方法详细资料

preHandleRequest

BizContext preHandleRequest(RemotingContext remotingCtx,
                            T request)

Pre handle request, to avoid expose RemotingContext directly to biz handle request logic.

参数:

remotingCtx - remoting context

request - request

返回:

BizContext

handleRequest

void handleRequest(BizContext bizCtx,
                   AsyncContext asyncCtx,
                   T request)

Handle request with AsyncContext.

参数:

bizCtx - biz context

asyncCtx - async context

request - request

handleRequest

Object handleRequest(BizContext bizCtx,
                     T request)
              throws Exception

Handle request in sync way.

参数:

bizCtx - biz context

request - request

抛出:

Exception

interest

String interest()

The class name of user request. Use String type to avoid classloader problem.

返回:

interested request's class name

getExecutor

Executor getExecutor()

Get user executor.

返回:

executor

processInIOThread

boolean processInIOThread()

Whether deserialize and process biz logic in io thread. Notice: If return true, this will have a strong impact on performance.

返回:

true for processing in io thread

timeoutDiscard

boolean timeoutDiscard()

Whether handle request timeout automatically, we call this fail fast processing when detect timeout. Notice: If you do not want to enable this feature, you need to override this method to return false, and then call BizContext.isRequestTimeout() to check by yourself if you want.

返回:

true if you want to enable fail fast processing, otherwise return false

setExecutorSelector

void setExecutorSelector(UserProcessor.ExecutorSelector executorSelector)

Use this method to set executor selector.

参数:

executorSelector - executor selector

getExecutorSelector

UserProcessor.ExecutorSelector getExecutorSelector()

Use this method to get the executor selector.

返回:

executor selector
