I am trying to query a mongo db document That's contain nested array.
Here is my beans :
public class Invitation {
#JsonIgnore
private UUID id;
#DBRef
private Personne personne;
private List<Boolean> disponibilites;
private InvitationStatus status;
#DBRef
private Groupe groupe;
And Groupe :
#Document(collection = "groupe")
public class Groupe {
#Id
private String id;
private String nom;
private List<Personne> membres;
#DBRef
private Personne owner;
public Groupe(){
}
And here is the document im trying to query :
#Document(collection = "evenement")
public class Sondage {
#Id
private String id;
private String nom;
// #JsonFormat(pattern="yyyy-MM-dd HH:mm:ss")
private Date dateCreation;
private Date dateExpiration;
private List<Invitation> invitations;
So here is my query :
Criteria finished = Criteria.where(SONDAGE_STATUS).is(SondageStatus.FINISHED);
Criteria isExpired = Criteria.where(DATE_EXPIRATION).gt(new Date());
// liste des personnes invitées dans un groupe
Criteria member = Criteria.where("invitations.groupe.membres").elemMatch(Criteria.where("id").is(personId));
Query bquery = new Query(new Criteria().andOperator(isExpired,finished,member));
bquery.with(sort);
bquery.fields().position("invitations.groupe.membres", 1);
List<Sondage> membersInvitationList = mongoTemplate.find(bquery, Sondage.class);
When I launch my service I get this error : org.springframework.data.mapping.model.MappingException: Invalid path reference invitations.groupe.membres.id! Associations can only be pointed to directly or via their id property!
Can anyone help me please ?

I have the below object
#Document(collection = "qr_code")
public class QrCode implements Serializable {
private static final long serialVersionUID = 1L;
#Id
private String qrCodeId;
#Field
private String codePay;
private LocalDateTime expiredIn;
}
I have this query to check if a codePay exists or not
boolean existsByCodePay(String codePay);
I want another query to check if a QrCode is expired or not, based on attribute expiredIn, that's to say the QrCode expired when expiredIn < LocalDateTime.now()
#Query(???)
boolean isQrCodeExpired(String codePay);
The raw mongodb query can be something like this :
{
"expiredIn":{
$gt : new Date()
}
}
In Spring data findAll method reference object is coming as null
I am using Reactive Mongo Repository
Ex Parent Object
#Data
#Document(collection = "country")
public class CountryBean {
#Id
private String id;
private String name;
}
Child Object
#Document(collection = "city")
public class CityBean {
#Id
private String id;
#Field(name = "name")
private String name;
#Field(name = "city_code")
private String cityCode;
#Field(name = "show_city")
private boolean showCity;
#DocumentReference(lazy = false)
private StateBean state;
}
Country Collection
State Collection (Here we can see the country Attribute)
But When trying to fetch from DB, I am getting country attribute as null. Tried both lazy true/false, but not getting country object along with state object.
#GetMapping("/get-all-state")
Flux<StateBean> allState() {
Flux<CountryBean> ct = countryRepository.findAll();
Flux<StateBean> bean= stateRepository.findByCountry(ct.blockFirst());
return bean;
}
[{"id":"6237a912850ceb6261998a53","name":"Bangalore","statecode":"39","country":null},{"id":"6237a94a850ceb6261998a55","name":"delhi","statecode":"39","country":null}]
I have below two Document structures. In the structure CRMContact.orgGroupId == OrganizationGroup.id. I would like to fetch all the CRMContact document that matches with sharedGroupIds and also select only a few fields from CRMContact and only OrganizationGroup.groupownername from OrganizationGroup and match/populate groupId (with only one field [groupownername] populated). I have used below custom implementation but didn't work.
I have included aggregarionsNotWorking which is not working and aggregarions returning entire OrganizationGroup populated. How to achieve this i.e. just to populate groupownername field, using spring data mongodb?
