单数据路径配置
<bean id="sqlSessionFactory2" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource2" />
<property name="mapperLocations" value="classpath*:com/loongshawn/dao/impl/mapper2/pmp/*.xml" />
<property name="typeAliasesPackage" value="com.autonavi.domain" />
</bean>
<!-- mybatis.spring自动映射 -->
<bean id="mybatisMapperScanner2" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.loongshawn.pmp" />
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory2" />
</bean>
多数据路径配置
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="mapperLocations">
<array>
<value>classpath:com/loongshawn/dao/impl/mapper/*.xml</value>
<value>classpath:com/loongshawn/dao/impl/mapper3/pmc/*.xml</value>
</array>
</property>
<property name="typeAliasesPackage" value="com.autonavi.domain" />
</bean>
<!-- mybatis.spring自动映射 -->
<bean id="mybatisMapperScanner" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.loongshawn.dao.impl.mapper,com.loongshawn.dao.impl.mapper3" />
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
</bean>
<mark>mapperLocations</mark>属性多路径配置如下：
<property name="mapperLocations">
<array>
<value>classpath:com/autonavi/dao/impl/mapper/*.xml</value>
<value>classpath:com/autonavi/dao/impl/mapper3/pmc/*.xml</value>
</array>
</property>
basePackage属性多路径配置仅需通过英文逗号”,”分隔开不同路径即可。
以上实现方式均验证无误。
