hibernate中配置多个数据库
1
创建多个hibernate.cfg.xml文件名字要不一样具体内容如下:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE hibernate-configuration
PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN"
"http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
<session-factory >
<!-- 数据库联接配置 -->
<property name="connection.username">root</property>
<property name="connection.password">12345</property>
<property name="connection.url">jdbc:mysql://localhost:3306/xinli?useUnicode=true&characterEncoding=utf-8</property>
<property name="dialect">org.hibernate.dialect.MySQLDialect</property>
<property name="connection.driver_class">com.mysql.jdbc.Driver</property>
<!--显示SQL语句-->
<property name="show_sql">true</property>
<!-- 数据表对应的映射文件 -->
<mapping resource="com/sky/dto/User.hbm.xml" />
<mapping resource="com/sky/dto/Columnt.hbm.xml" />
<mapping resource="com/sky/dto/Textcontent.hbm.xml" />
<mapping resource="com/sky/dto/Product.hbm.xml" />
<mapping resource="com/sky/dto/ProductType.hbm.xml" />
<mapping resource="com/sky/dto/News.hbm.xml" />
</session-factory>
</hibernate-configuration>
现创建2个示例:
hibernate.cfg.xml,hibernate.en.xml
2 在applicationContext.xml里配置hibernate.cfg.xml等,内容如下:
<beans>
<!--定义Hibernate的SessionFactory-->
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="configLocations">
<value>/WEB-INF/hibernate.cfg.xml</value>
</property>
</bean>
<!--定义Hibernate en的SessionFactory-->
<bean id="sessionFactoryen" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="configLocations">
<value>/WEB-INF/hibernate.en.xml</value>
</property>
</bean>
</beans>
3 在spring配置中配置对应的sessionFactory
