Class SuperCacheServiceImpl<M extends SuperCacheManager<Entity>,Id extends Serializable,Entity extends SuperEntity<?>>

java.lang.Object

top.tangyh.basic.base.service.impl.SuperServiceImpl<M,Id,Entity>

top.tangyh.basic.base.service.impl.SuperCacheServiceImpl<M,Id,Entity>

Type Parameters:

M - Manager

Id - ID

Entity - 实体

All Implemented Interfaces:

SuperCacheService<Id,Entity>, SuperService<Id,Entity>

public abstract class SuperCacheServiceImpl<M extends SuperCacheManager<Entity>,Id extends Serializable,Entity extends SuperEntity<?>>
extends SuperServiceImpl<M,Id,Entity>
implements SuperCacheService<Id,Entity>

基于 CacheOps 实现的 缓存实现 默认的key规则： #{CacheKeyBuilder#key()}:id

1，getByIdCache：新增的方法： 先查缓存，在查db 2，removeById：重写 ServiceImpl 类的方法，删除db后，淘汰缓存 3，removeByIds：重写 ServiceImpl 类的方法，删除db后，淘汰缓存 4，updateAllById： 新增的方法： 修改数据（所有字段）后，淘汰缓存 5，updateById：重写 ServiceImpl 类的方法，修改db后，淘汰缓存
