SpringMVC访问静态资源

如果你的DispatcherServlet拦截“/”,拦截了所有的请求,同时对*.js,*.jpg的访问也就被拦截了,所以很可能出现访问不到静态资源,报404的问题。如:

<servlet>
        <servlet-name>dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:dispatcher-servlet.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

以上配置的DispatcherServlet拦截了所有的请求,因此在springMVC配置静态资源的访问路径(dispatcher-servlet.xml),如:

<!-- 静态文件的访问 -->
    <mvc:resources location="/ExtJS4.2/" mapping="/ExtJS4.2/**"/>
    <mvc:resources location="/demo/image/" mapping="/demo/image/**"/>
    <mvc:resources location="/demo/js/" mapping="/demo/js/**"/>
    <mvc:resources location="/demo/config/" mapping="/demo/config/**"/>

那么在页面中写静态文件的路径就按以上映射(mapping)的地址。如:

<script type="text/javascript" src="/demo/js/localXHR.js"></script>
store: new Ext.data.TreeStore({
            proxy: {
                type: 'ajax',
                url: '/demo/config/tree.txt'// 'demo/config/tree.txt'也可以。与resource中的dispatcher-servlet.xml静态资源映射地址一致。
            },
            root: {
                expand: true,
                text: '我是根'
            }
        }),
