

    @Bean
    public SimpleRabbitListenerContainerFactory rabbitListenerContainerFactory() {
        SimpleRabbitListenerContainerFactory factory = new SimpleRabbitListenerContainerFactory();
        factory.setConnectionFactory(connectionFactory);
