Multiple Databases With Shared Entity Classes in Spring Boot and Java

Hello, everyone, It has been a few months since my last post. I have been busy traveling and relocating. In this post, I want to illustrate how a Spring Boot application can have multiple data sources with shared entity classes. The need for this arose in my current project where an in-memory database was needed for the high performance and a persistent database for storage.

In this blog post, I will use H2 for the in-memory database and Postgres for the persistent storage. I will setup up the application and show how the entities can be passed from one data source to another.
