Hello Ashok, i have a problem statement - suppose i want to use 2 rdbms database one as primary and other as backup database so if i want to persist all entities to both database and retrieve the data only from primary database via repository how to configure, can you please help.
Can you please highlight how Transactions would work?
Very good explanation but username and password hard coded values how to do secret
Why @primary is used in db1 configuration class and not in db2 congratulation class
Problem is i am able to connect using this but using connection pool i am unable to do it using jndi-name
In case of same class name , User which is defined in two different
com.ashokit.read.User
Another one is
com.ashokit.write.User
In this case database understand which User class to use
You are writing in spring boot 2.x application?

I tried your solution but you don't show what's in the entities package. Other classes are also hidden. Do you have a github link where we can get this code and try this? Without the link, the solution doesn't help.

This should not work as there are conflicting names used. Same name used in the same Spring Context in multiple places. Application (Spring framework) will present an error and would not start.
sir can you please share code here. getting compilation errors while creating Builder object

I Tried this already but what if my database is totally dynamic and i need to switch the database in runtime? For example my conn info comes from my admin table where all my clients database conn info are stored. Which ever client uses the appplication it should switch the database on runtime. I was not able to acheive this using dynamic datasource routing and stuffs. Can you help me with that ?
