我使用 spring roo 来生成 web 项目。在我使用 设置 web mvc 后web mvc setup，webapp 文件夹的结构如下：

.../webapp/
      |
      |_images
      |_styles
      |_WEB-INF 
           |
           |_classes
           |_i18n
           |_spring
           |_layouts
           |_tags
           |  |_form
           |  |_menu
           |  |_util
           |
           |_views
           |_web.xml

我把 layouts, images, style 和 tags 文件夹放到了 views 文件夹中（因为我有这个项目的其他视图，我不想把它们弄乱），我在 views.xml 中更改了相关路径，以及所有*.jspx 文件中的标记路径。这是更改后文件的样子。

文件结构

.../webapp/
      |
      |_WEB-INF 
           |
           |_classes
           |_i18n
           |_spring
           |
           |_views
           |    |_images
           |    |_layouts
           |    |_styles
           |    |_tags
           |       |_form
           |       |_menu
           |       |_util
           |_web.xml

web-mvc.xml

<!-- selects a static view for rendering without the need for an explicit controller -->
    <mvc:view-controller path="/login"/>
    <mvc:view-controller path="/logout"/>
    <mvc:view-controller path="/" view-name="index"/>
    <mvc:view-controller path="/uncaughtException"/>

            </div>
        </div>
    </body>
</html>

索引.jspx

<div xmlns:spring="http://www.springframework.org/tags" xmlns:util="urn:jsptagdir:/WEB-INF/views/tags/util" xmlns:jsp="http://java.sun.com/JSP/Page" version="2.0">

  <util:panel id="title" title="${title}">
    <h3>

    </h3>
    <p>
      <spring:message code="welcome_text" />
    </p>
  </util:panel>
</div>

我只是忽略了其他 jspx 文件，如页眉、页脚等，因为我只是更改了该文件的一部分，即“ xmlns:util="urn:jsptagdir:/WEB-INF/tags/util"”，并将其更改为“ xmlns:util="urn:jsptagdir:/WEB-INF/views/tags/util"”。

现在我运行mvn clean install，mvn clean tomcat:run项目可以构建并部署到tomcat服务器中，没有任何错误。当我在浏览器中访问主页时，我总是收到以下错误。

我用一整天的时间在谷歌上寻找解决方案，但我一无所获。如果我保留 spring roo 生成的默认结构，一切都很好。所以我确定我在更改配置文件时一定做错了什么，但我就是找不到。

有没有人可以帮我解决这个问题？

非常感谢您！

不要与你的工具抗争。最初的组织并不完全是 Roo 特定的，而是由 Java Web 标准定义的。

  1. WEB-INF 内部的任何内容都不能直接向公众开放，图像和样式应保留在外部。
  2. 标记文件在 Java Web 标准中也有特定的位置。
  3. 布局由 Apache Tiles 处理，所以我不确定它们的位置是否受到限制。
