Hibernate加载其数据库配置
Hibernate加载其配置文件hibernate.properties和hibernate.cfg.xml,常用xml文件比较直观，方便管理，Hibernate是一个流行的开源对象关系映射工具，方便连接不同数据库，更换数据库，只要修改Hibernate配置文件，大度减少项目的维护。完整的配置如下:
<div style="border: 1px solid #cccccc; padding: 4px 5px 4px 4px; background-color: #eeeeee; font-size: 13px; width: 98%;"><!----><?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>
<!-- Database connection settings -->
<property name="connection.driver_class">org.hsqldb.jdbcDriver</property>
<property name="connection.url">jdbc:hsqldb:hsql://localhost/test</property>
<property name="connection.username">sa</property>
<property name="connection.password"></property>
<!-- JDBC connection pool (use the built-in) -->
<property name="connection.pool_size">1</property>
<!-- SQL dialect -->
<property name="dialect">org.hibernate.dialect.HSQLDialect</property>
<!-- Enable Hibernate's automatic session context management -->
