NH枚举实体枚举值存为字串

NH枚举实体枚举值存为字串

前言:枚举值存默认我们知道保存是整形,实际上这是没有什么意义的,如何让其有意义呢?

那么就将其保存为字串吧,下面的步骤用nh3慢慢将其实现

1:实体(程序集为Eg.Core)

public enum AccountTypes

    {

        Consumer,

        Business,

        Corporate,

        NonProfit

    }

 

    public class Account

    {

        public virtual Guid Id { get; set; }

        public virtual AccountTypes AcctType { get; set; }

        public virtual string Number { get; set; }

        public virtual string Name { get; set; }

}

2:映射

<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"

    assembly="Eg.Core"

    namespace="Eg.Core">

  <class name ="Account">

  <id name="Id">

    <generator class="guid.comb" />

  </id>

  <natural-id>

    <property name="Number" not-null="true"  />

  </natural-id>

  <property name="Name" not-null="true" />  

    <!--关键地方注意type类型-->

  <property name="AcctType" not-null="true"

             type="NHibernate.Type.EnumStringType`1[[Eg.Core.AccountTypes, Eg.Core]], NHibernate"

            />

  </class>

</hibernate-mapping>

3:其他配置略

4:单元测试

[Test]

        public void CreateAccount()

        {

            //save

            NHibernateHelper.BeginTransaction();

            Account ac = new Account()

            {

                AcctType = AccountTypes .Corporate  ,

                Name ="abcName",

                Number ="210403033"

            };

            NHibernateHelper.Session.Save(ac);

            NHibernateHelper.CommitTransaction();

            NHibernateHelper.CloseSession();

       

            //load

            Account acGet=NHibernateHelper.Session.Get<Account>(ac.Id);

            Console.WriteLine("AcctType(int):" + (int)acGet.AcctType + "; AcctType(str)"+acGet .AcctType );

        }

结果显示:

AcctType(int):2; AcctType(str)Corporate
