Java Socket小案例（2） 上传文本

需求：客户端从本地读取文本文件，上传到服务器，服务器收到后存在本地，并向客户端反馈信息

分析：

服务端：
源：网络输入流
目的：网络输出流、文本
操作的是文本，可以用字符流，同时提高效率，可以加缓冲

//服务端public class UploadServer {    public static void main(String[] args) {        ServerSocket ss = null;        Socket s = null;        PrintWriter pw = null;        try {            ss = new ServerSocket(6666);            s = ss.accept();            String ip = s.getInetAddress().getHostAddress();            System.out.println(ip + "connected...");            BufferedReader bufIn = new BufferedReader(new InputStreamReader(                    s.getInputStream()));            pw = new PrintWriter(new FileWriter(                    "D:/Java/javaCode/Inet/src/com/tcp1/1.java"), true);            PrintWriter pwOut = new PrintWriter(new OutputStreamWriter(                    s.getOutputStream()), true);            String line = null;            while ((line = bufIn.readLine()) != null) {                pw.println(line);            }            pwOut.println("上传成功");        } catch (IOException e) {            e.printStackTrace();        } finally {            pw.close();            try {                s.close();            } catch (IOException e) {                e.printStackTrace();            }        }    }}//客户端public class UploadClient {    public static void main(String[] args) {        Socket s = null;        BufferedReader bufr = null;        try {            s = new Socket("127.0.0.1", 6666);            bufr = new BufferedReader(new InputStreamReader(                    new FileInputStream(                            "D:/Java/javaCode/Inet/src/com/tcp1/UploadClient.java")));            PrintWriter pwOut = new PrintWriter(s.getOutputStream(), true);            BufferedReader bufIn = new BufferedReader(new InputStreamReader(                    s.getInputStream()));            String line = null;            while ((line = bufr.readLine()) != null) {                pwOut.println(line);            }            s.shutdownOutput();            line = bufIn.readLine();            System.out.println(line);        } catch (IOException e) {            e.printStackTrace();        } finally {            try {                bufr.close();                s.close();            } catch (IOException e) {                e.printStackTrace();            }        }    }}

问题：

1.PrintWriter忘记写true
2.服务器读到了，但是客户端没有打印上传成功

原因

1.客户端读完文本之后，没有给一个结束标记，导致服务器还在等，以为上传没有成功

总结

1.读文本读得到回车
