我正在关注此处发布的答案。OGNL 和通配符在使用 struts2-tiles-plugin 的瓷砖定义中工作？

如果您知道答案，如果您告诉我如何使用 freemarker 将不胜感激。如果您解决我的问题以使代码正常工作，我什至不接受答案。

一切都一样，但

Struts2 & Tiles plugin - 2.3.4.1

结论

如果您将其与 Glassfish 一起使用，则使用代码进行测试可以正常工作但

经过大量测试和检查，问题在于嵌入式 tomcat7 实例无法使用上述 web.xml 配置并生成错误。下面是pom.xml如果运行 tomcat7:run 将产生错误的插件。不确定是什么问题。

注意：以下内容已经过测试（带有 tile 2.2.2 和 freemarker 的 struts2）。由于时间限制，此解决方案适用于 struts2 2.3.1.2 和 struts2-tiles-plugin-2.3.1.2，但不适用于更高版本。尝试了 2.3.4.1，但有些东西坏了。

设置以下内容：OGNL 和通配符在使用 struts2-tiles-plugin 的图块定义中工作？

添加对图块的 freemarker 支持：

工件：tiles-freemarker， 组：org.apache.tiles， 版本：2.2.2

扩展上一个示例的测试以将 freemarker 标题合并到演示中： 添加/WEB-INF/content/tiles/test.ftl其中包含：

<#assign s=JspTaglibs["/struts-tags"] /> 
<@s.textfield name="test"/>

<put-attribute name="body" value="/WEB-INF/content/tiles/test.ftl"/>定义下的tiles.xml 中添加了一行WILDCARD:package/*。

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE tiles-definitions PUBLIC
       "-//Apache Software Foundation//DTD Tiles Configuration 2.1//EN"
       "http://tiles.apache.org/dtds/tiles-config_2_1.dtd">
<tiles-definitions>
    <definition name="baseLayout" template="/WEB-INF/content/tiles/template.jsp">
        <put-attribute name="title" value="Default Title"/>
        <put-attribute name="header" value="/WEB-INF/content/tiles/header.jsp"/>
        <put-attribute name="body" value="/WEB-INF/content/tiles/body.jsp"/>
        <put-attribute name="footer" value="/WEB-INF/content/tiles/footer.jsp"/>
        <put-attribute name="variable"  expression="OGNL:greeting"/>
    </definition>
    <definition name="test" extends="baseLayout">
        <put-attribute name="title" value="Test Title"/>
    </definition>
    <definition name="WILDCARD:package/*" extends="baseLayout">
        <put-attribute name="title" value="{1}" type="string"/>
        <put-attribute name="body" value="/WEB-INF/content/tiles/test.ftl"/>
    </definition>
    <definition name="" extends="baseLayout">
    </definition>
</tiles-definitions>

测试它：

我的应用程序上下文是http://localhost:8080/Struts2Tiles2_2_2Example/附加的，package/bla我们http://localhost:8080/Struts2Tiles2_2_2Example/package/bla将看到一个由速度渲染的文本字段并入视图，标题栏会显示“bla”。
