Flyway迁移和休眠上下文、执行顺序

Question

我正在使用 spring 引导，默认配置带有 flyway 和休眠。我想知道执行顺序。根据文档 Flyway checks the version of the database and applies new migrations automatically before the rest of the application starts.

在哪里可以找到确认该声明的源代码？执行顺序在哪里确定？

Answer 1

Spring 引导使用 FlywayMigrationInitializer bean（它以高阶（ oder = 0 ）实现 InitializingBean ），因此afterPropertiesSet，其中包含飞路迁移功能：

@Override
public void afterPropertiesSet() throws Exception {
    if (this.migrationStrategy != null) {
        this.migrationStrategy.migrate(this.flyway);
    }
    else {
        this.flyway.migrate();
    }
}

将执行 Flyway.java#migrate() 中的逻辑，其中

Starts the database migration. All pending migrations will be applied in order.Calling migrate on an up-to-date database has no effect.

你可以参考Flyway.java of javadoc and FlywayMigrationInitializer.javajavadoc
