Document

Synthesize an annotation from the supplied annotation by wrapping it in a dynamic proxy that transparently enforces attribute alias semantics for annotation attributes that are annotated with AliasFor @AliasFor .

Usage

From source file:com.github.ljtfreitas.restify.http.spring.contract.metadata.reflection.SpringWebJavaMethodParameterMetadata.java

public SpringWebJavaMethodParameterMetadata(java.lang.reflect.Parameter javaMethodParameter,
        Class<?> targetClassType) {
    this.type = JavaType.of(new JavaTypeResolver(targetClassType).parameterizedTypeOf(javaMethodParameter));

    this.pathParameter = AnnotationUtils
            .synthesizeAnnotation(javaMethodParameter.getAnnotation(PathVariable.class), javaMethodParameter);

    this.headerParameter = AnnotationUtils
            .synthesizeAnnotation(javaMethodParameter.getAnnotation(RequestHeader.class), javaMethodParameter);

    this.bodyParameter = AnnotationUtils
            .synthesizeAnnotation(javaMethodParameter.getAnnotation(RequestBody.class), javaMethodParameter);

    this.queryParameter = AnnotationUtils
            .synthesizeAnnotation(javaMethodParameter.getAnnotation(RequestParam.class), javaMethodParameter);

    this.name = Optional.ofNullable(pathParameter).map(PathVariable::value).filter(s -> !s.trim().isEmpty())
            .orElseGet(() -> Optional.ofNullable(headerParameter).map(RequestHeader::value)
                    .filter(s -> !s.trim().isEmpty())
                    .orElseGet(() -> Optional.ofNullable(queryParameter).map(RequestParam::value)
                            .filter(s -> !s.trim().isEmpty())
                            .orElseGet(() -> Optional.ofNullable(javaMethodParameter.getName()).orElseThrow(
                                    () -> new IllegalStateException("Could not get the name of the parameter "
                                            + javaMethodParameter)))));

    this.serializerType = SpringWebEndpointMethodParameterSerializer.of(this);
