2.1、批量插入操作

    <!--配置一个可以执行批量的sqlSession-->
    <bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate">
        <!--
                SqlSessionTemplate 中的 有参构造方法：
                public SqlSessionTemplate(SqlSessionFactory sqlSessionFactory, ExecutorType executorType) {-->
        <!--引入，注入sqlSessionFactory-->
        <constructor-arg name="sqlSessionFactory" ref="sqlSessionFactory"/>
        <!--
        ExecutorType executorType：执行类型，
         value="BATCH"：批量处理
         -->
        <constructor-arg name="executorType" value="BATCH"/>
    </bean>
