以下是我在这里发布的答案。OGNL and wildcards working in tiles definitions with struts2-tiles-plugin?

如果你知道答案，如果你告诉我如何使用共济会。如果不超过我接受的答案，如果你解决了我的问题，使代码工作。

一切都一样，但是

结论

如果您将它与Glassfish一起使用，用代码进行测试是很好的，但是。

经过大量的测试和检查，问题在于嵌入式tomcat7实例无法处理上述web.xml配置和产生的错误。下面是pom.xml插件，如果运行tomcat7 7: run将生成错误。不知道有什么问题。

Note：已经测试了以下功能( tiles 2.2.2和共济会用户的struts2)。由于时间限制，此解决方案适用于struts2 2.3.1.2和支柱2-tiles-plugin-2.3.1.2，而不是更高的版本。试了2.3.4.1，有东西坏了。

设置以下内容：OGNL and wildcards working in tiles definitions with struts2-tiles-plugin?

添加了对tiles的共济会者支持：

：tiles-freemarker，Group：org.apache.tiles，Version：2.2.2

将前面示例中的测试扩展为将共济会者标题合并到演示中： Add /WEB-INF/content/tiles/test.ftl，其中包含：

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

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

<?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it

我的应用程序上下文是http://localhost:8080/Struts2Tiles2_2_2Example/附加的package/bla，我们有http://localhost:8080/Struts2Tiles2_2_2Example/package/bla，我们将看到一个由速度呈现到视图中的文本字段，标题栏将表示'bla‘。
