Dubbo: 分布式通讯框架

Dubbo是一个高性能的分布式RPC框架,主要包括一下部分:

  • Remoting(远程通信): a network communication framework provides sync-over-async and request-response messaging.
  • Clustering(集群): a remote procedure call abstraction with load-balancing/failover/clustering capabilities.
  • Registry(注册中心): a service directory framework for service registration and service event publish/subscription

和Dubbo 2.x的区别

  • Java 8 only, hessian序列化支持Java 8 Optional,暂时不支持容器类,如List, Map
  • 序列化调整到hessian2协议上
  • zookeeper有zkClient调整到curator
  • Spring Boot兼容
  • 注册中心: 删除simple registry
  • 通讯协议: 默认Netty4, 删除thrift,http,Grizzly,rmi等协议支持
  • 容器: 取消Jetty支持,使用Spring Boot替换
  • Docker: 在 Protocol 配置中增加了 exportHost 和 exportPort 参数, 区分容器内绑定的真实地址和注册到注册中心的宿主机地址

Dubbo Spring Boot

不少同学会对Dubbo更多的需求,这当然是对,但是有一些特性可能做在Dubbo和某些框架的集成上更好,如Dubbo Spring Boot,这里列举一下特性:

  • Metrics集成,这个在Dubbo Spring Boot中通过filter机制完成更方便
  • DevOps API: 各种信息暴露
