java socket 프로그래밍(헤더/본문포함)

1.     Java Server

import! java.io.BufferedReader; import! java.io.File; import! java.io.FileOutputStream; import! java.io.InputStreamReader; import! java.net.ServerSocket; import! java.net.Socket;   public class TCPServer implements Runnable{ public static final int serverPort = 10200; @Override public void run(){        try{        System.out.println("대기중..");            ServerSocket serverSocket = new ServerSocket(serverPort);                          while(true)            {               Socket sock = serverSocket.accept();               System.out.println("수신중....");               try{                   BufferedReader in = new BufferedReader(new InputStreamReader(sock.getInputStream()));                  String str = in.readLine();                  System.out.println("수신중인 파일 이름 : " + str);                  File f = new File("c:\\down\\", str+".jpg");                  FileOutputStream output = new FileOutputStream(f);                  byte[] buf = new byte[1024];                                       while(sock.getInputStream().read(buf)>0)                  {                     output.write(buf);                     output.flush();                  }                  in.close();                  output.close();                  System.out.println(str+".jpg 수신완료");              }              catch(Exception e){                  System.out.println("서버 에러!!");                  e.printStackTrace();              }              finally{                  sock.close();              }            }        }        catch(Exception e){            e.printStackTrace();        } } public static void main(String[] argv){ Thread doit = new Thread(new TCPServer());        doit.start(); } }

서버소켓을 생성하고 안드로이드 에뮬레이터에서 보내오는 스트림 데이터를 설정된 경로에FileOutputStream클래스를 이용하여 저장한다.

 

 

2.     Android Client

-       TCPClient.java

package sm.bit.sock;   import! java.io.BufferedWriter; import! java.io.DataInputStream; import! java.io.DataOutputStream; import! java.io.File; import! java.io.FileInputStream; import! java.io.OutputStreamWriter; import! java.io.PrintWriter; import! java.net.InetAddress; import! java.net.Socket;   public class TCPClient implements Runnable{ private static final String serverIP="192.168.34.52"; private static final int serverPort = 10200; private String msg; public TCPClient(String msg){        super();        this.msg = msg; } @Override public void run(){ try{            InetAddress serverAddr = InetAddress.getByName(serverIP);            Socket sock = new Socket(serverAddr, serverPort);            try{             PrintWriter out = new PrintWriter(new BufferedWriter(new OutputStreamWriter(sock.getOutputStream())), true);                out.println(msg);                out.flush();                                           DataInputStream dis = new DataInputStream(new FileInputStream(new File("/mnt/sdcard/"+msg+".jpg")));                DataOutputStream dos = new DataOutputStream(sock.getOutputStream());                byte[] buf = new byte[1024];                while(dis.read(buf)>0)                {                   dos.write(buf);                   dos.flush();                }                dos.close();            }            catch(Exception e){                e.printStackTrace();            }            finally            {               sock.close();            } } catch(Exception e){              e.printStackTrace(); } } }

소켓을 생성하고 안드로이드 에뮬레이터의 sdcard에 있는 사진 파일을 검색해서DataOutputStream 클래스로 패킷화 하여 소켓으로 전송한다.

 

-       Sock.java

package sm.bit.sock; import! android.app.Activity; import! android.os.Bundle; import! android.view.View; import! android.view.View.[안내]태그제한으로등록되지않습니다-xxOnClickListener; import! android.widget.Button; import! android.widget.EditText; import! android.widget.TextView;   public class Sock extends Activity {     private EditText myet;     private TextView mytv;     private Button mybtn;     public String remsg;     @Override     public void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.main);                 myet = (EditText)findViewById(R.id.edit);         mytv = (TextView)findViewById(R.id.text);         mybtn = (Button)findViewById(R.id.sendbtn);         mybtn.set[안내]태그제한으로등록되지않습니다-xxOnClickListener(new [안내]태그제한으로등록되지않습니다-xxOnClickListener(){             @Override            public void [안내]태그제한으로등록되지않습니다-xxonClick(View v){                 if((mybtn.getText().toString() != null)&& (!mybtn.getText().toString().equals(""))){                    TCPClient tp = new TCPClient(myet.getText().toString());                    tp.run();                                          mytv.setText(myet.getText().toString());                    myet.setText("");                 }             }         });     } }
