# Spring Cloud Archaius
|
||||
|
||||
#### Basic Config
|
||||
This service has the basic, out-of-the-box Spring Cloud Netflix Archaius configuration.
|
||||
|
||||
#### Extra Configs
|
||||
This service customizes some properties supported by Archaius.
|
||||
|
||||
These properties are set up on the main method, since Archaius uses System properties, but they could be added as command line arguments when launching the app.
|
||||
|
||||
#### Additional Sources
|
||||
In this service we create a new AbstractConfiguration bean, setting up a new Configuration Properties source.
|
||||
|
||||
These properties have precedence over all the other properties in the Archaius Composite Configuration.
