Override property in YAML

I have a third party library, that is being configured with the important-config.yaml file.

prop1: value1
prop2: value2(need to override)
prop3: value3

To refer to it I have the next line in application.properties:

important-config=classpath:important-config.yaml

There is a property in yaml-file that depends on environment where app is running. So I need to override this property on startup. How can I do that?

I can see three suitable variants to solve it:

  1. Override properties directly in application.properties. I think that priority of is is higher that included congig (at least you could try to override property after you place important-config).
  2. You can override selected properties using command line directly java -jar app.jar --prop2="value2"
  3. Or override via system properties java -Dprop2="value2"-jar app.jar

Full informaiton you can find here http://www.baeldung.com/properties-with-spring

Absolute all properties are stored in Spring Environment object. You should pay attention on full variable name, because depending on other setting your prop2 could be store in xxx.yyy.prop2.
