@ConfigurationProperties(prefix = "hlkj")
public class ResourcePoolUrlProperties {


    private ResourceNewPowerUrl newPowerSys;

    @Data
    
 
public static class ResourceNewPowerUrl {
        private String username;
        private String password;
        private String distributedRealtimeUrl;
        private String distribsunStationUrl;
        private String centerRealtimeUrl;
        private String distributedPredictUrl;
        private
 
 String stationUser;

        private String stationUrl;
        private String lineUrl;
    }


}

子類

@Data
@Configuration
@EnableConfigurationProperties
@ConfigurationProperties(prefix = "hlkj")
public class ResourcePoolUrlProperties {


    private ResourceNewPowerUrl newPowerSys;

    @Data
    
 
public static class ResourceNewPowerUrl {
        private String username;
        private String password;
        private String distributedRealtimeUrl;
        private String distribsunStationUrl;
        private String centerRealtimeUrl;
        private String distributedPredictUrl;
        private String stationUser;
        private String loginUrl;
        private String stationUrl;
        private String lineUrl;
    }


}

使用:

通過been注入 

@Resource
    ResourcePoolUrlProperties properties;

ResourcePoolUrlProperties.ResourceNewPowerUrl newPowerSys = properties.getNewPowerSys();

String url = newPowerSys.getDistribsunStationUrl();
