Fetching mongo DB object using Spring Data MongoDB

Question

I am trying to query mongodb object and based on the Id ie 456 present in responseBody.

Below is the Java code I have written

String Id = "456";

Query query = new Query();
query.addCriteria(Criteria.where("responseBody.Id").is(Id));
dataList = mongoTemplate.find(query, Data.class);

the above code is working perfectly fine. But because of the change in requirements I need to store the JSON in the responseBody as shown below.

My query is how do I fetch the entire mongoDB object by querying the Id that I have and the object being present in responseBody -> body.

You can simply use JPARespository classes and use the methods like findById or findByName as follows:

@Transactional
@Repository
public interface InstituteRepository extends MongoRepository<Institute, String> {

    Institute findByInstituteId(long id);

}
