我是 Fluent NHibernet 的新手，我在我的 asp.net 应用程序中使用 Fluent NHibernet
这是我的 Poco 课
public virtual int CategoryId { get; set; }
public virtual string CategoryName { get; set; }
public virtual bool IsActive { get; set; }
public virtual bool IsDeleted { get; set; }
我的映射类
public class clsCategoryMap : ClassMap<clsCategory>
{
public clsCategoryMap()
{
Id(x => x.CategoryId).Column("CategoryId").GeneratedBy.Assigned().Not.Nullable();
Map(x => x.CategoryName).Column("CategoryName").Not.Nullable();
Map(x => x.IsActive).Column("IsActive").Not.Nullable();
Map(x => x.IsDeleted).Column("IsDeleted").Not.Nullable();
Table("tblCategory");
}
}
Poco 类和 Mapping 类都在 Liberar 类中分离，例如：DAL 用于 Poco 类，BLL 用于 Mapping 类。
我创建了助手类，它在下面：
public class FNHelper
{
private static ISessionFactory _sessionfactory;
private static ISessionFactory SessionFactory
{
get
{
if (_sessionfactory == null) { InitializationSessionFactory(); }
return _sessionfactory;
}
}
private static void InitializationSessionFactory()
{
_sessionfactory = Fluently.Configure()
.Database(
MsSqlConfiguration.MsSql2008
.ConnectionString(@"Server=test\SQLEXPRESS;Database=TestDB;User ID=sa;Password=root;")
.DefaultSchema("dbo")
.ShowSql()
)
.Mappings(m => m.FluentMappings.AddFromAssemblyOf<clsCategory>())
.ExposeConfiguration((cfg => new SchemaUpdate(cfg).Execute(true, true)))
.BuildSessionFactory();
}
public static ISession OpenSession()
{
return SessionFactory.OpenSession();
}
private static void BuildSchema(NHibernate.Cfg.Configuration configuration)
{
String SqliteRefFileName = @"D:\Projects\MeshpsDB.sql";
if (File.Exists(SqliteRefFileName))
File.Delete(SqliteRefFileName);
new SchemaExport(configuration)
.Create(true, true);
}
}
最后我以我的形式在下面做：
protected void btnSave_Click(object sender, EventArgs e)
{
using (var session = FNHelper.OpenSession())
{
using (var tranction = session.Transaction)
{
var objCategory = new clsCategory
{
CategoryId = 0,
CategoryName = txtName.Text.Trim(),
IsActive = true,
IsDeleted = false
};
session.Save(objCategory);
tranction.Commit();
}
}
}
当我点击按钮时，我得到了
所以每个人都请告诉我我该如何解决这个问题。
