***1.伺服器端
最簡單的伺服器端接收代碼，直接把穿過倆的資料列印*

package cn.servlet;import java.io.IOException;import javax.servlet.ServletException;import javax.servlet.annotation.WebServlet;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;/** * Servlet implementation class MyServlet */@WebServlet("/MyServlet")public class MyServlet extends HttpServlet {    private static final long serialVersionUID = 1L;    /**     * @see HttpServlet#HttpServlet()     */    public MyServlet() {        super();        // TODO Auto-generated constructor stub    }    /**     * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)     */    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {        // TODO Auto-generated method stub        //堅持調用post方法        this.doPost(request, response);    }    /**     * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)     */    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {        // TODO Auto-generated method stub        //獲得資料        String name = request.getParameter("name");        String age = request.getParameter("age");        //列印資料        System.out.println(name);        System.out.println(age);    }}

2.用戶端
首先我們自訂一個線程

public class Thread1 extends Thread//資料來自布局的文本編輯框String name ;    String age;    String url;    public Thread1(String name, String age,String url){        this.name=name;        this.age=age;        this.url=url;    }

1）get方法的實現

public void doGet(){        try {        //get方法的特別注意的地方            url=url+"?name="+URLEncoder.encode(name, "utf-8")+"&age="+age;            //轉換為url對象            URL httpUrl = new URL(url);            //擷取連線物件                HttpURLConnection conn = (HttpURLConnection) httpUrl.openConnection();                //設定傳輸方法                conn.setRequestMethod("GET");                conn.setReadTimeout(5000);                //讀取輸入資料流                BufferedReader br = new BufferedReader(new InputStreamReader(conn.getInputStream()));                String str;                StringBuffer sb = new StringBuffer();                //分別放入sb                while((str=br.readLine())!=null){                    sb.append(str);                }        } catch (MalformedURLException e) {            // TODO Auto-generated catch block            e.printStackTrace();        } catch (IOException e) {            // TODO Auto-generated catch block            e.printStackTrace();        }    }

2）post方法的實現

public void doPost(){        try {            URL httpUrl = new URL(url);            HttpURLConnection conn = (HttpURLConnection) httpUrl.openConnection();            conn.setRequestMethod("POST");            conn.setReadTimeout(5000);            //注意這裡是conn.getoutputstream，而不是new出來的，這樣才能關聯起來            OutputStream out =conn.getOutputStream();            String content = "name="+name+"&age="+age;            out.write(content.getBytes());            BufferedReader br = new BufferedReader(new InputStreamReader(conn.getInputStream()));            String str;            StringBuffer sb = new StringBuffer();            while((str=br.readLine())!=null){                sb.append(str);            }        } catch (MalformedURLException e) {            // TODO Auto-generated catch block            e.printStackTrace();        } catch (IOException e) {            // TODO Auto-generated catch block            e.printStackTrace();        }    }

在run方法裡面執行的是哪個方法就使用相應的方式

@Override    public void run() {        // TODO Auto-generated method stub        super.run();    doGet();//      doPost();    }

3）用戶端輸入資料的布局簡單布置了一下就是兩個編輯文字框和一個按鈕

private EditText etName,etAge;    private Button btnReg;

4）按鈕的點擊事件

 btnReg.setOnClickListener(new OnClickListener() {            public void onClick(View arg0) {                // TODO Auto-generated method stub                //把ip地址改為自己目前的                String url = "http://192.168.191.1:8080/serve/ss";                new Thread1(etName.getText().toString(), etAge.getText().toString(), url).start();            }        });    }
