<!--数据库连接池的大小-->
<property name="hibernate.connection.pool.size">20 </property>
<!--是否在后台显示Hibernate用到的SQL语句，开发时设置为true，便于差错，程序运行时可以在Eclipse的控制台显示Hibernate的执行Sql语句。项目部署后可以设置为false，提高运行效率-->
<property name="hibernate.show_sql">false </property>
<!--jdbc.fetch_size是指Hibernate每次从数据库中取出并放到JDBC的Statement中的记录条数。Fetch Size设的越大，读数据库的次数越少，速度越快，Fetch Size越小，读数据库的次数越多，速度越慢-->
<property name="jdbc.fetch_size">60 </property>
<!--jdbc.batch_size是指Hibernate批量插入,删除和更新时每次操作的记录数。Batch Size越大，批量操作的向数据库发送Sql的次数越少，速度就越快，同样耗用内存就越大-->
<property name="jdbc.batch_size">23 </property>
<!--jdbc.use_scrollable_resultset是否允许Hibernate用JDBC的可滚动的结果集。对分页的结果集。对分页时的设置非常有帮助-->
