在web开发中,可以利用hibernate配置数据源,但在实际的应用中,可能要连接多个数据源,
1.配置dataSource
bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
property name="driverClassName">
value>org.logicalcobwebs.proxool.ProxoolDriver/value>
/property>
property name="url">
value>proxool.db/value>
/property>
/bean>
2.配置sessionFactory
bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
property name="dataSource">
ref local="dataSource">/ref>
/property>
property name="hibernateProperties">
props>
prop key="hibernate.connection.provider_class"> org.hibernate.connection.C3P0ConnectionProvider/prop>
!-- 是否将运行期生成的SQL输出到日志以供调试 -->
prop key="hibernate.show_sql">true/prop>
!--指定连接的语言-->
prop key="dialect"> org.hibernate.dialect.MySQLDialect /prop>
!--是否收集有助于性能调节的统计数据-->
prop key="hibernate.generate_statistics">true/prop>
!--是否自动重新连接-->
prop key="hibernate.autoReconnect">true/prop>
!--是否自动释放连接-->
prop key="hibernate.connection.release_mode">auto/prop>
!--缓存配置-->
prop key="hibernate.cache.provider_class">org.hibernate.cache.EhCacheProvider /prop>
prop key="hibernate.cache.use_second_level_cache"> false /prop>
prop key="hibernate.cache.use_query_cache">false/prop>
/props>
/property>
property name="mappingResources">
list>
value>映射表/value>
/list>
/property>
/bean>
3.添加jdbc支持
bean id="jdbcTemplatelr" class="org.springframework.jdbc.core.JdbcTemplate">
property name="dataSource">
ref bean="dataSourceLrsql"/>
/property>
/bean>
bean id="basePageDao" class="com.BasePageDaoHibernateImpl">
property name="jdbcTemplate">
ref bean="jdbcTemplatelr"/>
/property>
/bean>
