我正在学习Nhibernate,正在制作测试项目。我想基于实体生成表。在测试项目中,我使用sqlite并且可以看到输出:“drop table if exists Player”但是之后它不会创建表Player。我已经确认将Player.hbm.xml文件复制到另一个找到映射的文件夹中。
测试项目中的测试类:
[Test]
public void TestCanGenerateSchema()
{
var cfg = new Configuration();
cfg.Configure(); //tell NH to configure itself based on the config
cfg.AddAssembly(typeof(Player).Assembly); //find mapping info in this assembly
new SchemaExport(cfg).Execute(true, true, true);
}
测试项目中的我的Hubernate.cfg.xml:
<?xml version="1.0" encoding="utf-8" ?>
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
<session-factory>
<property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property>
<property name="dialect">NHibernate.Dialect.SQLiteDialect</property>
<property name="connection.driver_class">NHibernate.Driver.SQLite20Driver</property>
<property name="connection.connection_string">Data Source=:memory:;Version=3;New=True;</property>
<property name="connection.release_mode">auto</property>
<property name="show_sql">true</property>
<property name="proxyfactory.factory_class">NHibernate.ByteCode.Castle.ProxyFactoryFactory, NHibernate.ByteCode.Castle</property>
<!-- mapping files -->
</session-factory>
</hibernate-configuration>
我在Chess.Web项目中的映射文件(Build Action = Embedded Resource):
<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"
assembly="Chess.Web"
namespace="Chess.Web.Domain">
<class name="Player">
<id name="Id"/>
<property name="Name" />
<property name="Password" />
</class>
</hibernate-mapping>
有什么想法吗?
答案 0 :(得分:8)
new SchemaExport(cfg).Execute(true, true, true);
如果要创建表,第三个参数可能应为false:
justDrop
true if only the ddl to drop the Database objects should be executed.
