c# - NHibernate SchemaExport 不创建表

Question

我正在学习 Nhibernate 并正在制作一个测试项目。我想根据实体生成表格。在测试项目中，我使用的是 sqlite 并且可以看到输出:“drop table if exists Player”但之后它没有创建表 Player。我已通过将 Player.hbm.xml 文件复制到另一个文件夹来确认正在找到映射。

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);
    }

我的测试项目中的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？

Answer 1

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

如果你想创建表，第三个参数可能应该是 false:

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