process.java

里面所含源码是本人平时做程序的一些实例

package src.software0611.mxb;

import java.io.*;
import java.net.Socket;

import javax.swing.JOptionPane;

public class Process extends Thread {
	Socket socket;
	InputStream in;
	private PrintStream out;
	public final static String WEB_ROOT = "E:\\java\\WebProject\\WEB_ROOT";

	public Process(Socket s) {
		this.socket = s;
		try {
			in = socket.getInputStream();
			out = new PrintStream(socket.getOutputStream());
		} catch (IOException e) {
			e.printStackTrace();
		}
	}

	public void run() {
		String fileName = parse(in);
		sendFile(fileName);
	}

	public String parse(InputStream in) {
		BufferedReader br = new BufferedReader(new InputStreamReader(in));
		String fileName = null;

		try {
			String message = br.readLine();
			String content[] = message.split("");
			if (content.length != 3) {
				JOptionPane.showMessageDialog(null, "文件读取错误！");
				return null;
			}
			System.out.println("code:" + content[0] + ",fileName:" + content[1]
					+ "http version:" + content[2]);
			fileName = content[1];

		} catch (IOException e) {
			e.printStackTrace();
		}

		return fileName;
	}

	public void sendFile(String fileName) {

			return;
		}
