首先,我用谷歌搜索并在这里阅读了类似的问题,其中没有帮助。 但也许我想念一些真正重要的东西?
这里有这个教程,试图坚持下去(但也许我想念一些真正重要的东西?) http://www.infoworld.com/article/3030212/application-development/how-to-work-with-fluent-nhibernate-in-c.html
所以,继承我的NHibernate Helper:
public static class NHibernateHelper
{
public static ISession OpenSession()
{
string connectionString = ConfigurationManager.ConnectionStrings["WebAuthTest"].ConnectionString;
ISessionFactory sessionFactory = Fluently.Configure()
.Database(MsSqlConfiguration.MsSql2012.ConnectionString(connectionString).ShowSql())
.Mappings(m => m.FluentMappings.AddFromAssemblyOf<Product>())
.ExposeConfiguration(cfg => new SchemaUpdate(cfg).Execute(false, true))
.BuildSessionFactory();
return sessionFactory.OpenSession();
}
}
Web.config连接字符串:
<connectionStrings>
<add name="WebAuthTest" connectionString="data source=localhost;initial catalog=TestAuthDatabase;persist security info=True;Integrated Security=SSPI;" providerName="System.Data.SqlClient" />
</connectionStrings>
的app.config:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="NHibernate" publicKeyToken="aa95f207798dfdb4" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-4.1.0.4000" newVersion="4.1.0.4000" />
</dependentAssembly>
</assemblyBinding>
</runtime>
</configuration>
在我打电话给控制器之后,它在这里失败了:
public class TestController: ApiController
{
private readonly ITestService _testService;
public TestController()
{
}
public TestController(ITestService tst)
{
_testService = tst;
using (ISession session = NHibernateHelper.OpenSession())
{
var product = new Product { Name = "Lenovo Laptop", Description = "Sample product" };
session.SaveOrUpdate(product);
}
}
public string Get()
{
var message = string.Format("The current data on the server is: {0}", _testService.TestFunction());
return message;
}
}
堆栈追踪:
at NHibernate.Impl.SessionFactoryImpl.GetEntityPersister(String entityName)at NHibernate.Impl.SessionImpl.GetEntityPersister(String entityName, 对象obj)在 NHibernate.Event.Default.AbstractSaveEventListener.SaveWithGeneratedId(对象 entity,String entityName,Object any,IEventSource source, 布尔值requireImmediateIdAccess)at NHibernate.Event.Default.DefaultSaveOrUpdateEventListener.SaveWithGeneratedOrRequestedId(SaveOrUpdateEvent 事件) NHibernate.Event.Default.DefaultSaveOrUpdateEventListener.EntityIsTransient(SaveOrUpdateEvent 事件) NHibernate.Event.Default.DefaultSaveEventListener.PerformSaveOrUpdate(SaveOrUpdateEvent 事件) NHibernate.Event.Default.DefaultSaveOrUpdateEventListener.OnSaveOrUpdate(SaveOrUpdateEvent 事件)在NHibernate.Impl.SessionImpl.FireSave(SaveOrUpdateEvent 事件)在NHibernate.Impl.SessionImpl.Save(Object obj)
映射和模型正确,因为它们在文章中,但仍然:
public class Product
{
public virtual int Id { get; set; }
public virtual string Name { get; set; }
public virtual string Description { get; set; }
}
public class ProductMap : ClassMap<Product>
{
public ProductMap()
{
Id(x => x.Id);
Map(x => x.Name);
Map(x => x.Description);
Table("Product");
}
}
UPD :
解决。 @stuartd对该教程是正确的,它有错误
答案 0 :(得分:0)
我又太傻了。 来上班,再次用谷歌搜索。
这里的答案帮助了我:no persister for: Fluent nHibernate Exception
所以,就我而言
.Mappings(m => m.FluentMappings.AddFromAssemblyOf<ProductMap>())
解决了这个问题。
谢谢大家!
