如需客戶端指定excel版本,只需要判斷后綴名然后在controller中的.excelType(ExcelTypeEnum.XLS)做指定輸出內(nèi)容格式即可

***(注意表格行高列寬統(tǒng)一設(shè)置是在實(shí)體類的類名注解上,如果需要對(duì)表格進(jìn)行精細(xì)的寬高設(shè)置需要?jiǎng)h除掉這兩個(gè)注解,可以在攔截器使用row的方法進(jìn)行設(shè)置)

}

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

// 這里URLEncoder.encode可以防止中文亂碼 當(dāng)然和easyexcel沒(méi)有關(guān)系

4. 攔截器

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);

//設(shè)置單元格內(nèi)容

cell.setCellValue("附件2");

//設(shè)置標(biāo)題

Row row2 = sheet.createRow(1);

row2.setHeight((short) 800);

Cell cell1 = row2.createCell(0);

cell1.setCellValue("存量建筑垃圾堆體治理進(jìn)度月報(bào)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));

//設(shè)置填表日期,填報(bào)人,聯(lián)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("聯(lián)系方式");

}

}
