如何在tomcat文件夹中写入文件？

Question

I have deployed my application in Apache Tomcat.

I have a folder(assets) to save the files. So want to write a file inside webapps/assets

I tried the following code for that

    private String uploadedFiles(MultipartFile files) throws IOException {
    String filePath = "../assets/users/image/" + files.getOriginalFilename();

    File file = new File(filePath);
    byte[] bytes = file.getBytes();

    FileOutputStream out = new FileOutputStream(file);
    out.write(bytes);
    out.close();

But i am getting java.io.FileNotFoundException: ../assets/myfile.jpg (The system cannot find the path specified)

How can save this file?

Note: I want this kind of folder structure. Since I will save "../assets/myfile.png" in the database to access from the client application deployed in the same server.

Answer 1

You can get the tomcat home path with

System.getProperty( "catalina.base" );

You can then add to this your path, in your case /webapps/assets

Hope this helps :)

Answer 2

Maybe I am wrong, but you should give bytes from Multipart files ! And such of kind

../assets/users/image/

is wrong. I think, you should start with root folder, or use Paths.get() nio.
