How does Spring MVC @PathVariable receive parameters with multiple '/'?

Question

I was working on a file upload widget for managing images.

I wish that image paths can be received via @PathVariable in Spring MVC, such as http://localhost:8080/show/img/20181106/sample.jpg instead of http://localhost:8080/show?imagePath=/img/20181106/sample.jpg.

But / will be resolved Spring MVC, and it will always return 404 when accessing.

Is there any good way around this?

Answer 1

You can use like below.

@RequestMapping(value = "/show/{path:.+}", method = RequestMethod.GET)
public File getImage(@PathVariable String path) {
        // logic goes here
}

Here .+ is a regexp match, it will not truncate .jpg in your path.
