如何通过 DbContext 访问门面接口？

问：

我有一个棘手的问题，如果有人能帮助我解决这个问题，那就太好了。 有一个用于修改实体的 facade 类，我想在发生操作时获取用户的操作并将其存储在 UsersActionsLog 实体中：

 public class UsersActionsLog
    {
        [Key]
        public long Id { get; set; }
        public long UserId { get; set; }
        public string Entity { get; set; }
        public string? PrimaryKeyValue { get; set; }
        public string PropertyName { get; set; }
        public string OldValue { get; set; }
        public string NewValue { get; set; }
        public string Action { get; set; } // [0]=Added [1]=Modified [2]=Deleted
        public bool Successful { get; set; } // [false]= failed [true]=successful
        public DateTime Date { get; set; } = DateTime.Now;
    }

我正在使用 facade 模式来执行代码。 我的服务：

    public class RequestPostUserActionLogServiceDto
    {
        public long UserId { get; set; }
        public string Entity { get; set; }
        public string? PrimaryKeyValue { get; set; }
        public string PropertyName { get; set; }
        public string OldValue { get; set; }
        public string NewValue { get; set; }
        public string Action { get; set; } // [0]=Added [1]=Modified [2]=Deleted
        public bool Successful { get; set; } // [false]= failed [true]=successful
    }
    public interface IPostUserActionLogService
    {
        bool Execute(RequestPostUserActionLogServiceDto req);
    }
    public class PostUserActionLogService: IPostUserActionLogService
    {
        private readonly IDataBaseContext _context;
        public PostUserActionLogService(IDataBaseContext context)
        {
            _context = context;
        }
        public bool Execute(RequestPostUserActionLogServiceDto req)
        {
            return true;
        }
    }

我的外表：

 public class UserActionsLogFacade: IUserActionLogFacade
    {
        private readonly IDataBaseContext _context;
        public UserActionsLogFacade(IDataBaseContext context)
        {
            _context = context;
        }
        ///////////////////////////////////// PostUserActionLogService
        private PostUserActionLogService _postUserActionLogService;
        public PostUserActionLogService PostUserActionLogService
        {
            get { return _postUserActionLogService = _postUserActionLogService ?? new PostUserActionLogService(_context); }
        }
    }

和：

    public interface IUserActionLogFacade
    {
        public PostUserActionLogService PostUserActionLogService { get;}
    }

我正在尝试在“DataBaseContext”中注入“ISerActionLogFacade”，但我遇到了一个错误 [检测到类型服务的循环依赖关系] 在此处输入图像描述

    public class DataBaseContext : DbContext, IDataBaseContext
    {
        private IUserActionLogFacade _userActionLogFacade;
        public DataBaseContext(DbContextOptions option, IUserActionLogFacade userActionLogFacade) : base(option)
        {
            _userActionLogFacade = userActionLogFacade;
        }

        // Tables
        public DbSet<Users> Users { get; set; } // Users Table
        public DbSet<Roles> Roles { get; set; } // Roles Table
        public DbSet<UsersInRoles> UsersInRoles { get; set; } // UsersInRoles Table
        public DbSet<UsersActionsLog> UsersActionsLog { get; set; } // UsersActionsLog Table

        protected override void OnModelCreating(ModelBuilder modelBuilder)
        {
            //> FLuent API of Entity Configurations
            //---- Users
            modelBuilder.ApplyConfiguration(new UsersConfigurations());
            //---- ROles
            modelBuilder.ApplyConfiguration(new RolesConfigurations());
            //< End
        }
        public override int SaveChanges()
        {
            var modifiedEntries = ChangeTracker.Entries()
                .Where(
                    e =>
                    e.State == EntityState.Modified ||
                    e.State == EntityState.Added ||
                    e.State == EntityState.Deleted
                    );


            foreach (var entry in modifiedEntries)
            {
                var entityType = entry.Context.Model.FindEntityType(entry.Entity.GetType());
                var inserted = entityType.FindProperty("InsertDate");
                var updated = entityType.FindProperty("UpdateDate");
                var deleted = entityType.FindProperty("DeleteDate");

                switch (entry.State)
                {
                    case EntityState.Added:
                        if (inserted != null) entry.Property("InsertDate").CurrentValue = DateTime.Now;
                        break;
                    case EntityState.Modified:
                        if (updated != null) entry.Property("UpdateDate").CurrentValue = DateTime.Now;
                        break;
                    case EntityState.Deleted:
                        if (deleted != null) entry.Property("DeleteDate").CurrentValue = DateTime.Now;
                        entry.State = EntityState.Modified;
                        break;
                }


                _userActionLogFacade.PostUserActionLogService.Execute( new RequestPostUserActionLogServiceDto 
                {
                    Entity = entry.Entity.GetType().Name, //entityName 
                    Action = "",
                    NewValue = "",
                    OldValue = "",
                    PrimaryKeyValue = "1",
                    PropertyName = "",
                    Successful = true,
                    UserId = 1,
                });
            }
            return base.SaveChanges();
        }
    }

当然，我看到了这个问题：我看到了这个问题：DbContext Override SaveChanges 没有触发，但问题是，基于该问题，应答者直接解决了问题。我的意思是，由于 CLEAN ARCHITATURE 结构，我们不能直接在 PERSISTENCE 层中使用 DOMIAN 层。 那么，如何在 OVERRIED SAVECHANGE（） 方法中注入 Facade 并使用其服务呢？
