Answer 1

//实例化Session
Session session = sessionFactory.openSession();
//定义事务处理对象
Transaction tx = session.beginTransaction();
上面红色的语句，编译到这里就出错了，郁闷 。看了好多网上都这样写的 
<?xml version='1.0' encoding='UTF-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
          "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
          "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <session-factory>
     <property name="show_sql">true</property>
        <property name="connection.username">sa</property>
        <property name="connection.url">jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=libSystem</property>
