following two configurations into your spring context file
use spring-mybatis version 1.2.0
Change: Change your sqlSession factory to read your mappers files
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="configLocation" value="classpath:mybatis/sqlmap-config.xml" />
<property name="mapperLocations" value="classpath:mybatis/mappers/*.xml" />
</bean>
Add following entry
<!-- scan for mappers and let them be autowired -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.comcast.triage.persistance" />
</bean>
