Java 我在启动服务器时遇到以下问题。找不到URL为的HTTP请求的映射

如何解决这个问题。我有index.jsp，但它没有打开该jsp我能做什么

错误是：在名为“rest”的DispatcherServlet中找不到URI为[/RoomController/]的HTTP请求的映射

控制器类为：

@RestController
@RequestMapping("/Room/")
public class RoomController {

@Autowired
RoomDao roomDao;

@RequestMapping(method = RequestMethod.GET,headers="Accept=application/json")
public String getAllUsers() {
    String users="hello welcome ";
    return users;
}

@RequestMapping(value="/ViewMember",method = RequestMethod.GET)
public List<RoomMembers> getRoomMembers() {
    List<RoomMembers> roomMemberList= new ArrayList<RoomMembers>();
    roomMemberList=roomDao.listMember();
    return roomMemberList;
}

@RestController
@请求映射（“/Room/”）
公共教室管理员{
@自动连线
RoomDao RoomDao；
@RequestMapping（method=RequestMethod.GET，headers=“Accept=application/json”）
公共字符串getAllUsers（）{
String users=“hello welcome”；
返回用户；
}
@RequestMapping（value=“/ViewMember”，method=RequestMethod.GET）
公共列表getRoomMembers（）{
List roomMemberList=新建ArrayList（）；
roomMemberList=roomDao.listMember（）；
返回roomMemberList；
}

您的映射配置不正确。您可以使用

@RequestMapping

将控制器与URI映射，方法是在其中指定

值

属性，如下所示：

@RequestMapping(value="/")
public String displayGui(ModelMap model) {
        // Add value to model
        model.addAttribute(...);
        model.addAttribute(...);

        //return to view index.jsp
        return "index";
}

@请求映射（值=“”）

---

因此，当您定义上述控制器时，您可以通过

/Room/

而不是/RoomController

访问它，控制器中应该有一个默认映射为“/RoomController”的方法，该方法返回index.jsp作为视图部分，如下所示：

@RequestMapping(value="/")
public String displayGui(ModelMap model) {
        // Add value to model
        model.addAttribute(...);
        model.addAttribute(...);

        //return to view index.jsp
        return "index";
}

---

因此，当您点击时，将调用上面的displayGui方法，并返回index.jsp/

i was remove/Room/意味着它下载了一个json文件，我想打开index.jsp。那么，如果您想访问index.jsp，那么我想做什么更改呢？只需使用

@Controller

注释，其中一个方法定义为提供视图名称作为返回值。
