Method Detail

resolveArgument

default reactor.core.publisher.Mono<Object> resolveArgument(org.springframework.core.MethodParameter parameter,
                                                            BindingContext bindingContext,
                                                            org.springframework.web.server.ServerWebExchange exchange)

Resolve the value for the method parameter.

By default this simply delegates to resolveArgumentValue(org.springframework.core.MethodParameter, org.springframework.web.reactive.BindingContext, org.springframework.web.server.ServerWebExchange) for synchronous resolution.

Specified by:

resolveArgument in interface HandlerMethodArgumentResolver

Parameters:

parameter - the method parameter

bindingContext - the binding context to use

exchange - the current exchange

Returns:

Mono for the argument value, possibly empty

resolveArgumentValue

@Nullable
Object resolveArgumentValue(org.springframework.core.MethodParameter parameter,
                                      BindingContext bindingContext,
                                      org.springframework.web.server.ServerWebExchange exchange)

Resolve the value for the method parameter synchronously.

Parameters:

parameter - the method parameter

bindingContext - the binding context to use

exchange - the current exchange

Returns:

the resolved value, if any
