SpringCloud中Rabbitmq的使用

1.pom配置，添加以来jar包

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

pom 配置

2.配置文件配置

 #RabbitMq
 spring.rabbitmq.host=${dev.spring.rabbitmq.host}
 spring.rabbitmq.port=${dev.spring.rabbitmq.port}
 spring.rabbitmq.username=${dev.spring.rabbitmq.username}
 spring.rabbitmq.password=${dev.spring.rabbitmq.password}
 
 spring.rabbitmq.exchange=${dev.spring.rabbitmq.exchange}
 spring.rabbitmq.routingkey=${dev.spring.rabbitmq.routingkey}
 spring.rabbitmq.queue=${dev.spring.rabbitmq.queue}

setting.properties

3.rabbitmq消息发送一

 @Autowired
 private AmqpTemplate amqpTemplate;
 //key：消息名称；content：消息内容
 public void send(String key,String content) {
     amqpTemplate.convertAndSend(key, content);
 }

发送消息

4.rabbitmq消息接收一

 @Component
 @EnableScheduling
 public class ClmNeedPaperMqReciever extends ClmBaseMqReciever {
 /**
 *RabbitListener：rabbitmq监听；queues = "queues1"：监听的队列名*称；@Payload String orderXML：接收到的消息内容
 */
 @RabbitHandler
 @RabbitListener(queues = "queues1", containerFactory = "rabbitListenerContainerFactory")
 public void process(@Payload String orderXML) {
 
     //处理内容
 }

接受消息

5.rabbitmq发送二

 String MQname ="ClmClose";
 ConnectionFactory factory = new ConnectionFactory();
 factory.setHost("129.1.9.193");
 factory.setUsername("admin");
 factory.setPassword("admin");
 factory.setPort(5672);
 Connection connection;
 try {
 connection = factory.newConnection();
 Channel channel = connection.createChannel();
 channel.queueDeclare(MQname, true, false, false, null);
 channel.basicPublish("", MQname, null, returnJSON.getBytes("UTF-8"));
 channel.close();
 connection.close();

发送mq消息

6.rabbitmq接收二

 /* 建立连接 */
 ConnectionFactory factory = new ConnectionFactory();
 factory.setHost("129.1.9.193");// MQ的IP
 factory.setPort(5672);// MQ端口
 factory.setUsername("admin");// MQ用户名
 factory.setPassword("admin");// MQ密码
 Connection connection = factory.newConnection();
 Channel channel = connection.createChannel();
 
 /* 声明要连接的队列 */
 channel.queueDeclare(QUEUE_NAME, true, false, false, null);
 System.out.println("等待消息产生：");
 
 /* 创建消费者对象，用于读取消息 */
 QueueingConsumer consumer = new QueueingConsumer(channel);
 channel.basicConsume(QUEUE_NAME, true, consumer);
 
 /* 读取队列，并且阻塞，即在读到消息之前在这里阻塞，直到等到消息，完成消息的阅读后，继续阻塞循环 */
 while (true) {
 QueueingConsumer.Delivery delivery = consumer.nextDelivery();
 String message = new String(delivery.getBody(),"UTF-8");
 System.out.println("收到消息'" + message + "'");
 }

接受mq消息

7.用接收一的方法去接收发送二的内容时需要转换，否则会出现乱码

 @Component
 @EnableScheduling
 public class ClmNeedPaperMqReciever extends ClmBaseMqReciever {
 
 /**
 *RabbitListener：rabbitmq监听；queues = "queues1"：监听的队
 *列名称；@Payload String orderXML：接收到的消息内容
 */
 @RabbitHandler
 @RabbitListener(queues = "queues1", containerFactory = "rabbitListenerContainerFactory")
 public void process(@Payload String orderXML) {
 
 //处理内容
 
 // 解析报文对象，将byte数组还原
 String[] listStr = orderXML.split(",");
 byte[] listByte = new byte[listStr.length];
 for (int i = 0; i < listStr.length; i++) {
 listByte[i] = new Byte(listStr[i]);
 }
 orderXML = new String(listByte, "UTF-8");
 
 }

接收消息
