添加将执行SleepTest的Java
Request采样器的示例代码如下所示：
JavaSampler javaSampler = new JavaSampler();javaSampler.setName("Java Request");javaSampler.setClassname("org.apache.jmeter.protocol.java.test.SleepTest");Arguments arguments = new Arguments();arguments.addArgument("SleepTime", "1000");arguments.addArgument("SleepMask", "0x33F");javaSampler.setArguments(arguments);javaSampler.setProperty(TestElement.TEST_CLASS, JavaSampler.class.getName());javaSampler.setProperty(TestElement.GUI_CLASS, JavaTestSamplerGui.class.getName());如果您需要执行自己的实现JavaSamplerClient接口的类，只需替换类名并在需要时提供您自己的参数即可。
