java - spring.config.import 和 @ConfigurationProperties

Question

我正在尝试从 Spring Boot 2.4 应用程序中的 application.properties 加载一个数组，其中该数组分布在多个属性文件中。

1. 应用程序属性

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 Bean

    @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;
    }

    

在启动应用程序时，我遇到以下错误 -

Action:

Update your application's configuration

有什么方法可以使这项工作无需在 java 注释中明确提及 one.properties 文件（以及除 application.properties 文件之外的任何其他附加文件）吗？
