本文整理了Java中com.j256.ormlite.dao.Dao.setObjectCache()方法的一些代码示例，展示了Dao.setObjectCache()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Dao.setObjectCache()方法的具体详情如下：
包路径：com.j256.ormlite.dao.Dao
类名称：Dao
方法名：setObjectCache

Dao.setObjectCache介绍

[英]Same as #setObjectCache(boolean) except you specify the actual cache instance to use for the DAO. This allows you to use a ReferenceObjectCache with SoftReference setting, the LruObjectCache, or inject your own cache implementation. Call it with null to disable the cache.
[中]与#setObjectCache（布尔值）相同，只是指定要用于DAO的实际缓存实例。这允许您使用带有SoftReference设置的ReferenceObjectCache、LruObjectCache或注入您自己的缓存实现。使用null调用它以禁用缓存。
