Spring - How to upload image from folder to database

Hello im trying to do something like this:

 private Byte[] getImage() throws IOException {

        String imageUrl = ServletContext.class.getClassLoader()
                .getResource("static/anImage.jpg")
                .getFile();

        Byte[] byteObject = new Byte[imageUrl.getBytes().length];

        int i = 0;
        for (Byte b : imageUrl.getBytes()){
            byteObject[i++] = b;
        }
        return byteObject;
    }

But it's wrong. So how to pick up a file from specific directory? Thanks.

ps. I can do something like this:

 File file = new File("image.jpg");
        byte[] content = Files.readAllBytes(file.toPath());

But still its a path only from the main folder. Dont know how to program for the resources/images folder.

In Spring you can use Resources to achieve your goal:

Resource resource = new ClassPathResource("static/anImage.jpg"); 
byte[] bytes = resource.getInputStream().readAllBytes();

Don't reinvent the wheel and use e.g. Apache Commons for convert a File to byte array. Read more FileUtils.readFileToByteArray(File input)

The way you loading resources seems to be the proper one.

Ensure that the loaded file is in proper location (src/main/resources).

Do you have any particular error or stack trace which describes the issue.
