简单服务器开发（五）多线程服务器

处理客户端请求：

package com.zda.httpserver.core;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.Socket;

import com.zda.httpserver.util.Logger;

/**

public class HandlerRequest implements Runnable {
    public Socket clientSocket;
    public HandlerRequest(Socket clientSocket){
        this.clientSocket = clientSocket;
    }

    @Override
    public void run() {
        //处理客户端请求
        BufferedReader br = null;
        Logger.log("httpserver thread: " + Thread.currentThread().getName());
        try {
            //接收客户端消息
            br = new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));
            //打印客户端消息
            String temp = null;

        } catch (Exception e) {
