restygwtを使用してサーバーとクライアントの通信を試みています。したがって、サービス インターフェイス (クライアント) とコントローラー (サーバー) があります。
@Path("/user")
public interface UserAdminRestService extends RestService {
@GET
@Path("/users")
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
public void getUsers(MethodCallback<List<GWTUser>> methodCallback);
@GET
@Path("/{id}")
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
public void getUser(Integer id, MethodCallback<GWTUser> callback);
}
@Controller
@RequestMapping(value ="/user")
public class AdminSpringController {
@RequestMapping(value = "/users", method = RequestMethod.GET)
@ResponseStatus(HttpStatus.OK)
public @ResponseBody List<GWTUser> getUsers() {
...
}
@RequestMapping( value = "/{id}", method = RequestMethod.GET)
@ResponseStatus(HttpStatus.OK)
public @ResponseBody GWTUser getUser(@PathVariable Integer id) throws NotFoundException { ...
}
}
特定のデータを取得するには、MethodCall を作成します。
Defaults.setServiceRoot(GWT.getHostPageBaseURL());
UserAdminRestService userService = GWT.create(UserAdminRestService.class);
((RestServiceProxy)userService).setResource(new Resource("/user"));
userServiceClient.getUsers(new MethodCallback<List<GWTUser>>() {
@Override
public void onFailure(Method method, Throwable exception) {
// TODO Auto-generated method stub
}
@Override
public void onSuccess(Method method, List<GWTUser> response) {
view.setUserList(response);
}
});
しかし、アプリケーションをビルドしようとすると、次のエラー メッセージが表示されます。
[INFO] Compiling module my.app.web
[INFO] Computing all possible rebind results for 'my.app.client.UserAdminRestService'

LINE 69: はUserAdminRestService userService = GWT.create(UserAdminRestService.class);
何が間違っているのかわかりません。アイデアや助けをありがとう:)

UserAdminRestServiceインターフェイスと の両方GWTUserがまだ同じ であるため、2 つのモジュールのために問題があると思います。
