当我运行主程序时，它会抛出异常
“无法编译映射文档：NHibernateDemo.Order.hbm.xml” 在线： cfg.AddAssembly（Assembly.GetExecutingAssembly（））;在里面 ConfigureNHibernate（）方法。
请你提一些建议吗？
Below are my implementations
I have a Customer class that has another class Location which maps to the same table "Customer":
public class Customer
{
public Customer()
{
MemberSince = DateTime.UtcNow;
Orders = new HashSet<Order>();
}
public virtual Guid Id { get; set; }
public virtual string FirstName { get; set; }
public virtual string LastName { get; set; }
public virtual double AverageRating { get; set; }
public virtual int Points { get; set; }
public virtual bool HasGoldStatus { get; set; }
public virtual DateTime MemberSince { get; set; }
public virtual CustomerCreditRating CreditRating { get; set; }
public virtual Location Address { get; set; }
public virtual ISet<Order> Orders { get; set; }
public virtual void AddOrder(Order order) { Orders.Add(order); order.Customer = this; }
public override string ToString()
{
var result = new StringBuilder();
result.AppendFormat("{1} {2} ({0})\r\n\tPoints: {3}\r\n\tHasGoldStatus:" +
"{4}\r\n\tMemberSince: {5} ({7})\r\n\tCreditRating: {6}\r\n\tAverageRating:" +
"{8}\r\n", Id, FirstName, LastName, Points, HasGoldStatus, MemberSince,
CreditRating, MemberSince, AverageRating);
result.AppendLine("\tOrders:");
foreach (var order in Orders)
{
result.AppendLine("\t\t" + order);
}
return result.ToString();
}
}
public class Location
{
public virtual string Street { get; set; }
public virtual string City { get; set; }
public virtual string Province { get; set; }
public virtual string Country { get; set; }
}
public enum CustomerCreditRating
{
Excellent,
VeryVeryGood,
VeryGood,
Good,
Neutral,
Poor,
Terrible
}
The Customer table was created as follows:
CREATE TABLE [dbo].[Customer] (
[Id] UNIQUEIDENTIFIER NOT NULL,
[FirstName] NVARCHAR (100) NOT NULL,
[LastName] NVARCHAR (100) NOT NULL,
[Points] INT NULL,
[HasGoldStatus] BIT NULL,
[MemberSince] DATE NULL,
[CreditRating] NCHAR (20) NULL,
[AverageRating] DECIMAL (18, 4) NULL,
[Street] NVARCHAR (100) NULL,
[City] NVARCHAR (100) NULL,
[Province] NVARCHAR (100) NULL,
[Country] NVARCHAR (100) NULL,
PRIMARY KEY CLUSTERED ([Id] ASC)
);
CREATE TABLE [dbo].[Order] (
[Id] UNIQUEIDENTIFIER NOT NULL,
[CustomerId] UNIQUEIDENTIFIER NULL,
[Ordered] DATETIME NULL,
[Shipped] DATETIME NULL,
[Street] NVARCHAR (100) NULL,
[City] NVARCHAR (100) NULL,
[Province] NVARCHAR (100) NULL,
[Country] NVARCHAR (100) NULL,
PRIMARY KEY CLUSTERED ([Id] ASC)
);
My Customer configuration xml is as follows:

目的是创建一个新客户和一个订单对象，作为一个集合项目添加到客户，并保存客户对象，以便自动将其写入客户和订单数据库。 该错误似乎与映射到订单表有关。
