對通用接口Mapper的實例化放到DAO接口所在包後面
<!-- DAO接口所在包名，Spring會自動查找其下的類 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.dao" />
</bean>
<!-- 對通用接口Mapper的實例化(如果沒有,只能調用自己的Mapper接口的方法,不能使用通用Mapper接口的方法) -->
<bean class="tk.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.isea533.mybatis.mapper" />
<property name="properties">
<value>
mappers=tk.mybatis.mapper.common.Mapper
</value>
</property>
