Method Detail

getAnnotationType

public Class<QueryValue> getAnnotationType()

Specified by:

getAnnotationType in interface AnnotatedArgumentBinder<QueryValue,T,HttpRequest<?>>

Returns:

The annotation type.

bind

public ArgumentBinder.BindingResult<T> bind(ArgumentConversionContext<T> context,
                                            HttpRequest<?> source)

Binds the argument with QueryValue annotation to the request (Also binds without annotation if request body is not permitted). It will first try to convert to ConvertibleMultiValues type and if conversion is successful, add the corresponding parameters to the request. (By default the conversion will be successful if the Format annotation is present and has one of the supported values - see MultiValuesConverterFactory for specific converters). Otherwise the uri template will be used to deduce what will be done with the request. For example, simple parameters are converted to String

Specified by:

bind in interface ArgumentBinder<T,HttpRequest<?>>

Parameters:

context - The ArgumentConversionContext

source - The source

Returns:

An Optional of the value. If no binding was possible Optional.empty()
