上傳txt文本 通過socket向服務端發送數據 然後用serversocket 接收socket 通過流讀取數據保存 服務端在發送確認信息並在client輸出

client

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.Socket;
import java.net.UnknownHostException;


public class txtClient {

	/**
	 * @param args
	 * @throws IOException 
	 * @throws UnknownHostException 
	 */
	public static void main(String[] args) throws UnknownHostException, IOException {
		// TODO Auto-generated method stub

		Socket s = new Socket("10.64.130.51", 10002);
		
		BufferedReader br =
			new BufferedReader(new FileReader("F:\\fd.txt"));
		
		PrintWriter pw = new PrintWriter(s.getOutputStream(), true);
		
		String str = null;
		
		
		while((str = br.readLine()) != null){
			//System.out.println(str);
			pw.println(str);
		}
		pw.println("over");
