RequestMapping is not identifying ?(question mark) as part of parameter passed with java REST Call

Question

Follow this :

@RequestMapping(value = {"/abcd/id={id}","/abcd?id={id}"}, method = RequestMethod.GET)

public ModelAndView test(@PathVariable("id") String id) {

I have specified two type of values above in my code. former works fine when we call the uri but later is not getting identified (i.e.) @RequestMapping is not identifying ?(question mark) as part of parameter passed.

Answer 1

You should get params on URL using @RequestParam as a method parameter.

@RequestMapping(value = "/abcd", method = RequestMethod.GET)
public void test(@RequestParam String id) {
    // your code here
}

Answer 2

Question mark in urls (and uris) is used to separate parameters from the path.

@RequestMapping takes a path as it's value attribute. Hence it shouldn't contain question marks.

So basically your first case is interpreted as a path (although a strange one) and the second one is simply wrong.
