本文整理了Java中com.networknt.config.Config类的一些代码示例，展示了Config类的具体用法。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。Config类的具体详情如下：
包路径：com.networknt.config.Config
类名称：Config

Config介绍

[英]A injectable singleton config that has default implementation based on FileSystem json files. It can be extended to other sources (database, distributed cache etc.) by providing another jar in the classpath to replace the default implementation.

Config files are loaded in the following sequence: 1. resource/config folder for the default 2. externalized directory specified by light-4j-config-dir

In docker, the config files should be in volume and any update will be picked up the next day morning.
[中]可注入的单例配置，具有基于文件系统json文件的默认实现。通过在类路径中提供另一个jar来替换默认实现，可以将其扩展到其他源（数据库、分布式缓存等）。
配置文件按以下顺序加载：1。默认2的资源/配置文件夹。light-4j-config-dir指定的外部化目录
在docker中，配置文件应该在卷中，任何更新都将在第二天早上获取。
