基本模型
代码：
客户端
package bhz.bio; import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.Socket; public class Client { final static String ADDRESS = "127.0.0.1";
final static int PORT = 8765; public static void main(String[] args) { Socket socket = null;
BufferedReader in = null;
PrintWriter out = null; try {
socket = new Socket(ADDRESS, PORT);
in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
out = new PrintWriter(socket.getOutputStream(), true); //向服务器端发送数据
out.println("接收到客户端的请求数据...");
out.println("接收到客户端的请求数据1111...");
String response = in.readLine();
System.out.println("Client: " + response); } catch (Exception e) {
e.printStackTrace();
} finally {
if(in != null){
try {
in.close();
} catch (IOException e) {
e.printStackTrace();
}
}
if(out != null){
try {
out.close();
} catch (Exception e) {
e.printStackTrace();
}
}
if(socket != null){
try {
socket.close();
} catch (IOException e) {
e.printStackTrace();
}
}
socket = null;
}
}
}
服务端
package bhz.bio; import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket; public class Server { final static int PROT = 8765; public static void main(String[] args) { ServerSocket server = null;
try {
server = new ServerSocket(PROT);
System.out.println(" server start .. ");
//进行阻塞
Socket socket = server.accept();
//新建一个线程执行客户端的任务
new Thread(new ServerHandler(socket)).start(); } catch (Exception e) {
e.printStackTrace();
} finally {
if(server != null){
try {
server.close();
} catch (IOException e) {
e.printStackTrace();
}
}
server = null;
} } }
处理类
package bhz.bio; import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.Socket; public class ServerHandler implements Runnable{ private Socket socket ; public ServerHandler(Socket socket){
this.socket = socket;
} @Override
public void run() {
BufferedReader in = null;
PrintWriter out = null;
try {
in = new BufferedReader(new InputStreamReader(this.socket.getInputStream()));
out = new PrintWriter(this.socket.getOutputStream(), true);
String body = null;
while(true){
body = in.readLine();
if(body == null) break;
System.out.println("Server :" + body);
out.println("服务器端回送响的应数据.");
} } catch (Exception e) {
e.printStackTrace();
} finally {
if(in != null){
try {
in.close();
} catch (IOException e) {
e.printStackTrace();
}
}
if(out != null){
try {
out.close();
} catch (Exception e) {
e.printStackTrace();
}
}
if(socket != null){
try {
socket.close();
} catch (IOException e) {
e.printStackTrace();
}
}
socket = null;
} } }
