[ { "@id": 1, "iduser": 1, "username": "well", "password": "12345", "expired": true, "locked": true, "enabled": true, "login": "well", "role": { "@id": 2, "idrole": 1, "role": "role_user" } }, { "@id": 3, "iduser": 2, "username": "bárbara", "password": "12345", "expired": true, "locked": true, "enabled": true, "login": "barbara", "role": { "@id": 4, "idrole": 2, "role": "role_admin" } } ]
why @id in json return?
i can't convert json object
how can solve this? what's wrong?
