有人吗，求解答

。。。

@RequestMapping("/response")
public class ResponseController {
@RequestMapping("/basicForward")
public void basicForward(HttpServletRequest request, HttpServletResponse response) throws Exception {
request.getRequestDispatcher("/WEB-INF/pages/forward.jsp").forward(request,response);
}
@RequestMapping("/basicRedirect")
public void basicRedirect(HttpServletRequest request, HttpServletResponse response) throws Exception {
String contextPath = request.getContextPath();
System.out.println(contextPath);
response.sendRedirect(contextPath + "/WEB-INF/pages/redirect.jsp");
}
//使用了forward、redirect关键字后将不会调用视图解析器
@RequestMapping("/forward")
public String forward(){
System.out.println("forward方法执行了。。。");
return "forward:/WEB-INF/pages/forward.jsp";
}
@RequestMapping("/redirect")
public String redirect(){
System.out.println("redirect方法执行了。。。");
//原本的重定向需要写项目名称路径，用了关键字后不用加
return "redirect:/WEB-INF/pages/redirect.jsp";
}

目录结构也发了
