1.rabiimq 安装：

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

		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-test</artifactId>
			<scope>test</scope>
		</dependency>
	</dependencies>

	<build>
		<plugins>
			<plugin>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-maven-plugin</artifactId>
			</plugin>
		</plugins>
	</build>

生产者乙方：

 @Autowired
    private RabbitTemplate rabbitTemplate;

    public void sendMsg(String msg) {

        Map<String,Object> sendContext = new HashMap<>();
        sendContext.put("name","张三");
        sendContext.put("sex","男");
        sendContext.put("msg",msg);
        rabbitTemplate.convertAndSend("tulingDirectExchange","tuling.directkey",sendContext);
    }

    /**
     * 发送到扇形交换机上
     * @param msg
     */
    public void sendMsg2Fanout(String msg) {

        rabbitTemplate.convertAndSend("tulingFanoutExchange","aaaabbdd",msg);

    }

消费者乙方：

@Component
public class TulingConsumer {

    @RabbitListener(queues ="DirectQueue")
    public void consumerMsg(Message message) {

        System.out.println("消费消息:"+message.getPayload().toString());
    }

3.配置参数：

@Bean
    public MessageConverter messageConverter() {
        return new Jackson2JsonMessageConverter();
    }


    /**
     * 直接交换机
     * @return
     */
    @Bean
    public DirectExchange tulingDirectExchange() {
        //参数 durable:表示消息是否可持久化
        //autoDelete:表示若没有队列和此交换机绑定 就直接删除该交换机
        return new DirectExchange("tulingDirectExchange",true,false);
    }


    @Bean
    public Queue tulingDirectQueue() {
        return new Queue("tulingDirectQueue",true,false,false);
    }

    @Bean
    public Binding tulingDq2De(){
        return BindingBuilder.bind(tulingDirectQueue()).to(tulingDirectExchange()).with("tuling.directkey");
    }

    /**
     * 扇形交换机
     * @return
     */
    @Bean
    public FanoutExchange tulingFanoutExchange() {
        return new FanoutExchange("tulingFanoutExchange",true,false);
    }

    @Bean
    public Queue tulingfanoutQueue1() {
        return new Queue("tulingFanoutQueue1",true,false,false);
    }

    @Bean
    public Queue tulingfanoutQueue2() {
        return new Queue("tulingFanoutQueue2",true,false,false);
    }

    @Bean
    public Binding tulingBind1() {
        return BindingBuilder.bind(tulingfanoutQueue1()).to(tulingFanoutExchange());

    }

    @Bean
    public Binding tulingBind2() {
        return BindingBuilder.bind(tulingfanoutQueue2()).to(tulingFanoutExchange());
    }

    /**
     * 主题交换机
     */
    @Bean
    public TopicExchange tulingTopicExchange() {
        return new TopicExchange("tulingTopicExchange",true,false);
    }

    @Bean
    public Queue tulingTopicQueue() {
        return new Queue("tulingTopicQueue",true,false,false);
    }

    @Bean
    public Queue tulingTopicQueue2() {
        return new Queue("tulingTopicQueue2",true,false,false);
    }

    @Bean
    public Binding topicBind1(){
        return BindingBuilder.bind(tulingTopicQueue()).to(tulingTopicExchange()).with("topic.key.#");

    }

    @Bean
    public Binding topicBind2(){
        return BindingBuilder.bind(tulingTopicQueue2()).to(tulingTopicExchange()).with("#.key");

    }

4.配置连接参数：

spring:
  rabbitmq:
    host: 47.104.128.12
    port: 5672
    virtual-host: tulingVip
    username: guest
    password: guest
    connection-timeout: 10000
    template:
      mandatory: true
