web.xml 加上

1. <servlet>       
2.   <servlet-name>DruidStatView</servlet-name>     
3.   <servlet-class>com.alibaba.druid.support.http.StatViewServlet</servlet-class>  
4. </servlet>   
5. <servlet-mapping>     
6.    <servlet-name>DruidStatView</servlet-name>  
7.    <url-pattern>/druid/*</url-pattern>  
8.  </servlet-mapping>   

就可以了.
