Examples of org.springframework.core.env.ConfigurableEnvironment.merge()

org.springframework.core.env.ConfigurableEnvironment.merge()

Append the given parent environment's active profiles, default profiles and property sources to this (child) environment's respective collections of each.

For any identically-named {@code PropertySource} instance existing in bothparent and child, the child instance is to be preserved and the parent instance discarded. This has the effect of allowing overriding of property sources by the child as well as avoiding redundant searches through common property source types, e.g. system environment and system properties.

Active and default profile names are also filtered for duplicates, to avoid confusion and redundant storage.

The parent environment remains unmodified in any case. Note that any changes to the parent environment occurring after the call to {@code merge} will not bereflected in the child. Therefore, care should be taken to configure parent property sources and profile information prior to calling {@code merge}. @param parent the environment to merge with @since 3.1.2 @see org.springframework.context.support.AbstractApplicationContext#setParent
