spring.config.import and @ConfigurationProperties

Question

I am trying to load an array from application.properties in a Spring boot 2.4 application whereby the array is distributed across multiple property files.

1. application.properties

spring.cloud.routes[0].id=1
spring.cloud.routes[0].name=ONE
spring.cloud.routes[1].id=2
spring.cloud.routes[1].name=TWO
spring.config.import=one.properties

2. one.properties

spring.cloud.routes[2].id=3
spring.cloud.routes[2].name=THREE
spring.cloud.routes[3].id=4
spring.cloud.routes[3].name=FOUR

3. Java Beans

    @Getter
    @Setter
    public class Route {
        private String id;
        private String name;
    }
    
    @Getter
    @Setter
    @ConfigurationProperties(prefix = "spring.cloud")
    @Component
    public class Routes {
        private List<Route> routes;
    }

    

On starting application, I am getting below error -

Action:

Update your application's configuration

Is there any way to make this work without having to explicitly mention one.properties file (and any other additional files besides application.properties file) in java annotations?
