      Resolve the argument value.
      指定者:
      resolve 在接口中 HttpServiceArgumentResolver
      参数:
      argument - the argument value
      parameter - the method parameter for the argument
      requestValues - builder to add HTTP request values to
      返回:
      true if the argument was resolved, false otherwise

    • addRequestValue

      protected abstract void addRequestValue(String name, Object value, cn.taketoday.core.MethodParameter parameter, HttpRequestValues.Builder requestValues)
      Add the given, single request value. This may be called multiples times if the request value is multivalued.

      If the resolver was created with a ConversionService, the value will have been converted to a String and may be cast down.

      参数:
      name - the request value name
      value - the value
      parameter - the method parameter type, nested if Map, List/array, or Optional
      requestValues - builder to add the request value to
