Spring REST fetching related entities

Question

I'm Django developer and I wanna try Java and Spring. Can somebody guide me, I have entity SomeModel and it's related as many to one RelatedModel. So my problem is returning the content of SomeModel with list of his RelatedModel in API endpoint like:

"title": "Generations",
"description": "Short article about generations",
"related_items": [
    {
        "id": 5,
        "label": "text"
    }

]

Cause Django contains serializers to those deals, that accept entities' data and parse that to JSON according to serializer's class field, also supporting nested serializers as relations.

I would be grateful if you suggest some repositories with big Spring applications as an example, great books, or articles on that theme, cause it is hard for me to rebuild my mind and I tired from huge amount of ultra-simple article's examples.

You probably haven't linked the entities correctly.
