在使用spring mvc中,绑定页面传递时间字符串数据给Date类型是出错：

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

解决方法一：

1.使对应Controller控制器继承 extends SimpleFormController  
2.重写initBinder方法

protected void initBinder(HttpServletRequest request, ServletRequestDataBinder binder){  
            　　SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd");  
               dateFormat.setLenient(false);  
               binder.registerCustomEditor(Date.class, new CustomDateEditor(dateFormat, false));          
        }

注意SimpleDateFormat日期格式与页面日期格式要一致！

解决方法二：

Spring3.0以上的SimpleFormController 已经过时了,最新方式是使用@InitBinder注解的方式

在对应的Controller控制器中

@InitBinder
        protected void init(HttpServletRequest request, ServletRequestDataBinder binder) {
            SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");
            dateFormat.setLenient(false);
            binder.registerCustomEditor(Date.class, new CustomDateEditor(dateFormat, false));
        }
