Hibernate随记

在之前接触过Hibernate，不太熟练并且一直很排斥它，认为其封装太多，不利于真正的掌握sql或数据库，又比较复杂繁琐， 一直没有很好的掌握它。最近项目要用到hibernate，没想到写了第一个例子，就出了N多错误， 随手记录一下。

1.配置Hibernate的连接池

 

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
	"-//Hibernate/Hibernate Configuration DTD 3.0//EN"
	"http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">

	</session-factory>
</hibernate-configuration>
