 依赖 要实现您自己的 Dubbo 扩展,通常只需依赖 API jar 就可以满足您的需求。例如:
 <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
 您的项目进行代码审查。随后,您可以对这些代码进行改进。  ">

 <meta itemprop=name content="使用 Apache Skywalking 做分布式跟踪">
 <meta itemprop=description content="Apache Skywalking 简介 Apache Skywalking 专门为微服务架构和云原生架构系统而设计并且支持分布式链路追踪的APM系统。Apache Skywalking 通过加载探针的方式收集应用调用链路信息,并对采集的调用链路信息进行分析,生成应用间关系和服务间关系以及服务指标。Apache Skywalking 目前支持多种语言,其中包括 Java,.Net Core,Node.js 和 Go 语言。
 目前 Skywalking 已经支持从 6 个可视化维度剖析分布式系统的运行情况。总览视图是应用和组件的全局视图,其中包括组件和应用数量,应用的告警波动,慢服务列表以及应用吞吐量;拓扑图从应用依赖关系出发,展现整个应用的拓扑关系;应用视图则是从单个应用的角度,展现应用的上下游关系,TopN 的服务和服务器,JVM 的相关信息以及对应的主机信息。服务视图关注单个服务入口的运行情况以及此服务的上下游依赖关系,依赖度,帮助用户针对单个服务的优化和监控;调用链展现了调用的单次请求经过的所有埋点以及每个埋点的执行时长;告警视图根据配置阈值针对应用、服务器、服务进行实时告警。
 Dubbo 与 Apache Skywalking 编写 Dubbo 示例程序 Dubbo 实例程序已上传到 Github 仓库中。方便大家下载使用。
