Spring Boot Migrator (SBM)

Spring Boot Migrator (SBM) aims to help developers upgrading or migrating to Spring Boot by providing recipes for automated migrations.

How SBM works

A given codebase is scanned and a set of recipes gets evaluated against the codebase.
The list of applicable recipes is displayed and recipes can be selected from the list to be run against the codebase.
The recipes either apply automated migrations or guide users on their migration journey.

Getting started

• Download the latest release from here: Spring Boot Migrator Releases

• Start the application: java -jar spring-boot-migrator.jar

• In the CLI start by scanning the application scan <path-to-application>

• From the list of applicable recipes select the one you want to apply,
  e.g.: apply initialize-spring-boot-migration
  Spring Boot Migrator will now apply the migrations defined in the recipe to the codebase.

• To get help when using SBM use the help command

Warning

The OpenRewrite rewrite-java-11 module uses JDK internals and thus requires the project to run with JDK 11.

Building from source

• Clone the repository

• Change into root dir

• Run mvn clean install

• Find the jar in applications/spring-shell/spring-boot-migrator.jar

Warning

Some integration tests use Docker so you’ll need Docker to run them. You can pass the -DskipTests flag to the mvn command to ignore tests.
