spring静态资源的访问

在进行Spring MVC的配置时，通常我们会配置一个dispatcher servlet用于处理对应的URL。配置如下：

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

只拦截.do请求配置如下：

   <servlet>
        <servlet-name>SpringMVC</servlet-n
