接口	说明
AsyncContext	AsyncContext works like javax.servlet.AsyncContext in the Servlet 3.0.
Constants

Filter.Listener
Invocation	Invocation.
Invoker<T>	Invoker.
InvokerListener	InvokerListener.

类概要

类	说明
AppResponse	AsyncRpcResult is introduced in 3.0.0 to replace RpcResult, and RpcResult is replaced with AppResponse: AsyncRpcResult is the object that is actually passed in the call chain AppResponse only simply represents the business result The relationship between them can be described as follow, an abstraction of the definition of AsyncRpcResult: Public class AsyncRpcResult implements CompletionStage { ...... } AsyncRpcResult is a future representing an unfinished RPC call, while AppResponse is the actual return type of this call.
AsyncContextImpl
AsyncRpcResult	This class represents an unfinished RPC call, it will hold some context information for this call, for example RpcContext and Invocation, so that when the call finishes and the result returns, it can guarantee all the contexts being recovered as the same as when the call was made before any callback is invoked.
AttachmentsAdapter	已过时
AttachmentsAdapter.ObjectToStringMap	已过时
FutureContext	Used for async call scenario.
ListenableFilter	It's recommended to implement Filter.Listener directly for callback registration, check the default implementation, see ExceptionFilter, for example.
RpcConstants	已过时 Replace to org.apache.dubbo.common.Constants
RpcContext	Thread local context.
RpcInvocation	RPC Invocation.
RpcStatus	URL statistics.
TimeoutCountDown
