营业额统计
- 在admin文件夹下创建ReportController类，并且添加营业额统计方法
- ReportController.java
package com.sky.controller.admin;
import com.sky.result.Result;
import com.sky.service.ReportService;
import com.sky.vo.TurnoverReportVO;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.format.annotation.DateTimeFormat;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import java.time.LocalDate;
@RestController
@RequestMapping("/admin/report")
@Api(tags = "数据统计相关接口")
@Slf4j
public class ReportController {
@Autowired
private ReportService reportService;
@GetMapping("/turnoverStatistics")
@ApiOperation("营业额统计")
public Result<TurnoverReportVO> turnoverStatistics(
@DateTimeFormat(pattern = "yyyy-MM-dd") LocalDate begin,
@DateTimeFormat(pattern = "yyyy-MM-dd") LocalDate end){
log.info("营业额统计:{},{}",begin,end);
TurnoverReportVO turnoverStatistics = reportService.getTurnoverStatistics(begin, end);
return Result.success(turnoverStatistics);
}
}
- 同理创建ReportService类，添加相应接口，并且在实现类中实现
- ReportServiceImpl.java
package com.sky.service.impl;
import com.sky.entity.Orders;
import com.sky.mapper.OrderMapper;
import com.sky.service.ReportService;
import com.sky.vo.TurnoverReportVO;
import lombok.extern.slf4j.Slf4j;
import org.apache.commons.lang3.StringUtils;
import org.apache.poi.util.StringUtil;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import java.time.LocalDate;
import java.time.LocalDateTime;
import java.time.LocalTime;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
@Service
@Slf4j
public class ReportServiceImpl implements ReportService {
@Autowired
private OrderMapper orderMapper;
@Override
public TurnoverReportVO getTurnoverStatistics(LocalDate begin, LocalDate end) {
List<LocalDate> dateList = new ArrayList<>();
dateList.add(begin);
while (!begin.equals(end)){
begin = begin.plusDays(1);
dateList.add(begin);
}
List<Double> turnoverList = new ArrayList<>();
for (LocalDate date : dateList) {
LocalDateTime beginTime = LocalDateTime.of(date, LocalTime.MIN);
LocalDateTime endTime = LocalDateTime.of(date, LocalTime.MAX);
Map map = new HashMap<>();
map.put("begin",beginTime);
map.put("end",endTime);
map.put("status", Orders.COMPLETED);
Double turnover = orderMapper.sumByMap(map);
turnover = turnover == null ? 0.0 : turnover;
turnoverList.add(turnover);
}
return TurnoverReportVO
.builder()
.turnoverList(StringUtils.join(turnoverList,","))
.dateList(StringUtils.join(dateList,","))
.build();
}
}
- mapper层添加相应方法
- OrderMapper.xml
<select id="sumByMap" resultType="java.lang.Double">
select sum(amount) from orders
<where>
<if test="begin != null">
and order_time > #{begin}
</if>
<if test="end != null">
and order_time < #{end}
</if>
<if test="status != null">
and status = #{status}
</if>
</where>
</select>
用户统计
- 在ReportController类添加用户统计方法
- ReportController.java
@GetMapping("/userStatistics")
@ApiOperation("用户统计")
public Result<UserReportVO> userStatistics(
@DateTimeFormat(pattern = "yyyy-MM-dd") LocalDate begin,
@DateTimeFormat(pattern = "yyyy-MM-dd") LocalDate end){
log.info("用户统计:{},{}",begin,end);
return Result.success(reportService.getUserStatistics(begin,end));
}
- 在ReportService类，添加相应接口，并且在实现类中实现
- ReportServiceImpl.java
@Override
public UserReportVO getUserStatistics(LocalDate begin, LocalDate end) {
List<LocalDate> dateList = new ArrayList<>();
dateList.add(begin);
while (!begin.equals(end)){
begin = begin.plusDays(1);
dateList.add(begin);
}
List<Integer> newUserList = new ArrayList<>();
List<Integer> totalUserList = new ArrayList<>();
for (LocalDate date : dateList) {
LocalDateTime beginTime = LocalDateTime.of(date, LocalTime.MIN);
LocalDateTime endTime = LocalDateTime.of(date, LocalTime.MAX);
Map map = new HashMap<>();
map.put("end",endTime);
Integer totalcount = userMapper.countByMap(map);
map.put("begin",beginTime);
Integer newcount = userMapper.countByMap(map);
newUserList.add(newcount);
totalUserList.add(totalcount);
}
return UserReportVO
.builder()
.dateList(StringUtils.join(dateList,","))
.totalUserList(StringUtils.join(totalUserList,","))
.newUserList(StringUtils.join(newUserList,","))
.build();
}
- mapper层添加相应方法
- UserrMapper.xml
<select id="countByMap" resultType="java.lang.Integer">
select count(id) from user
<where>
<if test="begin != null">
and create_time > #{begin}
</if>
<if test="end != null">
and create_time < #{end}
</if>
</where>
</select>
订单统计
- 在ReportController类添加订单统计方法
- ReportController.java
@GetMapping("/ordersStatistics")
@ApiOperation("订单统计")
public Result<OrderReportVO> ordersStatistics(
@DateTimeFormat(pattern = "yyyy-MM-dd") LocalDate begin,
@DateTimeFormat(pattern = "yyyy-MM-dd") LocalDate end){
log.info("订单统计:{},{}",begin,end);
return Result.success(reportService.getOrdersStatistics(begin,end));
}
- 在ReportService类，添加相应接口，并且在实现类中实现

