我知道有几十个类似的主题,但我找不到任何解决方案。我想使用 spring mvc 制作简单的“hello world”应用程序。它给了我 404 的描述:请求的资源不可用。在控制台中:
wrz 13, 2013 7:38:14 PM org.springframework.web.servlet.DispatcherServlet noHandlerFound
WARNING: No mapping found for HTTP request with URI [/gitsystem/] in DispatcherServlet with name 'dispatcher'
控制器.java:
package bg.glowacki.gitsystem.controller;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
@Controller
public class Controller {
@RequestMapping("/")
public String printHelloWorld(Model model) {
model.addAttribute("message", "Hello World!");
return "helloWorld";
}
}
