我正在使用 ASP.Net MVC 3、spring.net 1.3.2 和 nhibernate 3.2。我一直在努力让 Web 应用程序在 IIS 7.5 中运行。它在 Visual Studio 2010 中运行良好。
我得到的错误是

我的 RepairBatchDao 的一部分是
[Repository]
class RepairBatchDAO : IRepairBatchDAO
{
public ISessionFactory SessionFactory { get; set; }
public long findRepairBatchPageCount(string login, int rowsPerPage)
{
var rowCount = 1L;
var session = SessionFactory.GetCurrentSession(); // line 55
var transaction = session.BeginTransaction();
try
{
transaction = session.BeginTransaction();
var hqlCountQuery = session.CreateQuery("select count(*) from Technolog.Rma.Business.Domain.RepairBatch rb where rb.Customer.Login=?")
.SetParameter(0, login);
rowCount = hqlCountQuery.UniqueResult<long>();
transaction.Commit();
return (rowCount + rowsPerPage - 1) / rowsPerPage;
}
catch
{
if (transaction != null) transaction.Rollback();
}
finally
{
if (session != null) session.Close(); // I shouldn't be doing this...
}
return 0L;
}
// snip ...
我花了太多时间试图自己解决这个问题。我希望有人能指出我正确的方向。我已经检查了 stackoverflow 中的各种帖子（太多了，无法提及），但它们没有帮助。
我是一个 Java 人，这是我的第一个 .net 项目，所以不确定我是否做了一些愚蠢的事情。
25/9/2012
我已经对我的 customerDAO 进行了更改
public class CustomerDAO : ICustomerDAO
{
public ISessionFactory SessionFactory { get; set; }
private TransactionTemplate tt;
public IPlatformTransactionManager TransactionManager
{
set { tt = new TransactionTemplate(value); }
}
<snip/>
public Customer find(string login)
{
IList<Customer> customers;
Object result = tt.Execute(delegate(ITransactionStatus status) //line 42
{
var transaction = status.Transaction;
var session = this.SessionFactory.GetCurrentSession();
//var transaction = session.BeginTransaction();
try
{
customers = session.CreateQuery("from Technolog.Rma.Business.Domain.Customer Customer where Customer.Login=?")
.SetParameter(0, login)
.List<Customer>();
if (customers.Count > 0)
{
return customers[0];
}
}
catch
{
}
finally
{
if (session != null) session.Close();
}
return null;
});
return (Customer)result;
}
我现在得到的错误是
