I am getting this undefined field 'active' error, but active field exist in schema. This was working previously without any errors, suddenly this error appears:
My Solr Document:
#Data

public class SDocument {
#Id
#Field
private String indexId;
#Field("code")
private String code;
#Field("name")
private String name;
#Field("active")
private Boolean active;
}
I'm using spring boot with solrCrudRepository and query was
#Query(value = "code:?0* name:?0*", filters = "active:?1")
List<SDocument> findAllergenList(String searchKey, Boolean isActive);

I'd like to find all Offer documents by Offer.ProductProperties.brand:
#Document(collection = "offers")
public class Offer {
#Id
private String id;
#NotNull
#DBRef
private ProductProperties properties;
ProductProperties:
#Document(collection = "product_properties")
public class ProductProperties {
#Id
private String id;
#NotNull
#NotEmpty
private String brand;
Service:
Flux<ProductProperties> all = productPropertiesRepository.findAllByBrand(brand);
List<String> productPropIds = all.toStream()
.map(ProductProperties::getId)
.collect(Collectors.toList());
Flux<Offer> byProperties = offerRepository.findAllByProperties_Id(productPropIds);
But unfortunately byProperties is empty. Why?
My repository:
public interface OfferRepository extends ReactiveMongoRepository<Offer, String> {
Flux<Offer> findAllByProperties_Id(List<String> productPropertiesIds);
}
How to find all Offers by ProductProperties.brand?
Thanks!
After reading some documentation found out that You cannot query with #DBRef. Hence the message
Invalid path reference properties.brand! Associations can only be
pointed to directly or via their id property
If you remove DBRef from the field, you should be able to query by findAllByProperties_BrandAndProperties_Capacity.
So the only ways is how you are doing. i.e. Fetch id's and query by id.
As I said in the comment, the reason it is not working is because return type of findAllByProperties_Id is a Flux. So unless u execute a terminal operation, you wont have any result. Try
byProperties.collectList().block()
I am not so into Spring Data JPA and I have the following doubt about how to implement a simple query.
I have this AccomodationMedia entity class mapping the accomodation_media on my database:
#Entity
#Table(name = "accomodation_media")
public class AccomodationMedia {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name = "id")
private Long id;
#Column(name = "id_accomodation")
private Long idAccomodation;
#Column(name = "is_master")
private boolean isMaster;
#Lob
#Column(name = "media")
private byte[] media;
private String description;
private Date time_stamp;
public AccomodationMedia() {
}
...............................................................
...............................................................
...............................................................
// GETTER AND SETTER METHODS
...............................................................
...............................................................
...............................................................
}
The instance of this class represents the photo associated to an accomodation (an hotel)
So as you can see in the prvious code snippet I have this field :
#Column(name = "id_accomodation")
private Long idAccomodation;
that contains the id of an accomodation (the id of an hotel on my database).
I also have this boolean field that specify if an image is the master image or not:
#Column(name = "is_master")
private boolean isMaster;
So, at this time, in my repository class I have this method that should return all the images associated to a specific hotel:
#Repository
public interface AccomodationMediaDAO extends JpaRepository<AccomodationMedia, Long> {
List<AccomodationMedia> findByIdAccomodation(Long accomodationId);
}
I want to modify this method passing also the boolean parameter that specify if have to be returned also the master image or only the images that are not master.
So I tryied doing in this way:
List<AccomodationMedia> findByIdAccomodationAndIsMaster(Long accomodationId, boolean isMaster);
but this is not correct because setting to true the isMaster parameter it will return only the master image (because it is first selecting all the Accomodation having a specific accomodation ID and then the one that have the isMaster field setted as true).
So, how can I correctly create this query that use the isMaster boolean parameter to include or exclude the AccomodationMedia instance that represent my master image?
I know that I can use also native SQL or HQL to do it but I prefer do it using the "query creation from method names"
I don't have how to test this, but essentially your final query should be:
id_accomodation = ?1 AND (is_master = ?2 OR is_master = false)
So I would try the following method signature:
findByIdAccomodationAndIsMasterOrIsMasterFalse(Long accomodationId, boolean isMaster);
I would go with two methods one for isMaster true, while second for false value like this:
List<AccomodationMedia> findByIdAccomodationAndIsMasterFalse(Long accomodationId);
List<AccomodationMedia> findByIdAccomodationAndIsMasterTrue(Long accomodationId);
Change your acommodation id as accomodationId instead of idAccomodation. When you write findByIdAccomodationAndIsMaster spring confusing findByIdAccomodationAndIsMaster
Try this this convention
#Column(name = "accomodation_id")
private Long accomodationId;
I want to use spring data with mongodb and want to implement a one to many relationship using document reference.
db should look like this:
{
_id = 123451232
"countryName":"India",
"status":"true",
"meetings":[123451233, 123451234]
}
{
_id = 123451233
"countryName":"china",
"status":"true"
}
{
_id = 123451234
"countryName":"china",
"status":"true"
}
TO achieve this i used dbRef
country model
#Document(collection = "country")
public class Country {
#Id
#Field("country_id")
private String countryId;
#Field("country_name")
#Indexed
private String countryName;
#Field("status")
private boolean status = true;
#DBRef
private List<Country> meetings= new ArrayList<Country>();
// getters and setters
i got an error
HTTP Status 500 - Request processing failed; nested exception is org.springframework.data.mapping.model.MappingException: Cannot create a reference to an object with a NULL id.
I have an m:n connection in my MongoDB, MessageUserConnection is the class between User and Message.
Now I will get all MessageUserConnections where MessageUserConnection#confirmationNeeded is true, read is false and Message#receiveDate is not older than the last week.
Is there any possibility to do this with Spring Data?
Thanks a lot!
public class MessageUserConnection {
#Id
private String id;
#DBRef
private User userCreatedMessage;
#DBRef
private Message message;
private Boolean confirmationNeeded;
private Boolean read;
}
public class Message {
#Id
private String id;
private String title;
private String message;
private DateTime receiveDate;
}
[EDIT]
I have tried it by my own:
#Query("FROM MessageUserConnection AS muc WHERE muc.confirmationNeeded = ?0 AND muc.message.receiveDate = ?1")
List<MessageUserConnection> findMessageUserConnectionByConfirmationNeededAndReceiveDate(final Boolean confirmationNeeded, final DateTime receiveDate);
and I get the following exception:
Caused by: com.mongodb.util.JSONParseException:
FROM MessageUserConnection AS muc WHERE muc.confirmationNeeded = "_param_0" AND muc.message.receiveDate = "_param_1"
Does anyone know what I am doing wrong here?
Thanks a lot!
[EDIT]
I run into another problem. My query currently looks like this.
#Query("{$and : [{'confirmationNeeded' : ?0}, {'message.receiveDate' : ?1}]}")
where confirmationNeeded is a boolean and message.receiveDate is Joda#DateTime. With this query I get the following exception:
org.springframework.data.mapping.model.MappingException: Invalid path reference message.receiveDate! Associations can only be pointed to directly or via their id property!
Does that mean that I only can join to message.id?
Thanks a lot!

I am getting this error:

I found that you'll get this error from JDO if you're using progaurd and progaurd renames your private fields. Adding a -keep to the progaurd config to keep the package with your Persistence Capable classes will fix it.
For example, if you keep all of your Persistence Capable classes in com.example.server.orm package you'd add this to progaurd.conf
-keep class com.example.server.orm.** {*;}
