按照本教程Your first NHibernate based application学习NHibernate,我到了你打电话的地步
new SchemaExport(cfg).Execute(true, true, false);
在测试方法中导出模式(创建Product表)以验证NHibernate是否已正确设置
[Test]
public void Can_generate_schema()
{
var cfg = new Configuration();
cfg.Configure();
cfg.AddAssembly(typeof(Product).Assembly);
new SchemaExport(cfg).Execute(true, true, false);
}
映射
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="MyFirstNHibernateProject" namespace="MyFirstNHibernateProject.Domain">
<class name="Product">
<id name="Id">
<generator class="guid"></generator>
</id>
<property name="Name"></property>
<property name="Category"></property>
<property name="Discontinued"></property>
</class>
</hibernate-mapping>
配置
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
<session-factory>
<property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property>
<property name="dialect">NHibernate.Dialect.MsSqlCeDialect</property>
<property name="connection.driver_class">NHibernate.Driver.SqlServerCeDriver</property>
<property name="connection.connection_string">Data Source=MyFirstNHibernateProject.sdf</property>
<property name="show_sql">true</property>
</session-factory>
</hibernate-configuration>
测试通过,我甚至可以看到创建表的输出sql,但是没有在数据库中创建表(sql server compact),我刷新了服务器资源管理器中的数据库,它仍然是空的。
我已查看这些帖子了
NHibernate SchemaExport not creating table
NHibernate SchemaExport does not create tables when “script” is false
NHibernate does not create Tables
但他们都没有解决我的问题。
任何想法?
答案 0 :(得分:1)
我建议在连接字符串中使用完整路径:
// instead of this
<property name="connection.connection_string"
>Data Source=MyFirstNHibernateProject.sdf</property>
// we should use
<property name="connection.connection_string"
>Data Source=C:\MyFirstNHibernateProject\MyFirstNHibernateProject.sdf</property>
"C:\MyFirstNHibernateProject\"
应该是"MyFirstNHibernateProject.sdf"
另外,如果您要起诉CE 4.0,我建议使用这种方言:
<property name="dialect">NHibernate.Dialect.MsSqlCe40Dialect</property>
