java - Spring JPA Repository ony fetches id instead of full object when it's already in result -

in springboot rest application, have 2 classes follows:

user.java , message.java.

message has -from- field (user) , -to- of type (user).

so i've made this:

in user.java:

@entity @jsonidentityinfo(generator=objectidgenerators.propertygenerator.class,  property="id")  public class user { @id @generatedvalue(strategy = generationtype.identity) private integer id;  private string firstname; private string lastname; private string email;  @jsonignore @onetomany(mappedby = "to") private list<message> receivedmessages;  @onetoone @joincolumn(name = "type") private usertype type; 

in message.java:

@entity public class message {  @id @generatedvalue(strategy= generationtype.identity) private integer id;  @manytoone @joincolumn(name = "from_user_id") private user from;  @manytoone @joincolumn(name = "to_user_id") private user to;  private string subject; private string message; private date senttime; private date readtime;  private integer replyto;  (setters & getters, etc) 

and apparently works! -but- let's have 3 messages, , first 2 of them went sent same user, first of 2 comes full user object , seconds it's id, follows:

[ {     "id": 16,     "from": {         "id": 1,         "firstname": "ale",         "lastname": null,         "email": "axfeea@gmail.com",         "username": null,         "password": "123456",         "avatar": "https://..............jpg",         "type": null     },     "to": 1,     "subject": "sub",     "message": "hola",     "senttime": null,     "readtime": null,     "replyto": null }, {     "id": 17,     "from": {         "id": 2,         "firstname": "carlos",         "lastname": "perez",         "email": "efefe@fefe.com",         "username": null,         "password": "fe",         "avatar": "https://..................jpg",         "type": null     },     "to": 1,     "subject": "sub1",     "message": "chau",     "senttime": null,     "readtime": null,     "replyto": null }, {     "id": 18,     "from": 2,     "to": 1,     "subject": "efefae",     "message": "oooook",     "senttime": 1503249653000,     "readtime": null,     "replyto": null } 

]

and if 3rd message comes non-repeated user comes full object.

i need full object come always.

and -btw- in database , same way.

any ideas?

thank in advance!

since have specified annotation jsonidentityinfo, jackson serializes objects in resulting json.

the javadoc of annotation specifies:

in practice done serializing first instance full object , object identity, , other references object reference values.

so if don't want behaviour, remove annotation.
