    • 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(MethodParameter, BindingContext, 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
