时间类型传到后台controller

需要在controller里面为日期数据的从jsp传送到后台做的准备

@InitBinder 
public void initBinder(WebDataBinder binder) throws Exception {
             //  时间格式为yyyy-MM-dd类型需要的绑定
     DateFormat df = new SimpleDateFormat("yyyy-MM-dd");
     binder.registerCustomEditor(Date.class, null, new CustomDateEditor(df, 
                true));
             // 时间格式为HH:mm:ss类型需要的绑定   这里我们自己定义一个CustomTimeEditor类 用来接收需要传过来的类型
             SimpleDateFormat tf = new SimpleDateFormat("HH:mm:ss");
     binder.registerCustomEditor(Time.class, null, new CustomTimeEditor(tf, 
                true));
   }

* part may still allow for a shorter year part, so consider this as just
* one more assertion that gets you closer to the intended date format.
