struts2.0 验证框架

Question

struts2.0 自带的验证框架能不能验证输入表单中 两次输入的密码 是否一致呢？ 如果可以，怎么实现啊？

Answer 1

<field name="password">
<field-validator type="requiredstring">
<param name="trim">true</param>
<message>密码不能为空</message>
</field-validator>

<field-validator type="stringlength">
<param name="minLength">5</param>
<param name="maxLength">16</param>
<message>密码必须在${minLength} 到 ${maxLength}之间</message>
</field-validator>
</field><!-- 验证重复密码 -->
<field name="repassword">
<field-validator type="requiredstring">
<param name="trim">true</param>
<message>重复密码不能为空</message>
</field-validator>

<field-validator type="fieldexpression">
            <param name="expression">password == repassword</param>
            <message>两次输入的密码不一致</message>
        </field-validator>
</field>
