in.co.akshitbansal.springwebquery.resolver.spring.AbstractWebQueryPageableArgumentResolver

All Implemented Interfaces:

org.springframework.web.method.support.HandlerMethodArgumentResolver

Direct Known Subclasses:

WebQueryDTOAwarePageableArgumentResolver, WebQueryEntityAwarePageableArgumentResolver

public abstract class AbstractWebQueryPageableArgumentResolver
extends AbstractWebQueryResolver

Base resolver for Pageable parameters participating in WebQuery-aware sorting.

This class delegates standard page/size parsing to Spring's PageableHandlerMethodArgumentResolver and lets subclasses validate and remap sort properties against either entity or DTO metadata.

Constructor Details

AbstractWebQueryPageableArgumentResolver

protected AbstractWebQueryPageableArgumentResolver(org.springframework.data.web.PageableHandlerMethodArgumentResolver delegate)

Creates a pageable resolver base with shared global defaults.

Parameters:

delegate - Spring's pageable resolver used for base pagination parsing

Method Details

supportsParameter

public boolean supportsParameter(@NonNull
 @NonNull org.springframework.core.MethodParameter parameter)

Description copied from class: AbstractWebQueryResolver

Determines whether the supplied method parameter belongs to a controller method annotated with WebQuery.

This base implementation uses AbstractWebQueryResolver.getWebQueryAnnotation(MethodParameter) as the single source of truth for annotation lookup. Missing methods or missing annotations are treated as "not supported" rather than exceptional conditions so Spring MVC can continue evaluating other resolvers.

Specified by:

supportsParameter in interface org.springframework.web.method.support.HandlerMethodArgumentResolver

Overrides:

supportsParameter in class AbstractWebQueryResolver

Parameters:

parameter - method parameter under inspection

Returns:

true when the declaring method has WebQuery, otherwise false

resolveArgument

public org.springframework.data.domain.Pageable resolveArgument(@NonNull
 @NonNull org.springframework.core.MethodParameter parameter,
 org.springframework.web.method.support.ModelAndViewContainer mavContainer,
 @NonNull
 @NonNull org.springframework.web.context.request.NativeWebRequest webRequest,
 org.springframework.web.bind.support.WebDataBinderFactory binderFactory)

resolvePageable

protected abstract org.springframework.data.domain.Pageable resolvePageable(org.springframework.data.domain.Pageable pageable,
 AbstractWebQueryPageableArgumentResolver.QueryConfiguration queryConfig)

Validates and remaps pageable sorting according to the effective query configuration.

Parameters:

pageable - pageable parsed from the request

queryConfig - effective query configuration derived from WebQuery

Returns:

pageable with validated and possibly remapped sort orders

getQueryConfiguration

protected AbstractWebQueryPageableArgumentResolver.QueryConfiguration getQueryConfiguration(@NonNull
 @NonNull org.springframework.core.MethodParameter parameter)

Extracts pageable-specific query metadata directly from the WebQuery annotation declared on the supplied controller method.

Unlike specification resolution, pageable handling does not consume operator policies or AST settings, so this configuration contains only the entity type, optional DTO type, and the declared field mappings retained for entity-aware sort validation and remapping.

Parameters:

parameter - supported method parameter whose declaring method carries WebQuery

Returns:

effective configuration used by pageable resolvers for sort validation
