custom 模式和 database 模式可以同时存在吗？应该怎么配置？

目前引入两个包，就会冲突报错，找到了两个 ExecutionInstanceStorage

Failed to instantiate [com.alibaba.smart.framework.engine.SmartEngine]: Factory method 'constructSmartEngine' threw exception; nested exception is com.alibaba.smart.framework.engine.exception.EngineException: Duplicated bindKeyClass found interface com.alibaba.smart.framework.engine.instance.storage.ExecutionInstanceStorage for group common, because of duplicated annotation or init twice.

这是我的配置

[1725636955]

我理解应该是需要自定义 SimpleAnnotationScanner 的扫描路径，但是不知道需要哪些

[vavi]

目前不能同时在一个应用内部署2种模式
