springmvc中url-pattern的大坑

 1 <servlet>
 2         <servlet-name>springmvc</servlet-name>
 3         <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
 4         <load-on-startup>1</load-on-startup>
 5     </servlet>
 6     <servlet-mapping>
 7         <servlet-name>springmvc</servlet-name>
 8         <!-- 切记不能是<url-pattern>/</url-pattern>，否则报404 -->
 9         <url-pattern>/*</url-pattern>
10     </servlet-mapping>

本人愚钝，切勿吐槽，愿与君共勉之！
