Spring MVC验证问题

[djy1135]

我用spring 调用common的validator进行页面验证的时候,如果是String型的,则验证正常.如果是Integer型的就出错?
Failed to convert property value of type [java.lang.String] to required type [java.lang.Integer] for property age; nested exception is java.lang.NumberFormatException: For input string: ""

后来我在Controller中加了一段:
protected void initBinder(HttpServletRequest request,ServletRequestDataBinder binder) throws Exception {
binder.registerCustomEditor(Integer.class,new CustomNumberEditor(Integer.class,null,true));
}

然后,刚才始进入页面时不出错了,即不输入数据的时候不出错,一旦输入了字符,则就出现如下错误:
Failed to convert property value of type [java.lang.String] to required type [int] for property age; nested exception is java.lang.NumberFormatException: For input string: "ff"



我在validation.xml中的配置如下:
<form name="user">
<field property="name"
depends="required">

<arg0 key="姓名"/>
</field>
<field property="age"
depends="required,integer">

<arg0 key="年龄"/>
</field>
<field property="email"
depends="required,email">

<arg0 key="姓名"/>
</field>

</form>

另外在user.java中
age的类型为 integer


请高手指点,谢谢!!!

没人用过吗?

这个问题我回答过,取数据时把integer型字段转化成string型,表单里age按字串型处理就是了

恩,在得到和插入数据的时候把类型转换一下就可以了

还有没有其它答案???
上面二位的回答,貌似不太理想!
User类是一个pojo,我们用了 hibernate

问题终于解决了:
Have the customized typeMismatch message in your message properties
file that Spring load as messageResource.

Example:
# For generic error message on type mismatch Date
typeMismatch.java.util.Date={0} is an invalid date.

# For specific error message on perticular form field
# (e.g. startDt is a form field name)
typeMismatch.startDt=Start Date is an invalid date.
