Question

我使用NHibernate和MySQL开发了一个完整的项目。在开发和测试环境中，一切都没有了。

当我发布我的Web应用程序时，出现了很多错误。最后（我希望）和未解决（直到现在）是例外：

NHibernate.Exceptions.GenericADOException: could not execute query
[ SELECT <QUERY_HERE> ]
  Name:cp0 - Value:2012  Name:cp1 - Value:872411
[SQL: <QUERY_HERE>] ---> System.NotSupportedException: Multiple simultaneous connections or connections with different connection strings inside the same transaction are not currently supported.
   at MySql.Data.MySqlClient.MySqlConnection.Open()
   at NHibernate.Connection.DriverConnectionProvider.GetConnection()
   at NHibernate.AdoNet.ConnectionManager.GetConnection()
   at NHibernate.AdoNet.AbstractBatcher.Prepare(IDbCommand cmd)
   at NHibernate.AdoNet.AbstractBatcher.ExecuteReader(IDbCommand cmd)
   at NHibernate.Loader.Loader.GetResultSet(IDbCommand st, Boolean autoDiscoverTypes, Boolean callable, RowSelection selection, ISessionImplementor session)
   at NHibernate.Loader.Loader.DoQuery(ISessionImplementor session, QueryParameters queryParameters, Boolean returnProxies)
   at NHibernate.Loader.Loader.DoQueryAndInitializeNonLazyCollections(ISessionImplementor session, QueryParameters queryParameters, Boolean returnProxies)
   at NHibernate.Loader.Loader.DoList(ISessionImplementor session, QueryParameters queryParameters)

我创建了一个Hibernate会话管理器和一个用于WebApplication的SessinModule。 Hibernate会话是在请求开始时创建的。

我正在使用TransactionScope开始交易。

NHibernate + Mysql - System.NotSupportedException：多个同时连接
