spring mvc 的<mvc:resources mapping="***" location="***">標(biāo)簽是用來(lái)進(jìn)行配置靜態(tài)資源訪問(wèn)的。

<servlet>  
    <servlet-name>springMVC</servlet-name>  
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>  
    <load-on-startup>1</load-on-startup>  
</servlet>  
  
<servlet-mapping>  
    <servlet-name>springMVC</servlet-name>  
    <url-pattern>/</url-pattern>  
 </servlet-mapping>  

spring mvc會(huì)在WEB-INF下掃描一個(gè)springMVC-servlet.xml文件，如果沒(méi)有提供，將會(huì)報(bào)一個(gè)文件找不到的異常。
由于spring mvc攔截了所有請(qǐng)求

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

訪問(wèn)靜態(tài)資源文件的時(shí)候也會(huì)被DispatcherServlet攔截，而且會(huì)進(jìn)行一系列復(fù)雜的處理，所以對(duì)靜態(tài)資源必須進(jìn)行特殊的配置。
