Creating a new SqlSession Closing non transactional SqlSession
时间: 2024-05-16 11:10:08 浏览: 32
在MyBatis中,SqlSession代表与数据库的一次会话。当我们需要执行SQL语句时,需要创建一个SqlSession对象,并在完成操作后关闭它。如果我们在一个非事务性的环境中使用SqlSession,那么我们需要在每次执行完操作后都手动关闭SqlSession。这个过程可以通过以下步骤实现:
1. 创建SqlSessionFactory对象
2. 通过SqlSessionFactory对象创建SqlSession对象
3. 执行SQL操作
4. 关闭SqlSession对象
以下是代码示例:
```
SqlSessionFactory sessionFactory = new SqlSessionFactoryBuilder().build(inputStream);
SqlSession session = sessionFactory.openSession();
try {
// 执行SQL操作
} finally {
session.close();
}
```

Closing non transactional SqlSession [org.apache.ibatis.session.defaults.DefaultSqlSession@1b2af29f] Creating a new SqlSession
Closing non transactional SqlSession means that the SqlSession object is being closed without any ongoing transaction. In the context of MyBatis, SqlSession is responsible for managing the connection with the database and executing SQL statements.
When you see the message "Closing non transactional SqlSession", it indicates that the current SqlSession is being closed after executing some SQL statements, but there was no explicit transaction started or committed. This means that the changes made in the session will not be persisted in the database.
Creating a new SqlSession means that a new instance of SqlSession is being created. This is typically done when you need to perform a new set of database operations or when you want to isolate the changes made in one session from another session.
In summary, the message indicates that a non-transactional SqlSession is being closed, and a new SqlSession is being created for further database operations.

问题: Closing non transactional SqlSession [org.apache.ibatis.session.defaults.DefaultSqlSession@44aa015e Creating a new SqlSession
回答: 这个错误信息"Closing non transactional SqlSession [org.apache.ibatis.session.defaults.DefaultSqlSession@44aa015e Creating a new SqlSession"表明你正在尝试关闭一个非事务性的SqlSession,并且尝试创建一个新的SqlSession。这种错误通常发生在SqlSession没有正确地被关闭或释放之前,又试图创建一个新的SqlSession的情况下。要解决这个问题,你需要确保在使用完SqlSession后调用close()方法来关闭它,而不是创建一个新的SqlSession。这样可以避免资源泄漏和不必要的错误。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
