用Hibernate配置连接数据库可以方便我们对POJO的操作,节省了很多时间和代码。下面就分别说明连接不同数据库需要在hibernate.cfg.xml做的配置。

1、Hibernate连接MySQL数据库的hibernate.cfg.xml
1 <?xml version='1.0' encoding='UTF-8'?>
2 <!DOCTYPE hibernate-configuration PUBLIC
3 "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
4 "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
5 <!-- Generated by MyEclipse Hibernate Tools. -->
6 <hibernate-configuration>
7 <session-factory>
8 <!-- 配置JDBC连接属性 -->
9 <property name="myeclipse.connection.profile">
10 com.mysql.jdbc.Driver
11 </property>
12 <property name="connection.url">
13 jdbc:mysql://localhost:3306/basehibernate
14 </property>
15 <property name="connection.username">root</property>
16 <property name="connection.password">sa</property>
17 <property name="connection.driver_class">
18 com.mysql.jdbc.Driver
19 </property>
20 <property name="dialect">
21 org.hibernate.dialect.MySQLDialect
22 </property>
23
24 <!-- 自动建表 -->
25 <property name="hbm2ddl.auto">update</property>
26 <!-- 自动提交,不加的话可能会出现insert之后数据库无数据 -->
27 <property name="connection.autocommit">true</property>
28
29 <!-- 使用Hibernate Annotation的POJO类 -->
30 <mapping class="com.basehibernate.pojo.Department" />
31 <mapping class="com.basehibernate.pojo.Employee" />
32 </session-factory>
33 </hibernate-configuration>
2、Hibernate连接Oracle数据库的hibernate.cfg.xml
1 <?xml version='1.0' encoding='UTF-8'?>
2 <!DOCTYPE hibernate-configuration PUBLIC
3 "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
4 "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
5 <!-- Generated by MyEclipse Hibernate Tools. -->
6 <hibernate-configuration>
7 <session-factory>
8 <!-- 配置JDBC连接属性 -->
9 <property name="connection.driver_class">
10 oracle.jdbc.driver.OracleDriver
11 </property>
12 <property name="connection.url">
13 jdbc:oracle:thin:@localhost:1521:chanshuyi
14 </property>
15 <property name="myeclipse.connection.profile">oracle</property>
16 <property name="connection.username">csy</property>
17 <property name="connection.password">csy</property>
18 <property name="dialect">org.hibernate.dialect.Oracle9Dialect</property>
19
20 <!-- oracle特有的提交更改 -->
21 <property name="defaultAutoCommit">true</property>
22 <!-- 自动建表 -->
23 <property name="hbm2ddl.auto">auto</property>
24 <property name="show_sql">true</property>
25 <!-- 自动提交,不加的话可能会出现insert之后数据库无数据 -->
26 <property name="connection.autocommit">true</property>
27
28 <!-- 使用Hibernate Annotation的POJO类 -->
29 <mapping class="com.xinpinv.pojo.Product" />
30 <mapping class="com.xinpinv.pojo.BitInfo" />
31 </session-factory>
32 </hibernate-configuration>
