    }
  ],
  "_class": "com.traveldiaries.categories.Categories"
}

How should I Query to update it?

Answer 1

Do you have a specific problem or are you asking in general?

If you've already saved your data, you probably already have a repository. You need to add a method to the interface that will define on the basis of which parameters you want to search for the object, for example:

@Repository
public interface SomeDocumentRepository extends MongoRepository<SomeDocument, String> {
   List<SomeDocument> findByName(String name);
}

Now you can query for an object, modify it, and then save it again. Similarly, you will add a new object.

SomeDocumentRepository repository;

void someMethod(){
    SomeDocument mongoDocument = repository.findByName("Causual");
    CategoryPackage categoryPackage = new CategoryPackages();
    // some operations on the object
    mongoDocument.getCategoryPackages.add(categoryPackage);
    
    repository.save(mongoDocument);
}

In short, that's it. If you have a specific problem, describe it in more detail and add a code snippet.
