/**
* 参考：https://github.com/mybatis/spring/blob/master/src/main/java/org/mybatis/spring/SqlSessionFactoryBean.java
*
* 在 MyBatis 官方的 SqlSessionFactoryBean 基础上,替换了 FlexSqlSessionFactoryBean。
*
*
源于 {@link SqlSessionFactoryBean}，主要是用于构建 {@link com.mybatisflex.core.mybatis.FlexConfiguration }，而不是使用原生的 {@link Configuration}。
*
*
此代码主要是用于修改 {@link FlexSqlSessionFactoryBean#buildSqlSessionFactory()} 部分。
