handle
reactor.core.publisher.Mono<HandlerResult> handle(ServerWebExchange exchange, Object handler)
Handle the request with the given handler.Implementations are encouraged to handle exceptions resulting from the invocation of a handler in order and if necessary to return an alternate result that represents an error response.
Furthermore since an async
HandlerResult
may produce an error later during result handling implementations are also encouraged toset an exception handler
on theHandlerResult
so that may also be applied later after result handling.- 参数:
exchange
- current server exchangehandler
- the selected handler which must have been previously checked viasupports(Object)
- 返回:
Mono
that emits a singleHandlerResult
or none if the request has been fully handled and doesn't require further handling.
