NHibernate SchemaExport not creating table

问题

I'm learning Nhibernate and am making a test project. I want to generate tables based on the entities. In the test project, I am using sqlite and can see the output: "drop table if exists Player" but it's not creating the table Player afterwards. I have confirmed by copying the Player.hbm.xml file into another folder that the mapping is being found.

Test class in the test project:

    [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);
    }

My Hubernate.cfg.xml in the test project:

<?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>

My mapping file in Chess.Web project (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>

Any ideas?

回答1:

new SchemaExport(cfg).Execute(true, true, true);

Third parameter should probably be false if you want to create tables:

justDrop
true if only the ddl to drop the Database objects should be executed.
