reading schema error: null

解決方法，加入

<property name="hibernate.default_schema">dbo</property>

完整的hibernate.cfg.xml如下：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-configuration SYSTEM
        "file:///E:/Download/Program/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <session-factory>
        <property name="hibernate.connection.driver_class">com.microsoft.sqlserver.jdbc.SQLServerDriver</property>
        <property name="hibernate.connection.url">jdbc:sqlserver://localhost:1433;DatabaseName=Lessonra</property>
        <property name="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</property>
        <property name="hibernate.connection.username">god</property>
        <property name="hibernate.connection.password">god</property>
        <property name="hibernate.default_schema">dbo</property>
    </session-factory>
</hibernate-configuration>

然後數據庫就能刷出來了：
