本文介绍如何在Java程序中实现对ActiveMQ消息队列的远程监控，包括配置步骤、依赖引入、代码示例及动态参数配置方法。

摘要生成于 C知道，由 DeepSeek-R1 满血版支持，前往体验 >

1.需求说明

在java程序代码中获取activemq中每个队列的消息消费情况

2.需要解决以下问题

activemq远程监控配置
java代码怎么调用
如何实现动态配置相关参数

3.实现步骤

3.1activemq远程配置

进入到activemq安装目录

cd apache-activemq-5.15.6

图为测试环境路径

进入到conf目录下

修改配置文件activemq.xml

vim activemq.xml

1.找到broker节点，增加useJmx="true" brokerName可以修改也可以不修改

2.在broker节点元素内找到<managementContext> 修改

createConnector="true" connectorPort="11099" 其中connectorPort默认为1099

ps:建议修改端口号，这是一个坑，很容易出现被占用的情况导致各种bug报错

修改完成

Esc 键 :wq 保存退出。

重新启动activemq即可

cd ../bin
./activemq stop
./activemq start
./activemq status

3.2java端代码

依赖引入

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-activemq</artifactId>
</dependency>

yml配置

  messages:
    basename: i18n/Messages,i18n/Pages
    jms:
      pub-sub-domain: false   # 配置消息的类型，如果是true则表示为topic消息，如果为false表示Queue消息
    activemq:
      user: admin    # 连接用户名
      password: admin   # 连接密码
      broker-url: tcp://172.16.100.152:61616 # 消息组件的连接主机信息

yml新增配置远程监控（这些参数为自定义，在监控的java代码中会用到）

activeRemote:
    connectorPort: 11099
    connectorPath: /jmxrmi
    jmxDomain: org.apache.activemq
    connectorIp: 192.168.1.87
    brokerName: localhost

java配置类，通过此方法动态配置activemq的监控参数

package com.huajie.config;

import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

@Component
@Data
@ConfigurationProperties(prefix = "activeRemote")
public class ActivemqUtilConfig {

    private  String connectorPort;

    private  String connectorPath ;

    private  String jmxDomain ;

    private  String connectorIp;

    private String brokerName;
}

远程监控工具类

package com.huajie.utils;

import com.huajie.config.ActivemqUtilConfig;

/**
 * 消息队列工具类
 */
@Component
public class ActiveMQUtil {

    private static Log log = LogFactory.getLog(ActiveMQUtil.class);

    @Autowired
    private  ActivemqUtilConfig activemqUtilConfig;

    public Long getQueueSize(String queueName) {
        Map<String, Long> queueMap = getAllQueueSize();
        Long queueSize = 0L;
        if (queueMap.size() > 0) {
            queueSize = queueMap.get(queueName);
        }
        return queueSize;
    }

    public boolean checkedEvalQueueFinish() {
        long leaderSize = this.getQueueSize("leader.saveQuotaScore.queue");
        long leadergroupSize = this.getQueueSize("leadergroup.saveQuotaScore.queue");
        if (leaderSize == 0L && leadergroupSize == 0L) {
            return true;
        } else {
            return false;
        }
    }

    public Map<String, Long> getAllQueueSize() {
        Map<String, Long> queueMap = new HashMap<String, Long>();
        BrokerViewMBean mBean = null;
        MBeanServerConnection connection = null;
        try {
            JMXServiceURL url = new JMXServiceURL("service:jmx:rmi:///jndi/rmi://"+ activemqUtilConfig.getConnectorIp()+":" + activemqUtilConfig.getConnectorPort() + activemqUtilConfig.getConnectorPath());
            JMXConnector connector = JMXConnectorFactory.connect(url);
            connector.connect();
            connection = connector.getMBeanServerConnection();
            ObjectName name = new ObjectName(activemqUtilConfig.getJmxDomain() + ":brokerName="+activemqUtilConfig.getBrokerName()+",type=Broker");
            mBean = MBeanServerInvocationHandler.newProxyInstance(connection, name, BrokerViewMBean.class, true);
        } catch (IOException e) {
            log.error("ActiveMQUtil.getAllQueueSize", e);
        } catch (MalformedObjectNameException e) {
            log.error("ActiveMQUtil.getAllQueueSize", e);
        }

        if (mBean != null) {
            for (ObjectName queueName : mBean.getQueues()) {
                QueueViewMBean queueMBean = MBeanServerInvocationHandler.newProxyInstance(connection, queueName, QueueViewMBean.class, true);
                queueMap.put(queueMBean.getName(), queueMBean.getQueueSize());
//                System.out.println("Queue Name --- " + queueMBean.getName());// 消息队列名称
//                System.out.println("Queue Size --- " + queueMBean.getQueueSize());// 队列中剩余的消息数
//                System.out.println("Number of Consumers --- " + queueMBean.getConsumerCount());// 消费者数
//                System.out.println("Number of Dequeue ---" + queueMBean.getDequeueCount());// 出队数
            }
        }

        return queueMap;
    }

}

3.3业务调用

在执行操作之前要确定leader.saveQuotaScore.queue和leadergroup.saveQuotaScore.queue两个队列已经全部消费完，所以封装了checkedEvalQueueFinish方法

    @Autowired
    private  ActiveMQUtil activeMQUtil;

    @PostMapping("/evalExecuteSubmit")
    public @ResponseBody
    ResponseBase evalExecuteSubmit(String leadergroupId, String evalYearId, String batch) {
        if (activeMQUtil.checkedEvalQueueFinish()) {
            //业务代码 update add del
            return setResultSuccess("提交成功！");
        } else {
            return setResultFail("后台数据正在入库，请稍后再试！");
        }
    }
