三、运行用例
　　1、主界面左侧“测试计划”，右键菜单->添加->Threads(Users)->线程组；
　　2、再选中刚才新增的"线程组"，右键菜单->添加->Sampler->Java请求；
　　3、再选中刚才新增的"Java请求"，右键菜单->添加->监视器->聚合报告；
　　4、选择想测试的类名，并在"线程组"选项中输入循环次数及并发线程数；
　　5、点击菜单栏上"运行"->启动后便开始运行，在"聚合报告"查看结果数据。
　　Tips:
　　1.若在"Java请求"选项中未找到测试用例类名： 则请先确认用例是否继承了JMeter框架的基类； 其次保证用例Jar文件在 $安装目录/lib/ext/ 下； 尝试重启JMeter。
　　2.如果对于java请求的读取仍然存在各种各样的问题，很大可能是java版本不一致造成的，jmeter编译时java版本大多为1.6，所以可以尝试将编译java类java版本保持和jmeter编译java版本的一致，或者拿到jmeter源码，在本地再次编译jmeter。
　　在这里贴上jmeter调用dubbo协议的代码：
