Answer 1

您可以在一个变量中设置值并将该变量传递给标签 并将其发送到组件jsp。

<s:set var="po" value="%{snPurchaseOrder}"></s:set>
        <s:push value="po">
        <jsp:include page="/template/xhtml/snsales/poComponentInfoNew.jsp">
    </jsp:include>
</s:push>

在子jsp中，您可以通过#变量名称访问，例如#po。

Answer 2

由

s:component

标签引起的问题，该标签用于渲染自定义 UI 小部件的模板。

它的工作原理与

s:include

标签相同，将内容写入输出流。它使用

FastByteArrayOutputStream

写入内容。它有一个大小为

8192

的缓冲区。该缓冲区已溢出。

这可能是一个错误，已在较新版本的 Struts2 框架中修复。
