Spring Boot + MongoDB Lightweight Migration

Annotation-driven migration runner: discover @MongoMigration methods on MigrationScript-implementing beans, execute in order, record results in a {prefix}_migrations collection so already-run migrations are skipped.

When to use

Spring Boot + MongoDB project that needs versioned schema/data changes.
Want to avoid the footprint of Mongock / Flyway-for-Mongo.
Idempotent, startup-triggered migrations are acceptable.

Steps

Create 4 infra files: @MongoMigration annotation, MigrationScript marker interface, MongoMigrationConfig (collects beans), MongoMigrationRunner (@EventListener(ApplicationReadyEvent.class) discovers + runs + records).
Convention: one V{nnn}_{Desc}.java per migration, @Component implements MigrationScript, annotate method with .
