Issue
Background: spring + mybatis + oracle data source
Requirement: support postgreSQL data source exchange with minimum code change
Example:
Current: controllerA -> ServiceA -> daoA -> A.xml (oracle)
Now need: we can configure use oracele/postgreSQL database source
If configure use postgreSQL: controllerA -> ServiceA -> daoA -> A.xml (postgreSQL)
More:
Same controllerA、ServiceA for same business logic
Differenct DaoA、A.xml for oracle and postgreSQL mybatis sql implementation
DaoA is better to be same if it can be.
The data and sql logic is the same for oracle and postgreSQL, just need a congfiguration to change to use oracle/postgreSQL implementation.
How to implement it?
Solution
Solution is on the comments: use databaseIdProvider technique will work
