java.lang.Objectorg.springframework.core.env.AbstractEnvironment
org.springframework.core.env.StandardEnvironment
public class StandardEnvironment
Environment implementation suitable for use in 'standard' (i.e. non-web)
applications.
In addition to the usual functions of a ConfigurableEnvironment such as
property resolution and profile-related operations, this implementation configures two
default property sources, to be searched in the following order:
environment.getProperty("xyz").
This ordering is chosen by default because system properties are per-JVM, while
environment variables may be the same across many JVMs on a given system. Giving
system properties precedence allows for overriding of environment variables on a
per-JVM basis.
These default property sources may be removed, reordered, or replaced; and
additional property sources may be added using the MutablePropertySources
instance available from AbstractEnvironment.getPropertySources(). See
ConfigurableEnvironment Javadoc for usage examples.
See SystemEnvironmentPropertySource Javadoc for details on special handling
of property names in shell environments (e.g. Bash) that disallow period characters in
variable names.
