Hi，大家好，我是编程小6，很荣幸遇见你，我把这些年在开发过程中遇到的问题或想法写出来，今天说一说
jmeter tcpclient classname_文本自定义,希望能够帮助你!!!。

JMeter提供纯TCP协议级别Sampler，如果你不觉得麻烦可以通过它来完成所有基于TCP协议的性能测试，这样一个万金油式的Sampler由于很少进入使用者的视野，因此，在实际使用中存在着许多隐藏特性和误解，本篇将对TCP Sampler使用中的一些特点进行讲解。

Mock TCP Server

为了更好的理解TCP Sampler的使用，我们将构建一个Mock TCP Server用于测试，并根据不同的TCP Sampler类型和设置进行调整，以达到直观易懂的目的，一个典型的TCP Server代码参考如下：

import java.io.BufferedReader; import java.io.IOException; import java.io.InputStream; import java.io.InputStreamReader; import java.io.PrintWriter; import java.net.ServerSocket; import java.net.Socket; import java.util.concurrent.ExecutorService; import java.util.concurrent.Executors; public class TCPServer { 
    private int port = 10009; private ServerSocket serverSocket; private ExecutorService executorService; private final int POOL_SIZE = 20; public TCPServer() throws IOException { 
    serverSocket = new ServerSocket(port); executorService = Executors.newFixedThreadPool(Runtime.getRuntime() .availableProcessors() * POOL_SIZE); } public void service() { 
    while (true) { 
    Socket socket = null; try { 
    socket = serverSocket.accept(); executorService.execute(new Handler(socket)); } catch (Exception e) { 
    e.printStackTrace(); } } } public static void main(String[] args) throws IOException { 
    new TCPServer().service(); } } class Handler implements Runnable { 
    private Socket socket = null; public Handler(Socket socket) { 
    this.socket = socket; } private BufferedReader getReader(Socket socket) throws IOException { 
    InputStream in = socket.getInputStream(); return new BufferedReader(new InputStreamReader(in)); } public void run() { 
    BufferedReader br = null; PrintWriter out = null; System.out.println("New connection accepted " + socket.getInetAddress() + ":" + socket.getPort()); try { 
    br = getReader(socket); String recv = null; recv = br.readLine(); System.out.println(recv); out = new PrintWriter(socket.getOutputStream()); out.write("Hello Client\r\n"); out.flush(); } catch (IOException e) { 
    e.printStackTrace(); } finally { 
    try { 
    if (br != null) { 
    br.close(); } if (out != null) { 
    out.close(); }
