-------------------------------------
Summary: Sling Models injector for CAConfig
Key: SLING-7256
URL: https://issues.apache.org/jira/browse/SLING-7256
Project: Sling
Issue Type: New Feature
Affects Versions: Sling Models Impl 1.4.4
Reporter: Henry Kuijpers
It would be great to have a Sling Models injector for CAConfig.
An example could be:
{code}
@Component
public class ContextAwareConfigurationInjector implements Injector {
public String getName() {
return "ca-config";
}
public Object getValue(Object adaptable, String name, Type declaredType,
AnnotatedElement element,
DisposalCallbackRegistry callbackRegistry) {
if (isConfigurationObject(declaredType)) {
final Resource resource;
if (adaptable instanceof Resource) {
// TODO: Is this always the correct resource? (Most often we
want the one in /content)
// So we do not want /conf/... for example
resource = (Resource) adaptable;
} else if (adaptable instanceof SlingHttpServletRequest) {
final SlingHttpServletRequest request =
(SlingHttpServletRequest)adaptable;
final ResourceResolver resourceResolver =
request.getResourceResolver();
resource = resourceResolver.resolve(request,
request.getRequestURI());
} else {
throw new IllegalArgumentException("Either a resource or the
request should be used");
}
final ConfigurationBuilder builder =
resource.adaptTo(ConfigurationBuilder.class);
if (builder != null) {
return builder.as((Class<?>) declaredType);
}
}
return null;
}
private static boolean isConfigurationObject(Type type) {
if (!(type instanceof Class<?>)) {
return false;
}
Class<?> clazz = (Class<?>) type;
return clazz.isAnnotation() &&
clazz.isAnnotationPresent(Configuration.class);
}
}
{code}
+ annotation:
{code}
@Target({ ElementType.FIELD, ElementType.METHOD, ElementType.PARAMETER })
@Retention(RetentionPolicy.RUNTIME)
@InjectAnnotation
@Source("ca-config")
@Qualifier
public @interface CaConfig {
}
{code}
