[spring-projects-issues]

Stéphane Nicoll opened SPR-11639 and commented

This is a follow-up issue of #15179 to consider @Priority as an alternative for @Order.

Update the features that @Order handles so that @Priority can be used with the same semantic.

Introduced OrderUtils that gives the order value based on a type declaration (i.e. Class<?> instance). That utility handle @Order and @Priority if present.
