类名称：YamlMapFactoryBean

YamlMapFactoryBean介绍

[英]Factory for a Map that reads from a YAML source, preserving the YAML-declared value types and their structure.

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.

If multiple resources are provided the later ones will override entries in the earlier ones hierarchically; that is, all entries with the same nested key of type Map at any depth are merged. For example:

foo: 
bar: 
one: two 
three: four

plus (later in the list)

foo: 
bar: 
one: 2 
five: six

results in an effective input of

foo: 
bar: 
one: 2 
three: four 
five: six

Note that the value of "foo" in the first document is not simply replaced with the value in the second, but its nested values are merged.
[中]从YAML源读取的映射的工厂，保留YAML声明的值类型及其结构。
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。
如果提供了多个资源，后面的资源将在层次上覆盖前面资源中的条目；也就是说，所有在任何深度具有相同嵌套键的Map类型的条目都会合并。例如：

foo: 
bar: 
one: two 
three: four

plus（列表后面）

foo: 
bar: 
one: 2 
five: six

将有效输入

foo: 
bar: 
one: 2 
three: four 
five: six

请注意，第一个文档中的“foo”值不是简单地替换为第二个文档中的值，而是将其嵌套值合并。
