本文整理了Java中org.springframework.beans.factory.config.YamlPropertiesFactoryBean类的一些代码示例，展示了YamlPropertiesFactoryBean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。YamlPropertiesFactoryBean类的具体详情如下：
包路径：org.springframework.beans.factory.config.YamlPropertiesFactoryBean
类名称：YamlPropertiesFactoryBean

YamlPropertiesFactoryBean介绍

[英]Factory for java.util.Properties that reads from a YAML source, exposing a flat structure of String property values.

YAML is a nice human-readable format for configuration, and it has some useful hierarchical properties. It's more or less a superset of JSON, so it has a lot of similar features.

Note: All exposed values are of type String for access through the common Properties#getProperty method (e.g. in configuration property resolution through PropertyResourceConfigurer#setProperties(Properties)). If this is not desirable, use YamlMapFactoryBean instead.

The Properties created by this factory have nested paths for hierarchical objects, so for instance this YAML

environments: 
dev: 
url: http://dev.bar.com 
name: Developer Setup 
prod: 
url: http://foo.bar.com 
name: My Cool App

is transformed into these properties:

environments.dev.url=http://dev.bar.com 
environments.dev.name=Developer Setup 
environments.prod.url=http://foo.bar.com 
environments.prod.name=My Cool App

Lists are split as property keys with [] dereferencers, for example this YAML:

servers: 
- dev.bar.com 
- foo.bar.com

becomes properties like this:

servers[0]=dev.bar.com 
servers[1]=foo.bar.com

Requires SnakeYAML 1.18 or higher, as of Spring Framework 5.0.6.
[中]java工厂。util。从YAML源读取的属性，公开字符串属性值的平面结构。
YAML是一种很好的人类可读的配置格式，它具有一些有用的层次属性。它或多或少是JSON的超集，所以它有很多类似的特性。
注意：所有公开的值都是字符串类型，可以通过公共属性#getProperty方法进行访问（例如，通过PropertyResourceConfigurator#setProperties（Properties）进行配置属性解析）。如果这不可取，请改用YamlMapFactoryBean。
此工厂创建的属性具有层次对象的嵌套路径，因此，例如，此YAML

environments: 
dev: 
url: http://dev.bar.com 
name: Developer Setup 
prod: 
url: http://foo.bar.com 
name: My Cool App

被转换为以下属性：

environments.dev.url=http://dev.bar.com 
environments.dev.name=Developer Setup 
environments.prod.url=http://foo.bar.com 
environments.prod.name=My Cool App

列表被拆分为带有[]解引用器的属性键，例如，这个YAML:

servers: 
- dev.bar.com 
- foo.bar.com

变成如下属性：

servers[0]=dev.bar.com 
servers[1]=foo.bar.com

从Spring Framework 5.0.6开始，需要SnakeYAML 1.18或更高版本。
