1.安装activemq(linux)

1.下载压缩包，地址链接: https://activemq.apache.org/components/classic/download/.

2.利用xshell上传压缩包到linux上，并且解压

3.进入到bin目录启动，通过./activemq start命令启动activemq

4.在宿主主机范文虚拟机ip地址加上端口号8161，会出现登录弹框叫我们输入用户名和密码，用户名和密码都是admin。如下界面即代表active安装成功

5.要注意的坑！
1）linux主机和宿主主机的防火墙都要关闭
2）linux主机和宿主主机一定要互ping得通
3）如果linux主机和宿主主机互ping得通，但是却访问不了activemq的端口，那就参考这篇文章，把conf目录下的jetty.xml文件中的地址为linux主机的ip地址，就可以访问了。文章链接: https://blog.csdn.net/fengtangjiang/article/details/108463714.

4）activemq还依赖java环境，所以linux上也要安装java环境

2.SpringBoot整合activemq案例

2.3 消息实体

package com.yl.jms.model;

import java.io.Serializable;
import java.util.Date;

public class Message implements Serializable {
    private String content;
    private Date date;

    public String getContent() {
        return content;
    }

    public void setContent(String content) {
        this.content = content;
    }

    public Date getDate() {
        return date;
    }

    public void setDate(Date date) {
        this.date = date;
    }

    @Override
    public String toString() {
        return "Message{" +
                "content='" + content + '\'' +
                ", date=" + date +
                '}';
    }
}

2.4 主程序

package com.yl.jms;

import org.apache.activemq.command.ActiveMQQueue;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;

import javax.jms.Queue;

@SpringBootApplication
public class JmsApplication {

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

    @Bean
    Queue queue() {
        return new ActiveMQQueue("yl-queue");
    }

}

2.5 定义消息的发送和接收方法

package com.yl.jms.config;

import com.yl.jms.model.Message;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.annotation.EnableJms;
import org.springframework.jms.annotation.JmsListener;
import org.springframework.jms.core.JmsMessagingTemplate;
import org.springframework.stereotype.Component;

import javax.jms.Queue;

@Component
public class JmsComponent {

    //消息发送模板
    @Autowired
    JmsMessagingTemplate jmsMessagingTemplate;
    @Autowired
    Queue queue;

    //发送消息
    public void send(Message message) {
        jmsMessagingTemplate.convertAndSend(queue,message);
    }

    //接收消息
    @JmsListener(destination = "yl-queue")
    public void receive(Message message) {
        System.out.println("message:" + message);
    }
}
