上篇文章主要讲述了经销商上下文的需求与POCO对象，这篇文章主要讲述该界限上下文的仓储与领域逻辑的实现。
关于界限上下文与EF Core数据访问上下文参考产品上下文相应的实现，这里不再累述。
因为在经销商上下文中有两个聚合，一个是经销商聚合，一个是登录聚合，所以我们需要实现两个仓储接口：
1.经销商仓储接口定义：
public interface IDealerRepository
{
void CreateDealer<T>(T dealer) where T : class, IAggregationRoot;
//获取上级经销商(当前代注册经销商)的层次结构
int GetParentDealerLayer(Guid dealerid);
//将上级经销商（代注册经销商）的子个数加一
void AddParentSubCount(Guid? parentdealerid);
//减去父进销商的电子币（用于注册和下单时，扣减经销商的电子币）
void SubParentEleMoney(Guid parentdealerid, decimal subelemoney);
//下订单时，增加经销商的PV
void AddDealerPV(Guid dealerid, decimal orderpv); }
2.登录仓储接口定义：
public interface ILoginRepository
{
void CreateLogin<T>(T login) where T : class, IAggregationRoot;
Guid UserLogin(string tel, string password);
}
3.具体对应的仓储实现在仓储实现的项目中自己实现，主要通过EF Core完成数据库的访问与操作。
4.经销商聚合中联系人对象的领域逻辑实现：
public partial class Contact
{
public Contact CreateContact(Guid dealerid,string name,string tel,string province,string city,
string zero,string street,int isdefault)
{
this.Id = Guid.NewGuid();
this.DealerId = dealerid;
this.ContactName = name;
this.ContactTel = tel;
this.Province = province;
this.City = city;
this.Zero = zero;
this.Street = street;
switch (isdefault)
{
case :this.IsDefault = IsDefaultContact.默认;
break;
case :this.IsDefault = IsDefaultContact.非默认;
break;
}
return this; }
}
5.经销商聚合中经销商层次结构对象的领域逻辑实现：
public partial class DealerTree
{
private readonly IDealerRepository idealerrepository;
public DealerTree(IDealerRepository idealerrepository)
{
this.idealerrepository = idealerrepository;
}
public DealerTree CreateDealerTree(Guid? parentdealerid,Guid dealerid)
{
this.Id = Guid.NewGuid();
this.DealerId = dealerid;
this.ParentDealerId = parentdealerid;
this.Layer = parentdealerid == null ? : idealerrepository.GetParentDealerLayer(Guid.Parse(parentdealerid.ToString())) + ;
return this;
}
}
6.经销商聚合中经销商对象的领域逻辑实现：
public partial class Dealers
{
private readonly IDealerRepository idealerrepository;
public Dealers(IDealerRepository idealerrepository)
{
this.idealerrepository = idealerrepository;
}
public Dealers RegisterDealer(Guid id,string name,string tel,decimal telmoney,List<Contact>
contacts,Guid? parentid)
{
this.Id = id;
this.Code = "Code " + name;
this.Name = name;
this.Tel = tel;
this.TotalEleMoney = telmoney;
if (telmoney < )
{
this.CardType = CardType.普通会员;
}
else if (telmoney >= && telmoney < )
{
this.CardType = CardType.银卡会员;
}
else
{
this.CardType = CardType.金卡会员;
}
this.SubCount = ;
this.TotalPV = ;
this.JiangJInMoney = ;
this.Contacts = contacts;
this.DealerTree = new DealerTree(idealerrepository).CreateDealerTree(parentid, id);
return this;
}
}
7.登录聚合中登录对象的领域逻辑实现：
public partial class Login
{
public Login CreateLogin(string code,Guid dealerid)
{
this.Id = Guid.NewGuid();
//手机号
this.Code = code;
//默认初始密码
this.Password=MD5Encrption.GetMd5Str("");
this.DealerId = dealerid;
return this;
}
}
这样，我们就完成了基本数据库的访问、操作和相关领域逻辑的实现。
