Description:

Parameter 0 of method entityManagerFactory in com.example.sse_chat_bot.config.PrimaryDataSourceConfig required a bean of type 'org.springframework.boot.orm.jpa.EntityManagerFactoryBuilder' that could not be found.

Action:

Consider defining a bean of type 'org.springframework.boot.orm.jpa.EntityManagerFactoryBuilder' in your configuration.

Spring is unable to autowire the EntityManagerFactoryBuilder.

Ich versuche, 2 Datenbanken in einer einzelnen Spring -Boot -Anwendung zu konfigurieren. Damit ich 2 separate Konfigurationsdateien für Postgres und Postgres Vector DB konfiguriert habe. < /P>
