Question

我已将我的struts应用程序升级到版本2.3.30和apache-tiles 2.2.2并且我面临s：action标记和tile结果的问题。它进入递归循环并抛出StackOverflowError，如下所示。

我也能在展示应用程序中重现这个问题，我已经概述了tiles.xml，struts-tile.xml和layout.jsp，如下所示。

it throws java.lang.StackOverflowError: null

        at org.apache.catalina.core.ApplicationHttpRequest.getAttribute(ApplicationHttpRequest.java:230)

    at org.apache.jsp.WEB_002dINF.tiles.layout_jsp._jspService(layout_jsp.java:109)

这是我的用法，

tiles.xml

<definition name="showcase.index" template="/WEB-INF/tiles/layout.jsp">
    <put-attribute name="title" value="Tiles Showcase"/>
    <put-attribute name="header" value="/WEB-INF/tiles/header.jsp"/>
    <put-attribute name="body" value="/WEB-INF/tiles/body.jsp"/>
</definition>

<definition name="showcase.index.actionResult" template="/WEB-INF/tiles/actionTileResult.jsp">
    <put-attribute name="title" value="Tiles Result from action"/>
</definition>

支柱-tiles.xml

    <action name="index">
        <result type="tiles">showcase.index</result>
        <result name="success" type="tiles">showcase.index</result>
    </action>

    <action name="myTestAction">
        <result type="tiles">showcase.index.actionResult</result>
        <result name="success" type="tiles">showcase.index.actionResult</result>
    </action>

Layout.jsp

<html>
    <head><title>Struts2 Showcase - <tiles:getAsString name="title"/></title></head>
<body>
    <tiles:insertAttribute name="header"/>
    <tiles:insertAttribute name="body"/>
    <p>Notice that this is a layout made in JSP</p>
    <!-- This action causing stackoverflow error --> 
**  <s:action name="myTestAction" namespace="/tiles" executeResult="true" /> **
</body>
</html>

actionTileResult.jsp

<tiles:importAttribute name="title" scope="request"/>
<html>
    <head><title>Action tile result <tiles:getAsString name="title"/></title></head>
<body>
    <p>Notice that this is a  jsp</p>
</body>
</html>

请告诉我任何遇到类似问题的人及其任何解决方案。
