1、docker-compose安装activemq

version: '2'
services:
  activemq:
    #定义主机名
    hostname: myactivemq
    #使用的镜像
    image: webcenter/activemq
    #容器的映射端口
    ports:
      - 61616:61616
      - 8161:8161
    restart: always
    #定义挂载点
    volumes:
      - ./data/activemq:/data/activemq
      - ./var/log/activemq:/var/log/activemq

2、maven依赖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>
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.6.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
    <groupId>com.ilovewl</groupId>
    <artifactId>activemq-demo</artifactId>
    <version>1.0</version>
    <name>activemq-demo</name>
    <description>activemq Demo project for Spring Boot</description>

    <properties>
        <java.version>1.8</java.version>
    </properties>

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-activemq</artifactId>
        </dependency>
        <dependency>
            <groupId>org.apache.activemq</groupId>
            <artifactId>activemq-pool</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

</project>

3、配置文件

spring.activemq.broker-url=tcp://120.79.70.19:61616
spring.activemq.user=admin
spring.activemq.password=admin
#一开始设为true,生成bean错误，百度好像是说springboot有自己的线程池管理，后设为false
spring.activemq.pool.enabled=false
spring.activemq.pool.max-connections=50
spring.activemq.pool.idle-timeout=30000

3、消费者和生产者
消费者类

package com.ilovewl.activemqdemo.config;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.jms.annotation.JmsListener;
import org.springframework.stereotype.Component;

@Component
public class JMSConsumer {
    private final static Logger logger = LoggerFactory.getLogger(JMSConsumer.class);

    @JmsListener(destination = "springboot.queue.test")
    public void receiveQueue(String msg) {
        logger.info("接收到消息：{}",msg);
    }
}

生产者：

package com.ilovewl.activemqdemo.config;

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

import javax.jms.Destination;

@Component
public class JMSProducer {
    @Autowired
    private JmsTemplate jmsTemplate;

    public void sendMessage(Destination destination, String message) {
        this.jmsTemplate.convertAndSend(destination,message);
    }
}

4、测试类

package com.ilovewl.activemqdemo;

import com.ilovewl.activemqdemo.config.JMSProducer;
import org.apache.activemq.command.ActiveMQQueue;
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 javax.jms.Destination;

@RunWith(SpringRunner.class)
@SpringBootTest
public class ActivemqDemoApplicationTests {

    @Autowired
    private JMSProducer jmsProducer;

    @Test
    public void contextLoads() {
        Destination destination = new ActiveMQQueue("springboot.queue.test");
        for(int i=0;i<10;i++){
            jmsProducer.sendMessage(destination,"hello "+i);
        }
    }

}
