在弹簧上下文文件中添加两个配置

使用spring-mybatis 1.2.0版

更改：更改sqlSession工厂以读取mappers文件

<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>

添加以下条目

<!-- scan for mappers and let them be autowired -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.comcast.triage.persistance" />
    </bean>
