<!-- 扫描service下所有使用注解的类型 -->

并使用上边配置好的工厂来获取SqlSessionTemplate对象
这个对象就是openSession拿到的那个对象，可以与数据库建立会话
SqlSessionTemplate和我们openSession拿到的对象功能类似
可以声明为属性，线程安全
-->
<bean id="sqlSessionTemplate" class="org.mybatis.spring.SqlSessionTemplate">
<constructor-arg name="sqlSessionFactory" ref="sqlSessionFactory" />
<!-- 这个执行器会批量执行更新语句, 还有SIMPLE 和 REUSE -->
<!-- <constructor-arg index="1" value="BATCH" /> -->
