我使用ISession.CreateSQLQuery
调用存储过程。
然后我用
SetResultTransformer(new AliasToBeanResultTransformer(typeof(Article))).List<Article>().ToList()
此方法的问题在于AliasToBeanResultTransformer
仅将Article
表一对一地映射到Article
类。
public class Article : Entity
{
public virtual string Description { get; set; }
}
public class Entity
{
public virtual int Id { get; set; }
}
public class ArticleRepository : Repository<Article>, IArticleRepository
{
private ISession _session;
public ArticleRepository(ISession session) : base(session)
{
_session = session;
}
public List<Article> GetByDescription(string description)
{
return _session
.CreateSQLQuery("EXEC ArticlesByDescription :Description")
.SetString("Description", description)
.SetResultTransformer(new AliasToBeanResultTransformer(typeof(Article)))
.List<Article>().ToList();
}
}
但我的Article
表上的主键名为ArticleId
,因此AliasToBeanResultTransformer
会抛出异常。
无法在课程中找到属性'ArticleId'的setter 'Core.DomainModels.Article'
使用CreateSqlQuery
时有没有办法重用FluentNhibernateMapping?
编辑:
Nhibernate Documentation描述了如何将已映射的实体与hbm文件一起使用。
<sql-query name="GetProductsByCategoryId">
<return class="Product" />
exec dbo.GetProductsByCategoryId :CategoryId
</sql-query>
我真的问自己为什么不能仅通过代码来做到这一点?!

似乎无法使用ISession.CreateSQLQuery
并从ISession
获取映射的实体。
我现在所做的是将hbm文件和FluentNhibernate映射一起使用。
HBM:
<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="Core" namespace="Core.DomainModels">
<sql-query name="ArticlesByDescription">
<return class="Article" />
EXEC ArticlesByDescription :Description
</sql-query>
</hibernate-mapping>
FluentNhibernate:
public class ArticleMapping : ClassMap<Article>
{
public ArticleMapping()
{
Id(x => x.ArticleId).GeneratedBy.Identity();
Map(x => x.Description).UniqueKey("Article_Description_Unique");
}
}
配置:
public class ConfigurationFactory
{
const string Database = "";
const string Server = "";
public static Configuration Build()
{
return Fluently.Configure()
.Database(MsSqlConfiguration.MsSql2008.ConnectionString(
c => c.Database(Database).TrustedConnection().Server(Server)))
.Mappings(m =>
{
m.FluentMappings.AddFromAssemblyOf<ArticleMapping>();
m.HbmMappings.AddFromAssemblyOf<ArticleMapping>();
})
//.ExposeConfiguration(c => new SchemaExport(c).Execute(true, true, false))
.BuildConfiguration();
}
}
存储库:
public class ArticleRepository : Repository<Article>, IArticleRepository
{
private ISession _session;
public ArticleRepository(ISession session) : base(session)
{
_session = session;
}
public List<Article> GetByDescription(string description)
{
return _session
.GetNamedQuery("ArticlesByDescription")
.SetString("Description", description)
.List<Article>().ToList();
}
}

我正在使用此代码映射到存储库中的实体。我相信它也适用于调用程序:
public IEnumerable<Address> Search(string query, int maxCount)
{
return session.CreateSQLQuery("SELECT * FROM address WHERE fts_col @@ plainto_tsquery('cs', :query) LIMIT :limit;")
.AddEntity(typeof(Address)) // this is probably what you need to map to entity
.SetString("query", query)
.SetInt32("limit", maxCount)
.List<Address>();
}
