要求:电脑上装有idea，git环境，jdk8(至少jdk8,配置好环境变量)
首先从rocketmq的github地址拉取源码： https://github.com/apache/rocketmq.git
在这里我放到了D盘
然后用idea工具打开如下
执行maven的clean命令
install命令可不执行，执行会报错 （某些测试类报错）
下面展示如何使用idea调试rocketmq源码
分别找到namesrv下的 NamesrvStartup 类，和broker下的 BrokerStartup类，分别点击启动一次，会失败先不用管。
下图右上角会出现相应启动记录:
点击Edit Configurations ，首先编辑NamesrvStartup，设置Enviroment variables
然后点击BrokerStartup设置program arguments和 Enviroment variables
在RocketMq运行主目录中创建conf、logs文件夹 ，store文件如果没有也需要创建
从RocketMq distribution部署目录中找到broker.conf、logback_broker.xml、logback_namesrv.xml
复制到新建的conf文件夹下
修改broker.conf内容如下：

brokerName = broker-a
brokerId = 0
namesrvAddr = 127.0.0.1:9876
deleteWhen = 04
fileReservedTime = 48
brokerRole = ASYNC_MASTER
flushDiskType = ASYNC_FLUSH
#存储路径
storePathRootDir = D:\\rocketmq\\store
#CommitLog存储路径
storeCommitLog = D:\\rocketmq\\store\\commitlog
# 消息队列存储路径
storePathConsumeQueue = D:\\rocketmq\\store\\consumequeue
# 消息索引存储
storePathIndex = D:\\rocketmq\\store\\index
#checkpoint 文件存储路径
storeCheckpoint = D：\\rocketmq\\store\\checkpoint
#abort 文件存储路径
abortFile = D:\\rocketmq\\store\\abort
然后再启动
NamesrvStartup 出现下图信息，说明启动成功
BrokerStartup 出现下图信息，说明启动成功
下面使用RocketMq提供的实例验证消息发送与消息消费
修改 org.apache.rocketmq.example.quickstart.Producer
点击启动生产10条消息，主题为topicHulei,控制台如下:
再修改
org.apache.rocketmq.example.quickstart.Consumer
订阅主题
点击启动如下:
消费了10条信息
至此消息发送与消息消费都成功，RocketMq调试环境已搭建好。
