大家好，我正在尝试在表单上使用验证，并且我做了示例中的所有工作，并且多次搜索以寻找解决方案，但不幸的是我无法解决问题。
我的问题是：当我单击带有空字段的提交按钮时，它向数据库注册为空并且验证不起作用!!!!!!!!!!!!
我正在使用struts2 tomcat7 jdk7 spring4 hibernate3和sitemesh 2.4.2
有人可以帮我吗struts.xml：

另一件事是BankInfoAction-validation.xml和BankInfoAction.java在同一目录中
最佳答案
你应该用
<field name="bankName">
<field-validator type="requiredstring">
<message key="errors.required"/>
</field-validator>
</field>
因为此字段已填充。
modelDriven拦截器将模型放在值堆栈的顶部。因此，您不必担心设置值。
