Mybatis注解开发使用二级缓存

 @Test
    public void testFindOne() {

        SqlSession session = factory.openSession();
        IUserDao userDao = session.getMapper(IUserDao.class);
        User user = userDao.findById(55);
        System.out.println(user);

        session.close();//释放一级缓存

        SqlSession session1=factory.openSession();//再次打开session（不同的了）
        IUserDao userDao1=session1.getMapper(IUserDao.class);
        User user1=userDao1.findById(55);
        System.out.println(user1);

        session1.close();
    }
