Question

我有一个带有一些文本字段的Jsp，这些是使用Hibernate验证注释（动作中的@Valid或@NotNull）验证，除了一个（输入图像文件），它使用默认的Struts2验证进行验证（使用ActionName-validation.xml）。我想在提交的表单无效时重定向到另一个操作（当textfields为null时），并且我想存储字段错误。

我试过这个：

<interceptors>
    <interceptor name="SessionCheckInterceptor" class="util.SessionCheckInterceptor"/>
        <interceptor-stack name="mySessionValidationStack">              
            <interceptor-ref name="defaultStackHibernate" />
            <interceptor-ref name="SessionCheckInterceptor" />
        </interceptor-stack>      
</interceptors> 

<default-interceptor-ref name="mySessionValidationStack"/> 

<action name="insert" class="actions.InsertAction" >       
    <interceptor-ref name="mySessionValidationStack">
        <param name="fileUpload.allowedTypes">image/png</param>
    </interceptor-ref> 
    <interceptor-ref name="store">
        <param name="operationMode">STORE</param>
    </interceptor-ref>
    <interceptor-ref name="defaultStack" />
    <result name="success" type="tiles" >baseLayout</result>
    <result name="error" type="redirectAction" >
        <param name="actionName">showinsertform</param>
    </result>
    <result name="input" type="redirectAction" >
        <param name="actionName">showinsertform</param>
    </result>
</action>

<action name="showinsertform" class="actions.ShowInsertFormAction" > 
    <interceptor-ref name="mySessionValidationStack" />
    <interceptor-ref name="store">
        <param name="operationMode">RETRIEVE</param>
    </interceptor-ref>
    <result name="success" type="tiles" >insert</result>
    <result name="error" type="tiles" >baseLayout</result>
</action>

但是当我对表单进行求和时，重定向成功而没有显示我的字段错误消息。也许我设置错误的拦截器？使用hibernate我需要覆盖一些东西？如果我尝试在操作中设置手动错误消息（使用addActionError），它们可以工作！是否可以将hibernate错误字段消息存储在会话中？

Hibernate插件struts-plugin.xml这里你使用的是 defaultStackHibernate ，它不包括在struts-default.xml中定义的商店拦截器，你应该在使用它之前将商店拦截器包含到你的自定义拦截器堆栈中
