如果查看
Java EE FrontController序列图,Controller会将请求委托给Dispatcher,文档说：
A dispatcher is responsible for view management and navigation,
@H_502_7@
managing the choice of the next view to present to the user,and
providing the mechanism for vectoring control to this resource.在Spring MVC中,DispatcherServlet充当FrontController(如Craig Walls一书中所述),此Servlet将请求委托给其他控制器,后者又调用适当的Service类(用于处理请求),然后将ModelAndView的实例返回给DispatcherServlet再次.
所以大致这是请求通常的旅行方式：
客户 – > DispatcherServlet – >控制器 – >服务 – > DAO
如果将此流与Java EE FrontController模式序列图进行比较,则看起来DispatcherServlet不是真正的FrontController.
你怎么说这个？
