Spring Configuration

Use @ConditionalOnModuleEnabled to conditionally load beans:

@Configuration
@ConditionalOnModuleEnabled("redis")
public class RedisConfig {
    // Only loaded when modules.redis.enabled=true
}

application.yml

modules:
  postgresql:
    enabled: true
  redis:
    enabled: ${MODULE_REDIS_ENABLED:false}
  kafka:
    enabled: ${MODULE_KAFKA_ENABLED:false}
  rabbitmq:
    enabled: ${MODULE_RABBITMQ_ENABLED:false}
  oauth2:
