All Implemented Interfaces:

public class MapperFactoryBean<T> extends SqlSessionDaoSupport implements org.springframework.beans.factory.FactoryBean<T>
BeanFactory that enables injection of MyBatis mapper interfaces. It can be set up with a SqlSessionFactory or a pre-configured SqlSessionTemplate.

Sample configuration: 

 
   <bean id="baseMapper" class="org.mybatis.spring.mapper.MapperFactoryBean" abstract="true" lazy-init="true">
     <property name="sqlSessionFactory" ref="sqlSessionFactory" />
   </bean>

   <bean id="oneMapper" parent="baseMapper">
     <property name="mapperInterface" value="my.package.MyMapperInterface" />
   </bean>

   <bean id="anotherMapper" parent="baseMapper">
     <property name="mapperInterface" value="my.package.MyAnotherMapperInterface" />
   </bean>

Note that this factory can only inject interfaces, not concrete classes.
