yaml 的嵌套配置 - spring boot

Question

下面是我的 yaml 配置。

configuration:
  internalUser:
    add:
      city:            
        path: path
        name: cityName

      country:            
        path: path
        name: countryName
                  
    replace:
      city:                       
        path: path
        name: cityName
    remove:
      city:                       
        path: path
        name: cityName
  externalUser:
    add:
      city:            
        path: path
        name: cityName

      country:            
        path: path
        name: countryName
                  
    replace:
      city:                       
        path: path
        name: cityName
    remove:
      city:                       
        path: path
        name: cityName

    

配置類看起來像：

@ConfigurationProperties(prefix = "configuration")
public class Configuration {

    private Map<String, Map<String,Map<String>,Address>>> internalUser = new HashMap<>();
     //setter and getter
}

Public class Address{
       private String path;
       private String name;
       //setter and getter
    }

加載應用程序時它失敗並且無法投射對象。

我的配置有問題嗎？ 或者我們可以對這個配置使用嵌套配置嗎？ 請幫我配置。

你的地圖太多了。 你只需要兩張地圖。

第一個映射鍵： add, replace, remove

第二個地圖鍵： city

@ConfigurationProperties(prefix = "configuration")
public class Configuration {

    private Map<String, Map<String, Address>>> internalUser;
    private Map<String, Map<String, Address>>> externalUser;
     //setter and getter
}
