How to get URL Query String values

Question

I'm using Spring Framework and I want to get query string values in Controller

api/asset?param1=value&param2=value

some parameters can be empty like this

api/asset?param1=value&param2

Here is code for controller

@RequestMapping(value = "/api/assets", method = RequestMethod.GET)
public @ResponseBody String getAssetList(
        @RequestParam("limit") int limit,
        @RequestParam("offset") int offset
        ) {

}

I got it working when both parameters are given, but I cannot get values when one parameter is empty

If the parameter is empty, it is a bad formed query string.

Parameters are mandatory by default but you can set them as optional.

Take a look at spring documentation here:

http://docs.spring.io/spring/docs/3.1.x/spring-framework-reference/htmlsingle/spring-framework-reference.html#mvc-ann-requestparam

Parameters using this annotation are required by default, but you can specify that a parameter is optional by setting @RequestParam's required attribute to false (e.g., @RequestParam(value="id", required=false)).
