Spring-Boot 使用RabbitMQ

1.安装&运行 rabbitmq

安装服务器 :brew install rabbitmq
运行Server:rabbitmq-server

安装完之后:

应用端口:15672
服务端口:5672

如果没有此命令，可以去/usr/local/Cellar/rabbitmq/3.6.6目录下找rabbitmq-server命令（具体目录，安装的时候会有）
参考 rabbitmq 安装与配置

2. 搭建环境

2.1 引入包

compile('org.springframework.boot:spring-boot-starter-amqp')

2.2 建立接收者

import java.util.concurrent.CountDownLatch;import org.springframework.stereotype.Component;@Componentpublic class Receiver {    private CountDownLatch latch = new CountDownLatch(1);    public void receiveMessage(String message) {        System.out.println("Received <" + message + ">");        latch.countDown();    }    public CountDownLatch getLatch() {        return latch;    }}

2.3 建立监听者

import com.igouc.receiveMQ.Receiver;import org.springframework.amqp.core.*;import org.springframework.amqp.rabbit.connection.ConnectionFactory;import org.springframework.amqp.rabbit.listener.SimpleMessageListenerContainer;import org.springframework.amqp.rabbit.listener.adapter.MessageListenerAdapter;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.context.annotation.Bean;@SpringBootApplicationpublic class ConfigMq {    final static String QueueName = "test-rmq";    final static String ExchangeName = "test";    @Bean    Queue queue(){        return new Queue(QueueName, false);    }    @Bean    TopicExchange exchange(){        return new TopicExchange(ExchangeName);    }    @Bean    Binding binding(Queue queue, TopicExchange topicExchange){        return BindingBuilder.bind(queue).to(topicExchange).with(ExchangeName);    }    @Bean    MessageListenerAdapter listenerAdapter(Receiver receiver) {        return new MessageListenerAdapter(receiver, "receiveMessage");    }    @Bean    SimpleMessageListenerContainer container(ConnectionFactory connectionFactory,                                             MessageListenerAdapter listenerAdapter) {        SimpleMessageListenerContainer container = new SimpleMessageListenerContainer();        container.setConnectionFactory(connectionFactory);        container.setQueueNames(QueueName);        container.setMessageListener(listenerAdapter);        return container;    }}

2.4 建立发送者

import com.igouc.receiveMQ.Receiver;import org.springframework.amqp.rabbit.core.RabbitTemplate;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.boot.CommandLineRunner;import org.springframework.stereotype.Component;import java.util.concurrent.TimeUnit;@Componentpublic class SendMQ implements CommandLineRunner{    final static String QueueName = "test-rmq";    final static String ExchangeName = "test";    @Autowired    private RabbitTemplate rabbitTemplate;    @Autowired    private Receiver receiver;    @Override    public void run(String... args) throws Exception {        System.out.println("start send message ....");        rabbitTemplate.convertAndSend(QueueName, "Hello From SendMQ"); //像        receiver.getLatch().await(10000, TimeUnit.MILLISECONDS);    }}
