纯用Java for Java Sampler创建新的JMeter测试

我创建了一个JMeterJava请求，并将jar复制到ext目录（

apache-JMeter-3.1\lib\ext

）。 我正试图在远程机器上运行测试。通过GUI，我可以配置和运行Java请求。 还可以使用JMX文件通过Java代码调用测试，如下所示

ClientJMeterEngine jmeter = new ClientJMeterEngine("myclient");
File file = new File(RemoteJmeterTest.class.getResource("/finalSample.jmx").getFile());
JMeterUtils.loadJMeterProperties("D:/apache-jmeter-3.1/bin/jmeter.properties");
JMeterUtils.setJMeterHome("D:/Tools/apache-jmeter-3.1");

HashTree testPlanTree = SaveService.loadTree(file); 
jmeter.configure(testPlanTree); 
jmeter.runTest(); 

现在我想纯粹用Java创建一个新的JMeter测试。但是我不知道如何配置Java采样器。 我看到了一个示例，说明了如何配置HTTP采样器。 我需要配置Java请求，而不是HTTPSampler。 请协助。

添加将执行的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()); 

如果需要执行自己的类实现接口，只需替换类名，并在需要时提供自己的参数

非常感谢。成功了。我使用

ClientJMeterEngine

在远程Jmeter服务器上运行它。您好，如何在Java代码中添加“查看结果树”，并在从Java命令行运行时查看其输出？
