--------------------------------------------------------------------------------
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
