  • liquibase

    Main Liquibase Source

    Project mention: springboot with stored procedures | | 2022-04-18

    You might gain some efficiency but lose maintainability. I have worked on codebases were SP are coded, tuned and inserted by and, but this is painful for testing and so on. Instead, use FlywayDB or Liquibase for configuration management of the DB, to handle the DB migrations including inserting the SPs. In Spring use the SimpleJdbcCallOperations interface to call the SPs (with the concrete implementation class being SimpleJdbc), that way it is easy to mock or stub the database calls for unit testing. Use the unit testing framework that works best with your database to test your SPs, e.g. for Oracle see
