Spring Boot Migrator (SBM) aims to help developers upgrade or migrate to Spring Boot by providing recipes for automated migrations.
https://github.com/spring-projects-experimental/spring-boot-migrator
Download the latest release outside of the project's folder to migrate, eg to the parent folder:
https://github.com/spring-projects-experimental/spring-boot-migrator/releases
Start SBM:
java -jar spring-boot-migrator.jar
Scan your application:
migrator:> scan myapp_docback
- boot-2.7-3.0-dependency-version-update [🤖]
-> Bump spring-boot-starter-parent from 2.7.x to 3.0.0-M3
- boot-2.7-3.0-upgrade-report [🤖]
-> Create a report for Spring Boot Upgrade from 2.7.x to 3.0.0-M3
Generate a report first
myapp_docback:> apply boot-2.7-3.0-upgrade-report
Applying recipe 'boot-2.7-3.0-upgrade-report'
[X] Create report
Action [SpringBoot30UpgradeReport] 'Create report' failed: Cannot invoke "org.openrewrite.java.tree.TypeTree.getType()" because the return value of "org.openrewrite.java.tree.J$MethodDeclaration.getReturnTypeExpression()" is null
Details of the error have been omitted. You can use the stacktrace command to print the full stacktrace.
Run the migration
myapp_docback:> apply boot-2.7-3.0-dependency-version-update
Applying recipe 'boot-2.7-3.0-dependency-version-update'
[ok] Add Spring Boot milestone repository.
[ok] Add Spring Boot milestone plugin repository.
[X] Add Spring Milestone Repository and bump SpringBoot to 3.0.0-M3
