Motivation
When more than one
CorsConfigurationSourcebean is present in the application context,Spring Security fails to start with an ambiguous bean definition error.
From a user’s perspective, this is confusing because a custom
CorsConfigurationSourcebean may already be defined, yet Spring Securitydoes not indicate which one it expects to use.
The current CORS section of the reference documentation does not describe
what happens when multiple
CorsConfigurationSourcebeans are present.Changes in this PR
This PR updates the CORS section of the Spring Security reference documentation to:
CorsConfigurationSourcewhen multiple candidates are available.@Qualifier,@Primary, or the.cors()DSL.Related Issue
