【问题描述】：

我正在关注此处发布的答案。 OGNL and wildcards working in tiles definitions with struts2-tiles-plugin?

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，我什至接受答案。

一切都一样，但是

Struts2 & Tiles plugin - 2.3.4.1

结论

如果您将它与 Glassfish 一起使用，则代码测试工作正常但是

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 插件，如果运行tomcat7:run 会产生错误。不知道是什么问题。

                <groupId>org.apache.tomcat.maven</groupId>
                <artifactId>tomcat7-maven-plugin</artifactId>

                </configuration>
            </plugin>

【问题讨论】：

我刚刚升级了我的示例应用程序（用于创建您链接到的示例）...我不确定发生了什么变化，我现在不知道如何修复它.
你把监听器放在 web.xml 中了吗？？
@ashish-gupta，是的。看到我的问题在最后添加了我的 web.xml。
@quaternion，现在我被卡住了 :( 。我想将图块与 freemarker 集成为我的目标。
最快的解决方案是恢复到 2.3.1.2（struts2-core 和 struts2-tiles-plugin），因为升级后出现问题。哦，向 struts2-tiles-plugin 维护者抱怨！

标签： struts2 tiles

【解决方案1】：

注意：以下内容已经过测试（struts2 与 tile 2.2.2 和 freemarker）。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 and wildcards working in tiles definitions with struts2-tiles-plugin?

为图块添加 freemarker 支持：

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

扩展上一个示例的测试，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"/>

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

<?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>

测试一下：

我的应用上下文是http://localhost:8080/Struts2Tiles2_2_2Example/ 附加package/bla 我们有http://localhost:8080/Struts2Tiles2_2_2Example/package/bla，我们将看到一个由velocity 渲染的文本字段并入视图，标题栏会显示“bla”。

【讨论】：

更改了 struts2 版本，但仍然是同样的错误。你能添加你的 pom.xml 看看有什么问题吗？您如何看待这种 Struts2+Tiles+FreeMarker 集成的解决方案？ sooin01.tistory.com/entry/…
我没有时间阅读它，但他们的 web.xml 看起来比必要的复杂。我会提供 pom 和 web.xml。
我只是看了一眼示例，但它们也使用了切片通配符，该方法不允许评估切片内的 ognl 表达式。它确实显示了集成，但它并没有像我们希望的那样集成。额外级别的功能意味着表达式需要加上前缀才能理解它们是如何计算的，即。 : WILDCARD:package/* 和 OGNL:greeting
我已经尽力了。跟随您发布的任何内容，但仍然收到有问题的错误。我已在问题中添加了我当前的项目信息并将其标记为已编辑版本。请看看你能不能帮忙。
将您的电子邮件放在您的个人资料中，我会通过电子邮件将项目发送给您，直到今晚我才有机会（可能从现在开始 7 小时）。作为交换，如果您能找出阻碍成功的问题，那么我们就可以清楚地说明问题，那就太好了 =)
