You have to create Arraylists int this YAML configuration which has the name of the attributes. Than your essential able to call your Object by only calling the attribute.

Example:

    YamlConfiguration yaml = new YamlConfiguration();
    HashMap<String, List<String>> nodetypes = new HashMap<>();
    //setter
    for(String key :nodetypes.keySet()) 
        yaml.set("path."+key,  nodetypes.get(key));
        yaml.set("path."+new String("keys"), nodetypes.keySet());



    //getter
    HashMap<String, List<String>> cp = new HashMap<>();

    for(String key:yaml.getStringList("path."+new String("keys")))
        cp.put(key, yaml.getStringList("path."+key));

您可以尝试将@Component放在@ConrigurationProerties之前
