我是MVC的新手。爲什麼請求不會從hello.jsp傳輸到控制器?
我想用Spring MVC構建一個簡單的hello world應用程序。 我得到404錯誤,因爲href不會轉到hello.jsp。我在我的WEB-INf和index下有我的hello.jsp,jsp在Web應用下。以下是我的應用程序代碼。謝謝大家提前
@Controller
public class HelloController {
@RequestMapping(value = "/hello",method = RequestMethod.POST)
public ModelAndView mymethod(){
return new ModelAndView("hello","msg","Hello First Spring");
}
}
