SpringMVC访问静态资源

在SpringMVC中常用的就是Controller与View。但是我们常常会需要访问静态资源，如html,js,css，image等。

默认的访问的URL都会被DispatcherServlet所拦截，但是我们希望静态资源可以直接访问。该肿么办呢？

在配置文件：web.xml可以看到：

    <!-- 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>

静态资源访问，其实方法有多种，如：通过开放tomcat的defaultServlet，修改默认的url-parttern。

但是SpringMVC提供了更为便捷的方式处理静态资源。

解决方案：

直接在servlet-context.xml中添加资源映射。

我的开发环境：

1、Eclipse Luna SP1

2、Springsource-tool-suite 3.6.4 

修改servlet-context.xml，添加resource映射即可。

servlet-context.xml的路径如下：

配置文件内容：
