following 2 configurations spring context file
use spring-mybatis version 1.2.0
change: change sqlsession factory read 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 mappers , let them autowired --> <bean class="org.mybatis.spring.mapper.mapperscannerconfigurer"> <property name="basepackage" value="com.comcast.triage.persistance" /> </bean>
