SpringMVC 限定某个业务控制方法，只允许GET或POST请求方式访问

@Controller@RequestMapping(value="/user")public class UserAction{    @RequestMapping(value="/add",method=RequestMethod.POST)    public String add(Model model,int id,String name,double sal) throws Exception{        System.out.println("HelloAction::add()::POST");        System.out.println(id + ":" + name + ":" + sal);        model.addAttribute("message","增加用户");        return "/success.jsp";    }   }

method=RequestMethod.POST
如果不书写method=RequestMethod.POST的话，GET和POST请求都支持
