nhibernate 3.0 通过 ODP.NET 连接 Oracle
有人可以告诉我下面的 nhibernate 配置有什么问题吗？使用最新的ODP.NET版本。
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2" >
<session-factory>
<property name="connection.driver_class">NHibernate.Driver.OracleDataClientDriver</property>
<property name="connection.connection_string">DATA SOURCE=Oracle2;PERSIST SECURITY INFO=True;USER ID=***;PASSWORD=*****</property>
<property name="show_sql">true</property>
<property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property>
<property name="dialect">NHibernate.Dialect.Oracle9Dialect</property>
<property name="query.substitutions">true 1, false 0, yes 'Y', no 'N'</property>
</session-factory>
</hibernate-configuration>
我收到以下错误
Error 1 Test 'ODPNETNH.Tests.GenerateSchema_Fixture.Can_generate_schema' failed: NHibernate.MappingException : Could not compile the mapping document: ODPNETNH.Mappings.Vendor.hbm.xml
----> NHibernate.HibernateException : Could not instantiate dialect class NHibernate.Dialect.Oracle9Dialect
----> System.TypeLoadException : Could not load type NHibernate.Dialect.Oracle9Dialect. Possible cause: no assembly name specified.

at NHibernate.Cfg.Configuration.AddDeserializedMapping(HbmMapping mappingDocument, String documentFileName)
at NHibernate.Cfg.Configuration.AddValidatedDocument(NamedXmlDocument doc)

Can someone tell me whats wrong with the nhibernate config below? Using the latest ODP.NET version.
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2" >
<session-factory>
<property name="connection.driver_class">NHibernate.Driver.OracleDataClientDriver</property>
<property name="connection.connection_string">DATA SOURCE=Oracle2;PERSIST SECURITY INFO=True;USER ID=***;PASSWORD=*****</property>
<property name="show_sql">true</property>
<property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property>
<property name="dialect">NHibernate.Dialect.Oracle9Dialect</property>
<property name="query.substitutions">true 1, false 0, yes 'Y', no 'N'</property>
</session-factory>
</hibernate-configuration>
I get the following error
Error 1 Test 'ODPNETNH.Tests.GenerateSchema_Fixture.Can_generate_schema' failed: NHibernate.MappingException : Could not compile the mapping document: ODPNETNH.Mappings.Vendor.hbm.xml

我在使用 NHibernate 和 Oracle (ODP.NET) 时遇到了很多问题。
最后，唯一对我有用的是引用 Oracle.DataAccess.dll 版本。 2.111，为 DLL 指定Copy Local = true。
在我的 Nhibernate 配置中，我使用了 Oracle10gDialect。
最后但并非最不重要的一点是，我使用了这种新的连接字符串样式：
I had quite a few problems working with NHibernate and Oracle (ODP.NET).
At the end the only thing which worked for me was to reference Oracle.DataAccess.dll ver. 2.111, specifying Copy Local = true for the DLL.
In my Nhibernate config I've used Oracle10gDialect.
Last but not least I've used this new connection-string style:
我想我明白了。必须调用Configure(“hibernate.cfg.xml”);
I think I figured it out. Had to call Configure("hibernate.cfg.xml");
