public class StandardEnvironment extends AbstractEnvironment
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.
