JAX-WS @DefaultValue annotation is being ignored

I am using Spring MCV and if I annotate my controller method with the DefaultValue annotation I am getting a serialization error 

@RequestMapping(value = "/page", method = RequestMethod.GET)
page(@DefaultValue("10") @QueryParam("pageSize") int pageSize

Returns the following error if I don't pass the pageSize parameter to the controller:

Optional int parameter 'pageSize' is present but cannot be translated into a null value due to being declared as a primitive type. Consider declaring it as object wrapper for the corresponding primitive type.

Am I misusing DefaultValue here?

Solution

  • You are mixing two implemetation, Spring and JAX-RS, if you are using Spring then you can have code like:

    @RequestMapping(value = "/page", method = RequestMethod.GET)
    public String page(@RequestParam(name = "pageSize", defaultValue = "10") int pageSize) {

}