#Document(collection = "ww_crm_contact")
public class CRMContact{
#Id
protected String id;
private String displayName;
private String firstName;
private String middleName;
private String lastName;
private OrganizationGroup groupId; //Ignore //Modified field name orgGroupId
#Indexed(name = "CRMCONTACT_SHAREDGROUPID_IDX",background = true)
private List<String> sharedGroupIds = new LinkedList<>();
#Indexed(name = "CRMCONTACT_ORGGROUPID_IDX",background = true)
private String orgGroupId;
}
#Document(collection = "ww_organization_groups")
public class OrganizationGroup {
private static final long serialVersionUID = 600049975643062552L;
#Id
protected String id;
private String groupName;
private int riaId;
private Boolean isPrivate;
private String description;
private Boolean deleted;
#Transient
private int count;
private String groupownerid;
private String groupownername;
}
#Repository
public class CustomCRMContactDAO {
#Autowired
MongoTemplate mongoTemplate;
public List<CRMContact> getContactsPresentInGroup(List<ObjectId> objectIds){
LookupOperation lookupOperation = LookupOperation.newLookup().from("ww_organization_groups").localField("orgGroupId").foreignField("_id").as("groupId");
ProjectionOperation fields = project("firstName","lastName", "primaryId","displayName","groupId.groupownername");
Aggregation aggregarionsNotWorking = Aggregation.newAggregation(Aggregation.match(Criteria.where("sharedGroupIds").in(objectIds)),lookupOperation,unwind("groupId"),fields); //Not Working even if I change the field only to groupownername
Aggregation aggregarions = Aggregation.newAggregation(Aggregation.match(Criteria.where("sharedGroupIds").in(objectIds)),lookupOperation,fields); //
List<CRMContact> crmContacts = mongoTemplate.aggregate(aggregarions, "ww_crm_contact",CRMContact.class).getMappedResults();
return crmContacts;
}
}
I have the following Spring Data MongoDB document:
#Document(collection = "messages")
#CompoundIndexes({ #CompoundIndex(name = "chatId_messageId", def = "{'chatId': 1, 'messageId': 1}") })
public class Message implements Serializable {
private static final long serialVersionUID = -1590112217771926691L;
#Id
private String id;
private Long chatId;
private Integer messageId;
private Post post;
}
the Post model(which is not Spring Data MongoDB document) looks like:
public class Post implements Serializable {
private static final long serialVersionUID = -886664249197573502L;
private String id;
}
I'd like to add index to the Message.post.id field.
How it can be done with Spring Data MongoDB and Message.post field declaration in Message document ?
If you want to add Message.post.id to an already compound index, then do it like
#Document(collection = "messages")
#CompoundIndexes({ #CompoundIndex(name = "chatId_messageId", def = "{'chatId': 1, 'messageId': 1, 'Message.post.id' : 1}") })
public class Message implements Serializable {
private static final long serialVersionUID = -1590112217771926691L;
#Id
private String id;
private Long chatId;
private Integer messageId;
private Post post;
}
Compound indexes are indexes that have more than one indexed field, so ideally, the most restrictive field should be to the left of the B-tree. If you want to index by sex and birth, for instance, the index should begin by birth, as it is much more restrictive than sex.
Or if you want to treat it as a saperate index, then create index using #Indexed like
public class Post implements Serializable {
private static final long serialVersionUID = -886664249197573502L;
#Indexed
private String id;
}
Updated
For more info regarding how queries with sub fields of compound index works, check Documentation
I have the above domain structure where I have list of Companies in the product and the aim is not make entry in mongoDB when I have exact match for companies & productId already present in the DB.
#Entity
public class Mobile {
#Id
private Integer id;
private String imei;
private Product productInfo;
// ...
}
#Entity
public class Product {
#Id
private Integer id;
private String productId;
private List<Company<?>> companies;
// ...
}
#JsonTypeInfo(use = JsonTypeInfo.Id.NAME,
include = JsonTypeInfo.As.PROPERTY, property = "type")
#JsonSubTypes({
#JsonSubTypes.Type(name= "samsung", value = Samsung.class),

public class Company<T> implements Serializable {
private static final long serialVersionUID = -8869676577723436716L;
private T companyInfo;
private String type;
// ...
}
I am using mongo template and I have tried to use find as shown below but id didn't work
template.find(Query.query(Criteria.where("product.companies").is(companList),Mobile.class);
