我有一个带有一些文本字段的 Jsp，它们使用 Hibernate 验证注释（操作中的 @Valid 或 @NotNull）进行验证，除了一个（输入图像文件）使用默认的 Struts2 验证（使用 ActionName-validation.xml）进行验证。当提交的表单无效时（当文本字段为空时），我想重定向到另一个操作，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>

但是当我提交表单时，重定向成功而没有显示字段错误消息。也许我设置错误的拦截器？使用休眠我需要覆盖一些东西？如果我尝试在操作中手动设置错误消息（使用 addActionError），它们会起作用！会不会是休眠错误字段消息没有存储在会话中？

Hibernate 插件 struts-plugin.xml 在这里您使用的是defaultStackHibernate，它不包括在struts-default.xml中定义的存储拦截器，您应该在使用它之前将存储拦截器包含到您的自定义拦截器堆栈中。
