mysql獲取某段時間內每一天的統計數據

select date(p.create_time) as one_day,sum(a-b) as total,
       p.cashier from pay_order p where p.create_time between date_format('2019-08-12 08:08:08','%Y%m%d') 
       and date_format('2019-08-13 08:08:08','%Y%m%d') group by one_day order by one_day desc;


如果查詢數據庫，使用入參實體類和出參實體類，需要@Filed注解且name與查詢到的名字一致

@Table(name = "查詢報表輸出實體，不掛具體表")
public class ReportOutParam extends BaseEntity {

    @JsonProperty("oneDay")
    @JsonPropertyDescription("日期")
    @Field(name = "one_day")
    private String oneDay;

　　public String getOneDay() {
    　　return oneDay;
　　}

　　public void setOneDay(String oneDay) {
    　　this.oneDay = oneDay;
　　}

}
