springmvc-01

api==>应用程序编程接口

 

 The word 'zhong' is not correctly spelled==>拼写不正确(没啥事,不用管),

 res cannot be resolved to a variable ==>无法将RES解析为变量(变量名写错);

resp cannot be resolved or is not a field ==> 无法解决或不是字段(req,resp逗号);

The method forwaed(HttpServletRequest, HttpServletResponse) is undefined for the type RequestDispatcher ==>

对于类型Request Dispatcher，fwaed方法(Http Servlet Request，Http Servlet Response)未定义(方法名写错forward);
