標籤:分組彙總 type text return direction png local 一個 cal
使用spring data mongodb v1.8
需求1、
資料結構如下。說明:改集合記錄的是公司各個系統的訪問情況(localPath表示系統,requestTime 表示請求時間,字串類型,)
需求:選中某一天,然後按照系統和小時進行分組,統計這一天中每個小時各個系統的訪問情況。
業務代碼:
Criteria criteria = new Criteria();criteria.andOperator(Criteria.where("createTime").lt(DateUtil.addDay(sdf.parse(sdf.format(date)), 1)), Criteria.where("createTime").gte(sdf.parse(sdf.format(date))));// 匹配查詢MatchOperation matchOperation = Aggregation.match(criteria);// localPath// 返回參數ProjectionOperation return1 = Aggregation.project("localPath").andExpression("substr(requestTime,11,2)").as("dimension");// 按條件分組GroupOperation go2 = Aggregation.group("dimension", "localPath").count().as("times");// 設定排序SortOperation sortOperation = Aggregation.sort(Sort.Direction.ASC, "localPath", "dimension");// 構建參數Aggregation aggregation = Aggregation.newAggregation(matchOperation, return1, go2, sortOperation);// 分組彙總查詢AggregationResults<SysCountResultVo> aggregate = mongoTemplate.aggregate(aggregation, getCollectionName(date), SysCountResultVo.class);// 擷取結果List<SysCountResultVo> resultVos = aggregate.getMappedResults();
SysCountResultVo類
public class SysCountResultVo { /**次數**/ private int times; /**服務**/ private String localPath; /**維度**/ private String dimension; public int getTimes() {return times; } public void setTimes(int times) {this.times = times; } public String getLocalPath() {return localPath; } public void setLocalPath(String localPath) {this.localPath = localPath; } public String getDimension() {return dimension; } public void setDimension(String dimension) {this.dimension = dimension; } @Override public String toString() {return "SysCountResultVo [times=" + times + ", localPath=" + localPath + ", dimension=" + dimension + "]"; }}
需求二、
資料結構如下。說明:該集合儲存的是投遞資訊(isView 表示的類型,deliveryTime 表示 投遞時間)
需求:
選擇一個時間段,要求按天和投遞類型進行分組統計。
痛點:
mongodb儲存的時間是utc時間,這個時間比本地時間少8個小時,例如 本地時間為:2018.7.18 00:00:00日,mongodb中儲存的是 2018.7.17 t16:00:00z之類的東西。
按天統計的時候,如果集合中存了字元處,可以使用需求1中的方法,使用substr函數進行處理。但是如果像需求2中,沒有儲存字串,怎麼辦?以下是我的思路。
service
Criteria criteria = new Criteria();/**此處設定匹配條件**/// 匹配查詢MatchOperation matchOperation = Aggregation.match(criteria);// 返回參數,對日期進行處理ProjectionOperation return1 = Aggregation.project("isView").andExpression("year(deliveryTime)").as("year").andExpression("month(deliveryTime)").as("month").andExpression("dayOfMonth(deliveryTime)").as("day").andExpression("hour(deliveryTime)").as("hour");// 按條件分組GroupOperation go2 = Aggregation.group("isView", "year", "month", "day", "hour").count().as("times");// 設定排序SortOperation sortOperation = Aggregation.sort(Sort.Direction.ASC, "times");// 構建參數Aggregation aggregation = Aggregation.newAggregation(matchOperation, return1, go2, sortOperation);// 分組彙總查詢AggregationResults<SysCountResultVo> aggregate = mongoTemplate.aggregate(aggregation, "resumeDeliveryRecordVo", SysCountResultVo.class);// 擷取結果List<SysCountResultVo> resultVos = aggregate.getMappedResults();
SysCountResultVo類
public class SysCountResultVo { /**次數**/ private int times; /**服務**/ private String isView; /**年**/ private Integer year; /**月**/ private Integer month; /**日**/ private Integer day; /**小時**/ private Integer hour; /**時間**/ private String time; private String isViewStr; public int getTimes() {return times; } public void setTimes(int times) {this.times = times; } public String getIsView() {return isView; } public void setIsView(String isView) {this.isView = isView; } public Integer getYear() {return year; } public void setYear(Integer year) {this.year = year; } public Integer getMonth() {return month; } public void setMonth(Integer month) {this.month = month; } public Integer getDay() {return day; } public void setDay(Integer day) {this.day = day; } // 此處為重點,如果時>=16,則認為是下一天 public String getTime() {try { if (hour >= 16) {return DateUtil.date2DateStr(DateUtil.addDay(DateUtil.dateStr2Date(this.getYear() + "-" + this.getMonth() + "-" + this.getDay(), DateUtil.PATTERN_DTSHORTLINE), 1), DateUtil.PATTERN_DTSHORTLINE); } return this.getYear() + "-" + this.getMonth() + "-" + this.getDay();} catch (Exception e) { e.printStackTrace();}return null; } public Integer getHour() { return hour; } public void setHour(Integer hour) { this.hour = hour; } public void setTime(String time) {this.time = time; } public String getIsViewStr() {return Integer.valueOf(isView) == 1 ? "未查看" : Integer.valueOf(isView) == 2 ? "待溝通" : Integer.valueOf(isView) == 4 ? "已檢視" : Integer.valueOf(isView) == 6 ? "不合適" : "其他"; } public void setIsViewStr(String isViewStr) {this.isViewStr = isViewStr; } @Override public String toString() {return "time:" + getTime() + ";times:" + getTimes() + ";isView:" + getIsView(); }}
可能說明的不是很清楚,不過可以作為一個參考。我的QQ:1208576787,如有什麼問題,可以加QQ討論下。
mongodb按照時間分組統計
