我試圖從Fluent Nhibernate支持網站運行一個例子，我沒有在控制檯應用程序內運行它，而是在MVC 3項目中實現它，它打擊我的錯誤：系統。 Data.SqlClient.SqlException：無效的對象名稱'Store'。流利的Nhibernate教程運行時錯誤：無效的對象名稱
我的映射是這樣的：
StoreMap.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using MvcApplication1.Models.Domain;
using FluentNHibernate.Mapping;
namespace MvcApplication1.Mappings
{
public class StoreMap : ClassMap<Store>
{
public StoreMap()
{
Table("Store");
Id(x => x.Id);
Map(x => x.Name);
HasMany(x => x.Staff)
.Inverse()
.Cascade.All();
HasManyToMany(x => x.Products)
.Cascade
.All()
.Table("StoreProduct");
}
}
}
ProductMap.cs：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using MvcApplication1.Models.Domain;
using FluentNHibernate.Mapping;
namespace MvcApplication1.Mappings
{
public class ProductMap : ClassMap<Product>
{
public ProductMap()
{
Id(x => x.Id);
Map(x => x.Name);
Map(x => x.Price);
HasManyToMany(x => x.StoresStockedIn)
.Cascade
.All()
.Inverse()
.Table("StoreProduct");
}
}
}
EmployeeMap.cs：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using MvcApplication1.Models.Domain;
using FluentNHibernate.Mapping;
namespace MvcApplication1.Mappings
{
public class EmployeeMap : ClassMap<Employee>
{
public EmployeeMap()
{
Id(x => x.Id);
Map(x => x.FirstName);
Map(x => x.LastName);
References(x => x.Store);
}
}
}
Store.cs：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
namespace MvcApplication1.Models.Domain
{
public class Store
{
public virtual int Id { get; private set; }
public virtual string Name { get; set; }
public virtual IList<Product> Products { get; set; }
public virtual IList<Employee> Staff { get; set; }
public Store()
{

Staff = new List<Employee>();
}
public virtual void AddProduct(Product product)
{
product.StoresStockedIn.Add(this);
Products.Add(product);
}
public virtual void AddEmployee(Employee employee)
{
employee.Store = this;
Staff.Add(employee);
}
}
}
Employee.cs：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
namespace MvcApplication1.Models.Domain
{
public class Employee
{
public virtual int Id { get; private set; }
public virtual string FirstName { get; set; }
public virtual string LastName { get; set; }
public virtual Store Store { get; set; }
}
}
Product.cs：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
namespace MvcApplication1.Models.Domain
{
public class Product
{
public virtual int Id { get; private set; }
public virtual string Name { get; set; }
public virtual double Price { get; set; }
public virtual IList<Store> StoresStockedIn { get; private set; }
public Product()
{
StoresStockedIn = new List<Store>();
}
}
}
HomeController.cs：
using System;
using System.Collections.Generic;

public ActionResult Index()
{
ViewBag.Message = "Welcome to ASP.NET MVC!";
showMe();
return View();
}
private void showMe()
{
list = new List<string>();
list.Add("test1");
list.Add("test2");
ViewBag.Output = list;
var sessionFactory = CreateSessionFactory();
using (var session = sessionFactory.OpenSession())
{
using (var transaction = session.BeginTransaction())
{
// create a couple of Stores each with some Products and Employees
var barginBasin = new Store { Name = "Bargin Basin" };
var superMart = new Store { Name = "SuperMart" };
var potatoes = new Product { Name = "Potatoes", Price = 3.60 };
var fish = new Product { Name = "Fish", Price = 4.49 };

var sue = new Employee { FirstName = "Sue", LastName = "Walkters" };
var bill = new Employee { FirstName = "Bill", LastName = "Taft" };
var joan = new Employee { FirstName = "Joan", LastName = "Pope" };
// add products to the stores, there's some crossover in the products in each
// store, because the store-product relationship is many-to-many
AddProductsToStore(barginBasin, potatoes, fish, milk, bread, cheese);
AddProductsToStore(superMart, bread, cheese, waffles);
// add employees to the stores, this relationship is a one-to-many, so one
// employee can only work at one store at a time
AddEmployeesToStore(barginBasin, daisy, jack, sue);
AddEmployeesToStore(superMart, bill, joan);
// save both stores, this saves everything else via cascading
session.SaveOrUpdate(barginBasin);
session.SaveOrUpdate(superMart);
transaction.Commit();
}
// retreive all stores and display them
using (session.BeginTransaction())
{
var stores = session.CreateCriteria(typeof(Store))
.List<Store>();
}
Console.ReadKey();
}
}
public static void AddProductsToStore(Store store, params Product[] products)
{
foreach (var product in products)
{
store.AddProduct(product);
}
}
public static void AddEmployeesToStore(Store store, params Employee[] employees)
{
foreach (var employee in employees)
{
store.AddEmployee(employee);
}
}
private static ISessionFactory CreateSessionFactory()
{
return Fluently.Configure()
.Database(MsSqlConfiguration
.MsSql2008
.ConnectionString(db => db
.FromAppSetting("testBase_db"))
/* .ShowSql()*/)
.Mappings(m => m
.FluentMappings.AddFromAssemblyOf<HomeController>()
/* .ExportTo(path)*/
)
.ExposeConfiguration(BuildSchema)
.ExposeConfiguration((c => c.Properties.Add("hbm2ddl.keywords", "none")))
.BuildSessionFactory();
}
private static void BuildSchema(Configuration config)
{
// this NHibernate tool takes a configuration (with mapping info in)
// and exports a database schema from it
new SchemaExport(config)
.SetOutputFile(@"D:\" + @"schema.sql")
.Create(true, false);
// config.Configure();
// config.AddAssembly(Assembly.LoadFrom("Restaurants24x7.NhibernateDataAccess.dll"));
// var update = new SchemaUpdate(config);
// update.Execute(true, true);
}
public ActionResult About()
{
return View();
}
}
}
在這兩條線中發生錯誤：
session.SaveOrUpdate(barginBasin);
session.SaveOrUpdate(superMart);
並且還要求它：
could not insert: [MvcApplication1.Models.Domain.Store][SQL: INSERT INTO
Store (Name) VALUES (?); select SCOPE_IDENTITY()]
其是ADOException。
幫助，請...
您是否在數據庫中創建了Store表？ – 2012-02-13 18:47:03
你有沒有找到答案？我遇到了同樣的問題。如果我解決了問題，我會在這裏發佈答案。 – 2012-05-22 03:39:32
