Keys of nested map loaded with ConfigurationProperties are prefixed with their respective indexes

With spring boot I'm trying to load configuration using the annotation @ConfigurationProperties("oauth2.discovery").

Everything works fine except the fact that keys of a nested map are not loaded with the configuration file content but instead they are prefixed with their respectiveindexes.

This is the code used to load the configuration :

@ConfigurationProperties("oauth2.discovery")
public class DiscoveryConfigs {

    private Map<String, DiscoveryConfigs.DiscoveryConfig> config;

    public Map<String, DiscoveryConfigs.DiscoveryConfig> getConfig() {
        return this.config;
    }

    public void setConfig(Map<String, DiscoveryConfigs.DiscoveryConfig> discovery) {
        this.config = discovery;
    }

    public static class DiscoveryConfig {
        private String name;
        private Map<String, String> endpoints;

        public String getName() {
            return name;
        }

        public void setName(String name) {
            this.name = name;
        }

        public Map<String, String> getEndpoints() {
            return endpoints;
        }

        public void setEndpoints(Map<String, String> endpoints) {
            this.endpoints = endpoints;
        }
    }
}

This is my application.yml

oauth2:
  discovery:
    config:
      affiliation:
        name: affiliation-service
        endpoints:
          - public: /getPublic
          - forRoleA: /getForRoleA
          - forRoleB: /getForRoleB
      blabla:
        name: ...

And using DiscoveryConfigs to load the application.yml I got the following content:

( debugger view in IntellIj )
endpoints = {LinkedHashMap@10957} size > = 3
"0.public" -> "/getPublic"
"1.forRoleA" -> "/getForRoleA"
"2.forRoleB" -> "/getForRoleB"

Where keys are for example "0.public" instead of "public"

So I'm sure I missed something but I cannot figure what...

Checkout the description to Binding Maps on spring.io. The following should work:

oauth2:
  discovery:
    config:
      affiliation:
        name: affiliation-service
        endpoints:
          public: /getPublic
          forRoleA: /getForRoleA
          forRoleB: /getForRoleB
