Spring JPA + MongoDB cross-store is not persisting properties of the document part

[stefano.cancedda]

Hi,

Still trying to integrate Spring data JPA and mongo with crossstore functionalities, but without success until now

My simplest case is to save a map of String/String in a Object (very close to the example in the documentation) :

public class ServiceDataFolder implements Serializable {

	private static final long serialVersionUID = 1L;
	private boolean required = false;
	private Map<String, String> questionari;

	public Map<String, String> getQuestionari() {
		return questionari;
	}

	public void setQuestionari(Map<String, String> questionari) {
		this.questionari = questionari;
	}

	public ServiceDataFolder addQuestionnaire(String title, String value) {
		this.questionari.put(title, value);
		return this;
	}

	public boolean isRequired() {
		return required;
	}

	public void setRequired(boolean required) {
		this.required = required;
	}


	@Override
	public String toString() {
               ...
	}

}

One of my worries about cross-store support is the constriction to use this kind of "wrapped objects" also when are not necessary, but ok ...
The object is java plain with no MongoDB annotations (as i seen in the docs it must no be annotated with @Document, @Index, etc) and used as a direct reference by the jpa entity:

package org.novaworks.legal.model;

import java.util.Map;
import java.util.Map.Entry;

import javax.persistence.Entity;
import javax.persistence.ManyToOne;
import javax.persistence.Table;
import javax.validation.constraints.NotNull;

import org.hibernate.annotations.Cache;
import org.hibernate.annotations.CacheConcurrencyStrategy;
import org.hibernate.validator.constraints.NotEmpty;
import org.novaworks.legal.model.document.ServiceDataFolder;
import org.springframework.data.mongodb.crossstore.RelatedDocument;


@Entity
@Table(name = "SERVIZI")
@Cache(region="long_lived", usage = CacheConcurrencyStrategy.READ_WRITE) 
public class Service extends AbstractPersistentEntity { //abstract contains ID, Version and other common stuff ...

	private static final long serialVersionUID = 1L;
	
	@NotEmpty
	private String code;
	@NotEmpty
	private String name;
	@NotEmpty
	private String description;
	
	@ManyToOne(optional = false)
	private ServiceGroup serviceGroup;
	
	@RelatedDocument
	ServiceDataFolder infos;
	
	@NotNull
	private Double price;
	
	private String workflowID;
	
	
	public String getWorkflowID() {
		return workflowID;
	}
	public void setWorkflowID(String workflowID) {
		this.workflowID = workflowID;
	}
	public ServiceGroup getGruppo() {
		return gruppo;
	}
	public void setGruppo(ServiceGroup gruppo) {
		this.gruppo = gruppo;
	}
	public ServiceDataFolder getInfos() {
		return infos;
	}
	public void setInfos(ServiceDataFolder infos) {
		this.infos = infos;
	}

       ... other getters/setters

}

Entity are persisted through interface extending JpaRepository<Service, String> using her save method. After a call to save, changes to entity are committed and a mongoDB entry related to Service entity is created but properties of ServiceDataFolder are not stored!
Specifically the property "questionary" is created but empty (no boolean property "required" is no "infos" collection property):

{
	"_id" : ObjectId("4fc77b323004f9b4be7690cc"),
	"_entity_id" : "1483a6b2-a8aa-407a-9844-fa6d18eefb06",
	"_entity_class" : "org.novaworks.legal.model.Service",
	"_entity_field_name" : "questionari",
	"_class" : "org.novaworks.legal.model.document.ServiceDataFolder",
	"questionari" : {
		
	},
	"_entity_field_class" : "org.novaworks.legal.model.document.ServiceDataFolder"
}

Transactions boundaries are correctly generated (i'm using Atomikos standalone JTA transaction-manager): i see two partecipant registrations (probably one for the EntityManager and another one for Mongo connections?).

For the sake of completion the following is the log after a save invocation:

thanks to anyone will give me any help!

Any help?
I'm stucked here. It's seems strange that cross-store persistence is working bad in that way :-(

Oliver: need to open a jira issue?
