after it has set all bean properties and satisfiedBeanFactoryAware
,ApplicationContextAware
etc.This method allows the bean instance to perform validation of its overall configuration and final initialization when all bean properties have been set.
- Specified by:
afterPropertiesSet
in interfaceInitializingBean
- Throws:
Exception

Description copied from interface:HandlerAdapter

supports the givenhandler
.- Specified by:

in interfaceHandlerAdapter
- Parameters:

- whether the handler is supported

handle
public reactor.core.publisher.Mono<HandlerResult> handle(ServerWebExchange exchange, Object handler) Description copied from interface:HandlerAdapter
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.- Specified by:
handle
in interfaceHandlerAdapter
- Parameters:
exchange
- current server exchangehandler
- the selected handler which must have been previously checked viaHandlerAdapter.supports(Object)
- Returns:
Mono
that emits a singleHandlerResult
or none if the request has been fully handled and doesn't require further handling.
