当没有要迁移的迁移时可以防止beforeMigrate回调脚本运行,因为该模式已经是最新的吗?在迁移之前防止迁移到最新模式
下面的代码(在应用程序启动时执行): -
Flyway flyway = new Flyway();
flyway.setDataSource(url, user, password);
flyway.setLocations(scriptsLocations);
flyway.setPlaceholders(placeHolders);
flyway.setBaselineVersionAsString("7.0");
flyway.setBaselineOnMigrate(true);
flyway.migrate();
根据日志迁徙路线运行beforeMigrate回调决定架构之前是最新的,并且没有迁移到运行。
INFO: Flyway 4.0.3 by Boxfuse
INFO: Database: jdbc:oracle:thin:... (Oracle 11.2)
INFO: Successfully validated 8 migrations (execution time 00:00.023s)
INFO: Executing SQL callback: beforeMigrate
INFO: Current version of schema "...": 7.0.7
INFO: Schema "..." is up to date. No migration necessary.
想要beforeMigrate回调仅在需要迁移时运行。
