Java JMeter将结果保存到文件

在JMeterGUI中，可以很容易地添加一个监听器，例如“查看结果树”或“查看表中的结果”，并添加一个文件名

我有一个方法，它创建并运行一个测试计划，如下所示

//JMeter Engine
StandardJMeterEngine jmeter = new StandardJMeterEngine();

//JMeter initialization (properties, log levels, locale, etc)
JMeterUtils.loadJMeterProperties("/path/to/apache-jmeter-4.0/bin/jmeter.properties");
JMeterUtils.setJMeterHome("/path/to/apache-jmeter-4.0");
JMeterUtils.initLogging();// you can comment this line out to see extra log messages of i.e. DEBUG level
JMeterUtils.initLocale();

// JMeter Test Plan, basic all u JOrphan HashTree
HashTree testPlanTree = new HashTree();

// HTTP Sampler
HTTPSampler httpSampler = new HTTPSampler();
httpSampler.setDomain("example.com");
httpSampler.setPort(80);
httpSampler.setPath("/");
httpSampler.setMethod("GET");

// Loop Controller
LoopController loopController = new LoopController();
loopController.setLoops(1);
loopController.addTestElement(httpSampler);
loopController.setFirst(true);
loopController.initialize();


// Thread Group
ThreadGroup threadGroup = new ThreadGroup();
threadGroup.setNumThreads(1);
threadGroup.setRampUp(1);
threadGroup.setSamplerController(loopController);

// Test Plan
TestPlan testPlan = new TestPlan("Create JMeter Script From Java Code");

// Construct Test Plan from previously initialized elements
testPlanTree.add("testPlan", testPlan);
testPlanTree.add("loopController", loopController);
testPlanTree.add("threadGroup", threadGroup);
testPlanTree.add("httpSampler", httpSampler);

// Run Test Plan
jmeter.configure(testPlanTree);
jmeter.run();

ERROR StatusLogger No log4j2 configuration file found. Using default configuration: logging only errors to the console. Set system property 'log4j2.debug' to show Log4j2 internal initialization logging.

是否有一个方便的预制测试元素可以简单地添加到线程组，并将结果直接保存到文件中（与gui中的“在表中查看结果”侦听器的方式相同）

实现执行此任务的侦听器看起来是什么样子的

编辑：我使用ResultCollector添加了更改，它成功地保存了data.csv文件，但是，它只创建了csv列名，但从未创建任何结果

Summariser summer = null;
String summariserName = JMeterUtils.getPropDefault("summariser.name", "summary");//$NON-NLS-1$
if (summariserName.length() > 0) {
    summer = new Summariser(summariserName);
}

ResultCollector rc = new ResultCollector(summer);
rc.setFilename("C:\\Users\\user\\data.csv");
rc.setErrorLogging(true);

threadGroup.addTestElement(rc);
testPlanTree.add("rc", rc);

我的完整输出如下所示

//JMeter Engine
StandardJMeterEngine jmeter = new StandardJMeterEngine();

//JMeter initialization (properties, log levels, locale, etc)
JMeterUtils.loadJMeterProperties("/path/to/apache-jmeter-4.0/bin/jmeter.properties");
JMeterUtils.setJMeterHome("/path/to/apache-jmeter-4.0");

loopController.setLoops(1);
loopController.addTestElement(httpSampler);
loopController.setFirst(true);
loopController.initialize();


// Thread Group
ThreadGroup threadGroup = new ThreadGroup();
threadGroup.setNumThreads(1);
threadGroup.setRampUp(1);
threadGroup.setSamplerController(loopController);

// Test Plan

// Construct Test Plan from previously initialized elements
testPlanTree.add("testPlan", testPlan);
testPlanTree.add("loopController", loopController);
testPlanTree.add("threadGroup", threadGroup);
testPlanTree.add("httpSampler", httpSampler);

// Run Test Plan
jmeter.configure(testPlanTree);
jmeter.run();

错误状态记录器未找到log4j2配置文件。使用默认配置：仅将错误记录到控制台。设置系统属性“log4j2.debug”以显示log4j2内部初始化日志。

从代码中删除以下行：

threadGroup.addTestElement(rc);
testPlanTree.add("rc", rc);

并将其替换为以下内容：

testPlanTree.add(testPlanTree.getArray()[0], rc);

还要注意，如果您离开此行：

rc.setErrorLogging(true);

在.jtl结果文件中只有错误

我也没有看到任何执行的采样器，因此使用以下参考资料仔细检查您的测试计划：

结果仍然相同。我实际上正在尝试运行javasampler，但我已经使用httpsampler进行了共享。我在这里没有正确使用HttpSampler吗？我已经用底部的完整输出更新了我的帖子。我想知道打印的错误或警告是否需要解决才能使jmeter正常工作？
