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

@InitBinder

protected void initBinder(HttpServletRequest request,

ServletRequestDataBinder binder) throws Exception {

DateFormat fmt = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

CustomDateEditor dateEditor = new CustomDateEditor(fmt, true);

binder.registerCustomEditor(Date.class, dateEditor);

super.initBinder(request, binder);

}

注意SimpleDateFormat日期格式与页面日期格式要一致！
