SpringBoot整合activeMQ之队列生产者

Queue

queue producer

1.新建Maven工程并设置包名类名

　　1.1 工程名 boot_mq_produce

　　1.2 包名　com.luo.boot.activemq

 

 

2.配置pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>com.luo</groupId>
    <artifactId>boot_mq_produce</artifactId>
    <version>1.0-SNAPSHOT</version>

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
            <version>2.4.2</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>

            <scope>test</scope>
            <exclusions>
                <exclusion>
                    <groupId>org.junit.vintage</groupId>
                    <artifactId>junit-vintage-engine</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-activemq</artifactId>

        </dependency>
        <dependency>
            <groupId>junit</groupId>

            <scope>test</scope>
        </dependency>
    </dependencies>

</project>

 

3.application.yml

 

 

4.配置Bean

package com.luo.boot.activemq.config;

import org.apache.activemq.command.ActiveMQQueue;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.jms.annotation.EnableJms;
import org.springframework.stereotype.Component;

import javax.jms.Queue;

@Component
@EnableJms
public class ConfigBean {

    @Value("${myqueue}")
    private String myQueue;

    @Bean
    public Queue queue(){
        return new ActiveMQQueue(myQueue);
    }
}

 

5.Queue_produce

package com.luo.boot.activemq.produce;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.core.JmsMessagingTemplate;
import org.springframework.stereotype.Component;

import javax.jms.Queue;
import java.util.UUID;

@Component
public class Queue_Produce {
    @Autowired
    private JmsMessagingTemplate jmsMessagingTemplate;

    @Autowired
    private Queue queue;

    public void produceMsg(){
        jmsMessagingTemplate.convertAndSend(queue, "****:"+ UUID.randomUUID().toString().substring(0,6));
    }
}

 

6.主启动类MainApp_Produce

package com.luo.boot.activemq;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;


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

 

7.测试单元

import com.luo.boot.activemq.MainApp_Produce;
import com.luo.boot.activemq.produce.Queue_Produce;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.web.WebAppConfiguration;

import javax.annotation.Resource;

@SpringBootTest(classes = MainApp_Produce.class)
@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
public class MyTestMQ {
    @Resource
    private Queue_Produce queue_produce;

    @Test
    public void testSend() throws Exception{
        queue_produce.produceMsg();
    }
}

 最终测试效果

 新需求：要求每间隔三秒，往MQ里推送消息

1. 修改Queue_produce，在其中新增定时投递方法

  // 间隔时间3s定投
    @Scheduled(fixedDelay = 3000)
    public void produceMsgScheduled(){
        jmsMessagingTemplate.convertAndSend(queue, "****Scheduled:"+ UUID.randomUUID().toString().substring(0,6));
        System.out.println("*********produceMsgScheduled send OK**************");

2. 修改主启动类

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

3.直接开启主启动类，间隔发消息OK
