本文整理了Java中io.helidon.config.Config.asMap()方法的一些代码示例，展示了Config.asMap()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.asMap()方法的具体详情如下：
包路径：io.helidon.config.Config
类名称：Config
方法名：asMap

Config.asMap介绍

[英]Transform all leaf nodes (values) into Map instance.

Fully qualified key of config node is used as a key in returned Map. #detach() config node before transforming to Map in case you want to cut current Config node key prefix.

Let's say we work with following configuration:

app: 
name: Example 1 
page-size: 20 
logging: 
app.level = INFO 
level = WARNING

Map app1 contains two keys: app.name, app.page-size.

Map app1 = config.get("app").asMap();

#detach() app config node returns new Config instance with "reset" local root.

Map app2 = config.get("app").detach().asMap();

Map app2 contains two keys without app prefix: name, page-size.
[中]将所有叶节点（值）转换为贴图实例。
config节点的完全限定键用作返回映射中的键#如果要剪切当前配置节点键前缀，请在转换为映射之前分离（）配置节点。
假设我们使用以下配置：

app: 
name: Example 1 
page-size: 20 
logging: 
app.level = INFO 
level = WARNING

地图应用程序1包含两个键：应用程序。名称，应用程序。页面大小

Map app1 = config.get("app").asMap();

#detach（）app config节点返回具有“reset”本地根的新配置实例

Map app2 = config.get("app").detach().asMap();

Map app2包含两个不带应用前缀的键：名称、页面大小。
