class ConfigurationPropertySourcesPropertySource extends PropertySource<Iterable<ConfigurationPropertySource>> |
In Springboot application，ConfigurationPropertySourcesPropertySource is added to the environment and as first element, the ConfigurationPropertySourcesPropertySource acts as a facade over the existing property sources.
When handling @Value annotation, org.springframework.core.env.PropertySourcesPropertyResolver#getProperty will be called.
If the property is found then ConfigurationPropertySourcesPropertySource will return the result. otherwise, PropertySourcesPropertyResolver continues to check all subsequent sources. This is a little inefficient for any source that has already been check via ConfigurationPropertySourcesPropertySource.
