server端

package com.hjb.version.tcp;import java.io.FileOutputStream;import java.io.IOException;import java.io.InputStream;import java.io.OutputStream;import java.net.ServerSocket;import java.net.Socket;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import com.hjb.version.util.Constant;public class TcpServer {public class SocketThread extends Thread {public void run() {try {ServerSocket server = new ServerSocket(Constant.getServer_port());Socket socket = new Socket();while (true) {socket = server.accept();InputStream is = socket.getInputStream();OutputStream os = socket.getOutputStream();byte[] b = new byte[1024];// 1、得到文件名int a = is.read(b);String filename = new String(b, 0, a);System.out.println("接受到的文件名为：" + filename);FileOutputStream fos = new FileOutputStream(Constant.getUploadPath() + "\\" + filename);int length = 0;while ((length = is.read(b)) != -1) {// 2、把socket输入流写到文件输出流中去fos.write(b, 0, length);}// fos.flush();fos.close();os.flush();os.close();is.close();socket.close();}} catch (IOException e) {e.printStackTrace();}}}public static void main(String args[]) {TcpServer.SocketThread socketThread = new TcpServer().new SocketThread();socketThread.start();}}

client端

package com.hjb.version.tcp;import java.io.File;import java.io.FileInputStream;import java.io.IOException;import java.io.InputStream;import java.io.OutputStream;import java.net.Socket;import java.net.UnknownHostException;import com.hjb.version.util.Constant;public class TcpClient {public static void SendTcpTextData(String HostName, int HostPort,String filePath) throws IOException {try {              Socket client = new Socket(HostName, HostPort);              InputStream is =  client.getInputStream();              OutputStream os = client.getOutputStream();              File file = new File(filePath);              String filename = file.getName();              System.out.println("send's file name:"+filename);              //1、发送文件名              os.write(filename.getBytes());              FileInputStream fis = new FileInputStream(file);              byte[] b = new byte[1024];              int length = 0;              while((length=fis.read(b))!=-1){                  //2、把文件写入socket输出流                  os.write(b, 0, length);              }              os.close();              fis.close();            is.close();              System.out.println("send over");          } catch (UnknownHostException e) {              // TODO Auto-generated catch block              e.printStackTrace();          } catch (IOException e) {              // TODO Auto-generated catch block              e.printStackTrace();          }        }    public static void main(String args[]) throws IOException {SendTcpTextData(Constant.getServer_host(),Constant.getServer_port(), "E:\\cc_10.rar");}}
