 尽管在 Spring 应用中,可以通过 @Value 或者 Environment 的方式获取外部配置,其代码简洁性以及类型转换灵活性存在明显的不足。因此,Spring Boot 提出了外部化配置(External Configuration)的感念,即通过程序以外的配置源,动态地绑定指定类型。

 Dubbo 生态系统 我们建议您将扩展加入到 Dubbo 生态系统。使用这种模式,可以使 Dubbo 的核心仓库更干净,并且可以减少维护工作。更少的代码也可以提高核心仓库的构建速度。

 <dependency> <groupId>org.apache.dubbo</groupId> <artifactId>dubbo-serialization-api</artifactId> <version>${dubbo.version}</version> </dependency> Src指导 通常,要实现特殊的扩展,只需要参考开发者指南,实现Dubbo必要的接口和合适的扩展即可。除此之外,还有一些其它的事项需要注意:
- 良好的测试,您需要编写单元测试和冒烟测试以消除潜在的 bug。 没有警告,如有不可避免的警告,请使用 @SuppressWarnings 阻止它,但是请不要乱用。 README。添加必要的自述以说明如何使用扩展,以及需要注意的事项。 许可证:请确保使用Apache License 2.0。  通知社区  提交您的代码到 github。 加入邮件列表(建议)。点击这里查看如何加入邮件列表。 发送一封邮件到 dev@incubator.dubbo.apache.org 通知社区。 通常,发送邮件之后,社区会对您的扩展进行讨论,dubbo 组的管理员会联系您转移您的项目到 dubbo 生态系统。  转移项目到dubbo生态系统  dubbo 组的管理员会请您将您的项目的所有者转让给 dubbo。 dubbo 组的管理员会在 dubbo 组下新建一个项目并邀请您加入到这个项目。 一旦您接受邀请,您可以将您的项目转移到 dubbo 组下的新项目里。 dubbo 组的成员会对

 数据反序列化是最容易被被攻击者利用的一个环节,攻击者利用它执行 RCE 攻击等窃取或破坏服务端数据,用户在切换序列化协议或实现前,
