Spring的多数据源配置(Spring+iBATIS + Oracle环境下)

在spring的配置文件上，配置两个数据源、两个事务、两个事务拦截、两个ibatis的工厂数据源配置、两个ibatis的抽象Dao。代码如下：

<?xml version="1.0" encoding="UTF-8"?>

    <!-- 事务拦截1 -->  
    <bean id="transactionInterceptor1" class="org.springframework.transaction.interceptor.TransactionInterceptor">  
        <property name="transactionManager" ref="transactionManager1" />  
        <property name="transactionAttributes">  
        <props>  
            <prop key="insert*">PROPAGATION_REQUIRED</prop>  
            <prop key="delete*">PROPAGATION_REQUIRED</prop>  
            <prop key="update*">PROPAGATION_REQUIRED</prop>

            <prop key="do*">PROPAGATION_REQUIRED</prop>  
        </props>  
        </property>  
    </bean>  
      
    <!--  管理你连接的地方-->  
    <bean id="autoProxyCreator" class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">  
        <property name="beanNames">

            <value>transactionInterceptor2</value>  
            </list>  
        </property>  
    </bean>  
      
    <!-- ibatis的工厂数据源配置1 -->  
    <bean id="sqlMapClient1" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">  
        <property name="configLocation" value="classpath:config/sql-map-config.xml" /><!--这里是ibatis的sqlMap文件集合 -->  
        <property name="dataSource" ref="dataSource1" />  
    </bean>  
      
    <!-- ibatis的工厂数据源配置2 -->  
    <bean id="sqlMapClient2" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">  
        <property name="configLocation" value="classpath:config/sql-map-config.xml" /><!--这里是ibatis的sqlMap文件集合 -->  
        <property name="dataSource" ref="dataSource2" />  
    </bean>  
      
      
  
      
    <!-- ibatis抽象的Dao1 -->  
    <bean id="baseIbatisDAO1" abstract="true">  
        <property name="sqlMapClient">  
            <ref local="sqlMapClient1" />  
        </property>  
    </bean>  
      
    <!-- ibatis抽象的Dao2 -->  
    <bean id="baseIbatisDAO2" abstract="true">  
        <property name="sqlMapClient">  
            <ref local="sqlMapClient2" />  
        </property>  
    </bean>  
</beans> 
剩下的就是spring的DAO和 service层的调用和配置了。举个例子吧：

DAO层:    

<pre class="html" name="code">    <bean id="userDAO"  
        class="org.xxx.dao.impl.UserDAOImpl"  
        parent="baseIbatisDAO1">     
    </bean>  
      
    <bean id="deptDAO"  
        class="org.xxx.dao.impl.DeptDAOImpl"  
        parent="baseIbatisDAO2">  
    </bean> 
service层（业务层）: 

<bean id="userService"  
    class="org.xxx.service.impl.UserServiceImpl"  
    parent="userDAO">     
</bean>  
  
<bean id="deptService"  
    class="org.xxx.service.impl.DeptServiceImpl"  
    parent="deptDAO">  
</bean>
