Java 在实现spring MVC时，没有发现任何处理程序错误

我一直试图从web上运行这个示例项目来学习spring mvc，但面临以下问题：

Mar 03, 2019 8:47:53 PM org.springframework.web.servlet.PageNotFound noHandlerFound
WARNING: No mapping found for HTTP request with URI [/springmvcexample/employee-module] in DispatcherServlet with name 'spring'

我点击的URL是：

以下是相关文件：

EmployeeController类

@Controller
@RequestMapping("/employee-module")
public class EmployeeController 
{
    @Autowired
    EmployeeManager manager;

    @RequestMapping(value = "/getAllEmployees", method = RequestMethod.GET)
    public String getAllEmployees(Model model)
    {
        model.addAttribute("employees", manager.getAllEmployees());
        return "employeesListDisplay";
    }
}

有人能帮忙吗

下面是已部署应用程序的服务器视图的屏幕截图

为什么不

http://localhost:8080/springmvcexample/employee-模块/getAllEmployees

？仍然获得相同的issue@ghostrider正如我所说，通过服务器视图发布带有已部署工件的对话框屏幕截图。@LppEdd发布的屏幕截图
