我正在使用Jukito测试一个GWTP演示者，似乎无法使命名绑定工作。
我希望能够测试我的登录小部件的onReveal()，因此我需要提供一个已登录的CurrentUserDto的副本，以及一个未登录的副本。这就是我要做的：

@RunWith(JukitoRunner.class)
public class LoginWidgetPresenterTest
{
    public static class Module extends JukitoModule
    {
        @Override
        protected void configureTest()
        {
            bind(CurrentUserDto.class).annotatedWith(Names.named("loggedIn")).toProvider(LoggedInUserProvider.class);
            bind(CurrentUserDto.class).annotatedWith(Names.named("loggedOut")).toProvider(LoggedOutUserProvider.class);

            // these don't work either:
            // bindNamed(CurrentUserDto.class, "loggedIn").toProvider(LoggedInUserProvider.class);
            // bindNamed(CurrentUserDto.class, "loggedOut").toProvider(LoggedOutUserProvider.class);
        }

        public static class LoggedInUserProvider implements Provider<CurrentUserDto>
        {
            @Override
            public CurrentUserDto get()
            {
                CurrentUserDto currentUser = new CurrentUserDto(true, 100L); // isLoggedIn, userId
                currentUser.setEmail("john@example.com");
                currentUser.setNickname("john");
                currentUser.setLogoutUrl("#logout");

                return currentUser;
            }
        }

        public static class LoggedOutUserProvider implements Provider<CurrentUserDto>
        {
            @Override
            public CurrentUserDto get()
            {
                CurrentUserDto currentUser = new CurrentUserDto(false, null); // isLoggedIn, userId

                return currentUser;
            }
        }

    }

    @Inject
    LoginWidgetPresenter presenter;

    @Test
    public void testLoggedInUser(LoginWidgetPresenter.MyView myView, @Named("loggedIn") CurrentUserDto currentUser)
    {
        // when
        presenter.onReveal();

        // then
        verify(myView).displayEmail(currentUser.getEmail());
        verify(myView).displayLogoutLink(currentUser.getLogoutUrl());

    }

    @Test
    public void testLoggedOutUser(LoginWidgetPresenter.MyView myView, @Named("loggedOut") CurrentUserDto currentUser)
    {
        // when
        presenter.onReveal();

        // then
        verify(myView, never()).displayEmail(currentUser.getEmail());
        verify(myView, never()).displayLogoutLink(currentUser.getLogoutUrl());

    }

}

我怀疑这可能与作用域有关，但我是依赖注入的新手，所以我仍然了解它。
当我只有一个提供者时，它工作得很好，现在我使用@Named，LoginWidgetPresenter中的CurrentUserDto对象总是空的。
