RocketMQ在Windows7上安装和使用（注：win8失败）
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

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. 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

/**

3. 编写消息消费者Consumer
文件路径：Test/src/main/java/com/ruishenh/rocketmq/example/PushConsumer.java

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;

});
/**
