NoSuchFileException uploading image into spring boot

I am wokring on spring boot, and i have created a folder web and images floders on this path : myApp/src/web/images

And when doing 

private String saveFile(MultipartFile file, String fileName) throws IOException {
    byte[] bytes = file.getBytes();
    String imagePath = new String(this.servletContext.getRealPath(this.imagesPath) + "/" + fileName);
    Path path = Paths.get(imagePath);
    Files.write(path, bytes);
    return imagePath;
}

i got this error :

java.nio.file.NoSuchFileException: /private/var/folders/4g/wd_lgz8970sfh64zm38lwfhw0000gn/T/tomcat-docbase.8255351399752894174.8098/images/IMG_2018-01-06 15:18:48.486.jpg

where i should put the images folder in order to upload files into it successfully.

Thanks for the help

You could save images into same /myapp/src/web/image/ directory using a fairly straightforward way.

the path in your application start in myapp directory you just need to chain the folow path /usr/web/images and using a FileOutputStream object to save there.

An example below.

private String saveFile(MultipartFile file,String filename) throws IOException{
        final String imagePath = "src/web/images/"; //path
        FileOutputStream output = new FileOutputStream(imagePath+filename);
        output.write(file.getBytes());

        return imagePath+filename;
}

Second Edit

if you want to get a image via GET request you can make a method that accept a Request Parameter with the name of the image and produces IMAGE CONTENT TYPE. something like that. (this sample work with a different types of images.)

@RequestMapping(value = "/show/",produces = MediaType.IMAGE_PNG_VALUE)
    public @ResponseBody byte[]  showImage(@RequestParam("image") String image) throws IOException{
        final String imagePath = "src/web/images/";

        FileInputStream input = new FileInputStream(imagePath+image);
        return IOUtils.toByteArray(input);
    }

I'm using apache common dependency to get byte array

<dependency>
    <groupId>commons-io</groupId>
    <artifactId>commons-io</artifactId>
    <version>2.6</version>
</dependency>

i am working on spring boot, and i have created a folder web and images folders on this path : myApp/src/web/images

and this exception :

java.nio.file.NoSuchFileException: /private/var/folders/4g/wd_lgz8970sfh64zm38lwfhw0000gn/T/tomcat-docbase.8255351399752894174.8098/images/IMG_2018-01-06 15:18:48.486.jpg

At runtime the images folder created in the application source code will not be physically located in an images folder of the folder that hosts the application as this path : myApp/src/web/images is probably not considered by Spring Boot as the application is started.

In Spring Boot, you can access to static resources located in some specific folders such as static or public.
But I am not sure it will help you as you want to not only access to uploded files but also put content in the folder.

So I advise you to use another approach : put the images in a specific folder that is distinct of the application deployment folder.
Besides, generally, you want that the files be available after a shutdown/startup of the application.

So instead of using a relative path to the application to host the images :

myApp/src/web/images

use an absolute path (prefix with /) that is independently of the runtime folder of the application.
