1,<spring:bind>是spring2.0以前的寫法。
2,public ModelAndView login(HttpServletRequest request,
?? ??? ??? ?HttpServletResponse response,HttpSession session,User user)
? public ModelAndView login(HttpServletRequest request,
?? ??? ??? ?HttpServletResponse response,User user)
MultiActionController自動把最后一個參數當作Command對象。
也可以覆蓋protected Object newCommandObject(Class clazz)方法，但這樣每個 Controller的Command對象就是同一個iele，
同時要改為
public ModelAndView login(HttpServletRequest request,
?? ??? ??? ?HttpServletResponse response,Object command)再對command造型
?? ??? ??? ?
3，重定向寫法
return new ModelAndView("redirect:/system/user.do?do=addUserForm");

4，有2個JsonView的，或者更適合Ajax，當然自己寫一個JsonView都很簡單
1) json-lib-ext-spring
http://sourceforge.net/projects/json-lib/files/
2) spring json view

5, 綁定的基本寫法
ServletRequestDataBinder binder = new ServletRequestDataBinder(obj);
??? ??? SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
??? ??? binder.registerCustomEditor(Date.class, new CustomDateEditor(
??? ??? ??? ??? dateFormat, true));
??? ??? binder.setDisallowedFields(new String[]{"endtime"});
??? ??? binder.bind(request);
