Struts2验证

Question

在Struts2中，我们是否可以在Action类中同时实现验证xml (ActionClass- method -validation.xml)和验证方法。

我问的是，在我的情况下，验证xml不会被调用。

Answer 1

希望您已经创建了正确的规则文件actionname-validation.xml (注意- actionname区分大小写)，并将其保存在与Action类相同的包中。

此外，如果您没有配置默认拦截器，请在Struts.xml中的该特定操作标签中添加验证拦截器。

<action name="welcome"  class="com.abc.web.WelcomeAction">
<interceptor-ref name="validation" />
<result name="success" >hello.jsp</result>
</action>

有关验证框架的更多详细信息，请参阅http://struts.apache.org/2.0.14/docs/validation.html和http://java.dzone.com/articles/struts2-tutorial-part-37

只需检查一遍，检查是否正确
