MyBatis的执行过程总结

MyBatis的执行过程总结

1、配置mybatis的配置文件

2、创建SQLSessionFactory会话工厂

核心代码：

String resource = "SqlMapConfig.xml";
InputStream inputStream = Resources.getResourceAsStream(resource );
sqlSessionFactory = new SqlSessionFactoryBuilder().build(inputStream);

3、通过SqlSessioFactory创建SqlSession

SqlSession sqlSession = sqlSessionFactory.openSession();

4、调用sqlSession的方法操作数据

UserMapper usermapper = sqlSession.getMapper(UserMapper.class);

sqlSession.commit();

释放资源，关闭sqlSession

sqlSession.close();
