java - Spring 3 + MyBatis 3

Question

spring 3和mybatis 3如何创建多个连接数据库。我需要同时连接MySQL和Oracle。你能帮助我吗？

Answer 1

每个数据库需要 1 个 SqlSessionFactory。

<bean id="db1SqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="configLocation" value="classpath:sqlmap1.xml"/>
    <property name="dataSource" ref="db1datasource"/>
</bean>

<bean id="db2SqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="configLocation" value="classpath:sqlmap2.xml"/>
    <property name="dataSource" ref="db2datasource"/>
</bean>

<bean id="db1SqlSession" class="org.mybatis.spring.SqlSessionTemplate">
    <qualifier value="db1" />
    <constructor-arg index="0" ref="db1SqlSessionFactory" />
</bean>


<bean id="db2SqlSession" class="org.mybatis.spring.SqlSessionTemplate">
    <qualifier value="db2" />
    <constructor-arg index="0" ref="db2SqlSessionFactory" />
</bean>
