CSS和JavaScript文件在Maven Web应用程序项目中的位置是什么？

时间：2011-10-20 13:48:42

标签： css maven pom.xml

我转而使用Maven作为我的Spring网络应用程序项目，我遇到了一个简单的问题。我不确定将CSS和JS文件放在新项目结构中的哪个位置。

传统的网络应用结构

在传统的Java Web应用程序结构中（在Eclipse中，创建为动态Web项目）我将CSS，Javascript和Images文件放在以下结构中

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

然后在我的jsp中，如果我想引用一个CSS文件，我按如下方式执行：

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

这很好用。

Maven Web App结构

在Maven项目中，我已将css文件放在以下位置：

第一次尝试

与WEB-INF处于同一级别的 webapp 文件夹下，就像在传统的动态网络项目中一样。但是，当我做以下

mvn clean tomcat:run

我从Spring Framework中收到以下错误：

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

第二次尝试

将我的css文件夹放在 src / main / resources 下但是当我执行以下操作时：

mvn clean tomcat:run

我从Spring Framework中收到以下错误：

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：与上述相同

我确信这很简单，但我被困住了，也许我忽视了一些事情。提前致谢

更新：添加pom.xml以查看它是否可以帮助解决问题：

因此，如果您将DispatcherServlet配置为REST模式（如 / ），则css文件将位于 src / main / webapp / resources

下

只是为了澄清这是我必须要做的事情：

  1. 确保您的 servlet-context.xml 具有以下内容：

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

  2. 如果在名为资源的

    3. 的webapps下尚不存在，请创建一个文件夹

  3. 将 css 文件夹与css文件一起放在

  4. 引用我的css文件如下：

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

答案 1 :(得分：14)

我在maven项目中遇到了同样的问题。对我的问题似乎没有好的答案。所以我做了一个简单的实验，它运作得很好。

这是一个简单的maven项目，我有以下目录结构： （不显示不相关的目录）

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

我的JSP页面可以简单地称为我的javascript库

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

无需任何特殊配置。

答案 2 :(得分：4)

  

org.springframework.web.servlet.PageNotFound - 找不到映射   DispatcherServlet中带有URI [/appname/css/myStyles.css]的HTTP请求

这表示您的web.xml / spring上下文文件存在配置问题。 DispatcherServlet不应处理css资源的请求。

如果这无法解决问题，您可能需要发布web.xml和spring上下文文件的相关摘要。

答案 3 :(得分：0)

来自this answer，来自@Mario-这取决于包装。

如果您的Maven项目是WAR，请将其放在webapp目录中。您可以选择在webapp目录（即webapp/css/main.css）中使用子文件夹，也可以将文件直接放在webapp目录（即webapp/main.css）中。

如果您使用的是JAR，请放在resources目录中。正如Viratoro @上面提到的，映射资源目录需要一些配置。

答案 4 :(得分：0)

我为此问题找到的最佳解决方案是使用Java配置

@Configuration
 @EnableWebMvc
 public class WebAppConfig implements WebMvcConfigurer {
     
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        
    registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
    }
}
