Prior to this commit, specifying a named @PropertySource with multiple
values would not work as expected. e.g.:
@PropertySource(
name = "ps",
value = { "classpath:a.properties", "classpath:b.properties" })
In this scenario, the implementation would register a.properties with
the name "ps", and subsequently register b.properties with the name
"ps", overwriting the entry for a.properties.
To fix this behavior, a CompositePropertySource type has been introduced
which accepts a single name and a set of PropertySource objects to
iterate over. ConfigurationClassParser's @PropertySource parsing routine
has been updated to use this composite approach when necessary, i.e.
when both an explicit name and more than one location have been
specified.
Note that if no explicit name is specified, the generated property
source names are enough to distinguish the instances and avoid
overwriting each other; this is why the composite wrapper is not used
in these cases.
Issue: SPR-9127
Spring Framework
The Spring Framework provides a comprehensive programming and configuration model for modern Java-based enterprise applications - on any kind of deployment platform. A key element of Spring is infrastructural support at the application level: Spring focuses on the "plumbing" of enterprise applications so that teams can focus on application-level business logic, without unnecessary ties to specific deployment environments.
The framework also serves as the foundation for Spring Integration, Spring Batch and the rest of the Spring family of projects. Browse the repositories under the SpringSource organization on GitHub for a full list.
.NET and Python variants are available as well.
