RabbitMQ07_SpringBoot与RabbitMQ的整合

创建 Springboot 项目，选择 Spring Web 和 Spring for RabbitMQ
Pom文件：

<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>
        <exclusions>
            <exclusion>

        <artifactId>spring-rabbit-test</artifactId>
        <scope>test</scope>
    </dependency>
</dependencies>

application.yml 配置文件：

spring:
  rabbitmq:
    host: 118.31.106.51
    port: 5672
    username: ems
    password: 123456
    virtual-host: /ems

发送消息的测试类（注入 RabbitTemplate）：

package com.blu.test;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
import com.blu.RabbitmqSpringbootApplication;
@SpringBootTest(classes = RabbitmqSpringbootApplication.class)
@RunWith(SpringRunner.class)
public class TestRabbitMQ {
	
	@Autowired
	private RabbitTemplate rabbitTemplate;
	
	@Test
	public void testHello() {
		rabbitTemplate.convertAndSend("hello","hello rabbitMQ!");
	}
	
	/** * work模型--公平消费 */
	@Test
	public void testWork() {
		for(int i=1;i<=20;i++) {
			rabbitTemplate.convertAndSend("work","work work!"+i);
		}
		
	}
	
	/** * fanout模型 参数1：交换机名称 参数2：routing key(无意义，填空字符串) */
	@Test
	public void testFanout() {
		rabbitTemplate.convertAndSend("logs","","fanout模型生产的消息");
	}
	
	/** * 订阅直连（Direct）模型，参数1：交换机名称，参数2：routing key */
	@Test
	public void testRoute() {
		rabbitTemplate.convertAndSend("directs","info","发送了info的key路由信息");
	}
	
	/** * 订阅（Topic）模型 */
	@Test
	public void testTopic() {
		rabbitTemplate.convertAndSend("topics","user.save","topic模型消息");
	}
}

HelloCustomer（Hello模型的消息消费者）：

注意：

1. 消费者类需要加上 @Component 注解
2. 在类上添加 @RabbitListener 注解，然后用 @RabbitHandler 指定回调方法
3. 或者直接在回调方法上添加 @RabbitListener 注解
4. 回调方法需要定义一个String 参数用于接收消息
5. 用 queuesToDeclare 参数绑定队列，用 @Queue 注解定义队列
6. @Queue 注解的 value 指定队列名，durable（持久化）默认为 “true”，autoDelete 默认为 “true”，是否独占默认为 "false"

package com.blu.hello;
import org.springframework.amqp.rabbit.annotation.Queue;
import org.springframework.amqp.rabbit.annotation.RabbitHandler;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;
/** * @Queue 注解默认定义的是持久化、非独占、非自动删除的队列 * @author BLU */
@Component
@RabbitListener(queuesToDeclare = @Queue(value = "hello",durable = "false",autoDelete = "true"))
public class HelloCustomer {
	
	@RabbitHandler
	public void helloReceive(String message) {
		System.out.println("message = "+ message);
	}
}

WorkConsumer（Work模型的消息消费者）：

package com.blu.work;
import org.springframework.amqp.rabbit.annotation.Queue;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;
@Component
public class WorkConsumer {
	@RabbitListener(queuesToDeclare = @Queue("work"))
	public void workReceive1(String message) {
		System.out.println("message1 = "+ message);
	}
	
	@RabbitListener(queuesToDeclare = @Queue("work"))
	public void workReceive2(String message) {
		System.out.println("message2 = "+ message);
	}
}

消息接收详情：

message2 = work work!2
message1 = work work!1
message1 = work work!3
message2 = work work!4
message1 = work work!5
message2 = work work!6
message1 = work work!7
message2 = work work!8
message1 = work work!9
message2 = work work!10
message2 = work work!12

message2 = work work!14
message1 = work work!13

import org.springframework.amqp.rabbit.annotation.Queue;
import org.springframework.amqp.rabbit.annotation.QueueBinding;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;
@Component
public class FanoutConsumer {
	@RabbitListener(bindings = { @QueueBinding(
			// 创建临时队列
			value = @Queue,
			// 绑定交换机，名称：logs，类型：fanout
			exchange = @Exchange(value = "logs", type = "fanout")) })
	public void fanoutReceive1(String message) {
		System.out.println("message1 = " + message);
	}
	@RabbitListener(bindings = { @QueueBinding(
			value = @Queue,
			exchange = @Exchange(value = "logs", type = "fanout")) })
	public void fanoutReceive2(String message) {
		System.out.println("message2 = " + message);
	}
}

消息接收详情：

message1 = fanout模型生产的消息
message2 = fanout模型生产的消息

RouteConsumer（订阅直连（Direct）模型的消息消费者）：

package com.blu.route;
import org.springframework.amqp.rabbit.annotation.Exchange;
import org.springframework.amqp.rabbit.annotation.Queue;
import org.springframework.amqp.rabbit.annotation.QueueBinding;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;
@Component
public class RouteConsumer {
	
	@RabbitListener(bindings = {
			@QueueBinding(
					value = @Queue,
					exchange = @Exchange(value="directs",type = "direct"),
					key = {"info","error","debug","warn"})
	})
	public void RouteReceive1(String message) {
		System.out.println("message1 = "+message);
	}
	
	@RabbitListener(bindings = {
			@QueueBinding(
					value = @Queue,
					exchange = @Exchange(value="directs",type = "direct"),
					key = {"error"})
	})
	public void RouteReceive2(String message) {
		System.out.println("message2 = "+message);
	}
}

消息接收详情：

message1 = 发送了info的key路由信息

TopicConsumer（订阅（Topic）模型的消息消费者）：

package com.blu.topic;
import org.springframework.amqp.rabbit.annotation.Exchange;
import org.springframework.amqp.rabbit.annotation.Queue;
import org.springframework.amqp.rabbit.annotation.QueueBinding;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;
@Component
public class TopicConsumer {
	
	@RabbitListener(bindings = {
			@QueueBinding(value = @Queue,exchange = @Exchange(value = "topics",type = "topic"),key= {"user.*"})
	})
	public void TopicReceive1(String message) {
		System.out.println("message1 = "+message);
	}
	
	@RabbitListener(bindings = {
			@QueueBinding(value = @Queue,exchange = @Exchange(value = "topics",type = "topic"),key= {"order.#","product.*"})
	})
	public void TopicReceive2(String message) {
		System.out.println("message2 = "+message);
	}
}
