SpringBoot + Hibernate + Postgres

Ich versuche, einen Wert (http://localhost:8080/create?name=name1&[email protected]) zu Postgres DB mit SpringBoot und Ruhezustand einfügen, aber im Protokoll sagt, wie es fügt, aber keine Datensätze eingefügt werden auch keine Ausnahme ist da.Bitte helfen Sie mir zu finden Problem.SpringBoot + Hibernate + Postgres

Können Sie auch fügen Sie Ihre Benutzerklasse

id bigint NOT NULL DEFAULT nextval('user_id_seq'::regclass)

Einige weitere Informationen über serielle Felder können in dieser Frage zu finden? Möglicherweise erhält der Benutzer keine ID? – Fortega

@Fortega danke für Ihre Antwort, bitte überprüfen Sie, dass ich die User.java beigefügt habe. – sunleo

Wie wird Ihr ID-Schlüssel in der Datenbank deklariert? – Berger

Wenn Sie ein serial oder ein bigserial Feld in einer Postgre Tabelle verwenden, ist es ein Auto-increment-Feld für das eine Sequenz automatisch erstellt wird.

Dies kann zu Problemen mit der Sequenz führen, die standardmäßig von Hibernate verwendet wird (hibernate_sequence), wenn verwendet wird.

Um das zu vermeiden, können Sie entweder verlassen sich auf die ID-Generator Serienfeld:

@Id 
@GeneratedValue(strategy=GenerationType.IDENTITY)

Oder Sie können die Folge (1) feststellen, dass die bigserial erzeugt hat (die es für dieses Beispiel nennen wir user_id_seq), und es in Ihren Anmerkungen angeben, damit Hibernate dieses direkt verwendet:

@Id 
@SequenceGenerator(name = "seqUser", sequenceName = "user_id_seq", allocationSize = 1) 
@GeneratedValue(generator = "seqUser", strategy = GenerationType.AUTO)

(1): in der Tabelle Skript, werden Sie wahrscheinlich so etwas wie die folgenden haben, können Sie den Namen der Sequenz von Postgre verwendet erzählen für das Inkrement (normalerweise ist es wie: Tabellenname _ Spaltenname _seq). PostgreSQL bigserial & nextval
