        for (int i = 1;i<5;i++){
           try {
               this.B(i);
            }catch (Exception e){
                e.printStackTrace();
            }

    }
    @Transactional(propagation = Propagation.REQUIRES_NEW)
    public void B(int i){//可能发生异常的方法B
            User user = new User();
            if (i==2){
                user.setId(2);
                user.setName("No"+i);
                user.setAge(i);
                demoMapper.insertUser(user);//往user表插入一条用户记录
                int a = 1/0;//抛出ArithmeticException异常
            }else {
                user.setId(i);
                user.setName("Yes"+i);
                user.setAge(i);
                demoMapper.insertUser(user);
            }
    }
