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;
}

}
