我是按照下面这样写的，但是会报错。

public class TestBase extends Assert {

    protected Ioc ioc;

    @Before
    public void before() throws Exception {
        ioc = new NutIoc(new ComboIocLoader("*anno", "cn.wizzer","org.nutz","io.nutz"));
        _before();
    }

    @After
    public void after() throws Exception {
        _after();
        if (ioc != null) {
            ioc.depose();
        }
    }

    protected void _before() throws Exception {}
    protected void _after() throws Exception {}
}

 @Test
    public void testLogin(){
        LoginService service = ioc.get(LoginServiceImpl.class);
        NutMap resp = service.login("", "");
        System.out.println(Json.toJson(resp));
    }

@IocBean
@Service(interfaceClass=LoginService.class)
public class LoginServiceImpl implements LoginService{
    @Inject
    private PropertiesProxy conf;
    @Inject
    RedisService redisService;
.....
}
