NHibernate 3.2 - 现在所有属性都需要"set"方法吗？

Question

我们最近将Automapped FNH/NH项目升级到NH 3.2,并遇到了很多问题.

我们的对象模型中有很多属性,只有"getter",例如

    public virtual float Polydispersity
    {
        get { return MeasurementRun.PolyDispersity; }
    }

这曾经工作正常,但现在我们得到"找不到属性的setter"错误.

这很难找到,因为由于某种原因,自动化无法创建数据库表,导致在保存到数据库时出现"无持久性"错误 - 请参阅此处了解详细信息.

这是因为LinFu现在已经建成了NH？我知道私人制定者不再有效,这似乎也是一个类似的问题.

我们曾经使用Castle,我真的很喜欢NH现在不需要所有其他DLL,但如果它破坏了我们对象模型的很大一部分,那就不行了.

有关如何绕过这个的任何建议？

Answer 1

您不应映射只读属性.

- 解决方案1

    var map = AutoMap.AssemblyOf<Dummy>()
         .OverrideAll(x => x.IgnoreProperties(property => !property.CanWrite));

- 解决方案2

internal class MyMappingConfiguration : DefaultAutomappingConfiguration
{
        public override bool ShouldMap(Member member)
        {
            return base.ShouldMap(member) && member.CanWrite;
        }
}

...然后使用你的conf:

var map = AutoMap.AssemblyOf<Dummy>(new MyMappingConfiguration());
