请问有人可以帮我吗？已经有两天多了！
Please can anyone help me out in this? It has been more than two days struck with it !!!
推荐答案
您的返回消息
ModelAndView msg = new ModelAndView();
msg.setViewName("results");
msg.addObject("message",message);
System.out.println ("before return" +message);
return msg;
不是一个消息！它是一个模型（键消息：值消息）和视图（result）
视图是应该呈现的jsp文件的名称。而且你没有这样的一个jsp文件（这就是警告没有找到HTTP请求与URI的映射[/projectdemo/WEB-INF/jsp/results.jsp] 抱怨）
is not a message! It is a model (key "message": value message) and a view ("result")
The view is the name of an jsp file that should be rendered. And you do not have such an jsp file (that is what the Warning No mapping found for HTTP request with URI [/projectdemo/WEB-INF/jsp/results.jsp] complains)
您需要编写这个jsp文件并将其存储在 /WEB-INF/jsp/results.jsp ！
You need to write this jsp file and store it in /WEB-INF/jsp/results.jsp!
