mysql - JSON data not include entity -


i developing restful api.i have 2 entities. user , userrole. when send request api user, gives me

{     "id": 11,     "name": "mert",     "username": "zbrave",     "password": "$2a$10$n0eqniuikwcy9etq1rdau.xeelcyeo7kukkfoinisk/9f7gw6eb0w",     "email": "asd",     "photo": "",     "enabled": true,     "roles": [         {             "id": 1,             "role": "admin"         }     ],     "online": false } 

when send request userrole, returns

[     {         "id": 1,         "role": "admin"     } ] 

but in userrole entity, there user entity. json not return user entity.

public class userrole implements serializable {     ...     @manytoone(targetentity = user.class, cascade = cascadetype.all, fetch = fetchtype.eager)     @joincolumn(name = "user_id")     @jsonbackreference     private user user;     ...     }    public class user implements serializable {     ...     @onetomany(targetentity = userrole.class, mappedby = "user", cascade = cascadetype.all, fetch = fetchtype.eager)     @jsonmanagedreference     private list<userrole> roles;     ..     } 

i can user roles user entity's json. not reverse. there wrong things ? help.

you using @jsonbackreference/ @jsonmanagedreference yeah expected behavior , side in jsonbackreference wont serialized, necessary avoid infinite recursion since jackson keep serializing each side of relation reference in other side, why need skip serializing 1 side

there nice solution this, mentioned in link , idea generate reference parent entity, if serializing user, have user->role->[reference user instead of user], need annotate entities @jsonidentityinfo

@jsonidentityinfo(generator=objectidgenerators.uuidgenerator.class, property="@id") public class userrole implements serializable {   @jsonidentityinfo(generator=objectidgenerators.uuidgenerator.class, property="@id") public class user implements serializable { 

so , remove @jsonbackreference/ @jsonmanagedreference
