How to get all the assets in a Collection in AEM?

Question

I am trying to get all the assets inside a collection in AEM given the path of the collection.

Let's say the path of the collection is /content/dam/collections/public/-/-XZMzZlhkJKIa7-Mg15h/testing

I need to get all the assets inside this collection.

I checked under content/dam/collections the assets are not stored under this location

I even tried by writing a query in query builder in AEM giving type:dam:asset and path:"location of the collection"

I couldn't get any results.

I just need to get all the assets under the collection in Java or QueryBuilder

Resource Collection API will be used to retrieve the assets in a Collection.

Below code should work for you.

Resource resource = resourceResolver
            .getResource("/content/dam/collections/k/kXjI0j44sW4pq2mWc9fE/public collections");
    if (null != resource) {
        log.debug("resource path is {}", resource.getPath());
        ResourceCollection resourceCollection = resource.adaptTo(ResourceCollection.class);
        if (null != resourceCollection) {
            Iterator<Resource> resourceIterator = resourceCollection.getResources();
            while (resourceIterator.hasNext()) {
                Resource damResource = resourceIterator.next();
                log.debug("damResource path is {}", damResource.getPath());
                imagePaths.add(damResource.getPath());
            }
        }
    }
