How to fix "ORA-00942: table or view does not exist" with multiple databases in spring boot? - spring-boot

Question

I am trying to configure multiple datasources with spring boot, postgres will be my primary db and oracle will be the secondary one. I have my configuration as given the code. Whenever I am trying to make the application up I am getting the following error.

Removed the url, username and password from properties just for the question.
The packages for domain entity and repositories are empty time being.
When I am configuring them separately(one at a time) using the same code , it works, but together it doesn't work.
For oracle jdbc driver I have included only 1 jar i.e:ojdbc8.jar

Answer 1

try using #qualifier oracle datasource configuration and in class where you are autowiring this oracle instance.
