    接口 EntitySubscriberInterface<Entity>

    Classes that implement this interface are subscribers that subscribe for the specific events in the ORM.

    interface EntitySubscriberInterface<Entity = any> {
        afterInsert?(event: InsertEvent<Entity>): void | Promise<any>;
        afterLoad?(entity: Entity, event?: LoadEvent<Entity>): void | Promise<any>;
        afterQuery?(event: AfterQueryEvent<Entity>): void | Promise<any>;
        afterRecover?(event: RecoverEvent<Entity>): void | Promise<any>;
        afterRemove?(event: RemoveEvent<Entity>): void | Promise<any>;
        afterSoftRemove?(event: SoftRemoveEvent<Entity>): void | Promise<any>;
        afterTransactionCommit?(event: TransactionCommitEvent): void | Promise<any>;
        afterTransactionRollback?(
            event: TransactionRollbackEvent,
        ): void | Promise<any>;
        afterTransactionStart?(event: TransactionStartEvent): void | Promise<any>;
        afterUpdate?(event: UpdateEvent<Entity>): void | Promise<any>;
        beforeInsert?(event: InsertEvent<Entity>): void | Promise<any>;
        beforeQuery?(event: BeforeQueryEvent<Entity>): void | Promise<any>;
        beforeRecover?(event: RecoverEvent<Entity>): void | Promise<any>;
        beforeRemove?(event: RemoveEvent<Entity>): void | Promise<any>;
        beforeSoftRemove?(event: SoftRemoveEvent<Entity>): void | Promise<any>;
        beforeTransactionCommit?(
            event: TransactionCommitEvent,
        ): void | Promise<any>;
        beforeTransactionRollback?(
            event: TransactionRollbackEvent,

      For backward compatibility this signature is slightly different from the others. event was added later but is always provided (it is only optional in the signature so that its introduction does not break compilation for existing subscribers).
