我是NHibernate 4的新手,我尝试在DB2中的两个表之间创建一对多的关系,这些表没有外键,我无法编辑表。 调试应用程序时,我在.saveorupdate方法中捕获错误。 表格包含:

在表的映射下,

它的错误 没有持久性:NHibernateExample2.NHibernateMappings.TLDMAIN
在谷歌我发现了这个错误的原因,它在映射中出错但我还没有发现这个。
感谢帮助!!!
答案 0 :(得分:1)
该错误似乎与外键问题无关。似乎NHibernate无法找到XML文件。 &#34;常见&#34;问题通常是三个:
<session-factory>
部分(通常是app.config / web.config),应该有一个<mapping assembly="NHibernateExample2"/>
(或任何带有映射的程序集)configuration.Configure()
(因为做NHibernate.Cfg.Configuration configuration = new NHibernate.Cfg.Configuration();
还不够,你必须做configuration.Configure()
)
