@RequestMapping(value = "/testonly", method = { RequestMethod.GET, RequestMethod.POST })
public ModelAndView listBooksPOST(@ModelAttribute("booksFilter") BooksFilter filter,
@RequestParam(required = false) String parameter1,
@RequestParam(required = false) String parameter2,
BindingResult result, HttpServletRequest request)
throws ParseException {
LONG CODE and SAME LONG CODE with a minor difference
}
if @RequestParam(required = true)
then you must pass parameter1,parameter2
Use BindingResult and request them based on your conditions.
The Other way
@RequestMapping(value = "/books", method = RequestMethod.GET)
public ModelAndView listBooks(@ModelAttribute("booksFilter") BooksFilter filter,
two @RequestParam parameters, HttpServletRequest request) throws ParseException {
myMethod();
}
@RequestMapping(value = "/books", method = RequestMethod.POST)
public ModelAndView listBooksPOST(@ModelAttribute("booksFilter") BooksFilter filter,
BindingResult result) throws ParseException {
myMethod();
do here your minor difference
}
private returntype myMethod(){
LONG CODE
}
