Simple image resizing service with Spring Boot

How to run

• mvn spring-boot:run
• Go to: http://localhost:8080/image/show/original/byk?reference=b1.jpg

Selectors

/image/show/{type}/byk?reference={reference}

type - One of the following: original, thumbnail, poster

reference - One of the available images: b1.jpg, b2.jpg, b3.jpg, b4.jpg, b5.jpg

Resize configuration resources/resize_configuration.json:

• Height (int), the new height of the image in pixels
• Width (int), the new width of the image in pixels
• TODO: Add more parameters and map them to the resize library.

Structure

        ImageResolver
            /      \
    ImageResizer    ImageStorage
        /
ResizeConfiguration

All requests are directed to the ImageResolver. If the selector is original, the image is retrieved directly from the ImageStorage.

If the selector has a different value, the configuration mapped to the selector is retrieved from the ResizeConfiguration. The image is resized according to the configuration by the ImageResizer, saved to the ImageStorage and sent to the client. Future requests will retrieve the resized image directly from the ImageStorage.

OBS: Resized images are saved as {selector}_originalFileName.jpg (ex: thumbnail_b1.jpg).
