RocketMQ在windows上安装和eclipse开发使用

1.概述


RocketMQ是alibaba公司开源的一个纯java的开源消息中间件。

2.开发测试环境搭建

1.   安装&启动

进入到RocketMQ下载包解压的路径下

D:\machine\RocketMQ-3.0.8\RocketMQ-3.0.8>

接下来安装

执行下边的命令或者执行install.bat(在这个bat文件中的命令如下)对maven熟悉的一眼就知道是执行clean package install assembly等操作。

mvn -Dmaven.test.skip=true clean packageinstall assembly:assembly –U

操作信息如下:

 接下来把编译好的项目copy出来
D:\machine\RocketMQ-3.0.8\RocketMQ-3.0.8\target> xcopy /E alibaba-rocketmq-3.0.8  D:\machine\RocketMQ-3.0.8\
D:\machine\RocketMQ-3.0.8>dir
 驱动器 D 中的卷是 软件
 卷的序列号是000F-1D4F
 
 D:\machine\RocketMQ-3.0.8 的目录

D:\machine\RocketMQ-3.0.8>cd alibaba-rocketmq
 启动服务
D:\machine\RocketMQ-3.0.8\alibaba-rocketmq>start/b bin/mqnamesrv.exe  >D:\logs\alibaba-rocketmq/mqnamesrv.log
 可以通过jps查看一下是不是有了RocketMQ的进程,如下方的6484
C:\Users\houchangren>jps -v

 看日志中信息D:\logs\alibaba-rocketmq/mqnamesrv.log

The Name Server boot success.

2.项目实例

 2.      编写消息产生者Producer

文件路径:/gomeTest/src/main/java/com/ruishenh/rocketmq/example/Producer.java

package com.ruishenh.rocketmq.example;
 
import java.util.concurrent.TimeUnit;
 
import com.alibaba.rocketmq.client.exception.MQClientException;
import com.alibaba.rocketmq.client.producer.DefaultMQProducer;
import com.alibaba.rocketmq.client.producer.SendResult;
import com.alibaba.rocketmq.common.message.Message;
 
public classProducer {
   public static void main(String[] args) throws MQClientException,
         InterruptedException{
      /**
       * 一个应用创建一个Producer,由应用来维护此对象,可以设置为全局对象或者单例<br>
       * 注意:ProducerGroupName需要由应用来保证唯一<br>
       * ProducerGroup这个概念发送普通的消息时,作用不大,但是发送分布式事务消息时,比较关键,
       * 因为服务器会回查这个Group下的任意一个Producer
       */
      final DefaultMQProducerproducer = newDefaultMQProducer("ProducerGroupName");
      producer.setNamesrvAddr("10.57.41.19:9876");
      producer.setInstanceName("Producer");
 
      /**
       * Producer对象在使用之前必须要调用start初始化,初始化一次即可<br>
       * 注意:切记不可以在每次发送消息时,都调用start方法
       */
      producer.start();
 
      /**
       * 下面这段代码表明一个Producer对象可以发送多个topic,多个tag的消息。
       * 注意:send方法是同步调用,只要不抛异常就标识成功。但是发送成功也可会有多种状态,<br>
       * 例如消息写入Master成功,但是Slave不成功,这种情况消息属于成功,但是对于个别应用如果对消息可靠性要求极高,<br>
       * 需要对这种情况做处理。另外,消息可能会存在发送失败的情况,失败重试由应用来处理。
       */
      for (int i = 0; i < 10; i++){
         try {
            {
                Messagemsg = newMessage("TopicTest1",// topic
                      "TagA",// tag
                      "OrderID001",// key
                      ("Hello MetaQA").getBytes());// body
                SendResultsendResult = producer.send(msg);
                System.out.println(sendResult);
            }
 
            {
                Messagemsg = newMessage("TopicTest2",// topic
                      "TagB",// tag
                      "OrderID0034",// key
                      ("Hello MetaQB").getBytes());// body

            }
         }catch(Exception e) {
            e.printStackTrace();
         }
         TimeUnit.MILLISECONDS.sleep(1000);
      }
 
      /**
       * 应用退出时,要调用shutdown来清理资源,关闭网络连接,从MetaQ服务器上注销自己
       * 注意:我们建议应用在JBOSS、Tomcat等容器的退出钩子里调用shutdown方法
       */
//    producer.shutdown();
      Runtime.getRuntime().addShutdownHook(new Thread(new Runnable() {
         public void run() {
            producer.shutdown();
         }
      }));
      System.exit(0);
   }
}

 3.      编写消息消费者Consumer

importcom.alibaba.rocketmq.client.consumer.listener.MessageListenerConcurrently;
importcom.alibaba.rocketmq.client.exception.MQClientException;
importcom.alibaba.rocketmq.common.message.MessageExt;
 
public class PushConsumer {
         /**
          * 当前例子是PushConsumer用法,使用方式给用户感觉是消息从RocketMQ服务器推到了应用客户端。<br>
          * 但是实际PushConsumer内部是使用长轮询Pull方式从MetaQ服务器拉消息,然后再回调用户Listener方法<br>
          */
         publicstatic void main(String[] args) throws InterruptedException,
                            MQClientException{
                   /**
                    * 一个应用创建一个Consumer,由应用来维护此对象,可以设置为全局对象或者单例<br>
                    * 注意:ConsumerGroupName需要由应用来保证唯一
                    */
                   DefaultMQPushConsumerconsumer = new DefaultMQPushConsumer(
                                     "ConsumerGroupName");
                   consumer.setNamesrvAddr("10.57.41.19:9876");
                   consumer.setInstanceName("Consumber");
 
                   /**
                    * 订阅指定topic下tags分别等于TagA或TagC或TagD
                    */
                   consumer.subscribe("TopicTest1","TagA || TagC || TagD");
                   /**
                    * 订阅指定topic下所有消息<br>
                    * 注意:一个consumer对象可以订阅多个topic
                    */
                   consumer.subscribe("TopicTest2","*");
 
                   consumer.registerMessageListener(newMessageListenerConcurrently() {
 
                            publicConsumeConcurrentlyStatus consumeMessage(
                                               List<MessageExt>msgs, ConsumeConcurrentlyContext context) {
