Dies ist, wo ich verwirrt habe. Ich habe Postgres-Treiber bereits eingerichtet usw., aber in den Fehlerprotokollen habe ich gesehen, dass Wildfly versucht, sich mit dem h2-Treiber zu verbinden.
Wenn ich die hbm2ddl.auto zu 'create' änderte, kann ich im Protokoll sehen, dass die Tabelle 'app_user' erstellt, aber nicht in meiner postgresql-Tabelle, so dass ich vermute, dass es stattdessen in H2 erstellt wird.
Bitte helfen.
Wo ist der Code, an dem Sie angeben, welche Persistenzeinheit verwendet werden soll? (@PersistenceContext (unitName = "MyUnit")) ... Ich habe auch die Verbindung in wildfly eingerichtet und daher keine Verbindungszeichenfolge, Benutzername und Passwort in persistence.xml, nur den Namen der Verbindung. (Andere Eigenschaften im Ruhezustand sind in persistence.xml angegeben, wie Dialekt, Formatierung von sql und hibernate.hbm2ddl.auto. Aber zuerst, versuchen Sie einfach, EntityManager in Ihren Diensten mit der obigen Anmerkung zu kommentieren, vielleicht reicht das. –
Hi @jonmartinsolaas, In meinem Log scheint es, als würde ich "com.example.flow.persistence.jpa" als meine Persistenz-Einheit wählen, was meine einzige Persistenz-Einheit ist. – VHanded
Ich denke, es ist * sehr * seltsam, dass h2 benutzt wird, wenn du postgresql Die Persistenzeinheit ist tatsächlich mit Ihrem EntityManager verbunden.Wenn persistence.xml gelesen wird, protokolliert wildfly die dort gefundenen Persistenzeinheiten.Um sie jedoch tatsächlich in Ihrem Code zu verwenden, müssen Sie Ihren EntityManager auch darauf verweisen, das wird nicht automatisch geschehen Versuchen Sie, Treiber und Verbindung wie von Nicholas unten beschrieben einzurichten, und versehen Sie dann Ihren EntityManager mit dem @PersistenceContext Annotation- und UnitName-Parameter. (Ich glaube, ich habe viel klarere Fehlermeldungen erhalten, wenn ich hatte mit Glassfish und Verbindungen zu kämpfen ...) –
