rocketMq 在windows系统上的使用

1.RocketMQ简介 

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 
下载安装包：https://github.com/alibaba/RocketMQ/releases（下载：alibaba-rocketmq-3.2.6.tar.gz）-解压安装包 
CD  D:\machine\RocketMQ-3.0.8>cd alibaba-rocketmq  

创建日志需要的路径：D:\logs\alibaba-rocketmq 


启动服务 
//启动mqnamesrv 
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  
6484 -Djava.ext.dirs=D:\machine\RocketMQ-3.0.8\alibaba-rocketmq\bin/../lib-Drocketmq.home.dir=D:\machine\RocketMQ-3.0.8\alibaba-rocketmq\bin/..-XX:MaxNewSize=512M -XX:MaxPermSize=128M -XX:NewSit abort

4140 Jps -Denv.class.path=D:\ProgramFiles\Java\jdk1.6.0_26\lib -Dapplication.home=D:\Program Files\Java\jdk1.6.0_26-Xms8m  



看日志中信息D:\logs\alibaba-rocketmq/mqnamesrv.log 
The Name Server boot success. 

//启动broker 
D:\machine\RocketMQ-3.0.8\alibaba-rocketmq>start/b bin/mqbroker.exe -n "10.57.41.19:9876">D:\logs\alibaba-rocketmq/mqbroker.log  

看日志中信息D:\logs\alibaba-rocketmq/mqbroker.log 
The broker[houchangren, 10.57.41.19:10911]boot success. 



2.项目实例 

1.      创建maven项目 

Pom.xml文件如下

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  
                SendResultsendResult = producer.send(msg);

            }  

            {  
                Messagemsg = newMessage("TopicTest3",// topic  
                      "TagC",// tag

                System.out.println(sendResult);  
            }  
         }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 

文件路径：Test/src/main/java/com/ruishenh/rocketmq/example/PushConsumer.java 
package com.ruishenh.rocketmq.example;

importcom.alibaba.rocketmq.client.consumer.listener.ConsumeConcurrentlyStatus;  
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) {  

                                     System.out.println(Thread.currentThread().getName()  
                                                        +" Receive New Messages: " + msgs.size());  

                                     MessageExtmsg = msgs.get(0);  
                                     if(msg.getTopic().equals("TopicTest1")) {  
                                               //执行TopicTest1的消费逻辑  
                                               if(msg.getTags() != null && msg.getTags().equals("TagA")) {  
                                                        //执行TagA的消费  
                                                        System.out.println(newString(msg.getBody()));  
                                               }else if (msg.getTags() != null  
                                                                 &&msg.getTags().equals("TagC")) {  
                                                        //执行TagC的消费  
                                                        System.out.println(newString(msg.getBody()));  
                                               }else if (msg.getTags() != null  
                                                                 &&msg.getTags().equals("TagD")) {  
                                                        //执行TagD的消费  
                                                        System.out.println(newString(msg.getBody()));  
                                               }  
                                     }else if (msg.getTopic().equals("TopicTest2")) {  
                                               System.out.println(newString(msg.getBody()));  
                                     }  

                                     returnConsumeConcurrentlyStatus.CONSUME_SUCCESS;  

                            }  
                   });  

                   /** 
                    * Consumer对象在使用之前必须要调用start初始化，初始化一次即可<br> 
                    */  
                   consumer.start();  

                   System.out.println("ConsumerStarted.");  
         }  
}
