在Spring中结合GET和POST请求方法

@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}

如果这样，

@RequestParam(required = true)

使用BindingResult并根据您的条件请求它们。

另一种方法

@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}
