mongo 操作数据库的方式

 

1. jpa

eg1

public interface CouponInfoRepository extends MongoRepository<CouponInfo, String>{

    /**
     * 跟进优惠券类型ID查找卷码
     * @param couponId 优惠券类型ID
     * @return 列表
     */
    List<CouponInfo> findByCouponId(String couponId);
}

List<CouponInfo> couponInfos = couponInfoRepository.findByCouponId(couponId);

2.spting data MongoTemplate

eg1:

Criteria criteria = new Criteria();
criteria.and("couponState").is(EnumCouponState.PUBLISH);
TypedAggregation typedAggregation = TypedAggregation.newAggregation(Coupon.class, Arrays.asList(
        TypedAggregation.match(criteria),
        TypedAggregation.group("brandName")));
AggregationResults<Map> aggregationResults = mongoTemplate.aggregate(typedAggregation, Map.class);

eg2:

Original original = mongoTemplate.findById("600fe698fececf417c47acea", Original.class);

@Getter
@Setter
@ToString(callSuper = true)
@Document(collection = "original")
@EqualsAndHashCode(callSuper = true)
@CompoundIndexes({
    @CompoundIndex(name = "tenantId_1_updateTime_1", def = "{'tenantId':1, 'updateTime':1}", background = true),
    @CompoundIndex(name = "tenantId_1_originalId_1", def = "{'tenantId':1, 'originalId':1}", unique = true, background = true)
})
public class Original extends BaseClue {

    /** 活动ID */
    private String activityId;

    /** 原始线索业务ID */
    private String originalId;

    /** 归集结果 */
    private GroupResultEnum groupResult;

    /** 扩展标记 */
    private String mark;

    /** 询底价：试驾时间 */
    private Date driveTime;
}
