Autowiring not working inside flyway callback methods

I am trying to flyway for the migration demo. In which I am able to migrate code. I have extended BaseFlywayCallback and I want to print migration info before and after each migration. I have code in other service class for printing info. I am auto wiring it but it is not working there. I have tried some other ways but nothing worth it.

  @Autorired
  PrintInfoService service

How can I do that?

Solution

The integration with flyway internally in spring boot is done by means of using FlywayAutoConfiguration

It has to create a Flyway bean on which it will register all callbacks found in the classpath.

I can't test this, but you I believe you have to:

Make sure that your callback is a spring bean
Make sure that spring boot scans your bean and create an instance of it during the initialization
Place a breakpoint in the FlywayAutoConfiguration's:

public Flyway flyway(FlywayProperties properties, DataSourceProperties dataSourceProperties,
                ResourceLoader resourceLoader, ObjectProvider<DataSource> dataSource,
                @FlywayDataSource ObjectProvider<DataSource> flywayDataSource,
                ObjectProvider<FlywayConfigurationCustomizer> fluentConfigurationCustomizers,
                ObjectProvider<JavaMigration> javaMigrations, ObjectProvider<Callback> callbacks)

... And make sure that your callback is in the list of beans recognized by spring.
