使用Schema-validation验证除dbo结果以外的其他模式中的休眠访问表：缺少表

Question

I have a datasource that has two schemas: dbo and example .

I've created a table in dbo schema called A , and mapped it in hibernate:

@Entity
@Table(name = "A")
public class ATable {
    private Integer id;

    @Id
    @Column(name = "id")
    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }
}

It runs without any errors as expected, I then proceeded to move the table to example schema with the following statement (runs successfully):

alter schema example transfer dbo.A

And changed the hibernate class as well:

@Entity
@Table(name = "A", schema = "example")
public class ATable {
    private Integer id;

    @Id
    @Column(name = "id")
    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }
}

But upon running it, it throws the following exception, and exit the program.

INFO: HHH000262: Table not found: A

I also tried using the following table annotation instead:

@Table(name = "example.A")

But it throws somewhat the same exception:

It seems that I need to somehow configure hibernate to support the extra schema, but don't understand how.

Application:

public class Application {
    private static SessionFactory sessionFactory;
    public static void main(String[] args) {
        Configuration configuration = new Configuration().configure();
        sessionFactory = configuration.buildSessionFactory();

        sessionFactory.openSession().close();
    }
}

And hibernate.cfg.xml

<!DOCTYPE hibernate-configuration PUBLIC
        "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
        "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

        <property name="hibernate.current_session_context_class">thread</property>

        <mapping class="com.a.A" />
    </session-factory>
</hibernate-configuration>

原来，从hibernate.cfg.xml中删除以下行可以解决问题

<property name="hibernate.hbm2ddl.auto">validate</property>
