As I was just getting started with Aura trying to get my Spring Boot app up and running, I discovered that the Connect - Spring Boot page could use some more info such as the versions of Spring Boot Data & Neo4j OGM that work properly.
In my case, my app was throwing a
ClassNotFoundException: org.neo4j.driver.util.BookmarkUtil
when I attempted to access the database. I was stumped until I discovered this page: https://medium.com/neo4j/using-neo4j-aura-from-java-and-spring-boot-f1c1684894f8
It turned out my version of Neo4j OGM was slightly out of date (by just a couple of patch versions!). I upgraded to the versions mentioned in the article and the problem went away.
Others might be saved some trouble if the Connect - Spring Boot page mentioned the compatible Spring Data & Neo4j OGM versions, or perhaps included a link to the above mentioned article.
