ApplicationContext ac=new ClassPathXmlApplicationContext("com/ch/test/bean.xml");

@Resource
    private SessionFactory sessionFactory;
    
    @Test
    public void testTA(){
        
        Session session=sessionFactory.openSession();
        
        Main main=new Main();
        main.setMain_content("什么课考试时间打开手机电视宽带建设");
        
        Second second=new Second();
        second.setSec_content("sasasasasa");
        second.setMain(main);
        
        session.save(main);
        session.save(second);
    }

2.未将Dao加入bean导致的异常
