我对 Spring 还很陌生,在我的 Spring mvc 应用程序中访问我的资源时遇到了问题。我试过谷歌并使用堆栈溢出来找到答案(这些都没有帮助我可能的解决方案 1,或可能的解决方案,可能的解决方案 3,弹簧框架)但我发现没有一个解决了我的问题或提高了我对问题(可能只是因为我不太了解提到的解决方案)。
我已设法将我的 css 文件嵌入到网页中,但使用以下代码:
<%@include file="css/style.css" %>
但由于显而易见的原因,我无法以这种方式使用 URL 访问它。我也尝试在我的 web.xml 文件中使用以下内容,但它没有效果,我承认我并不真正理解这种情况下的映射,所以这可能是一个问题
<mvc:annotation-driven />
<mvc:resources mapping="/images/**" location="/images/" />
<mvc:resources mapping="/css/**" location="/css/" />
我也尝试过分别使用以下各项:
<img src="<%=request.getContextPath()%>/images/logo.jpg"/>
<img src="<%=request.getContextPath()%>/src/main/resources/images/logo.jpg"/>
这是我的项目布局:
这是我的 web.xml:
<web-app id="WebApp_ID" version="2.4"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<servlet-mapping>

<url-pattern>/</url-pattern>

这是我的 myServlet-servlet.xml:

如果我可以像访问我的 jsp 页面(即通过 URL)一样从 webapp/WEB-INF/pages 中访问图像和 css 文件夹以及这些文件夹的内容,我会很高兴,但理想情况下我想了解我应该如何正确执行此操作,即我应该映射哪个文件夹(src\main\resources 或 src\main\webapp\WEB-INF\some_resource_folder)以及我应该如何映射它。
如果需要更多信息,我很乐意提供。
