C# Nhibernate IsessionFactory的统一Xml配置
我使用代码解析了会话工厂C# Nhibernate IsessionFactory的统一Xml配置,c#,nhibernate,unity-container,xml-configuration,C#,Nhibernate,Unity Container,Xml Configuration,我使用代码解析了会话工厂 UnityContainer.RegisterInstance(typeof(ISessionFactory), new NHibernate.Cfg.Configuration().Configure().BuildSessionFactory()); 我的服务,它将属性定义为 public class myService { [Dependency] public ISessionFactory SessionFacto
UnityContainer.RegisterInstance(typeof(ISessionFactory),
new NHibernate.Cfg.Configuration().Configure().BuildSessionFactory());
我的服务,它将属性定义为
public class myService
{
[Dependency]
public ISessionFactory SessionFactory{get;set;}
}
但是我不知道如何使用unity 2的XML配置来配置它。免责声明,这个答案与这里讨论的内容(注释)更相关 让我为您提供更多有关映射的详细信息 首先,减少全名:
// here we have namespace, not needed below for classes, if is the same
<hibernate-mapping ... namespace="NhibernateTesting.Models" >
//这里有名称空间,下面的类不需要名称空间,如果名称空间相同
对原始类映射进行了注释,我的方法是替换它:
// <class name="NhibernateTesting.Models.ProductList" table="ProductList" lazy="false">
<class name="ProductList" table="ProductList"
lazy="true" // always use LAZY
batch-size="25" // optimization for loading - avoid 1 + N
>
//<id name="Id">
// <generator class="native" />
//</id>
// more readable version
<id name="Id" generator="native" />
// these are OK
<property name="Name" />
<property name="Owner" />
// collection should be ALWAYS lazy
// <bag name="Viewers" table="ProductListViewer" lazy="false">
// and also, optimization as batch size is needed
<bag name="Viewers" table="ProductListViewer"
lazy="true" // LAZY is must,
batch-size="25" cool optimization to avoid 1 + N
>
<key column="ProductListId" />
<element column="Username" type="System.String"/>
</bag>
// I would never use MANY-TO-MANY
// <bag name="Products" table="ProductListProductXRef" lazy="false" cascade="all" fetch="select">
<bag name="Products" table="ProductListProductXRef"
inverse="true" // in many to many only one side could be inverse
lazy="true"
cascade="none" // cascade here means, delete PRODUCTS
// not the pairing table, so I would expect that we need none
fetch="select">
<key column="ProductListId" />
// I would avoid many to many if possible
<many-to-many column="ProductId" class="NhibernateTesting.Models.Product" />
...
//
//
//
//
//更具可读性的版本
//这些没问题
//集合应该总是懒惰的
//
//此外,还需要根据批量大小进行优化
//我永远不会用多对多的方式
//
//如果可能的话,我会避免多对多

懒惰
<class
name="ProductList"
table="ProductList"
lazy="true"
batch-size="25"
>
如果我们需要版本控制:
<class
name="ProductList"
table="ProductList"
lazy="true"
batch-size="25"
optimistic-lock="version"
dynamic-update="true"
>
<version name="Timestamp" generated="always" unsaved-value="null" type="BinaryBlob">
<column name="RowVersion" not-null="false" sql-type="timestamp"/>
</version>
这应该是集合映射:
<bag name="Items"
lazy="true"
inverse="true"
batch-size="25"
cascade="all-delete-orphan">
<key column="Item_ID" />
<one-to-many class="SomeItemClass"/>
</bag>
