EasyExcel设置表头上面的那种大标题（前端传递来的大标题）

1、首先得先引用easyExcel的版本依赖，我那

java 复制代码

<dependency>
   <groupId>com.alibaba</groupId>
   <artifactId>easyexcel</artifactId>
   <version>2.2.6</version>
</dependency>

2、然后得弄直接的实体类，（这个实体类是关键，主要的功能就是为了导出的表头还有大标题做准备）

解释： @ExcelProperty(value ={"${bigHead}","区划名称"},index = 0)

这个主要 ${bigHead} 这个是大标题，这个标题是动态生成的，

    }

    public String getXiangzhenwaixianneiwug() 
    {
        return xiangzhenwaixianneiwug;
    }
    public void setTpguowaiwug(String tpguowaiwug) 
    {
        this.tpguowaiwug = tpguowaiwug;

    }

    public String getYqxiangzhenwaixianneiwug() 
    {
        return yqxiangzhenwaixianneiwug;
    }

}

3、然后定义一个接口接收的DTO类

java 复制代码

package com.inspur.grp.hrss.labour.project.labourReport.dto;

import com.inspur.grp.hrss.labour.project.labourReport.LabourDayUpdatetime;

import java.util.List;

public class ExportDataRequestDto {
    private List<LabourDayUpdatetime> labourDayUpdatetimeList;
    private String addressName; // 这个是前端传递的过了的标题名称

    // Getters and Setters
    public List<LabourDayUpdatetime> getLabourDayUpdatetimeList() {
        return labourDayUpdatetimeList;
    }

    public void setLabourDayUpdatetimeList(List<LabourDayUpdatetime> labourDayUpdatetimeList) {
        this.labourDayUpdatetimeList = labourDayUpdatetimeList;
    }

    public String getAddressName() {
        return addressName;
    }

    public void setAddressName(String addressName) {
        this.addressName = addressName;
    }
}

4、封装标题工具类

java 复制代码

package com.inspur.grp.hrss.labour.util.IDCardUtils;

import cn.hutool.core.collection.CollectionUtil;
import cn.hutool.core.util.ObjectUtil;
import com.alibaba.excel.metadata.CellData;
import com.alibaba.excel.metadata.Head;
import com.alibaba.excel.write.handler.CellWriteHandler;
import com.alibaba.excel.write.metadata.holder.WriteSheetHolder;
import com.alibaba.excel.write.metadata.holder.WriteTableHolder;
import org.apache.poi.ss.usermodel.Cell;
import org.apache.poi.ss.usermodel.Row;
import org.springframework.util.PropertyPlaceholderHelper;

import java.util.List;
import java.util.Properties;

public class ExcelTitleHandler implements CellWriteHandler {
    /**
     错误信息处理时正则表达式的格式
     */
    private final String EXCEL_ERROR_REG = "^(.*)(\\(错误:)(.*)(\\))$";

    private String bigHead;


    PropertyPlaceholderHelper placeholderHelper = new PropertyPlaceholderHelper("${", "}");

    public ExcelTitleHandler( String bigHead) {
        this.bigHead = bigHead; //表头1
    }

    @Override
    public void beforeCellCreate(WriteSheetHolder writeSheetHolder, WriteTableHolder writeTableHolder, Row row, Head head, Integer columnIndex, Integer relativeRowIndex, Boolean isHead) {
        // 动态设置表头字段
        if (!ObjectUtil.isEmpty(head)) {
            List<String> headNameList = head.getHeadNameList();
            if (CollectionUtil.isNotEmpty(headNameList)) {
                Properties properties = new Properties();
                properties.setProperty("bigHead", bigHead);
                for (int i = 0 ; i < headNameList.size() ; i++){
                    // 循环遍历替换
                    headNameList.set(i, placeholderHelper.replacePlaceholders(headNameList.get(i), properties));
                }
            }
        }
    }
    @Override
    public void afterCellCreate(WriteSheetHolder writeSheetHolder, WriteTableHolder writeTableHolder, Cell cell, Head head, Integer relativeRowIndex, Boolean isHead) {
    }

    @Override
    public void afterCellDataConverted(WriteSheetHolder writeSheetHolder, WriteTableHolder writeTableHolder, CellData cellData, Cell cell, Head head, Integer integer, Boolean aBoolean) {

    }

    @Override
    public void afterCellDispose(WriteSheetHolder writeSheetHolder, WriteTableHolder writeTableHolder, List<CellData> list, Cell cell, Head head, Integer integer, Boolean aBoolean) {

    }
}

5、开始接口请求

java 复制代码

   //每日更新统计导出
    @PostMapping("/exportDataUpdate")
    public void exportDataUpdate(@RequestBody ExportDataRequestDto exportDataRequestDto, HttpServletResponse response) {
        labourDayUpdatetimeService.exportDataUpdate(exportDataRequestDto, response);
    }

