struts验证框不能进行验证

Question

能不能帮忙解决一下，现在我调试好了，可是validation.xml里面的参数出不来，比如
<arg name="minlength" key="${var:minlength}" resource="false" position="1"/>
在消息里面没有这个参数！

Answer 1

是不是你input 的路径的问题呢

Answer 2

没看出你的有什么问题：
validation.xml
<form-validation >
  <formset>
    <form name="loginForm">
      <field property="username" depends="required,mask">
        <arg0 key="label.username"/>
        <var>
          <var-name>mask</var-name>
          <var-value>^[a-zA-Z]*$</var-value>
        </var>
      </field>
    </form>
  </formset>
</form-validation>

struts-config.xml
<struts-config>
  <form-beans>
    <form-bean name="loginForm" type="validate4.loginForm">
      <form-property name="password" type="java.lang.String" />
      <form-property name="username" type="java.lang.String" />
    </form-bean>
  </form-beans>
  <action-mappings>
    <action name="loginForm" path="/loginAction" scope="session" type="validate4.LoginAction" validate="true"  input="/login.jsp"/>
  </action-mappings>
  <plug-in className="org.apache.struts.validator.ValidatorPlugIn">
