I have to create custom endpoint in App Dynamics for either java class/interface/annotation/abstract java class for MySQL, that would intercept mysql calls. Spring Boot is using JPA's CRUDRepository/JPARepository/Repository as an abstract layer to call vendor databases. Only class that implements them is SimpleRepository. JDBCTemplate is no longer used.

Now, when we have multiple datasources, I would like to pin the class/interface/abstract/annotation from MySQL side which is called internally by spring framework, specifically for saving/persisting/updating/deleting POJO entities. I would appreciate if somebody knows which class/interface is being called from MySQL side by spring repository interfaces mentioned above. Thanks a ton.
