How to query with greaterThan for an embedded document using Spring Data MongoDB Repository?

Member.class

@Document(collection = "alfagift_member")
public class Member {

    @Field(value = "full_name")
    private String fullName;

    @Field(value = "member_id")
    private String memberId;

    @Field(value = "pin")
    private Pin pin;
}

Pin.class

public class Pin {

	@Field(value = "encrypted_value")
	private String encryptedValue;
	
	@Field(value = "last_blocked")
	private Date lastBlocked;
}

MemberRepository.class

@Repository
public interface MemberRepository extends MongoRepository<Member, String> {

  @Query(value="{'member_id' : ?0}, {'pin.last_blocked' : ?1}")
  Member findByMemberIdAndLastBlockedGreaterThan(Integer memberId, Date now);
}

> Then I tried to make a query method like this, but the function of greaterthan itself doesn't work

I was confused, how to solve it ??

Data in MongoDB

{
  "_id": ObjectId("5f1fa9876b911d2b27d0bcf5"),
  "full_name": "this is my name",
  "pin": {
    "encrypted_value": "e9b0d0aae93291679b304f9d3c058029fa4253ccaf366cae3aeb473099b7aff8:qcfq9josgstqjcoun0isnvmja3",
    "last_blocked": ISODate("2020-08-03T05:00:31.597Z")
  },
  "member_id": 2200146,
  "_class": "id.alfadigital.alfagift.service.account.v1.db.mongo.domain.Member"
}

And parameter sending

Date now = new Date(System.currentTimeMillis() - TimeUnit.HOURS.toMillis(1));
Member member = memberRepository.findByMemberIdAndLastBlockedGreaterThan(memberId, now);	

• Update the repository like this

    @Repository
    public interface MemberRepository 
                             extends MongoRepository<Member, String> {

   
        Member findByMemberIdAndPinLastBlockedGreaterThan(Integer memId, 
                                                          Date now);
    }

• You are deducting one hour from current time and your stored document has blocked time before that. For testing purpose, reduct 5 hours and query.

   Date now = new Date(System.currentTimeMillis() - TimeUnit.HOURS.toMillis(5));
