NHibernate无法解析属性

我得到例外NHibernate.QueryException:无法解决财产问题:InsuredId.我是NHibernate的新手,我无法理解.

定义属性

public virtual int InsuredId { get; set; }
public virtual string Gender { get; set; }
public virtual DateTime DateOfBirth { get; set; }
public virtual string SrId { get; set; }
public virtual string SchoolId { get; set; }
public virtual string Ssn { get; set; }
public virtual DateTime GradDate { get; set; }

将数据映射到属性

public InsuredMap()
{
     ReadOnly();

     Table("Insured");
     Id(x => x.Id, "InsuredId");
     Map(x => x.Gender, "SexCd");
     Map(x => x.DateOfBirth, "BirthDt");
     Map(x => x.SrId, "SIDIdNum");
     Map(x => x.SchoolId, "SchoolIdTxt");
     Map(x => x.Ssn, "SocSecNumTxt");
     Map(x => x.GradDate, "GradMthYrNum");
}

获取所有值的函数

public Entities.Insured GetByInsuredId(int insuredId)
{
    var query = Session.QueryOver()
        .Where(x => x.InsuredId == insuredId)
        .Cacheable()
        .CacheRegion(Constants.EntityCacheRegion);

    return query.SingleOrDefault();
}

单元测试以测试数据

[Test]
public void InsuredMapTest()
{
    var insured = repository.GetByInsuredId(714619800);
    Assert.That(insured.Gender, Is.EqualTo("F"));
}

让我更准确一点,并扩展安德鲁惠特克的评论.

在您所说的映射中:

Id(x => x.Id, "InsuredId");

哪个是信息:我的实体/班级Insured有

Id(            // an identificator, the key
x => x.Id      // represented by the property **Id** (here is the issue)
, "InsuredId") // its DB representation is the column "InsuredId"

换句话说,C#属性

public virtual int InsuredId { get; set; }

是不映射,在上述语句,所以它不能被用于查询

我们在查询中可以做些什么才能使它工作

var query = Session.QueryOver()
    //.Where(x => x.InsuredId == insuredId)
    .Where(x => x.Id == insuredId)
    ...

并且无法解析属性:InsuredId异常将消失,因为我们正在使用映射属性Id
