前言

前面有一篇文章介绍了使用selenium获取上市公司半年报的方法，这篇文章就给这些数据写一个简单的前端展示页面

上一篇文章的链接在这里

【java爬虫】使用selenium获取某交易所公司半年报数据-CSDN博客

首先来看一下整个页面的展示效果

前端页面采用vue+element-plus+axio进行编写，采用cdn的方式引入，只有一个index.html文件。

我们要展示的数据如下：

  • 整体的统计数据（各种平均值）
  • 经营收入排名前十的公司
  • 净利润排名前十的公司
  • 经营现金流排名前十的公司
  • 资产收益率排名前十的公司
  • 基本每股收益排名前十的公司
  • 资产负债率排名前十的公司

第一个组数据用<el-descriptions>进行展示，后面的数据用<el-table>进行展示。

后端部分

我们需要写一些sql语句用于统计这些数据。

首先需要写一个用于获取第一组数据的实体类

@Data
@AllArgsConstructor
@NoArgsConstructor
public class StatisticsEntity {

    // 平均营业收入
    private Double incomeavg;

    // 平均净利润
    private Double profit1avg;

    // 平均经营现金流
    private Double cashflowavg;

    // 平均资产收益率
    private Double rate1avg;

    // 平均基本每股收益
    private Double rate2avg;

    // 平均资产负债率
    private Double rate3avg;
}

接着是Mapper接口

@Mapper
public interface ReportMapper {

    // 清空表
    public void clearAll();

    // 插入一条数据
    public void insertOneItem(@Param("item")ReportEntity entity);

    // 查询营业收入最高的十大公司
    public List<ReportEntity> queryMaxIncome();

    // 查询净利润最高的十大公司
    public List<ReportEntity> queryMaxProfit();

    // 查询经营现金流最高的十大公司
    public List<ReportEntity> queryMaxCashflow();

    // 查询净资产收益率最高的十大公司
    public List<ReportEntity> queryMaxRate1();

    // 查询每股收益最高的十大公司
    public List<ReportEntity> queryMaxRate2();

    // 查询资产负债率率最高的十大公司
    public List<ReportEntity> queryMaxRate3();

    // 平均营业收入
    public Double queryIncomeAvg();

    // 平均净利润
    public Double queryProfit1Avg();

    // 平均经营现金流
    public Double queryCashflowAvg();

    // 平均资产负债率
    public Double queryRate1Avg();

    // 平均基本每股收益
    public Double queryRate2Avg();

    // 平均资产负债率
    public Double queryRate3Avg();

}

Mapper对应的xml文件

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper

    <delete id="clearAll">

    </insert>

    <select id="queryMaxIncome" resultType="ReportEntity">
        select
        <include refid="select_columns"></include>
        from t_report
        order by income DESC
        limit 10
    </select>

    <select id="queryMaxProfit" resultType="ReportEntity">
        select
        <include refid="select_columns"></include>
        from t_report

    <select id="queryMaxCashflow" resultType="ReportEntity">

    </select>

    <select id="queryMaxRate1" resultType="ReportEntity">

    <select id="queryMaxRate2" resultType="ReportEntity">

    <select id="queryIncomeAvg" resultType="Double">

    <select id="queryRate2Avg" resultType="Double">
        select

    <select id="queryRate3Avg" resultType="Double">
        select
        avg(rate3)
        from t_report
    </select>

</mapper>

最后是Controller类

@Controller
@CrossOrigin(origins = "*")
public class QueryController {

    @Autowired
    private ReportMapper reportMapper;

    @RequestMapping("queryBaseInfo")
    @ResponseBody
    public String queryBaseInfo() {
        StatisticsEntity statisticsEntity = new StatisticsEntity();
        statisticsEntity.setIncomeavg(reportMapper.queryIncomeAvg());
        statisticsEntity.setCashflowavg(reportMapper.queryCashflowAvg());
        statisticsEntity.setProfit1avg(reportMapper.queryProfit1Avg());
        statisticsEntity.setRate1avg(reportMapper.queryRate1Avg());
        statisticsEntity.setRate2avg(reportMapper.queryRate2Avg());
        statisticsEntity.setRate3avg(reportMapper.queryRate3Avg());
        return JSON.toJSONString(statisticsEntity);
    }


    @RequestMapping("queryMaxIncome")
    @ResponseBody
    public String queryMaxIncome() {
        List<ReportEntity> reportEntities = reportMapper.queryMaxIncome();
        return JSON.toJSONString(reportEntities);
    }

    @RequestMapping("queryMaxProfit")
    @ResponseBody
    public String queryMaxProfit() {
        List<ReportEntity> reportEntities = reportMapper.queryMaxProfit();
        return JSON.toJSONString(reportEntities);
    }

    @RequestMapping("queryMaxCashflow")
    @ResponseBody
    public String queryMaxCashflow() {
        List<ReportEntity> reportEntities = reportMapper.queryMaxCashflow();
        return JSON.toJSONString(reportEntities);
    }

    @RequestMapping("queryMaxRate1")
    @ResponseBody
    public String queryMaxRate1() {
        List<ReportEntity> reportEntities = reportMapper.queryMaxRate1();
        return JSON.toJSONString(reportEntities);
    }

    @RequestMapping("queryMaxRate2")
    @ResponseBody
    public String queryMaxRate2() {
        List<ReportEntity> reportEntities = reportMapper.queryMaxRate2();
        return JSON.toJSONString(reportEntities);
    }

    @RequestMapping("queryMaxRate3")
    @ResponseBody
    public String queryMaxRate3() {
        List<ReportEntity> reportEntities = reportMapper.queryMaxRate3();
        return JSON.toJSONString(reportEntities);
    }
}
