[FIXED] Create two methods for the same URL pattern with different arguments (with argument and without argument)

Issue

I'd like to use one URL mapping /all with request parameters (month, date) or without parameters.

I've tried to create two methods, one without parameters:

@RequestMapping(value = "/all", method = RequestMethod.GET)
public CommonResponse getAll() {

}

And one with parameters:

@RequestMapping(value = "/all", method = RequestMethod.GET)
public CommonResponse getByMonth(@RequestParam int month, @RequestParam(required = false) int year) {

}

But i am getting "Ambiguous mapping found" IllegalStateException. Does Spring have any way to handle this situation?

Note:- Please don't suggest this solution because I have different scenario.

Solution

I got the solution :)

@RequestMapping(value = "/all", method = RequestMethod.GET)
public CommonResponse getAll(@RequestParam(required = false) Optional<Integer> month, 
                             @RequestParam(required = false, defaultValue = "0") int year) {

    if (month.isPresent()) {
       return getByMonth(month.get, year);
    }

    return getAll();
}
