錯誤

localhost:8080 404 error 

warnings: No mapping found for HTTP request with URI [/hello] in DispatcherServlet with name 'mvc-dispatcher' 
Jan 02, 2016 12:15:40 org.springframework.web.servlet.PageNotFound noHandlerFound 

localhost:8080/log no response 

會有人可以給我一種幫助嗎？非常感謝。

您映射爲hello.jsp頁面/在HelloController中，如果你希望它是在/hello擔任修改它的代碼如下

@RequestMapping("/hello")//instead of @RequestMapping("/") 
public String printWelcome(ModelMap model) { 
    model.addAttribute("message", "Hello world!"); 
    return "hello"; 
}
