mehrere Datenquelle mit Federverschluß JPA

Der Versuch, Dual- Datenquelle mit Feder Boot, aber es wäre viel schwerer als erster Gedanke scheint,mehrere Datenquelle mit Federverschluß JPA

versucht Tonnen von Tutorials und Anleitungen zu folgen, aber halten Sie Fehler mit meinem repos bekommen.

Wo ist Ihre StoreDbEntRepo-Bean? Kannst du es posten? –

@CletoGadelha hat den Repo hinzugefügt –

Ihr Hauptproblem ist: not a managed type: class com.anders.cphbusiness.entitiesModel.WagerBoard

Ihre StoreDbEntRepo werden mit "secondaryEM", werden aber mit WagerBoard Unternehmen die Repo zu erstellen.

Die WagerBoard-Entität gehört zum EntitysModel-Paket. Wenn Sie diese Einheit in Ihre StoreDbEntRepo verwenden möchten, um Ihren Bedarf das richtige Paket in Ihrem EntityManager zu scannen, ein Update von

.packages("com.anders.cphbusiness.storingModel")

.packages("com.anders.cphbusiness.storingModel","com.anders.cphbusiness.entitiesModel").

zu tun, aber wenn Sie nicht tun, verwenden Sie ein Entität, die zum storingModel-Paket gehört, um das StoreDbEntRepo-Objekt zu erstellen.

entitiesModel ist die Entitäten für primäre db und storingModel ist für sekundäre db –

Ok, aber Sie verwenden die WagerBoard-Entität in Ihre sekundäre db. –

Wenn Sie eine andere Entität des storingModel-Pakets in Ihrem StoreDbEntRepo verwenden, funktioniert es ohne Änderungen. Um die WagerBoard-Entität zu verwenden, müssen Sie sie jedoch scannen. –
