Method Detail

initModel

public <any> initModel(HandlerMethod handlerMethod,
                       InitBinderBindingContext bindingContext,
                       ServerWebExchange exchange)

Initialize the Model based on a (type-level) @SessionAttributes annotation and @ModelAttribute methods.

Parameters:

handlerMethod - the target controller method

bindingContext - the context containing the model

exchange - the current exchange

Returns:

a Mono for when the model is populated.

invokeModelAttributeMethods

                                          ServerWebExchange exchange)

handleResult

private <any> handleResult(HandlerResult handlerResult,
                           BindingContext bindingContext)

isAsyncVoidType

private boolean isAsyncVoidType(ResolvableType type,
                                @Nullable
                                ReactiveAdapter adapter)

Find @ModelAttribute arguments also listed as @SessionAttributes.

getNameForParameter

public static java.lang.String getNameForParameter(MethodParameter parameter)

Derive the model attribute name for the given method parameter based on a @ModelAttribute parameter annotation (if present) or falling back on parameter type based conventions.

Parameters:

parameter - a descriptor for the method parameter

Returns:

the derived name