6、service层

java 复制代码

void exportDataUpdate(ExportDataRequestDto exportDataRequestDto, HttpServletResponse response);

7、serviceImpl实现类

java 复制代码

 private void setIntValueFromDoubleString(LabourDayUpdatetime recode, String value, Consumer<String> setter) {
        if (value != null && !value.isEmpty()) {
            try {
                int intValue = (int) Double.parseDouble(value);
                setter.accept(String.valueOf(intValue));
            } catch (NumberFormatException e) {
                setter.accept("0");
            }
        } else {
            setter.accept("0");
        }
    }
    private void setFormattedPercentage(LabourDayUpdatetime recode, String value, Consumer<String> setter) {
        if (value != null && !value.isEmpty()) {
            try {
                double doubleValue = Double.parseDouble(value);
                String formattedValue = String.format("%.2f%%", doubleValue * 100);
                setter.accept(formattedValue);
            } catch (NumberFormatException e) {
                setter.accept("0.00%");
            }
        } else {
            setter.accept("0.00%");
        }
    }


    @Override
    public void exportDataUpdate(ExportDataRequestDto exportDataRequestDto, HttpServletResponse response) {
        String bigHead=exportDataRequestDto.getAddressName()+"劳动力更新报表";
        List<LabourDayUpdatetime> labourDayUpdatetimeList = exportDataRequestDto.getLabourDayUpdatetimeList();
        labourDayUpdatetimeList.stream().forEach(recode->{

            setIntValueFromDoubleString(recode, recode.getNcldlrs(), recode::setNcldlrs);
            setIntValueFromDoubleString(recode, recode.getGxrsa(), recode::setGxrsa);
            setFormattedPercentage(recode, recode.getGxla(), recode::setGxla);
            setIntValueFromDoubleString(recode, recode.getJyrsa(), recode::setJyrsa);
            setIntValueFromDoubleString(recode, recode.getGuowaiwug(), recode::setGuowaiwug);
            setIntValueFromDoubleString(recode, recode.getShengwai(), recode::setShengwai);
            setIntValueFromDoubleString(recode, recode.getShiwaishengnei(), recode::setShiwaishengnei);

            response.setContentType("application/vnd.ms-excel");
            response.setCharacterEncoding("utf-8");
            response.setHeader("Content-disposition", "attachment;filename=" + "数据" + ".xlsx");

            //设置头部标题居中
            headWriteCellStyle.setHorizontalAlignment(HorizontalAlignment.CENTER);
            // 这个策略是 头是头的样式 内容是内容的样式 其他的策略可以自己实现
            HorizontalCellStyleStrategy horizontalCellStyleStrategy =
                    new HorizontalCellStyleStrategy(headWriteCellStyle, contentWriteCellStyle);

            EasyExcel.write(response.getOutputStream(), LabourDayUpdatetime.class)
                    .sheet("数据")
                    .registerWriteHandler(new ExcelTitleHandler(bigHead))
                    .registerWriteHandler(new SimpleColumnWidthStyleStrategy(20)).registerWriteHandler(horizontalCellStyleStrategy)
                    .doWrite(labourDayUpdatetimeList);
        }catch (Exception e){
            throw new RuntimeException(e);
        }
    }

7、前端vue的接口

具体代码就不列出了，这个 daochu 就是一个按钮button

java 复制代码

daochu(){
            if(this.tableData.length==0){
                this.$message({ message: '请确保有数据进行导出', type: 'warning' });return;
            }else{
                const loading = this.$loading({lock: true,text: '导出中',spinner: 'el-icon-loading',background: ' rgba(255, 255, 255, 0.6)'});
                var data = {
                    labourDayUpdatetimeList: this.tableData, // 这个tableData 这个是你要导出的数据
                    addressName: this.addressName // 这个是你要给你的excel设置的大标题
                }
                //发送接口请求
                labourReportApi.exportDataUpdate(data).then(res => { 

                    const url = window.URL.createObjectURL(new Blob([res]));
                    const link = document.createElement('a');
                    link.href = url;
                    link.setAttribute('download', '每日更新情况调度统计.xlsx');
                    document.body.appendChild(link);
                    link.click();
                    document.body.removeChild(link);
                    window.URL.revokeObjectURL(url);
                    this.$message({message: '导出数据成功', type: 'success' });
                    setTimeout(() => {loading.close();}, 1000);
                })
            }
        },

8、具体vue请求

这个是一个js，你可以赋值到你自己的接口js里面去

java 复制代码

import request from "@/util/request";
var prefixD = customConfig.VUE_APP_CLIENT_ID + "/labourReport/updatetimeDayTj";
export default {

  //每日更新导出
  exportDataUpdate: async function (params) {
    return request
    ({
      url: prefixD + "/exportDataUpdate",
      method: "post",
      data: params,
      responseType: "arraybuffer",
      headers: {
        'Content-Type': 'application/json'
      }
    })
  },


}

9、导出已经完成了，展示效果

因为数据量很多，就展示部分
