没有通过数据库方法配置流利的NHibernate数据库

本文关键字:数据库 NHibernate 配置 方法 | 更新日期: 2023-09-27 18:05:30

我从Fluent开始。我的c# web项目已经正确使用了NHibernate,现在我想迁移到Fluent。

当我尝试做一个配置请求时,我收到错误:

创建时使用了无效或不完整的配置SessionFactory。检查PotentialReasons集合和InnerException查看详细信息。

  • 没有通过数据库方法配置数据库。

插入PotentialReason属性,我看到:

没有通过数据库方法配置数据库。

into InnerException into InnerException (xD) i see:

composite-id类必须重写Equals():

但当我从Fluent到NHibernate(使用经典hbm文件,不改变配置类),我没有看到任何问题…所以问题发生时,我使用Fluent库。

当代码尝试执行这个指令时出现错误:

this._sessionFactory = this._configuration
                .Mappings(m => m.FluentMappings.AddFromAssemblyOf<TIdentifier>())
                .BuildSessionFactory();

目前我只尝试迁移一个实体(Config.cs),这是我的实体:

public class ConfigKey : BaseKey
{
    public virtual string id { get; set; }
    public ConfigKey() : base()
    {
        if(this.userId == null)
        {
            this.userId = "SYSTEM";
        }
    }
    #region OVERRIDES
    public override bool Equals(object obj)
    {
        if(obj != null)
        {
            ConfigKey _key = obj as ConfigKey;
            if(_key == null)
            {
                return false;
            }
            if(_key.id == this.id && _key.applicationId == this.applicationId && _key.id == this.id)
            {
                return true;
            }
        }
        return false;
    }
    public override int GetHashCode()
    {
        return (this.id.ToString() + "|" + this.applicationId.ToString() + "|" + this.id)
            .GetHashCode();
    }
    #endregion
}
public class Config : BaseEntity<ConfigKey>
{
    public virtual string value { get; set; }
    public virtual string description { get; set; }
    #region CONSTRUCTORS
    public Config() { }
    public Config(ConfigKey key)
    {
        this.key = key;
    }
    #endregion
}
public abstract class BaseKey
{
    public virtual Guid applicationId { get; set; }
    public virtual string userId { get; set; }
    public virtual bool isNew
    {
        get
        {
            bool test = false;
            Dictionary<string, ObjectDefinition> transposed = this.Transpose();
            foreach (KeyValuePair<string, ObjectDefinition> property in transposed)
            {
                if (property.Value.Value == null)
                {
                    test = true;
                    break;
                }
                else if (property.Value.Default != null && (property.Value.Value.ToString() == property.Value.Default.ToString()))
                {
                    test = true;
                    break;
                }
            }
            return test;
        }
    }
    public BaseKey()
    {
        this.applicationId = BaseContext.getContext.applicationId;
        try
        {
            //if exists a user context, take the user id
            this.userId = BaseContext.getContext.user.key.id;
        }
        catch
        {
            //else user id is not setted
            this.userId = null;
        }
    }
    #region OVERRIDES
    public override bool Equals(object obj)
    {
        if (obj != null)
        {
            BaseKey _key = obj as BaseKey;
            if (_key == null)
            {
                return false;
            }
            if (_key.applicationId == this.applicationId && _key.userId == this.userId)
            {
                return true;
            }
        }
        return false;
    }
    public override int GetHashCode()
    {
        return (this.applicationId.ToString() + "|" + this.userId)
            .GetHashCode();
    }
    #endregion
}

和map类如下(Config和ConfigMap在同一个命名空间和同一个程序集中):

public class ConfigMap : ClassMap<Config>
{
    public ConfigMap()
    {
        Schema("dbo");
        Table("CONFIG");
        CompositeId()
            .KeyProperty(x => x.key.applicationId, "APPLICATION_ID")
            .KeyProperty(x => x.key.userId, "USER_ID")
            .KeyProperty(x => x.key.id, "ID");
        Map(x => x.description, "DESCRIPTION");
        Map(x => x.value, "VALUE");
    }
}

和这是SessionFactory(我用它为经典的NHibernate,我已经创建了这个新的命名空间为Fluent):

public class NHibernateHelper<TIdentifier> where TIdentifier : class
{
    ISessionFactory _sessionFactory;
    FluentConfiguration _configuration;
    private ISessionFactory SessionFactory
    {
        get
        {
            if (this._sessionFactory == null)
            {
                if(this._configuration == null)
                {
                    this._configuration = Fluently.Configure();
                }
                this._sessionFactory = this._configuration
                    .Mappings(m => m.FluentMappings.AddFromAssemblyOf<TIdentifier>())
                    .BuildSessionFactory();
            }
            return this._sessionFactory;
        }
    }
...
}

进入我的网络。配置我已经留下了相同的我使用的NHibernate:

  <!-- NHibernate configuration -->
  <hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
    <session-factory name="it.quasar.NHibernate">
      <property name="connection.driver_class">NHibernate.Driver.SqlClientDriver</property>
      <!--roperty name="connection.driver_class">NHibernate.Driver.OleDbDriver</property-->
      <property name="dialect">NHibernate.Dialect.MsSql2008Dialect</property>
      <property name="connection.connection_string_name">lollo</property>
      <property name="show_sql">true</property>
    </session-factory>
  </hibernate-configuration>
我需要你的帮助。我的代码有什么问题?我能做些什么来纠正我的代码?

非常感谢大家!:)

问题是映射,你在用KeyProperty映射组合键这总是会抛出错误,用KeyReference代替,这应该是完美的

CompositeId()
   .KeyReference(x => x.key.applicationId, "APPLICATION_ID")
   .KeyReference(x => x.key.userId, "USER_ID")
   .KeyReference(x => x.key.id, "ID");
