一、框架架构
1、先初始化SqlSessionFactory对象:
MyBatis(8)——运行原理-初始化SqlSessionFactory
2、使用sqlSessionFactory对象获取SqlSession对象:
MyBatis(9)——运行原理-获取SqlSession对象
3、使用SqlSession的getMapper方法获取接口的代理对象:
MyBatis(10)——运行原理-getMapper获取接口的代理对象
4、最后调用mapper的查询方法:
MyBatis(11)——运行原理-查询流程原理
二、运行原理
@Test public void testInterface() throws IOException { String resource = "mybatis-config.xml"; InputStream inputStream = Resources.getResourceAsStream(resource); SqlSessionFactory sqlSessionFactory = new SqlSessionFactoryBuilder().build(inputStream); SqlSession session = sqlSessionFactory.openSession(); try { EmployeeMapper mapper = session.getMapper(EmployeeMapper.class); Employee employee = mapper.selectEmployee(121); System.out.println(employee); } finally { session.close(); } }
