Question

在中等信任環境中使用Unity +功能NHibernate NHibernate的+ 3.3.1.4

var session = sessionFactory.OpenSession(); 

這個錯誤：

有人能幫助我嗎？

Answer 1

這是一個很容易解決的問題。您必須禁用批處理。您可以通過設置屬性adonet.batch_size這樣做是爲了0

在App.config/Web.config您hibernate.cfg.xml或NHibernate的配置部分：

<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2"> 
    <reflection-optimizer use="false"/> 
    <session-factory> 
    <!-- other properties --> 
    <property name="adonet.batch_size">0</property> 
    </session-factory> 
</hibernate-configuration> 

或者通過FluentNHibernate：

var db = MsSqlConfiguration.MsSql2008 
    // other configurations 
    .AdoNetBatchSize(0); 

return Fluently.Configure() 
    // other configurations 
    .Database(db) 
    .BuildConfiguration();
