java socket 深入学习tomcat 自写动态服务器 tomcat

此动态服务器没有内置对象的设置，只是阐述最基本原理，

服务器：

package cn.com.test10;

import java.io.BufferedReader;
import java.io.File;
import java.io.FileInputStream;
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.HashMap;

public class t01 {

    public static void main(String[] args) {
        try {
            ServerSocket ss = new ServerSocket(8080);
            while (true) {
                Socket soc = ss.accept();
                new Thread(new ServerOO(soc)).start();
            }
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}

class ServerOO implements Runnable {
    private Socket soc;
    private BufferedReader br;
    private PrintWriter pw;
    private Request req=new Request();
    private Response res=new Response();
    public ServerOO(Socket soc) {
        this.soc = soc;
        try {
            this.br = new BufferedReader(new InputStreamReader(soc
                    .getInputStream()));
            this.pw = new PrintWriter(soc.getOutputStream(), true);

        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

    @Override
    public void run() {
        // TODO Auto-generated method stub

        String one;
        try {
            one = br.readLine();
            if (!(one.equals("GET /favicon.ico HTTP/1.1"))) {

                String str = getSS(getSS(one, " ")[1], "\?")[1];
                
                String[] element= getSS(str,"&");
                
                System.out.println(element[0]);
                for(String s:element){
                    String[] oo=getSS(s,"=");
                    req.setAttribute(oo[0], oo[1]);
                }
                res.setPw(pw);
                Serverlet  s= new Serverlet();
                s.doGet(req, res);
            }

        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        finally{
            try {
                br.close();
                pw.close();
                soc.close();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            
        }

    }

    private String[] getSS(String str, String s) {
        return str.split(s);

    }
}

class Request {
    private HashMap<String, String> map = new HashMap<String, String>();

    public void setAttribute(String str, String s) {
        map.put(str, s);
    }

    public String getAttribute(String str) {
        return map.get(str);
    }
}

class Response {
    private PrintWriter pw;

    public PrintWriter getPw() {
        return pw;
    }

    public void setPw(PrintWriter pw) {
        this.pw = pw;
    }

}

serverlet:

package cn.com.test10;

import java.io.PrintWriter;

public class Serverlet {
        public void  doGet(Request req,Response res){
            Per p = new Per();
            p.setName(req.getAttribute("name"));
            p.setAge(Integer.parseInt(req.getAttribute("age")));
            System.out.println(p);
            
            PrintWriter pw = res.getPw();
            pw.println("<!DOCTYPE HTML PUBLIC '-//W3C//DTD HTML 4.0 Transitional//EN'><HTML><HEAD><TITLE> New Document </TITLE></HEAD><BODY>"+
                      p.toString()
                      +"</BODY></HTML>");
        }
}

Per:

package cn.com.test10;

public class Per {
    private String name;
    private int age;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        System.out.println("===============setname======");
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }
 public String toString(){
     return "我叫："+name+"    我的年龄是："+age;
 }
 
}
