CSS和JavaScript文件在Maven Web应用程序项目中的位置？

我正在切换到我的Spring Web应用程序项目使用Maven，我遇到了一个简单的问题。 我不知道在哪里把CSS和JS文件放在新的项目结构中。

传统的Web应用结构

在传统的Java Web应用程序结构（在Eclipse中，创build为Dynamic Web Project），我将CSS，Javascript和Images文件放在以下结构 

WebContent |__css/myStyles.css |__js/myjs.js |__images/myImage.gif |__WEB-INF

然后在我的jsp，如果我想引用一个CSS文件，我做如下： 

 <link rel="stylesheet" href="<%=request.getContextPath()%>/css/myStyles.css">

这工作正常。

Maven Web应用程序结构

在一个Maven项目中，我把这些css文件放在这些位置：

第一次尝试

在与WEB-INF相同的webapp文件夹下，就像传统的dynamicweb项目一样。 但是当我做了以下 

 mvn clean tomcat:run

我从Spring框架中得到以下错误： 

 org.springframework.web.servlet.PageNotFound - No mapping found for HTTP request with URI [/appname/css/myStyles.css] in DispatcherServlet

第二次尝试

放置我的CSS文件夹下src /主要/资源但是，当我做到以下几点： 

 mvn clean tomcat:run

我从Spring框架中得到以下错误： 

 org.springframework.web.servlet.PageNotFound - No mapping found for HTTP request with URI [/appname/css/myStyles.css] in DispatcherServlet

第三次尝试

放置我的CSS文件夹src / main / resources

结果：同上

我相信这是简单的，但我卡住了，也许我忽略了一些东西。 提前致谢

更新 ：添加pom.xml，看看它是否可以帮助解决问题：

更新：添加Web.xml 

 <?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <!-- The definition of the Root Spring Container shared by all Servlets and Filters --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/spring/root-context.xml classpath*:META-INF/spring/applicationContext*.xml </param-value> </context-param> <!-- Creates the Spring Container shared by all Servlets and Filters --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- Processes application requests --> <servlet> <servlet-name>appServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/spring/appServlet/servlet-context.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>appServlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping>

所以如果你的DispatcherServletconfiguration成像REST那样的URL模式，那么css文件就会在src / main / webapp / resources下

只是为了澄清这是我不得不做的：

  1. 确保在你的servlet-context.xml中有如下所示： 

     <resources mapping="/resources/**" location="/resources/" />

  2. 如果在名为resources的 webapps下不存在，则创build一个文件夹

  3. 把你的css文件夹和css文件放在一起

  4. 引用我的css文件如下： 

     <link rel="stylesheet" href="<%=request.getContextPath()%>/resources/css/960.css"/>

我在一个Maven项目中遇到了同样的问题。 我的问题似乎没有很好的答案。 所以我做了一个简单的实验，它完美的工作。

这是一个简单的maven项目，我有以下的目录结构：（不相关的目录不显示） 

 ───src
    └───main
        ├───java
        ├───resources
        └───webapp
            ├───javascript
            │├───test.js
            │├───example.js
            │└───jquery-library.js
            ├───WEB-INF
            │└───web.xml
            └───example.jsp

我的JSP页面可以简单地引用我的JavaScript库 

 <script src=javascript/jquery-library.js></script>

不需要任何特殊的configuration。

org.springframework.web.servlet.PageNotFound – 在DispatcherServlet中没有find具有URI [/appname/css/myStyles.css]的HTTP请求的映射

这表示web.xml / spring上下文文件的configuration问题。 DispatcherServlet不应该处理一个css资源的请求。

如果这不能解决问题，您可能需要发布web.xml和spring上下文文件的相关代码片段。
