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
com.alibaba
easyexcel
2.1.4
2.实体类(注解法)

}
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:
