如需客户端指定excel版本,只需要判断后缀名然后在controller中的.excelType(ExcelTypeEnum.XLS)做指定输出内容格式即可

***(注意表格行高列宽统一设置是在实体类的类名注解上,如果需要对表格进行精细的宽高设置需要删除掉这两个注解,可以在拦截器使用row的方法进行设置)

1. ## 引入依赖

2.实体类(注解法)

controller

@postMapping(“pilebodystatisticsmonthexport”)

public WebApiResponse pilebodystatisticsmonthexport (HttpServletResponse response,String month) throws IOException {

List pilebodysList = pilebodycheckService.pilebodystatisticsmonth(sysDepartDto, month);

//设置序号

for (int i = 1;i <= pilebodysList.size();i++){

pilebodysList.get(i-1).setOrderNum(i+"");

}

response.setContentType(“application/vnd.ms-excel”);

response.setCharacterEncoding(“utf-8”);

// 这里URLEncoder.encode可以防止中文乱码 当然和easyexcel没有关系

String fileName = URLEncoder.encode(“存量建筑垃圾堆体治理进度月报表”, “UTF-8”);

response.setHeader(“Content-disposition”, “attachment;filename=” + fileName + “.xls”);

//内容样式策略

WriteCellStyle contentWriteCellStyle = new WriteCellStyle();

EasyExcel.write(response.getOutputStream(), PilebodycheckMonthDto.class)

//设置输出excel版本,不设置默认为xlsx

.excelType(ExcelTypeEnum.XLS).head(PilebodycheckMonthDto.class)

//设置拦截器或自定义样式

.registerWriteHandler(new MonthSheetWriteHandler())

return new WebApiResponse(200, "生成excel文件成功", null);

}

4. 拦截器

package com.jpxx.admin.pilebody.web.api;

import com.alibaba.excel.write.handler.SheetWriteHandler;

import com.alibaba.excel.write.metadata.holder.WriteSheetHolder;

import com.alibaba.excel.write.metadata.holder.WriteWorkbookHolder;

import org.apache.poi.ss.usermodel.*;

import org.apache.poi.ss.util.CellRangeAddress;

public class MonthSheetWriteHandler implements SheetWriteHandler {

@Override

public void beforeSheetCreate(WriteWorkbookHolder writeWorkbookHolder, WriteSheetHolder writeSheetHolder) {

}

@Override

public void afterSheetCreate(WriteWorkbookHolder writeWorkbookHolder, WriteSheetHolder writeSheetHolder) {

Workbook workbook = writeWorkbookHolder.getWorkbook();

Sheet sheet = workbook.getSheetAt(0);

Row row1 = sheet.createRow(0);

row1.setHeight((short) 500);

Cell cell = row1.createCell(0);

//设置单元格内容

cell.setCellValue("附件2");

//设置标题

Row row2 = sheet.createRow(1);

row2.setHeight((short) 800);

Cell cell1 = row2.createCell(0);

cell1.setCellValue("存量建筑垃圾堆体治理进度月报表");

CellStyle cellStyle = workbook.createCellStyle();

cellStyle.setVerticalAlignment(VerticalAlignment.CENTER);

cellStyle.setAlignment(HorizontalAlignment.CENTER);

Font font = workbook.createFont();

font.setBold(true);

font.setFontHeight((short) 400);

cellStyle.setFont(font);

cell1.setCellStyle(cellStyle);

sheet.addMergedRegionUnsafe(new CellRangeAddress(1, 1, 0, 17));

//设置填表日期,填报人,联系方式

Row row3 = sheet.createRow(2);

row3.setHeight((short) 500);

row3.createCell(1).setCellValue("填表日期");

row3.createCell(11).setCellValue("填表人");

row3.createCell(15).setCellValue("联系方式");

}

}

生成表格如下:
