Send file path as @PathVariable in Spring MVC

Question

There is a task to pass file path as @PathVariable in Spring MVC to REST Service with GET request.

We can easily do it with POST sending String of file path in JSON.

How we can do with GET request and @Controller like this?

@RequestMapping(value = "/getFile", method = RequestMethod.GET)
public File getFile(@PathVariable String path) {
    // do something
}

Request:

GET /file/getFile/"/Users/user/someSourceFolder/8.jpeg"
Content-Type: application/json

You should define your controller like this:

@RequestMapping(value = "/getFile/{path:.+}", method = RequestMethod.GET)
public File getFile(@PathVariable String path) {
    // do something
}

Ok. you use to get pattern. sending get pattern url.

Use @RequestParam.

@RequestMapping(value = "/getFile", method = RequestMethod.GET)
public File getFile(@RequestParam("path") String path) {
    // do something
}

and if you use @PathVariable.

@RequestMapping(value = "/getFile/{path}", method = RequestMethod.POST)
public File getFile(@PathVariable String path) {
    // do something
}
