SpringCloud中Rabbitmq的使用
1.pom配置,添加以来jar包
1 <dependency> 2 <groupId>org.springframework.cloud</groupId> 3 <artifactId>spring-cloud-starter-bus-amqp</artifactId> 4 </dependency>
2.配置文件配置
1 #RabbitMq 2 spring.rabbitmq.host=${dev.spring.rabbitmq.host} 3 spring.rabbitmq.port=${dev.spring.rabbitmq.port} 4 spring.rabbitmq.username=${dev.spring.rabbitmq.username} 5 spring.rabbitmq.password=${dev.spring.rabbitmq.password} 6 7 spring.rabbitmq.exchange=${dev.spring.rabbitmq.exchange} 8 spring.rabbitmq.routingkey=${dev.spring.rabbitmq.routingkey} 9 spring.rabbitmq.queue=${dev.spring.rabbitmq.queue}
3.rabbitmq消息发送一
1 @Autowired 2 private AmqpTemplate amqpTemplate; 3 //key:消息名称;content:消息内容 4 public void send(String key,String content) { 5 amqpTemplate.convertAndSend(key, content); 6 }
4.rabbitmq消息接收一
1 @Component 2 @EnableScheduling 3 public class ClmNeedPaperMqReciever extends ClmBaseMqReciever { 4 /** 5 *RabbitListener:rabbitmq监听;queues = "queues1":监听的队列名*称;@Payload String orderXML:接收到的消息内容 6 */ 7 @RabbitHandler 8 @RabbitListener(queues = "queues1", containerFactory = "rabbitListenerContainerFactory") 9 public void process(@Payload String orderXML) { 10 11 //处理内容 12 }
5.rabbitmq发送二
1 String MQname ="ClmClose"; 2 ConnectionFactory factory = new ConnectionFactory(); 3 factory.setHost("129.1.9.193"); 4 factory.setUsername("admin"); 5 factory.setPassword("admin"); 6 factory.setPort(5672); 7 Connection connection; 8 try { 9 connection = factory.newConnection(); 10 Channel channel = connection.createChannel(); 11 channel.queueDeclare(MQname, true, false, false, null); 12 channel.basicPublish("", MQname, null, returnJSON.getBytes("UTF-8")); 13 channel.close(); 14 connection.close();
6.rabbitmq接收二
1 /* 建立连接 */ 2 ConnectionFactory factory = new ConnectionFactory(); 3 factory.setHost("129.1.9.193");// MQ的IP 4 factory.setPort(5672);// MQ端口 5 factory.setUsername("admin");// MQ用户名 6 factory.setPassword("admin");// MQ密码 7 Connection connection = factory.newConnection(); 8 Channel channel = connection.createChannel(); 9 10 /* 声明要连接的队列 */ 11 channel.queueDeclare(QUEUE_NAME, true, false, false, null); 12 System.out.println("等待消息产生:"); 13 14 /* 创建消费者对象,用于读取消息 */ 15 QueueingConsumer consumer = new QueueingConsumer(channel); 16 channel.basicConsume(QUEUE_NAME, true, consumer); 17 18 /* 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 */ 19 while (true) { 20 QueueingConsumer.Delivery delivery = consumer.nextDelivery(); 21 String message = new String(delivery.getBody(),"UTF-8"); 22 System.out.println("收到消息'" + message + "'"); 23 }
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
1 @Component 2 @EnableScheduling 3 public class ClmNeedPaperMqReciever extends ClmBaseMqReciever { 4 5 /** 6 *RabbitListener:rabbitmq监听;queues = "queues1":监听的队 7 *列名称;@Payload String orderXML:接收到的消息内容 8 */ 9 @RabbitHandler 10 @RabbitListener(queues = "queues1", containerFactory = "rabbitListenerContainerFactory") 11 public void process(@Payload String orderXML) { 12 13 //处理内容 14 15 // 解析报文对象,将byte数组还原 16 String[] listStr = orderXML.split(","); 17 byte[] listByte = new byte[listStr.length]; 18 for (int i = 0; i < listStr.length; i++) { 19 listByte[i] = new Byte(listStr[i]); 20 } 21 orderXML = new String(listByte, "UTF-8"); 22 23 } 24 25