}
List<Integer> orderCountList = new ArrayList<>();
List<Integer> validOrderCountList = new ArrayList<>();
for (LocalDate date : dateList) {
LocalDateTime beginTime = LocalDateTime.of(date, LocalTime.MIN);
LocalDateTime endTime = LocalDateTime.of(date, LocalTime.MAX);
Integer orderCount = getOrderCount(beginTime, endTime, null);
Integer validOrderCount = getOrderCount(beginTime, endTime, Orders.COMPLETED);
orderCountList.add(orderCount);
validOrderCountList.add(validOrderCount);
}
Integer allordercount = orderCountList.stream().reduce(Integer::sum).get();
Integer allvalidordercount = validOrderCountList.stream().reduce(Integer::sum).get();
Double complete = 0.0;
if (allordercount != 0){
complete = allvalidordercount.doubleValue()/allordercount.doubleValue();
}
return OrderReportVO
.builder()
.dateList(StringUtils.join(dateList,","))
.orderCountList(StringUtils.join(orderCountList,","))
.validOrderCountList(StringUtils.join(validOrderCountList,","))
.totalOrderCount(allordercount)
.validOrderCount(allvalidordercount)
.orderCompletionRate(complete)
.build();
}
private Integer getOrderCount(LocalDateTime begin, LocalDateTime end, Integer status){
Map map = new HashMap<>();
map.put("end",end);
map.put("begin",begin);
map.put("status",status);
return orderMapper.countByMap(map);
}
- mapper层添加相应方法

<select id="countByMap" resultType="java.lang.Integer">
select count(id) from orders
<where>
<if test="begin != null">

and order_time < #{end}
</if>
<if test="status != null">

</if>
</where>
</select>
销量统计
- 在ReportController类添加销量统计方法
- ReportController.java
@GetMapping("/top10")
@ApiOperation("销量统计")
public Result<SalesTop10ReportVO> top10(
@DateTimeFormat(pattern = "yyyy-MM-dd") LocalDate begin,
@DateTimeFormat(pattern = "yyyy-MM-dd") LocalDate end){
log.info("销量统计:{},{}",begin,end);
return Result.success(reportService.getSalesTop10(begin,end));
}
- 在ReportService类，添加相应接口，并且在实现类中实现

List<GoodsSalesDTO> goodsSalesDTOList = orderMapper.top10(beginTime, endTime);
List<String> names = goodsSalesDTOList.stream().map(GoodsSalesDTO::getName).collect(Collectors.toList());
String nameList = StringUtils.join(names, ",");
List<Integer> numbers = goodsSalesDTOList.stream().map(GoodsSalesDTO::getNumber).collect(Collectors.toList());
String numberList = StringUtils.join(numbers, ",");
return SalesTop10ReportVO
.builder()
.nameList(nameList)
.numberList(numberList)
.build();
}
- mapper层添加相应方法
- OrderMapper.xml
<select id="top10" resultType="com.sky.dto.GoodsSalesDTO">
select od.name,sum(od.number) number
