最近公司項目做了一個功能模塊里面有個需求，是要求做一個時間篩選的操作，包括今天，昨天，本周，近七天，半月，上月，自定義這個選項,剛剛開始寫的代碼比較low逼，都是寫在控制器controller里面，具體代碼如下:

if("0".equals(searchDate)){//今天
bookingManageList =bookingManageService.getBoookingManageList(status,todayStart,todayEnd, null, keyWord, pageNum, pageSize,storeId,drawer);
totalAmount = bookingManageService.getTotalAmount(status,storeId,todayStart,todayEnd,null,keyWord,drawer);//獲取總計金額
count =bookingManageService.getCount(status,todayStart,todayEnd, null, keyWord, pageNum, pageSize,storeId,drawer);
}
if("1".equals(searchDate)){//昨天
bookingManageList =bookingManageService.getBoookingManageList(status, yesterdayStart,yesterdayEnd,null,keyWord, pageNum, pageSize,storeId,drawer);
totalAmount = bookingManageService.getTotalAmount(status,storeId,yesterdayStart,yesterdayEnd,null,keyWord,drawer);//獲取總計金額
count =bookingManageService.getCount(status, yesterdayStart,yesterdayEnd,null,keyWord, pageNum, pageSize,storeId,drawer);
}
if("2".equals(searchDate)){//本周
bookingManageList =bookingManageService.getBoookingManageList(status, startTimeWeek, endTimeWeek, null, keyWord, pageNum, pageSize,storeId,drawer);
totalAmount = bookingManageService.getTotalAmount(status,storeId,startTimeWeek,endTimeWeek,null,keyWord,drawer);//獲取總計金額
count =bookingManageService.getCount(status, startTimeWeek, endTimeWeek, null, keyWord, pageNum, pageSize,storeId,drawer);
}
if("3".equals(searchDate)){//近7天
bookingManageList =bookingManageService.getBoookingManageList(status, DateUtil.formatDate(recentSevenDay,"yyyy-MM-dd")+" 00:00:00",yesterdayEnd, null, keyWord, pageNum, pageSize,storeId,drawer);
totalAmount = bookingManageService.getTotalAmount(status,storeId,DateUtil.formatDate(recentSevenDay,"yyyy-MM-dd")+" 00:00:00",yesterdayEnd,null,keyWord,drawer);//獲取總計金額
count =bookingManageService.getCount(status, DateUtil.formatDate(recentSevenDay,"yyyy-MM-dd")+" 00:00:00",yesterdayEnd, null, keyWord, pageNum, pageSize,storeId,drawer);
}
if("4".equals(searchDate)){//本月
bookingManageList =bookingManageService.getBoookingManageList(status, startTimeMonth, endTimeMonth, null,keyWord, pageNum, pageSize,storeId,drawer);
totalAmount = bookingManageService.getTotalAmount(status,storeId,startTimeMonth,endTimeMonth,null,keyWord,drawer);//獲取總計金額
count =bookingManageService.getCount(status, startTimeMonth, endTimeMonth, null,keyWord, pageNum, pageSize,storeId,drawer);
}
if("5".equals(searchDate)){//上月
bookingManageList =bookingManageService.getBoookingManageList(status,lastMonthStartTime,lastMonthEndTime, null, keyWord, pageNum, pageSize,storeId,drawer);
totalAmount = bookingManageService.getTotalAmount(status,storeId,lastMonthStartTime,lastMonthEndTime,null,keyWord,drawer);//獲取總計金額
count =bookingManageService.getCount(status,lastMonthStartTime,lastMonthEndTime, null, keyWord, pageNum, pageSize,storeId,drawer);
}
if("6".equals(searchDate)){//自定義
bookingManageList =bookingManageService.getBoookingManageList(status,startDate,endDate, null, keyWord, pageNum, pageSize,storeId,drawer);
totalAmount = bookingManageService.getTotalAmount(status,storeId,startDate,endDate,null,keyWord,drawer);//獲取總計金額
count =bookingManageService.getCount(status,startDate,endDate, null, keyWord, pageNum, pageSize,storeId,drawer);
}

后來優化封裝了一下，立刻代碼就變簡潔了不少:

public Map<String,String> getDateByStr(String str,String startDate,String endDate){

Map<String,String> map = new Map<String,String>

if("3".equals(str)){
map.put("beginTime", DateUtil.getAnyDate(-7));
map.put("endTime", DateUtil.getAnyDate(0));
}else if("0".equals(str)){
map.put("beginTime", DateUtil.getAnyDate(0));
map.put("endTime", DateUtil.getAnyDate(0));
}else if("1".equals(str)){
map.put("beginTime", DateUtil.getAnyDate(-1));
map.put("endTime", DateUtil.getAnyDate(-1));
}else if("2".equals(str)){
map.put("beginTime", DateUtil.getThisWeekStartAndEnd().get("startTime"));
map.put("endTime", DateUtil.getAnyDate(0));
}else if("4".equals(str)){
map.put("beginTime", DateUtil.getThisMonthStartAndEndDay().get("startTime"));
map.put("endTime", DateUtil.getThisMonthStartAndEndDay().get("endTime"));
}else if("5".equals(str)){
map.put("beginTime", DateUtil.getLastWeekStartAndEnd().get("startTime"));
map.put("endTime", DateUtil.getLastWeekStartAndEnd().get("endTime"));
}else{
map.put("beginTime", startDate);
map.put("endTime", endTime);
}
return map;

}

}

總結:在真正開發過程之中，可能寫的比較趕就沒有仔細思考怎么寫比較好，做事情還是不能急，要先構思好再寫，沒有想清楚堅決不要動手開始做，做也是白做，做開發，不是在工地上面搬磚，瞎搞就行，一個好的思路，往往就成功了一半，每個做開發的都要有這個覺悟
