这是代码：
客户端：
public class Client {

	static Socket client = null;
	static final int PORT = 1234;
	static final String IP = "127.0.0.1";
	static final String PATH = "savefile.xml";
//	static InputStream inputStream = null;
	static DataInputStream inputStream = null;
	static OutputStream outputStream = null;

	public static void main(String[] A) {

		init();
		receiveData1();
	}

	public static void init() {

		try {

			client = new Socket(IP, PORT);
			outputStream = new FileOutputStream(PATH);
		} catch (UnknownHostException e) {
			e.printStackTrace();
			System.out.println("未知的服务器.");
		} catch (IOException e) {
			e.printStackTrace();
			System.out.println("输入输出服务器出现异常.");
		}
	}

	public static void receiveData1() {

		try {

//			inputStream = client.getInputStream();
			inputStream= new DataInputStream(new BufferedInputStream(client.getInputStream()));
			long startTime= System.currentTimeMillis();
			String fileName= inputStream.readUTF();
			long length= inputStream.readLong();
			System.out.println("文件名以及长度:"+fileName+ " :"+ length);
			StringBuffer content= new StringBuffer();
			byte[] temp= new byte[102400];
			int numFlag= inputStream.read(temp);
			System.out.println("numFlag:"+numFlag);
			while(numFlag!= -1) {
				
				content.append(temp);
				numFlag= inputStream.read(temp);
				System.out.println("numFlag:"+numFlag);
			}
			System.out.println("接受的总时间是："+(System.currentTimeMillis()- startTime));
			SAVEINFILE(content);
		} catch (IOException e) {
			e.printStackTrace();
			System.out.println("接收服务器返回数据时出现异常.");
		}

	}

	public static void receiveData2() {

		try {

//			inputStream = client.getInputStream();
			byte[] temp= new byte[1000000];
			StringBuffer content= new StringBuffer();
			int numFlag= inputStream.read(temp);
			while(numFlag!= -1) {
				
				content.append(temp);
				numFlag= inputStream.read(temp);
			}
			System.out.println(content.toString());
			SAVEINFILE(content);
		} catch (IOException e) {
			e.printStackTrace();
			System.out.println("接收服务器返回数据时出现异常.");
		}

	}
	
	public static final void SAVEINFILE(final Object content) {
		
		
		System.out.println("content的类是："+content.getClass());
		if(content instanceof StringBuffer) {
			
			try {
				System.out.println(content);
				outputStream.write(content.toString().getBytes());
			} catch (IOException e) {
				e.printStackTrace();
				System.out.println("存储到文件中出现异常.");
			}
		}else{
			if(content instanceof String) {
				
				try {
					outputStream.write(((String) content).getBytes());
				} catch (IOException e) {
					e.printStackTrace();
					System.out.println("存储到文件中出现异常.");
				}
			}else{
				
				System.out.println("传入的参数没有定义.");
			}
		}
		CLOSE();
	}
	
	public static final void CLOSE() {
		
		try {
			
			outputStream.flush();
			inputStream.close();
			outputStream.close();
		} catch (IOException e) {
			e.printStackTrace();
			System.out.println("关闭输入输出流的时候出现异常.");
		}
		
	}
}
服务端：
public class Server {

	
	static ServerSocket server= null;
//	static OutputStream outputStream= null;
	static DataOutputStream outputStream= null;
	static InputStream inputStream= null;
	static String fileName= "";
	static long length= 0;
	static final int PORT= 1234;
	static Socket socket= null;
	static final String PATH= "E:/download/logs/test/SystemOut.log";
	
	public static void main(String[] A) {
		
		init();
		sendFile();
	}
	
	public static void init() {
		
		try {
			server= new ServerSocket(PORT);
		} catch (IOException e) {
			e.printStackTrace();
			System.out.println("服务器启动出现异常");
		}
		System.out.println("服务器已启动.");
	}
	
	public static final void saveFile(final String path, Object content) {
		
		/*try {
			
			outputStream= new FileOutputStream(path);
		} catch (FileNotFoundException e) {
			e.printStackTrace();
			System.out.println("读取文件时出现异常.");
		}*/
	}
	
	public static void readFile(final String path) {
		
		try {
			
			File file= new File(path);
			fileName= file.getName();
			length= file.length();
			inputStream= new FileInputStream(file);
		} catch (FileNotFoundException e) {
			e.printStackTrace();
			System.out.println("存储文件时出现异常.");
		}
	}
	
	public static void sendFile() {
			
			while(true) {
				
				try {
					
					socket = server.accept();
					readFile(PATH);
//					outputStream= socket.getOutputStream();
					outputStream= new DataOutputStream(new BufferedOutputStream(socket.getOutputStream()));
				} catch (IOException e) {
					e.printStackTrace();
					System.out.println("等待客户端连接时出现错误.");
				}
				System.out.println("开始发送数据.");
				try {
					
					int i= 2;
					outputStream.writeUTF(fileName);
					outputStream.flush();
					outputStream.writeLong(length);
					outputStream.flush();
					byte[] temp= new byte[1024000];
					int n= inputStream.read(temp);
					System.out.println("本次发送"+n+"个字节.");
					while(n!= -1) {
						
						System.out.println("本次发送了"+n+"个字节；"+"第"+i);
						outputStream.write(temp);
						n= inputStream.read(temp);
						i++;
					}
					CLOSE_CONNECTION();
				} catch (IOException e) {
					e.printStackTrace();
					System.out.println("发送数据时出现错误.");
				}
			}
	}
	
	public static void receiveFile() {
		
		try {
			
			inputStream= socket.getInputStream();
		} catch (IOException e) {
			e.printStackTrace();
			System.out.println("接收文件时出现异常.");
		}
	}
	
	public static final void CLOSE_CONNECTION() {
		
		try {
			outputStream.flush();
			outputStream.close();
			socket.close();
//			server.close();
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
