That is, if the key "xyz" is present both in the JVM system properties as well as in the set of environment variables for the current process, the value of key "xyz" from system properties will return from a call toConfigurableEnvironment
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 fromAbstractEnvironment.getPropertySources()
. SeeConfigurableEnvironment
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.- 从以下版本开始:
