Jmeter 从查看结果树监听器将请求详细信息写入 CSVXML

使用JMeter的查看结果树监听器，我们可以方便地将请求的详细信息写入CSV或XML文件。这对于分析性能测试结果和生成报告非常有用。接下来，我将介绍如何使用JMeter来实现这个功能，并提供一个案例代码供参考。

java
import org.apache.jmeter.JMeter;
import org.apache.jmeter.engine.StandardJMeterEngine;
import org.apache.jmeter.save.SaveService;
import org.apache.jmeter.testelement.TestPlan;
import org.apache.jmeter.threads.SetupThreadGroup;
import org.apache.jmeter.util.JMeterUtils;
import org.apache.jorphan.collections.HashTree;
public class JMeterCSVWriterExample {
    public static void main(String[] args) throws Exception {
        // 设置JMeter属性
        JMeterUtils.loadJMeterProperties("jmeter.properties");
        JMeterUtils.setJMeterHome("/path/to/jmeter/home");
        
        // 初始化JMeter引擎
        StandardJMeterEngine jmeter = new StandardJMeterEngine();
        
        // 创建测试计划
        TestPlan testPlan = new TestPlan("Example Test Plan");
        
        // 创建线程组
        SetupThreadGroup threadGroup = new SetupThreadGroup();
        threadGroup.setNumThreads(10);
        threadGroup.setRampUp(1);
        threadGroup.setSamplerController(testPlan);
        
        // 添加HTTP请求
        HTTPSamplerProxy httpSampler = new HTTPSamplerProxy();
        httpSampler.setDomain("example.com");
        httpSampler.setPort(80);
        httpSampler.setPath("/");
        httpSampler.setMethod("GET");
        
        // 添加查看结果树监听器
        ViewResultsTree viewResultsTree = new ViewResultsTree();
        
        // 添加写入结果到文件监听器
        ResultCollector resultCollector = new ResultCollector();
        resultCollector.setFilename("/path/to/result.csv");
        
        // 构建测试计划树
        HashTree testPlanTree = new HashTree();
        testPlanTree.add(testPlan, threadGroup);
        testPlanTree.add(threadGroup, httpSampler);
        testPlanTree.add(threadGroup, viewResultsTree);
        testPlanTree.add(threadGroup, resultCollector);
        
        // 配置JMeter引擎并运行测试计划
        jmeter.configure(testPlanTree);
        jmeter.run();
        
        // 保存结果到CSV文件
        SaveService.saveTree(testPlanTree, new FileOutputStream("/path/to/test.jmx"));
    }
}
