jmeter中将响应的信息保存到本地文件的代码

jmeter做性能测试中，需要把从服务器响应回来的数据保存到本地且每次返回的数据保存到一个文档中，jmeter中可以使用“保存响应到文件”，但是服务器每次返回的数据都单独保存为一个文档，不利于数据统计。保存服务器每次返回的数据到本地的一个文件代码如下：

import org.apache.commons.io.FileUtils;

import org.apache.jmeter.config.Arguments;

importorg.apache.jmeter.protocol.java.sampler.JavaSamplerClient;

importorg.apache.jmeter.protocol.java.sampler.JavaSamplerContext;

importorg.apache.jmeter.samplers.SampleResult;

import java.io.File;

import java.io.IOException;

import java.util.ArrayList;

import java.util.List;

public class getResposeData implementsJavaSamplerClient {

   String file = "E:" + File.separator + "javatest" +File.separator + "input.txt";

   public void setupTest(JavaSamplerContext javaSamplerContext) {

    }

   public SampleResult runTest(JavaSamplerContext javaSamplerContext) {

       List<String> contents=new ArrayList<String>();

       contents.add(javaSamplerContext.getParameter("responseStr"));

       SampleResult sampleResult=new SampleResult();

       sampleResult.sampleStart();

       try {

           FileUtils.writeLines(new File(file),contents,true);

           if (true){

               sampleResult.setResponseData("保存的内容是:"+contents.get(0),"UTF-8");

               sampleResult.setSuccessful(true);

           }

       } catch (IOException e) {

           e.printStackTrace();

       }

       sampleResult.sampleEnd();

       return sampleResult;

    }

   public void teardownTest(JavaSamplerContext javaSamplerContext) {

    }

   public Arguments getDefaultParameters() {

       Arguments arguments = new Arguments();

       arguments.addArgument("responseStr","");

       return arguments;

    }

}
