@StorageProp:单向绑定(适合全局配置读取) @StorageLink:双向绑定(如用户登录状态全局同步) 核心特性: 支持复杂类型(Map/Set/Date等,需配合@Observed装饰器) 提供connectAPI实现类型安全的状态访问 与PersistentStorage深度集成 仅支持主线程访问,非UI线程需通过Worker线程处理 避免存储超过2MB的大型对象 高频更新数据建议...
Persistent data is any data stored on a non-volatile storage medium that remains accessible for long-term use until it is purposefully deleted or overwritten.
2 解决方法 2.1 持久化失败原因 经过反复阅读官方文档与论坛,定位原因是对PersistentStorage数据持久化的不理解,导致接口调用位置错误或接口使用错误,导致PersistentStorage的持久化运行错,从而导致数据持久化失败。 2.2 解决过程描述 在开始之前,首先附上PersistentStorage的官方文档,方便大家阅读,同时,后面的很多图片将会从...
