,PropertySources
public class MutablePropertySources extends Object implements PropertySources
Default implementation of thePropertySources
interface. Allows manipulation of contained property sources and provides a constructor for copying an existingPropertySources
instance.Where precedence is mentioned in methods such as
addFirst(org.springframework.core.env.PropertySource<?>)
andaddLast(org.springframework.core.env.PropertySource<?>)
, this is with regard to the order in which property sources will be searched when resolving a given property with aPropertyResolver
