<!--配置默认的servlet处理静态资源
当前工程的web.xml配置的前端控制器DispatcherServlet的url-pattren是/
tomcat的web.xml配置的DefaultServlet的url-pattern也是/
此时，浏览器发送的请求会优先被DispatcherServlet进行处理，但是DispatcherServlet无法处理静态资源
若配置了 <mvc:default-servlet-handler/>和 <mvc:annotation-driven/>
浏览器发送的请求会先被DispatcherServlet处理，无法处理再交给DefaultServlet处理

view-name：设置请求地址所对应的视图名称
