public class ModelAttributeMethodArgumentResolver extends HandlerMethodArgumentResolverSupport
Resolve@ModelAttributeannotated method arguments.Model attributes are sourced from the model, or created using a default constructor and then added to the model. Once created the attribute is populated via data binding to the request (form data, query params). Validation also may be applied if the argument is annotated with
@javax.validation.Validor Spring's own@org.springframework.validation.annotation.Validated.When this handler is created with
useDefaultResolution=trueany non-simple type argument and return value is regarded as a model attribute with or without the presence of an@ModelAttribute.- 从以下版本开始:

ModelAttributeMethodArgumentResolver
public ModelAttributeMethodArgumentResolver(ReactiveAdapterRegistry adapterRegistry, boolean useDefaultResolution)
Class constructor with a default resolution mode flag.- 参数:
adapterRegistry- for adapting to other reactive types from and to MonouseDefaultResolution- if "true", non-simple method arguments and return values are considered model attributes with or without a@ModelAttributeannotation present.
