RabbitMQ + Springboot +“Hello Word”

https://www.rabbitmq.com/getstarted.html 

官网文档

我们将呼叫我们的消息发布者（发送者）发送和我们的消息消费者（接收者） Recv。发布者将连接到RabbitMQ，发送单个消息，然后退出

创建一个Send.java 根据 springboot 配置文件配置

@Component
public class Send {
    //设置类命名队列
    private final static String QUEUE_NAME = "hello";

    @Value("${spring.rabbitmq.host}")
    private  String host;
    @Value("${spring.rabbitmq.port}")
    private  int port;
    @Value("${spring.rabbitmq.username}")
    private String username;
    @Value("${spring.rabbitmq.password}")
    private String password;

    public void send(){
        //船舰到服务器的链接
        ConnectionFactory factory = new ConnectionFactory();
        factory.setPort(port);
        factory.setPassword(password);
        factory.setUsername(username);
        factory.setHost(host);
        Connection connection = null;
        Channel channel = null;
        try{
            connection = factory.newConnection();
             channel = connection.createChannel() ;
             channel.queueDeclare(QUEUE_NAME,false,false,false,null);
             for(int i = 0;i<5;i++) {
                 String value = "hello··········";
                 channel.basicPublish("", QUEUE_NAME, null, value.getBytes());
             }
        }catch (Exception e){

        }finally {
            try {
                //关闭链接 不然一直消耗
                channel.close();
                connection.close();
            }catch (Exception e){
                e.printStackTrace();
            }
        }

    }
}

配置文件

########### rabbitmq  ############
spring.rabbitmq.host=XXX.xxx.xxx.xx
spring.rabbitmq.port=xxx
spring.rabbitmq.username=xxx
spring.rabbitmq.password=xxx

启动类

    @Override
    public void run(String... args) throws Exception {
        Send.init();
        
    }

消费端接收

public static void main (String [] argv) throws Exception{
        //创建服务器的链接
        ConnectionFactory factory = new ConnectionFactory();
        //创建
        factory.setHost("xxxx.xxxx.xxxx.xxxx");
        factory.setPassword("guest");
        factory.setUsername("guest");
        factory.setPort(xxxx);
        Connection connection = factory.newConnection();
        Channel channel = connection.createChannel() ;
        channel.queueDeclare(QUEUE_NAME,false,false,false,null);
        DefaultConsumer defaultConsumer = new DefaultConsumer(channel){
            @Override
            public void handleDelivery(String consumerTag, Envelope envelope, AMQP.BasicProperties properties, byte[] body) throws IOException {
                String s = new String(body);
                System.out.println("接受到的消息:"+s);
            }
        };
        channel.basicConsume(QUEUE_NAME,true,defaultConsumer);
