为您的 Action定义一个input结果，指向该success结果的同一个 JSP。

在 JSP 中，检查 actionErrors 或 fieldErrors，如果有则打印它们，例如：

<s:if test="actionErrors != null && actionErrors.size > 0">
    <div class="feed_ko">
        <s:actionerror escape="false" />
    </div>
</s:if>
<s:if test="fieldErrors != null && fieldErrors.size > 0">
    <div class="feed_ko">
        <s:fielderror />
    </div>
</s:if>
