All Implemented Interfaces:

org.springframework.beans.factory.FactoryBean<Map<String,Object>>

public class YamlMapFactoryBean
extends YamlProcessor
implements org.springframework.beans.factory.FactoryBean<Map<String,Object>>

Factory for Map that reads from a YAML source. 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 effecive 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.
