[英]Nhibernate: invoke stored procedure with CreateSqlQuery using already defined mapping
I Invoke a stored procedure using ISession.CreateSQLQuery
. 我使用ISession.CreateSQLQuery
调用存储过程。
Then I use 然后我用
SetResultTransformer(new AliasToBeanResultTransformer(typeof(Article))).List<Article>().ToList()
The problem with this approach is that the AliasToBeanResultTransformer
only maps the Article
table to the Article
class one to one. 此方法的问题在于AliasToBeanResultTransformer
仅将Article
表AliasToBeanResultTransformer
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();
}
}
But my primary key on my Article
table is called ArticleId
, so that the AliasToBeanResultTransformer
throws an exception. 但是我的Article
表上的主键叫做ArticleId
,因此AliasToBeanResultTransformer
会抛出异常。
Could not find a setter for property 'ArticleId' in class 'Core.DomainModels.Article' 无法在“Core.DomainModels.Article”类中找到属性“ArticleId”的setter
Is there a way of reusing the FluentNhibernateMapping when using CreateSqlQuery
? 有没有使用时重用FluentNhibernateMapping的方式CreateSqlQuery
?
EDIT: 编辑:
The Nhibernate Documentation describes how you can use an already mapped entity with hbm files. Nhibernate文档描述了如何使用已映射的实体和hbm文件。
<sql-query name="GetProductsByCategoryId">
<return class="Product" />
exec dbo.GetProductsByCategoryId :CategoryId
</sql-query>
I really ask myself why is it not possible to do this just by code?! 我真的问自己为什么不能通过代码来做到这一点?!
It seems not possible to use ISession.CreateSQLQuery
and get a mapped entity back from the ISession
. 这似乎不可能使用ISession.CreateSQLQuery
,并得到一个映射实体从后面ISession
。
What I do for now is using hbm files and FluentNhibernate mappings together. 我现在要做的是将hbm文件和FluentNhibernate映射一起使用。
Hbm: 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: FluentNhibernate:
public class ArticleMapping : ClassMap<Article>
{
public ArticleMapping()
{
Id(x => x.ArticleId).GeneratedBy.Identity();
Map(x => x.Description).UniqueKey("Article_Description_Unique");
}
}
Configuration: 组态:
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();
}
}
Repository: 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();
}
}
I am using this code for mapping to entity in repository. 我正在使用此代码映射到存储库中的实体。 I believe it would work for calling procedure also: 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>();
}
