基于Morphia实现MongoDB按小时、按天聚合操作方法

@Data
@Builder
@Entity(value = "rawDevStatus", noClassnameStored = true)
// 设备状态索引
@Indexes({
    // 设置数据超时时间(TTL，MongoDB根据TTL在后台进行数据删除操作)
    @Index(fields = @Field("time"), options = @IndexOptions(expireAfterSeconds = 3600 * 24 * 72)),
    @Index(fields = {@Field("userId"), @Field(value = "time", type = IndexType.DESC)})
})
public class RawDevStatus {
  @Id
  @JsonProperty(access = JsonProperty.Access.WRITE_ONLY)
  private ObjectId objectId;
  private String userId;
  private Instant time;
  @Embedded("points")
  List<Point> protocolPoints;
  @Data
  @AllArgsConstructor
  public static class Point {
    
    private Protocol protocol;
    
    private Integer total;
    
    private Integer onlineNum;
    
    private Integer enableNum;
  }
}
