从Linux EXTREME VPS读取文件时找不到文件exception
我使用java在Linux EXTREME VPS上存储图像
当我将它存储在我正在获得的服务器路径上时
/var/sentora/hostdata/campusguru/public_html/resources/images/bharath.png 使用以下代码读取路径
if(imagePath != null && imagePath.length() > 0 ) { byte fileContent[] = new byte[3000]; try (FileInputStream fin = new FileInputStream(new File(imagePath))) { //here the exception while(fin.read(fileContent) >= 0) { // Base64.encodeBase64(fileContent); } } imagePath = imagePath.replace("\\", "/"); byte[] imageInByte; BufferedImage originalImage = ImageIO.read(new File(imagePath)); // convert BufferedImage to byte array ByteArrayOutputStream baos = new ByteArrayOutputStream(); ImageIO.write(originalImage, "png", baos); baos.flush(); imageInByte = baos.toByteArray(); baos.close(); encodedFile = Base64.getEncoder().encodeToString(imageInByte); } stuAdmissionDetails.setStuImg(encodedFile); }
当我使用上面的代码阅读时，我得到以下exception

如何解决这个问题呢？
有没有其他方法从Linux服务器读取文件？
我认为问题是你使用了错误的文件路径。
您说您正在读取Linux服务器上的文件，而您似乎正在尝试在Windows计算机上读取它们。 从这里我推断你已经将Linux文件服务器作为SMB文件共享安装在Windows机器上……或类似的东西1 。
但是……您使用的路径看起来像Linux文件路径：
- 路径分隔符是
/。 - 该路径以“/ var / …”开头，这是UNIX / Linux系统的常见约定。
但是，如果远程安装了Linux文件系统，则应使用的文件路径是从Windows命令提示符处使用的文件路径。 可能以驱动器号开头。
（我不能告诉你它应该是什么。这取决于你如何挂载文件系统，以及远程文件服务器如何导出文件树。）
1 – 另一方面，您可能只是使用在互联网上找到的某些代码，这些代码可能完全不适合您要执行的任务。
