本文介绍如何使用Eclipse和JMeter通过Java Sampler进行自定义性能测试。具体步骤包括创建Java工程、编写测试类、打包成JAR文件，并在JMeter中调用。

1、在eclipse中建立一个java工程，命名为jmeter，加入jmeter的两个包。
jakarta-jmeter-2.5.1\lib\ext\ApacheJMeter_core.jar
jakarta-jmeter-2.5.1\lib\ext\ApacheJMeter_java.jar

2、编写一个java测试类。

    
   import org.apache.jmeter.config.Arguments; 
  
   import org.apache.jmeter.protocol.java.sampler.AbstractJavaSamplerClient; 
  
   import org.apache.jmeter.protocol.java.sampler.JavaSamplerContext;  
  
   import org.apache.jmeter.samplers.SampleResult; 
  
   import java.io.BufferedReader; 
  
   import java.io.InputStreamReader; 
  
   import java.io.PrintWriter; 
  
   import java.net.*; 
  
   /** 
  
    * 
  
    * @author howsky 
  
    * 
  
    */
  
   public class Test extends AbstractJavaSamplerClient { 
  
    // Sock begin---------------------------------------------- 
  
    private Socket sid; 
  
    private PrintWriter out; 
  
    private BufferedReader in; 
  
    private String ip; 
  
       private String port; 
  
    // Sock end------------------------------------------------ 
  
       private static String label = "howsky.net"; 
  
    // 测试结果 
  
    private SampleResult sr; 
  
    /** 
  
     * 初始化 
  
     */
  
    public void setupTest(JavaSamplerContext arg0) {   
  
           System.out.println("setupTest");   
  
       } 
  
    /** 
  
     * 设置请求的参数 
  
     */
  
    public Arguments getDefaultParameters() { 
  
           Arguments params = new Arguments(); 
  
           params.addArgument("ip", "192.168.0.18"); 
  
           params.addArgument("port", "8088"); 
  
           return params; 
  
       } 
  
    /** 
  
     * 运行过程 
  
     */
  
    @Override
  
    public SampleResult runTest(JavaSamplerContext arg0) { 
  
        ip = arg0.getParameter("ip");   
  
           port = arg0.getParameter("port");    
  
           sr = new SampleResult();    
  
           sr.setSampleLabel(label);   
  
           try{   
  
               sr.sampleStart(); //记录程序执行时间，以及执行结果   
  
               //发送数据   
  
               String msg = "welcome to howsky.net";   
  
               System.out.println("begin");   
  
               sendMsg(ip, Integer.parseInt(port), msg);   
  
               sr.setSuccessful(true);   
  
               System.out.println("end");   
  
           }catch(Throwable e){   
  
               sr.setSuccessful(false);   
  
           }finally{   
  
               sr.sampleEnd();   
  
           }   
  
           return sr;  
  
    } 
  
    /** 
  
     * 结束 
  
     */
  
    public void teardownTest(JavaSamplerContext arg0) { 
  
       } 
  
    /** 
  
     * 发送消息 
  
     * @param ip 
  
     * @param port 
  
     * @param msg 
  
     * @throws Exception 
  
     */
  
    private void sendMsg(String ip, int port, String msg) throws  Exception{   
  
     sid = new Socket(ip, port);  
  
     in = new BufferedReader(new InputStreamReader(sid.getInputStream())); 
  
     out = new PrintWriter(sid.getOutputStream(), true); 
  
     out.println(msg); 
  
     in.readLine(); 
  
           System.out.println("success");   
  
       } 
  
   }
