本文整理了Java中javax.cache.Cache.getConfiguration()方法的一些代码示例，展示了Cache.getConfiguration()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。Cache.getConfiguration()方法的具体详情如下：
包路径：javax.cache.Cache
类名称：Cache
方法名：getConfiguration

Cache.getConfiguration介绍

[英]Provides a standard way to access the configuration of a cache using JCache configuration or additional proprietary configuration.

The returned value must be immutable.

If the provider's implementation does not support the specified class, the IllegalArgumentException is thrown.
[中]提供使用JCache配置或其他专有配置访问缓存配置的标准方法。
返回的值必须是不可变的。
如果提供程序的实现不支持指定的类，则引发IllegalArgumentException。
