啟動項目時，找不到帶有URI的HTTP請求的映射

Question

請檢查並提示在配置項目開始時出錯的地方，因為出現錯誤“找不到帶有URI的HTTP請求的映射”。 以下代碼已添加到項目中。 1.web.xml 2.servlet-context.xml 3. @控制器

另外，在我的樹形設計的屏幕上添加了一個鏈接。 http://zapodaj.net/17ab5a68373a9.png.html

@Controller
public class UserController {

    @Autowired
    private UserServiceImpl userServiceImpl; 

    @RequestMapping(value = "/home", method = RequestMethod.GET)
    public String home(Model model) {

        model.addAttribute("allUsers", userServiceImpl.allUsers() );

        return "home";
    }

}

Answer 1

1）。 插件seervlet-context.xml：

<mvc:annotation-driven></mvc:annotation-driven>

2）。 如下更改web.xml中的servlet映射：

 <servlet-mapping>
    <servlet-name>appServlet</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>
