All Implemented Interfaces:

org.springframework.web.method.support.HandlerMethodArgumentResolver

public class WebQueryEntityAwareSpecificationArgumentResolver
extends WebQuerySpecificationArgumentResolver

Entity-based resolver for Specification parameters handled via method-level WebQuery.

This resolver is active when WebQuery.dtoClass() is not configured (i.e. equals void.class). It validates incoming RSQL selectors against entity fields and optional FieldMapping aliases before producing a JPA specification.

Constructor Details

WebQueryEntityAwareSpecificationArgumentResolver

public WebQueryEntityAwareSpecificationArgumentResolver(Set<RSQLDefaultOperator> defaultOperators,
 Set<? extends RSQLCustomOperator<?>> customOperators,
 AnnotationUtil annotationUtil,
 boolean globalAllowAndOperator,
 boolean globalAllowOrOperator,
 int globalMaxASTDepth)

Creates an entity-aware RSQL specification resolver.

Parameters:

defaultOperators - built-in operators accepted in RSQL expressions

customOperators - custom operators supported by parser and predicates

annotationUtil - utility for resolving annotations and configuration checks

globalAllowAndOperator - whether AND nodes are allowed by default when @WebQuery does not override that behavior

globalAllowOrOperator - whether OR nodes are allowed by default when @WebQuery does not override that behavior

globalMaxASTDepth - maximum AST depth allowed by default when @WebQuery does not override that behavior

Method Details

supportsParameter

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

Determines whether this resolver should handle the given parameter.

Parameters:

parameter - method parameter under inspection

Returns:

true when parameter is a Specification with method-level WebQuery and no DTO class is configured

resolveArgument

public @Nullable Object resolveArgument(@NonNull
 @NonNull org.springframework.core.MethodParameter parameter,
 @Nullable org.springframework.web.method.support.ModelAndViewContainer mavContainer,
 @NonNull
 @NonNull org.springframework.web.context.request.NativeWebRequest webRequest,
 @Nullable org.springframework.web.bind.support.WebDataBinderFactory binderFactory)
                                 throws Exception

Resolves a Specification from the configured RSQL request parameter.

Parameters:

parameter - controller method parameter being resolved

mavContainer - current MVC container

webRequest - current request

binderFactory - binder factory

Returns:

resolved specification, or Specification.unrestricted() when no filter exists

Throws:

Exception - when resolution fails
