直接已知子类:
PropertiesPropertySource, SystemEnvironmentPropertySource
```
public class MapPropertySource
extends EnumerablePropertySource<Map<String,Object>>
```
PropertySource that reads keys and values from a Map object. The underlying map should not contain any null values in order to comply with getProperty(java.lang.String) and containsProperty(java.lang.String) semantics.
