Struts2验证

Question

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

我在问这个验证xml不会在我的情况下被调用。

Answer 1

希望您已经创建了适当的规则文件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。另外，如果您没有配置默认拦截器，请在Struts.xml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>

请参阅有关验证框架的更多详细信息，只是通过它，并检查其是否正确
