Customize Your Provider

All providers have a local default implementation. You can provide a Spring bean to replace it.

Auth Provider

Use JustAuth implement it. You can return an AuthRequest to use your authentication server. You can learn more about JustAuth and how to use it to implement authentication.

public interface AuthRequestProvider extends BiFunction<String, AuthConfig, Optional<AuthRequest>> {
}

The default implementation is DefaultAuthRequestProvider, which includes all AuthRequest in AuthDefaultSource.

Email Message Provider

public interface AuthMimeMessagePreparationProvider {
    AuthMimeMessagePreparator ofSignup(String email, MessageParam messageParam);

    AuthMimeMessagePreparator ofResetPassword(String email, MessageParam messageParam);

    AuthMimeMessagePreparator ofEmailChange(String email, MessageParam messageParam);
}

The default implementation is DefaultAuthMimeMessagePreparationProvider, which is the same as the default message in Supabase.

Storage Provider

public interface S3Provider<T> {

    ObjectMetadata putObject(Bucket bucket,
                             String key,
                             String cacheControl,
                             String mineType, byte[] fileByte);

    ResponseEntity<T> downloadObject(Bucket bucket, String key, String download, ObjectMetadata objectMetadata);
}

The default implementation is DefaultS3Provider, which saves objects to ./s3/bucketName/fileMd5value.
