```
default reactor.core.publisher.Mono<Object> resolveArgument(MethodParameter parameter,
                                                            BindingContext bindingContext,
                                                            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.
    指定者:
    resolveArgument 在接口中 HandlerMethodArgumentResolver
    参数:
    parameter - the method parameter
    bindingContext - the binding context to use
    exchange - the current exchange
    返回:
    Mono for the argument value, possibly empty
  - resolveArgumentValue
```
@Nullable
Object resolveArgumentValue(MethodParameter parameter,
                            BindingContext bindingContext,
                            ServerWebExchange exchange)
```
    Resolve the value for the method parameter synchronously.
    参数:
    parameter - the method parameter
    bindingContext - the binding context to use
    exchange - the current exchange
    返回:
    the resolved value, if any
