summary
Spring Boot Migrator (started Q4 2020, OSS since March 2022) runs on OpenRewrite and provides runnable recipes that scan a repo, apply actions, and commit each migration step. Demo converts an EJB stateless bean to Spring by removing @Stateless, adding @Service and importing a bean name from ejb-jar.xml, with in-memory tests using a TestProjectContext and injected Java parser. Recipes appear as Java or yaml recipes and the migrated app boots as Spring Boot.
