Save the file + +5. Restart the application to verify it still works without the repair strategy + +## Why Remove the Bean? + +The repair strategy should only run **once** to fix the checksum mismatch. Keeping it in the code means: +- It will run on every application startup (unnecessary overhead) +- It could mask future migration problems +- It's not needed once the database schema history is corrected + +## What If It Doesn't Work? + +If the application fails to start with this fix: + +1. Check the error logs for specific Flyway errors +2. Verify your database connection settings in `application.yml` +3. Ensure PostgreSQL is running and accessible +4. Check that you have the correct database credentials + +## Root Cause + +The issue occurred because two migration files were created with the same version number (V14): +- One for creating USDA food tables +- One for seeding default API keys + +Flyway expects each migration version to be unique and immutable. When the content of a migration changes, its checksum changes, causing validation failures. + +## Long-term Solution + +To prevent this in the future: +1. Always use unique version numbers for migrations +2. Never modify existing migration files after they've been applied +3. Use incremental version numbers (V16, V17, V18, etc.) +4. Consider renaming one of the V14 files to V16 or higher in a future clean migration diff --git a/backend/src/main/java/com/fitnessapp/backend/FitnessAppApplication.java b/backend/src/main/java/com/fitnessapp/backend/FitnessAppApplication.java index f2d96d11..feda8a99 100644 --- a/backend/src/main/java/com/fitnessapp/backend/FitnessAppApplication.java +++ b/backend/src/main/java/com/fitnessapp/backend/FitnessAppApplication.java @@ -2,8 +2,10 @@ import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; +import org.springframework.boot.autoconfigure.flyway.FlywayMigrationStrategy; import org.springframework.boot.context.properties.ConfigurationPropertiesScan; import org.springframework.cache.annotation.EnableCaching; +import org.springframework.context.annotation.Bean; import org.springframework.data.jpa.repository.config.EnableJpaRepositories; @SpringBootApplication @@ -22,6 +24,24 @@ public class FitnessAppApplication { public static void main(String[] args) { SpringApplication.run(FitnessAppApplication.class, args); } + + /** + * Temporary Flyway migration strategy to repair checksum mismatches. + * This bean performs a Flyway repair operation before running migrations, + * which fixes any checksum inconsistencies in the flyway_schema_history table. + * + * IMPORTANT: This bean should be removed after the application starts successfully + * and the database schema history is repaired.
