Constructor Detail

CompositeUriComponentsContributorback to summary
public CompositeUriComponentsContributor(UriComponentsContributor... contributors)

Create an instance from a collection of UriComponentsContributors or HandlerMethodArgumentResolvers. Since both of these tend to be implemented by the same class, the most convenient option is to obtain the configured HandlerMethodArgumentResolvers in RequestMappingHandlerAdapter and provide that to this constructor.

Parameters
contributors:UriComponentsContributor[]

a collection of UriComponentsContributor or HandlerMethodArgumentResolvers

CompositeUriComponentsContributorback to summary
public CompositeUriComponentsContributor(Collection<?> contributors)

Create an instance from a collection of UriComponentsContributors or HandlerMethodArgumentResolvers. Since both of these tend to be implemented by the same class, the most convenient option is to obtain the configured HandlerMethodArgumentResolvers in RequestMappingHandlerAdapter and provide that to this constructor.

Parameters
contributors:Collection<?>

a collection of UriComponentsContributor or HandlerMethodArgumentResolvers

CompositeUriComponentsContributorback to summary
public CompositeUriComponentsContributor(Collection<?> contributors, ConversionService cs)

Create an instance from a collection of UriComponentsContributors or HandlerMethodArgumentResolvers. Since both of these tend to be implemented by the same class, the most convenient option is to obtain the configured HandlerMethodArgumentResolvers in the RequestMappingHandlerAdapter and provide that to this constructor.

If the ConversionService argument is null, org.springframework.format.support.DefaultFormattingConversionService will be used by default.

Parameters
contributors:Collection<?>

a collection of UriComponentsContributor or HandlerMethodArgumentResolvers

cs:ConversionService

a ConversionService to use when method argument values need to be formatted as Strings before being added to the URI

Doc from org.springframework.web.method.support.UriComponentsContributor.contributeMethodArgument.

Process the given method argument and either update the UriComponentsBuilder or add to the map with URI variables to use to expand the URI after all arguments are processed.

Parameters
parameter:MethodParameter

the controller method parameter (never null)

value:Object

builder:UriComponentsBuilder

the builder to update (never null)

uriVariables:Map<String, Object>

a map to add URI variables to (never null)
