转换误差com.thoughtworks.xstream.converters.ConversionException

Question

我正在尝试自动运行JMeter脚本。但我会跟着错误走。

信息2020-07-27 15:17:27.723侦听器将启动运行版本INFO 2020-07-27 15:17:27.751 jmeter.e：若要恢复到早期行为，请在org.apache.jmeter.engine.StandardJMeterEngine.configure(StandardJMeterEngine.java:176) at com.apache.maven.ApacheMavenJmeterIntegration.main(ApacheMavenJmeterIntegration.java:28)上定义jmeterengine.startlistenerslater=false INFO 2020-27 15:17:29.094 jmeter.u：在线程"main“java.lang.NullPointerException中设置en_US异常区域设置。

代码

package com.apache.maven;

import java.io.FileInputStream;

import org.apache.jmeter.engine.StandardJMeterEngine;
import org.apache.jmeter.save.SaveService;
import org.apache.jmeter.util.JMeterUtils;
import org.apache.jorphan.collections.HashTree;

public class ApacheMavenJmeterIntegration {

    public static void main(String[] args) throws Exception {
        // TODO Auto-generated method stub

        StandardJMeterEngine jmeter = new StandardJMeterEngine();

        JMeterUtils.loadJMeterProperties("F:/apache-jmeter-5.3/bin/jmeter.properties");
        JMeterUtils.setJMeterHome("F:/apache-jmeter-5.3");
        JMeterUtils.initLocale();
        JMeterUtils.initLogging();

        SaveService.loadProperties();
        FileInputStream in = new FileInputStream("F:\\apache-maven-3.6.3\\bin\\src\\test\\jmeter\\PlanPackage.jmx");

        HashTree testPlanTree = SaveService.loadTree(in);
        in.close();

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

    }

如果您需要在JMeter的帮助下运行JMeter Maven插件测试--您不需要编写任何代码，只需使用以下pom.xml文件：

        </plugins>

</project>

并将您的.jmx测试脚本放在相对于pom.xml的src/test/jmeter文件夹下，以便您的项目看起来如下：

- pom.xml
- src
  - test
     - jmeter
       - your-test.jmx
