struts中validator验证框架minLength的问题

[yuanjian0211]

validation.xml中配置的如下：
<field
property="tel"
depends="long,minlength">
<arg0 key="npis.tel" />
<arg1 name="minlength" key="${var:minlength}" resource="false"/>
<var>
<var-name>minlength</var-name>
<var-value>7</var-value>
</var>
</field>

有个输入框tel,这个输入框没有用required验证,我希望在不为空的时候才执行minLength验证，但是目前却是即使为空，也执行了minLength验证，如何设定只有在不为空的时候才执行minLength验证呢？－－－请指点

validator-rules.xml
depends="required" 如果没通过required验证不会进行minlength验证



<validator name="minlength"
classname="org.apache.struts.validator.FieldChecks"
method="validateMinLength"
methodParams="java.lang.Object,
org.apache.commons.validator.ValidatorAction,
org.apache.commons.validator.Field,
org.apache.struts.action.ActionMessages,
javax.servlet.http.HttpServletRequest"
depends="required"
msg="errors.minlength"
jsFunction="org.apache.commons.validator.javascript.validateMinLength"/>
