2.配置类
package com.soft.rabbit.server.config;

import org.springframework.amqp.core.Binding;
import org.springframework.amqp.core.BindingBuilder;
import org.springframework.amqp.core.DirectExchange;
import org.springframework.amqp.core.Queue;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
public class DirectRabbitConfig {

//队列起名：TestDirectQueue
    @Bean
    public Queue TestDirectQueue() {
        // durable:是否持久化,默认是false,持久化队列：会被存储在磁盘上，当消息代理重启时仍然存在，暂存队列：当前连接有效
        // exclusive:默认也是false，只能被当前创建的连接使用，而且当连接关闭后队列即被删除。此参考优先级高于durable
        // autoDelete:是否自动删除，当没有生产者或者消费者使用此队列，该队列会自动删除。
        // return new Queue("TestDirectQueue",true,true,false);
        //一般设置一下队列的持久化就好,其余两个就是默认false
        return new Queue("TestDirectQueue",true);
    }

    //Direct交换机起名：TestDirectExchange
    @Bean
    DirectExchange TestDirectExchange() {
      // return new DirectExchange("TestDirectExchange",true,true);
        return new DirectExchange("TestDirectExchange",true,false);
    }

    //绑定将队列和交换机绑定, 并设置用于匹配键：TestDirectRouting
    @Bean
    Binding bindingDirect() {
        return BindingBuilder.bind(TestDirectQueue()).to(TestDirectExchange()).with("TestDirectRouting");
    }

    @Bean
    DirectExchange lonelyDirectExchange() {
        return new DirectExchange("lonelyDirectExchange");
    }

}

3.生产者类
package com.soft.rabbit.server.service;

import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
import java.util.HashMap;
import java.util.Map;
import java.util.UUID;

import org.springframework.amqp.core.AmqpTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

@Component
public class DirectService {

@Autowired
    private AmqpTemplate rabbitTemplate;

    public String send() {
        String messageId = String.valueOf(UUID.randomUUID());
        String messageData = "test message, hello!";
        String createTime = LocalDateTime.now().format(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"));
        Map<String,Object> map=new HashMap<String,Object>();
        map.put("messageId",messageId);
        map.put("messageData",messageData);
        map.put("createTime",createTime);
        //将消息携带绑定键值：TestDirectRouting 发送到交换机TestDirectExchange
        rabbitTemplate.convertAndSend("TestDirectExchange", "TestDirectRouting", map);
        return "ok";
    }

}

4.启动类
package com.soft.rabbit.server;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class ServerApplication {

private static Logger logger = LoggerFactory.getLogger(ServerApplication.class);

public static void main(String[] args) {
SpringApplication.run(ServerApplication.class, args);
logger.info("server start success！");
}

}

5.bootstrap.yml
#http端口配置
server:
port: 6001
connection-timeout: 5000
tomcat:
    max-http-post-size: -1
    max-threads: 1000
    max-connections: 1000

spring:
application:
    name: soft-rabbit-server
rabbitmq:
    host: 127.0.0.1
    port: 5672
    username: guest
    password: guest

# eureka注册中心配置
eureka:
client:
    serviceUrl:
      defaultZone: http://${eureka.instance.hostname}:9001/eureka/
instance:
    instance-id: ${spring.cloud.client.ip-address}:${server.port}
    prefer-ip-address: true
    hostname: ${spring.cloud.client.ip-address}

6.消费者类
package com.soft.rabbit.client.service;

import java.util.Map;

import org.springframework.amqp.rabbit.annotation.RabbitHandler;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;

@Component
@RabbitListener(queues = "TestDirectQueue") // 监听的队列名称 TestDirectQueue
public class DirectReceiver {

@RabbitHandler
public void process(Map testMessage) {
System.out.println("DirectReceiver消费者收到消息 : " + testMessage.toString());
}

}
