spring - how to use the classpath location

Question

为了解决这个问题，我进行了上下搜索，但是找不到解决方案。
问题如下:
我在Tomcat 7服务器上创建了一个Spring-mvc Web应用程序-确切地说是7.0.12-我无法使<mvc:resources>标记正常工作。正如您将在下面看到的，<mvc:resources>适用于旧资源文件夹，但是我更喜欢将资源文件夹放在/WEB-INF/web/目录中。

MediorkoorVOICES-Web-servlet.xml:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns:context="http://www.springframework.org/schema/context"
   xmlns:mvc="http://www.springframework.org/schema/mvc"
   xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
      http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd
      http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">        

    <context:component-scan base-package="com.oudejans.mediorkoorvoices.web" /> 

    <mvc:resources mapping="/resources/**" location="/WEB-INF/web/resources/"  />  
    <mvc:annotation-driven />

    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
        <property name="prefix" value="/WEB-INF/web/jsp/" />
        <property name="suffix" value=".jsp" />
        <property name="order" value="1" />
    </bean>

    <bean id="handlerMapping" class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" /> 

    <import resource="web/tiles/web-tiles.xml" />
</beans>

文件夹结构:

META-INF
resources (Old resources folder)
    - web
        - images
        - css
            - main.css      
WEB-INF
    - classes
    - lib
    - admin
    - shared
    - web
        - jsp
        - tiles
        - resources (New resources folder i want to access)
            - images
                - banner.png
            - js
            - etc.

现在，如果我想访问旧的资源文件夹，下面的代码将起作用。

<mvc:resources mapping="/resources/**" location="/resources/" />
&
<img src="${pageContext.request.contextPath}/resources/oldBanner.png" />

但是我更喜欢做这样的事情:

<mvc:resources mapping="/resources/**" location="classpath:/WEB-INF/web/resources/" />
&
<img src="${pageContext.request.contextPath}/resources/images/banner.png" />

有人可以向我解释我该怎么做吗？我是spring-mvc的新手。

EDIT1:其他数据:我使用的是netbeans 7.1.2，spring-mvc版本是3.1.0与maven结合在一起。

EDIT3:经过更多测试后，我意识到 <mvc:resources>标记根本不起作用。 (查看更新的文件夹结构)，例如，如果我执行以下操作:

<mvc:annotation-driven />
<mvc:resources location="/resources/web/" mapping="/resources/**" /> 
&
<a href="${pageContext.request.contextPath}/resources/css/main.css" />click</a>

它也给我一个404，实际上，它应该链接到/resources/web/css/main.css文件。因此，我现在能想到的就是有些未命中的配置。

Answer 1

因此，在进行了大量调试和“尝试”之后，我尝试将* .css和* .png映射添加到web.xml servlet中。显然，资源文件未映射到servlet，因此无法找到。因此，对于与我的映射相同的每个人，请将其添加到您的web.xml servlet-mapping 标记中。

<url-pattern>*.css</url-pattern>
<url-pattern>*.png</url-pattern>
