nacos-spring-project yaml list取不到值？

https://github.com/nacos-group/nacos-spring-project/issues/174#issue-538159586 请问这是用的是哪个项目sample，我用的nacos-spring-project，环境同issue里描述，启动时listv映射就报错了，其他正常能获取到值。 Caused by: org.springframework.beans.NullValueInNestedPathException: Invalid property 'listv[0]' of bean class [com.alibaba.nacos.example.spring.model.Promotion]: Cannot access indexed value of property referenced in indexed property path 'listv[0]': returned null

private Long sku;
private Double price;
private Integer amount;

@NacosProperty(value = "desc")
@JSONField(name = "desc")
private String description;

@NacosIgnore
private Integer sold;

private List<String> listv;


yml：
 sku: 2
 price: 99.9  
 amount: 1001  
 desc: "Hooray! It's snowing! 下雪了！"  
 description: descipt  
 sold: 100  
 listv:  
    - one  
    - two

这个代码完整的看下，整个应该用@NacosConfigurationOnProperties这个注解

这个代码完整的看下，整个应该用@NacosConfigurationOnProperties这个注解

@NacosConfigurationProperties(dataId = "promotion.yml", groupId = "spring-example", autoRefreshed = true, type = ConfigType.YAML)
public class Promotion {

    private Long sku;

    private Double price;

    private Integer amount;

    @NacosProperty(value = "desc")
    @JSONField(name = "desc")
    private String description;

    @NacosIgnore
    private Integer sold;

    private List<String> listv;

    // getter and setter
