Once the first connection is established to the database, Flyway will create a flyway_schema_history table to track the already applied database scripts with their checksum. The files are located in src/test/resources and the Source in src/test/java. With the Flyway dependency on the classpath, Spring Boot will initialize everything for you. staging, test, dev …).įor your database scripts, you should rely only on Flywayand write versioned migration scripts within your codebase ( src/main/resources/db/migration is the default folder): You also won't get information about the current database schema version of an environment (e.g. This might be a valid option for pet projects, but not for enterprise applications in production as you can't control the automatic migration process in detail. ![]() With these properties, you could update and migrate your database schema with Hibernate directly.
