I am getting following problem when trying to save an Entity into MongoDB
database.
I am using Spring
CrudRepository
An my code looks as follow:
UserDocument user = processUser();
userRepository.save(user);
This is the error I am getting:
java.lang.IllegalStateException: Could not obtain identifier from UserDocument(id=null, ownerId=..., ...)!
at o.s.d.m.TargetAwareIdentifierAccessor.getRequiredIdentifier(TargetAwareIdentifierAccessor.java:47)
at o.s.d.m.c.EntityOperations$MappedEntity.getId(EntityOperations.java:466)
... 53 frames excluded
UserDocument class:
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.EqualsAndHashCode;
import lombok.NoArgsConstructor;
import lombok.experimental.Accessors;
import lombok.experimental.SuperBuilder;
import org.bson.types.ObjectId;
import org.springframework.data.annotation.Id;
import org.springframework.data.mongodb.core.index.CompoundIndex;
import org.springframework.data.mongodb.core.index.CompoundIndexes;
import org.springframework.data.mongodb.core.mapping.Document;
@Data
@EqualsAndHashCode(callSuper = true)
@NoArgsConstructor
@AllArgsConstructor
@Accessors(chain = true)
@SuperBuilder
@Document(collection = UserDocument.COLLECTION)
public class UserDocument extends BaseDocument<ObjectId> {
public static final String COLLECTION = "users";
@Id
private ObjectId id;
.....
}

I struggled with this too. In my case, the problem was the @Version
field in the object I was trying to save was set to 0. After I set it to null I didn't have this anymore.
I noticed the methods in the trace getQueryForVersion, doSaveVersioned...

For anyone that is struggling with this problem - in my case it was problem with mapstruct
Mapper
that as a side effect was populating fields in super class:
import org.springframework.data.annotation.CreatedDate;
import org.springframework.data.annotation.LastModifiedDate;
import org.springframework.data.annotation.Version;
@Data
@NoArgsConstructor(access = AccessLevel.PROTECTED)
@AllArgsConstructor(access = AccessLevel.PROTECTED)
@Accessors(chain = true)
@SuperBuilder
public abstract class BaseDocument<ID extends Serializable> implements Persistable<ID> {
@Version
private Long revision;
@CreatedDate
private Instant createdDateTime;
@LastModifiedDate
private Instant lastModifiedDateTime;
@Override
public boolean isNew() {
return isNull(createdDateTime);
}
}
So make sure these fields are null
when you are saving a new entity!
