Question

我正在使用以下代码从Java应用程序运行JMeter负载测试。

StandardJMeterEngine jmeter = new StandardJMeterEngine();

JMeterUtils.setJMeterHome(jmeterHome);
JMeterUtils.loadJMeterProperties(jmeterProperties);
JMeterUtils.initLogging();
JMeterUtils.initLocale();

HTTPSampler httpSampler = new HTTPSampler();
httpSampler.setDomain(host);
httpSampler.setPort(port);
httpSampler.setPath(path);
httpSampler.setMethod("GET");
httpSampler.setName("load test");

LoopController loopController = new LoopController();
loopController.setLoops(1);
loopController.setFirst(true);
loopController.initialize();

ThreadGroup threadGroup = new ThreadGroup();
threadGroup.setName("Sample Thread Group");
threadGroup.setNumThreads(userCount);
threadGroup.setRampUp(1);
threadGroup.setSamplerController(loopController);

HashTree testPlanTree = new HashTree();
TestPlan testPlan = new TestPlan("load test");
testPlanTree.add(testPlan);
HashTree threadGroupHashTree = testPlanTree.add(testPlan, threadGroup);
threadGroupHashTree.add(httpSampler);

jmeter.configure(testPlanTree);
jmeter.run();

运行此脚本后，我希望获得总平均延迟等聚合汇总值。我知道摘要报告可以登录到csv文件，然后我可以通过再次读取该文件来计算平均延迟。但我只是想知道有没有办法在没有编写和读取csv文件的情况下获得聚合值？

我已经在这里提到了以下文章和几个相关问题。

一种方法是创建像ResultCollector这样的客户类（在我的情况下，这是JmeterOutListener.java）并从那里收集值，因为您可以访问它们。您可以在sampleOccurred方法中执行任何操作。

您可以解码ResultCollector课程，并进一步了解它的功能。

         if (jmeterHome.exists()) {
             File jmeterProperties = new File(jmeterHome.getPath() + slash + "bin" + slash + "jmeter.properties");
             if (jmeterProperties.exists()) {

                 JmeterOutListener jmeterOutListener = new JmeterOutListener();
                 testPlanTree.add(testPlanTree.getArray()[0], jmeterOutListener);

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