类名称：ZoneRulesProvider
方法名：getRules

ZoneRulesProvider.getRules介绍

[英]Gets the rules for the zone ID.

This returns the latest available rules for the zone ID.

This method relies on time-zone data provider files that are configured. These are loaded using a ServiceLoader.

The caching flag is designed to allow provider implementations to prevent the rules being cached in ZoneId. Under normal circumstances, the caching of zone rules is highly desirable as it will provide greater performance. However, there is a use case where the caching would not be desirable, see #provideRules.
[中]获取区域ID的规则。
这将返回区域ID的最新可用规则。
此方法依赖于已配置的时区数据提供程序文件。这些都是使用ServiceLoader加载的。
缓存标志旨在允许提供程序实现防止在ZoneId中缓存规则。在正常情况下，缓存区域规则是非常可取的，因为它将提供更高的性能。但是，有一种情况下缓存是不可取的，请参见#provideRules。
