jmeter做效能測試中，需要把從伺服器響應回來的資料儲存到本地且每次返回的資料儲存到一個文件中，jmeter中可以使用“儲存響應到檔案”，但是伺服器每次返回的資料都單獨儲存為一個文件，不利於資料統計。儲存伺服器每次返回的資料到本地的一個檔案程式碼如下：

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("儲存的內容是:"+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;

    }

}
