spring mvc出现 Failed to convert property value of type 'java.lang.String' to required type'java.util~

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

复制代码

    @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));
    }
