Class AbstractWebQueryResolver

java.lang.Object

in.co.akshitbansal.springwebquery.resolver.spring.AbstractWebQueryResolver

All Implemented Interfaces:

org.springframework.web.method.support.HandlerMethodArgumentResolver

Direct Known Subclasses:

AbstractWebQueryPageableArgumentResolver, AbstractWebQuerySpecificationArgumentResolver

public abstract class AbstractWebQueryResolver
extends Object
implements org.springframework.web.method.support.HandlerMethodArgumentResolver

Common base for HandlerMethodArgumentResolver implementations that participate in WebQuery-driven request parsing.

This class centralizes detection of controller method parameters whose declaring method carries WebQuery and exposes a shared helper for retrieving that annotation once support has been established.

Method Details

supportsParameter

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

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

This base implementation uses 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

Parameters:

parameter - method parameter under inspection

Returns:

true when the declaring method has WebQuery, otherwise false

getWebQueryAnnotation

protected WebQuery getWebQueryAnnotation(@NonNull
 @NonNull org.springframework.core.MethodParameter parameter)

Returns the WebQuery annotation declared on the supplied method parameter's controller method.

This helper centralizes annotation lookup for both support detection and downstream configuration resolution. Callers that need boolean support checks should use supportsParameter(MethodParameter); this method is for subclasses that expect a supported parameter and therefore treat missing method metadata as a programming error.

Parameters:

parameter - method parameter whose declaring method is expected to carry WebQuery

Returns:

resolved WebQuery annotation

Throws:

IllegalStateException - if the parameter has no declaring method or the declaring method is not annotated with WebQuery
