Spring JSTL标签不起作用

标签： exception spring-mvc spring-roo taglib jspx

我使用spring roo来生成web项目。在使用web mvc setup设置web mvc后，webapp文件夹具有以下结构：

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

我将布局，图片，样式和标签文件夹放入views文件夹中（因为我有这个项目的其他视图，我不想搞砸它们），我更改了views.xml中的相关路径，以及* .jspx文件中的所有标记路径。以下是文件发生变化后的样子。

文件结构

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

网络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"/>

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

我只是忽略了其他jspx文件，比如页眉，页脚等，因为我刚刚更改了那部分文件，即“xmlns:util="urn:jsptagdir:/WEB-INF/tags/util"”，我将其更改为“xmlns:util="urn:jsptagdir:/WEB-INF/views/tags/util"” ”

现在我运行mvn clean install和mvn clean tomcat:run，可以构建项目并将其部署到tomcat服务器中而不会出现任何错误。当我在浏览器中访问主页时，我总是会收到以下错误。

我用我整天的时间来谷歌寻求解决方案，但我什么都没得到。如果我保留spring roo生成的默认结构，一切都很好。所以我确信在更改配置文件时我必须做错事，但我找不到它。

有没有人可以帮我解决这个问题？

提前非常感谢你！

不要打击你的工具。原始组织并不完全是Roo特定的，但它是由Java Web标准定义的。

  1. WEB-INF内部的任何内容都不能直接访问公众，图像和样式应保留在外面。
  2. 标记文件在Java Web标准中也有一个特定的位置。
  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。
