你好，我得到了一个非常简单的服务，看起来像这样：

public class LessonAppService :ApplicationService,
    ILessonService //implement the IBookAppService
    {
        private readonly IRepository<Lesson, Guid> _lessonRepository;

        public LessonAppService(IRepository<Lesson, Guid> lessonRepository)
        {
            _lessonRepository = lessonRepository;
        }

        public async Task CreateLessonAsync(CreateLessonDTO input)
        {
            try
            {
                var lesson = ObjectMapper.Map<CreateLessonDTO, Lesson>(input);
                await _lessonRepository.InsertAsync(lesson);
            }
            catch (Exception ex)
            {

                throw;
            }

        }

由此创建的API路由是：/API/应用程序/课程/课程
而所有其他端点看起来像这样：/API/帐户/登录
你知道为什么吗？怎么解决？
