css - 在动态 Web 项目中访问 c​​ss、js 文件的问题

Question

我在尝试从 jsp 文件 (WEB-INF/jsp/index.jsp) 访问 css 和 js 文件时遇到问题。我通读了 Stack Overflow 上其他人面临的一些类似问题。

我将这行代码添加到我的 SpringMVCProj-servlet.xml 中，它使事情变得更加复杂。

<mvc:resources mapping="/WebContent/**" location="/WebContent/" />

SpringMVCProj-servlet.xml

<context:component-scan base-package="com.myapp" />
<mvc:resources mapping="/WebContent/**" location="/WebContent/" />

<bean
    class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="prefix" value="/WEB-INF/jsp/" />
    <property name="suffix" value=".jsp" />
</bean>

Web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
  <display-name>Spring MVC Application</display-name>

  <welcome-file-list>
<!--     <welcome-file>/WEB-INF/jsp/index.jsp</welcome-file>
 -->    
 <welcome-file>/WEB-INF/jsp/index.jsp</welcome-file>
  </welcome-file-list>

   <servlet>
      <servlet-name>SpringMVCProj</servlet-name>
      <servlet-class>
         org.springframework.web.servlet.DispatcherServlet
      </servlet-class>
      <load-on-startup>1</load-on-startup>
   </servlet>

   <servlet-mapping>
      <servlet-name>SpringMVCProj</servlet-name>
      <url-pattern>/</url-pattern>
   </servlet-mapping>

<context-param>
   <param-name>contextConfigLocation</param-name>
   <param-value>/WEB-INF/SpringMVCProj-servlet.xml</param-value>
</context-param>

<listener>
   <listener-class>
      org.springframework.web.context.ContextLoaderListener
   </listener-class>
</listener>


</web-app>

这是在我添加代码行之前。

    <mvc:resources mapping="/WebContent/**" location="/WebContent/" />

这之后...

在我将 SpringMVCProj-servlet.xml 更改为此之后，它起作用了。

<?xml version="1.0" encoding="UTF-8"?>
