GRPC Java 1.6.1 已发布,GRPC 是一个高性能、开源、通用的 RPC 框架,面向移动和 HTTP/2 设计,是由谷歌发布的首款基于 Protocol Buffers 的 RPC 框架,GRPC Java 是 GRPC 的 Java 实现。

GRPC 基于 HTTP/2 标准设计,带来诸如双向流、流控、头部压缩、单 TCP 连接上的多复用请求等特性。这些特性使得其在移动设备上表现更好,更省电且节省空间占用。

主要更新内容:

  • Android users should no longer need -keeps in their ProGuard configuration (#2633)

  • gRPC is no longer using the current Thread’s “context ClassLoader” when searching for transport Providers (#2375). Instead it is using the current class’s ClassLoader. This should not break existing users and work out-of-the-box in a larger number of environments

  • Fix support for Google AppEngine Java 8 (#3296)

  • Log netty connection errors at FINE instead of SEVERE (#1768)

  • Update netty to 4.1.14 and tcnative to 2.0.5 (#3307)

  • Channel state API is now implemented via ManagedChannel.getState/notifyWhenStateChanged. This requires LoadBalancer support; custom LoadBalancers should be updated to call updateBalancingState() instead of updatePicker()

  • Referencing CallCredentials is now stable API (#3289). Implementing or consuming CallCredentials is still ExperimentalApi

  • New method ClientCallStreamObserver.cancel() allows clients to cancel RPCs without requiring using an interceptor or Context (#3115)
