2 个答案:

答案 0 :(得分：0)

您是否手动更新了任何数据，即直接使用mongodb shell？ ID为17的数据行似乎已被污染。

答案 1 :(得分：0)

我知道这是一个老问题，但它最终可以帮助某人。

无论如何，我有一个类似的问题，我解决了它创建我自己的转换器。

public class LongToDateConverter implements Converter<Long, Date> {
    @Override
    public Date convert(Long lng) {
        if(lng!=null)
            return new Date(lng);
        else
            return null;
    }
}

然后我注册为bean。

@Bean
@Override
public CustomConversions customConversions() throws Exception {
    List<Converter<?, ?>> converterList = new ArrayList<Converter<?, ?>>();
    converterList.add(new LongToDateConverter());

    return new CustomConversions(converterList);
  }
