Failed to convert property value of type [java.lang.String] to required type [java.util.Date] for pr

在springmvc中如果表单属性的类型是日期型时，从页面绑定字符串数据会出错 
Failed to convert property value of type [java.lang.String] to required type [java.util.Date] for property 'expert.birthdate'; nested exception is java.lang.IllegalArgumentException: Cannot convert value of type [java.lang.String] to required type [java.util.Date] for property 'birthdate': no matching editors or conversion strategy found 

解决方法 
1.控制器继承 extends SimpleFormController 

2.重写initBinder方法 

1. @InitBinder  
2. protected void initBinder(HttpServletRequest request,  
3.             ServletRequestDataBinder binder) throws Exception {   
4.       DateFormat fmt = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");  
5.       CustomDateEditor dateEditor = new CustomDateEditor(fmt, true);  
6.       binder.registerCustomEditor(Date.class, dateEditor);  
7.       super.initBinder(request, binder);   
8. }  

注意SimpleDateFormat日期格式与页面日期格式要一致！
