在给定的代码中,"SqlSession sqlSession = sqlSessionFactory.openSession()"是用来创建一个SqlSession实例的语句。每个线程都应该有它自己的SqlSession实例,并且SqlSession实例不是线程安全的,所以不能被共享。因此,最佳的作用域是在请求或方法级别。在你提供的代码中,它可能是在方法级别中使用的。它用于执行数据库操作,如查询用户信息、插入用户等。通过调用openSession()方法,可以获取一个SqlSession实例,然后可以使用该实例执行数据库操作。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
