基于Java Socket的文件UpLoad代码

写了份文件对传的简单代码,可以把本地文件夹里的文件传递到Server端。

Server端代码:

import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.ServerSocket;
import java.net.Socket;

public class FileUpLoadProjServer extends Thread {

public FileUpLoadProjServer(Socket s, String c) throws IOException {
}

public void run() {
}

public static void main(String[] args) {
try {
ServerSocket server = new ServerSocket(8110);
Socket connection = null;
while (true) {
try {
connection = server.accept();
InputStreamReader in = new InputStreamReader(connection
.getInputStream());

long time = System.currentTimeMillis();
String t = "C:\\temp_" + time;
File myFile = null;
if ((new File(t).mkdir())) {
myFile = new File(t + "\\temp.txt");
} else {
System.out.println("Create folder failed!");
}

FileOutputStream fos = new FileOutputStream(myFile);

int ch = 0;

while ((ch = in.read()) != -1) {
System.out.print((char) ch);
fos.write(ch);
}
fos.close();
connection.close();
} catch (IOException ioe) {
System.err.println(ioe);
} finally {
try {
if (connection != null)
connection.close();
} catch (IOException e) {
}
}
}
} catch (IOException ee) {
System.err.println(ee);
}
}
}

Client端代码:

import java.io.BufferedWriter;
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.OutputStreamWriter;
import java.io.PrintWriter;
import java.net.InetAddress;
import java.net.Socket;

public class FileUpLoadProjClient extends Thread {

private Socket socket;
private PrintWriter out;
final int port = 8110;
String path = "C:\\src\\test";

public FileUpLoadProjClient(InetAddress addr) {
try {
socket = new Socket(addr, port);
} catch (IOException e) {

}

try {
out = new PrintWriter(new BufferedWriter(new OutputStreamWriter(
socket.getOutputStream())), true);
start();
} catch (IOException e) {
try {
socket.close();
} catch (IOException e2) {
}
}
}

public void run() {
try {
File root = new File(path);
String[] colum = root.list();
System.out.println("The file's num is :" + colum.length);

for (int i = 0; i < colum.length; i++) {
System.out.println("The colum's content is :" + colum[i]);
String filePath = path + "\\" + colum[i];
System.out.println("The file's absolutePath is :" + filePath);
FileInputStream fis = new FileInputStream(filePath);
int ch = 0;

while ((ch = fis.read()) != -1) {
System.out.print((char) ch);
out.write(ch);
}
fis.close();
}
out.close();
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
socket.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}

public static void main(String[] args) throws IOException,
InterruptedException {
InetAddress addr = InetAddress.getByName("127.0.0.1");
new FileUpLoadProjClient(addr);
}

}

瞎写的,凑合着用吧。
