什么是RabbitMQ？

rabbitMQ是一个开源的消息代理和队列的服务器，用来通过普通的协议在完全不同的应用之前共享数据，rabbitmq是Erlang语言编写的，并且rabbitMQ是基于AMQP协议的

 

1.创建product

 

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.1.5.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>
<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
    <java.version>1.8</java.version>
</properties>
<dependencies>
    <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>
<!-- springboot rabbitmq(amqp) -->
<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-amqp</artifactId>
    </dependency>
</dependencies>

 

server.servlet.context-path=/
server.port=8001
spring.rabbitmq.addresses=192.168.12.128:5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest
spring.rabbitmq.virtual-host=/
spring.rabbitmq.connection-timeout=15000
## 使用启用消息确认模式
spring.rabbitmq.publisher-confirms=true
##     设置return消息模式，注意要和mandatory一起去配合使用
##spring.rabbitmq.publisher-returns=true
##spring.rabbitmq.template.mandatory=true
spring.application.name=rabbit-producer
spring.http.encoding.charset=UTF-8
spring.jackson.date-format=yyyy-MM-dd HH:mm:ss
spring.jackson.time-zone=GMT+8
spring.jackson.default-property-inclusion=NON_NULL

 

@SpringBootApplication
public class Application {
public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
}
}

import java.util.UUID;
/**

@Component
public class RabbitSender {
@Autowired

     * 这里是确认消息的回调监听接口
     * 用于确认消息是否被broker所收到
     */
final RabbitTemplate.ConfirmCallback confirmCallback = new RabbitTemplate.ConfirmCallback() {

@Override
public void confirm(CorrelationData correlationData, boolean b, String s) {
            System.err.println("ack结果为：" + b+"，"+correlationData);
}
    };
/**
     * 对外发送消息的方法
     *
     * @param message    具体的消息
     * @param properties 附加额外的消息
     * @throws Exception
     */
public void send(Object message, Map<String, Object> properties) throws Exception {
        MessageHeaders mhs = new MessageHeaders(properties);
Message<?> msg = MessageBuilder.createMessage(message, mhs);
//消息确认模式

                        return message;
}
                },
correlationData);
}
}

 

test测试

 

package com.bfxy.rabbit.producer;
import com.bfxy.rabbit.producer.component.RabbitSender;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
import java.awt.*;
import java.util.HashMap;
import java.util.Map;
/**
 * @auther daiison
 * @create 2020-04-2020/4/26-11:48 上午
 **/
@RunWith(SpringRunner.class)
@SpringBootTest
public class ApplicationTest {
@Autowired
private RabbitSender rabbitSender;
@Test
public void testSender() throws Exception {
        Map<String, Object> properties = new HashMap<String, Object>();
properties.put("attr1", "12345");
properties.put("attr2", "abcde");
rabbitSender.send("hello rabbitmq", properties);
Thread.sleep(10000);
}
}

 

 

 

2. 创建consumer

</parent>
    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <java.version>1.8</java.version>
    </properties>
    <dependencies>
        <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>
<!-- springboot rabbitmq(amqp) -->
<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-amqp</artifactId>
        </dependency>
    </dependencies>
</project>

}
}

import com.rabbitmq.client.Channel;
/**

 **/
@Component
public class RabbitReceive {
/**
     * 组合使用，消息监听
     *
     * @param message

* @throws Exception
     */
@RabbitListener(bindings = @QueueBinding(
value = @Queue(value = "queue-1", durable = "true"),
exchange = @Exchange(name = "exchange-1", durable = "true", type = "topic", ignoreDeclarationExceptions = "true"),
key = "springboot.*"
)
    )
@RabbitHandler
public void onMessage(Message message, Channel channel) throws Exception {
//1.收到消息之后进行业务端消费处理
System.err.println("----------------");
System.err.println("----- 消费消息------:" + message.getPayload());
//2.处理成功之后，获取deliveryTag 进行手动的ack 签收处理
        // application 配置的手动签收模式
Long deliveryTag = (Long) message.getHeaders().get(AmqpHeaders.DELIVERY_TAG);
//手动签收 ack
channel.basicAck(deliveryTag, false);
}
}
