在Struts2中，Validator表达式对我不起作用

Question

我想配置验证表达式类型以验证四个字段的总和不超过100

<validator type="expression" short-circuit="true">
    <param name="expression">
     (employee.analysis + employee.development + employee.test + employee.maintenance) gt 100
    </param>
    <message key="validations.error.total"/>
</validator>

但上述解决方案并不起作用

我也试过这个：

<validator type="expression" short-circuit="true">
    <param name="expression">
     <![CDATA[(employee.analysis + employee.development + employee.test + employee.maintenance) > 100 ]]>
    </param>
    <message key="validations.error.total"/>
</validator>

Answer 1

解决方案就是：

<validator type="expression" short-circuit="true">
    <param name="expression">
     <![CDATA[(employee.analysis + employee.development + employee.test + employee.maintenance) <= 100 ]]>
    </param>
    <message key="validations.error.total"/>
</validator>
