You can use the @RequestParam annotation on method parameters

@RequestMapping (...)
public String getBooks(@RequestParam(required = false, value = "sortby") String sortBy, @RequestParam(required = false, value = "year") String year) {...}

The @RequestParam annotation also has a defaultValue attribute to use as a value if the request parameter isn't provided. Without it, if the parameter is not provided, null will be passed as the argument for that parameter.
