SqlSessionFactory.openSession

SqlSessionFactory.openSession is a method used to create a new session object. A session is a connection between the application and the database that allows the application to execute SQL statements and retrieve the results.

The SqlSessionFactory is a class in MyBatis, a popular Java-based ORM (object-relational mapping) framework. It is responsible for creating sessions and managing the lifecycle of the sessions.

The openSession() method returns a new session object that can be used to interact with the database. The session object provides methods for executing SQL statements, committing or rolling back transactions, and closing the session.

Here is an example of using the openSession() method to create a new session object:

SqlSessionFactory sessionFactory = new SqlSessionFactoryBuilder().build(inputStream);
SqlSession session = sessionFactory.openSession();

In this example, the SqlSessionFactoryBuilder is used to build a SqlSessionFactory object from an input stream. The openSession() method is then called on the sessionFactory object to create a new session object. This session object can then be used to interact with the database.
