Spring / Spring Interview questions II
Can I make a path variable optional?
No. In spring MVC path variables are mandatory, however, we may have two controller methods that call the same service code:
@RequestMapping(value="/module/{path}", method=RequestMethod.GET) public @ResponseBody String mapRequest(HttpServletRequest req, @PathVariable String path) { return processRequest(); } @RequestMapping(value="/module", method=RequestMethod.GET) public @ResponseBody String mapRequest(HttpServletRequest req) { return processRequest(); }
