SpringBoot Rabbitmq接收消息

官网地址：https://docs.spring.io/spring-boot/docs/2.1.3.RELEASE/reference/htmlsingle/#boot-features-amqp

引入依赖：

  <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-amqp</artifactId>
  </dependency>

接收消息：

@Component
public class RabbitmqListener {
    @RabbitListener(queues = "queue-1",containerFactory="myFactory")
    public void consumerMsgListenerqueue1(Message content) {
        System.out.println(messageToJson(content));
    }
    @RabbitListener(queues = "queue-2")
    public void consumerMsgListenerqueue2(byte[] content) {
       // System.out.println(messageToJson(content));
    }

    public Object messageToJson(Message message){
        Jackson2JsonMessageConverter jackson2JsonMessageConverter = new Jackson2JsonMessageConverter();
        return  jackson2JsonMessageConverter.fromMessage(message);
    }
}

容器类：

@Configuration
public class RabbitmqConfig {

        @Bean
        public SimpleRabbitListenerContainerFactory myFactory(SimpleRabbitListenerContainerFactoryConfigurer configurer) {
            SimpleRabbitListenerContainerFactory factory =
                    new SimpleRabbitListenerContainerFactory();
            configurer.configure(factory, connectionFactory());
            factory.setMessageConverter(new MyMessageConverter());
            return factory;
        }

        @Bean
        public ConnectionFactory connectionFactory() {
            ConnectionFactory connectionFactory = new CachingConnectionFactory();
            ((CachingConnectionFactory) connectionFactory).setHost("47.75.152.XX0");
            ((CachingConnectionFactory) connectionFactory).setPort(5672);
            ((CachingConnectionFactory) connectionFactory).setUsername("qijie");
            ((CachingConnectionFactory) connectionFactory).setPassword("qijie.+");
//        ExecutorService service= Executors.newFixedThreadPool(20);//线程池
//        ((CachingConnectionFactory) connectionFactory).setExecutor();
            return connectionFactory;
        }
}

MyMessageConverter： 消息转换回json格式

public class MyMessageConverter implements MessageConverter {

    @Override
    public org.springframework.amqp.core.Message toMessage(Object object, MessageProperties messageProperties) throws MessageConversionException {

        return null;
    }

    @Override
    public org.springframework.amqp.core.Message toMessage(Object object, MessageProperties messageProperties, Type genericType) throws MessageConversionException {

        return null;
    }

    @Override
    public Object fromMessage(Message message) throws MessageConversionException {
        message.getMessageProperties().setContentType(MessageProperties.CONTENT_TYPE_JSON);
        return message;
    }
}
