        }
    
    }
    
    --------------------------------------------------------------------------------
    保证lcn-manager项目正常启动
    
    
    集成SringCloud:
    
    在不同的微服务中启动类上加:
    @EnableDistributedTransaction //开启分布式事务管理
    
    /**
     * 新增数据
     *
     * @param user 实例对象
     * @return 实例对象
     */
    @Override
    //调用方与被调用方的业务方法上加注解即可
    @LcnTransaction
    @Transactional
    public User insert(User user) {
        this.userDao.insert(user);
        return user;
    }
    

     最坑的是版本的兼容性,这个东西只能试验试错,总结
