在java中通过套接字将文件从客户端传输到服务器

String serverIP = "服务器IP地址";
int serverPort = 服务器端口号;

try {
    Socket socket = new Socket(serverIP, serverPort);
    // 连接成功后的操作
} catch (IOException e) {
    // 连接失败的处理
}

String filePath = "要传输的文件路径";

try (Socket socket = new Socket(serverIP, serverPort);
     FileInputStream fileInputStream = new FileInputStream(filePath);
     OutputStream outputStream = socket.getOutputStream()) {

    byte[] buffer = new byte[1024];
    int bytesRead;
    
    while ((bytesRead = fileInputStream.read(buffer)) != -1) {
        outputStream.write(buffer, 0, bytesRead);
    }
    
    outputStream.flush();
} catch (IOException e) {
    // 文件传输失败的处理
}

int serverPort = 服务器端口号;
String savePath = "文件保存路径";

try (ServerSocket serverSocket = new ServerSocket(serverPort);
     Socket socket = serverSocket.accept();
     InputStream inputStream = socket.getInputStream();
     FileOutputStream fileOutputStream = new FileOutputStream(savePath)) {

    byte[] buffer = new byte[1024];
    int bytesRead;
    
    while ((bytesRead = inputStream.read(buffer)) != -1) {
        fileOutputStream.write(buffer, 0, bytesRead);
    }
    
    fileOutputStream.flush();
} catch (IOException e) {
    // 文件接收失败的处理
}
