Constructor Details

CompositeUriComponentsContributor

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 - a collection of UriComponentsContributor or HandlerMethodArgumentResolvers

CompositeUriComponentsContributor

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 - a collection of UriComponentsContributor or HandlerMethodArgumentResolvers

CompositeUriComponentsContributor

public CompositeUriComponentsContributor(@Nullable
 Collection<?> contributors,
 @Nullable
 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, DefaultFormattingConversionService will be used by default.

Parameters:

contributors - a collection of UriComponentsContributor or HandlerMethodArgumentResolvers

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

Method Details

hasContributors

public boolean hasContributors()

Determine if this CompositeUriComponentsContributor has any contributors.

Returns:

true if this CompositeUriComponentsContributor was created with contributors to delegate to

supportsParameter

public boolean supportsParameter(MethodParameter parameter)

Description copied from interface: UriComponentsContributor

Whether this contributor supports the given method parameter.

Specified by:

supportsParameter in interface UriComponentsContributor

contributeMethodArgument

public void contributeMethodArgument(MethodParameter parameter,
 Object value,
 UriComponentsBuilder builder,
 Map<String,Object> uriVariables,
 ConversionService conversionService)

Description copied from interface: UriComponentsContributor

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.

Specified by:

contributeMethodArgument in interface UriComponentsContributor

Parameters:

parameter - the controller method parameter (never null)

value - the argument value (possibly null)

builder - the builder to update (never null)

uriVariables - a map to add URI variables to (never null)

conversionService - a ConversionService to format values as Strings

contributeMethodArgument

public void contributeMethodArgument(MethodParameter parameter,
 Object value,
 UriComponentsBuilder builder,
 Map<String,Object> uriVariables)

An overloaded method that uses the ConversionService created at construction.
