RabbitMQ（十二）——springboot整合RabbitMQ
环境搭建
一、创建一个Springboot项目
二、导入相关依赖
或者不勾选Spring for RabbitMQ,自己导入依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-amqp</artifactId>
</dependency>
三、编写配置文件
# 应用名称
spring.application.name=rabbitmq_springboot
# 应用服务 WEB 访问端口
server.port=8080
spring.rabbitmq.port=5672
spring.rabbitmq.host=192.168.137.5
spring.rabbitmq.username=admin
spring.rabbitmq.password=123
#虚拟主机
spring.rabbitmq.virtual-host=/
helloworld模型
一、编写消费者
package com.study.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;
@Component
// 生产端没有指定交换机只有routingKey和Object。
//消费方产生hello队列，放在默认的交换机(AMQP default)上。
//而默认的交换机有一个特点，只要你的routerKey的名字与这个
//交换机的队列有相同的名字，他就会自动路由上。
//生产端routingKey 叫hello ，消费端生产hello队列。
//他们就路由上了
@RabbitListener(queuesToDeclare = @Queue(value = "hello")) //表示RabbitMQ消费者,声明一个队列
public class HelloConsumer {
@RabbitHandler //当消费者从队列取出消息时的回调方法
public void receive(String message){
System.out.println("message = " + message);
}
}
二、编写生产者测试类
package com.study;
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;
@SpringBootTest(classes = RabbitmqSpringbootApplication.class)
@RunWith(SpringRunner.class)
public class TestRabbitMQ {
//注入rabbitTemplate
@Autowired
private RabbitTemplate rabbitTemplate;
//hello world
@Test
public void testHelloWorld(){
//转换和发送 1.routingKey 2.消息
rabbitTemplate.convertAndSend("hello","hello world");
}
}
三、运行生产者测试类
work工作模型
一、消费者
package com.study.work;
import org.springframework.amqp.rabbit.annotation.Queue;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;
@Component
public class WorkConsumer {
//第一个消费者
@RabbitListener(queuesToDeclare = @Queue("work")) //@RabbitListener在方法上代表它监听这个方法作为队列消费回调
public void receive1(String message){
System.out.println("message1 = " + message);
}
//第二个消费者
@RabbitListener(queuesToDeclare = @Queue("work")) //@RabbitListener在方法上代表它监听这个方法作为队列消费回调
public void receive2(String message){
System.out.println("message2 = " + message);
}
}
二、生产者
@Test
public void testWork(){
for (int i = 0; i < 10; i++) {
rabbitTemplate.convertAndSend("work","work模型");
}
}
三、运行测试
fanout广播模型
一、消费者
package com.study.fanout;
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 FanoutConsumer {
@RabbitListener(bindings = {
@QueueBinding(
value = @Queue, //创建临时队列
exchange =@Exchange(value = "logs",type = "fanout") //绑定的交换机
)
})
public void receive1(String message){
System.out.println("message1 = " + message);
}
@RabbitListener(bindings = {
@QueueBinding(
value = @Queue, //创建临时队列
exchange =@Exchange(value = "logs",type = "fanout") //绑定的交换机
)
})
public void receive2(String message){
System.out.println("message2 = " + message);
}
}
二、生产者
@Test
public void testFanout(){
rabbitTemplate.convertAndSend("logs","","Fanout模型发送的消息");
}
三、运行测试
route路由模型
一、消费者
package com.study.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,//临时队列
exchange = @Exchange(value = "directs",type = "direct"),//指定交换机名称和类型
key = {"info","error","warn"}
)
})
public void receive1(String message){
System.out.println("message1 = " + message);
}
@RabbitListener(bindings = {
@QueueBinding(
value = @Queue,//临时队列
exchange = @Exchange(value = "directs",type = "direct"),//指定交换机名称和类型
key = {"error"}
)
})
public void receive2(String message){
System.out.println("message2 = " + message);
}
}
二、生产者
@Test
public void testRoute(){
rabbitTemplate.convertAndSend("directs","error","发送info的key的路由信息");
}
三、运行测试
Topic动态路由模型
一、消费者
package com.study.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,//临时队列
exchange = @Exchange(type = "topic",name = "topics"),
key = {"user.save","user.*"}
)
})
public void receive1(String message){
System.out.println("message1 = " + message);
}
@RabbitListener(bindings = {
@QueueBinding(
value = @Queue,//临时队列
exchange = @Exchange(type = "topic",name = "topics"),
key = {"order.#","produce.#","user.*"}
)
})
public void receive2(String message){
System.out.println("message2 = " + message);
}
}
二、生产者
@Test
public void testTopic(){
rabbitTemplate.convertAndSend("topics","user.save","user.save 路由消息");
}
三、运行测试
