jmeter添加java请求

1.编写java类要引入jmeter的包

2.编写类要继承AbstractJavaSamplerClient

3.实现如下方法:

　　  public Arguments getDefaultParameters()；定义可用参数及默认值；  

          public void setupTest(JavaSamplerContext arg0)：可选，测试前执行，做一些初始化工作；  
          public SampleResult runTest(JavaSamplerContext arg0)；必选，实现自定义请求；  
          public void teardownTest(JavaSamplerContext arg0)：可选，测试结束时调用；

 4.编写完类,打成jar包,放入lib\ext目录下, jmeter即可发起java请求（如果报其他类没有找到的错误，返回java工程，找到java工程是否引用了其他第三方包，需要将这些包也一并放到jmeter的ext目前下，这些类才能正常被调用）
