Question

springmybatis动态数据源

Answer 1

<bean id="dynamicSqlSessionDaoSupport" class="com.yunat.channel.common.DynamicSqlSessionDaoSupport">  
        <property name="targetSqlSessionFactorys">  
            <map value-type="org.apache.ibatis.session.SqlSession">  
                <entry key="channel" value-ref="sqlSessionFactory_channel" /> 
                <entry key="custom" value-ref="sqlSessionFactory_custom" />  
                <entry key="ucenter" value-ref="sqlSessionFactory_ucenter" />  
            </map>
        </property>  
        <property name="defaultTargetSqlSessionFactory" ref="sqlSessionFactory_channel" />  
    </bean>我的applicationContext.xml里面是这样配置的，启动时候tomcat报错，查不出原因
