org.apache.dubbo.rpc中Result的使用

实现Result的org.apache.dubbo.rpc中的类

限定符和类型	类和说明
class	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.
class	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.

返回Result的org.apache.dubbo.rpc中的方法

限定符和类型	方法和说明
Result	Result.get()
Result	AppResponse.get()
Result	AsyncRpcResult.get() This method will always return after a maximum 'timeout' waiting: 1. if value returns before timeout, return normally. 2. if no value returns after timeout, throw TimeoutException.
Result	Result.get(long timeout, TimeUnit unit)
Result	AppResponse.get(long timeout, TimeUnit unit)
Result	AsyncRpcResult.get(long timeout, TimeUnit unit)
Result	AsyncRpcResult.getAppResponse()
Result	Invoker.invoke(Invocation invocation) invoke.
Result	Filter.invoke(Invoker<?> invoker, Invocation invocation) Make sure call invoker.invoke() in your implementation.
Result	Result.whenCompleteWithContext(BiConsumer<Result,Throwable> fn) Add a callback which can be triggered when the RPC call finishes.
Result	AppResponse.whenCompleteWithContext(BiConsumer<Result,Throwable> fn)
Result	AsyncRpcResult.whenCompleteWithContext(BiConsumer<Result,Throwable> fn)
