In this area, you can define your own application properties. These are added to the existing properties in application.yml / application.properties. Each property consists of a key, an optional condition and a value.
The condition - if given - is again a SpEL expression and must be evaluated to Boolean.TRUE for the property to be added. The value itself is also a SpEL expression with the current project available in the context, but a String output is expected.
Manage your custom application properties
If a property is no longer valid because a custom option has been removed or changed, it is still contained in the list of properties and displayed with a warning.
