文章目录1.全局设置标题和内容字体格式2.个性化设置某一列格式3.无内容时 预制模板流形式写会1.全局设置标题和内容字体格式
通过WriteCellStyle 的dataFormat属性和BuiltinFormats指定字体格式 这种单元格有内容时字体才会生效无内容时还是常规格式 private static WriteHandler templateWriteHandler;static {//表头样式WriteCellStyle headWriteCellStyle new WriteCellStyle();//字体WriteFont headWriteFont new WriteFont();headWriteFont.setFontHeightInPoints((short) 11);headWriteFont.setBold(true);headWriteCellStyle.setWriteFont(headWriteFont);//边框headWriteCellStyle.setBorderBottom(BorderStyle.THIN);headWriteCellStyle.setBorderLeft(BorderStyle.THIN);headWriteCellStyle.setBorderRight(BorderStyle.THIN);//前景色headWriteCellStyle.setFillForegroundColor(IndexedColors.WHITE.getIndex());//是否换行headWriteCellStyle.setWrapped(true);headWriteCellStyle.setLocked(true);//表体样式WriteCellStyle bodyWriteCellStyle new WriteCellStyle();//设置数据格式索引bodyWriteCellStyle.setDataFormat((short)49);templateWriteHandler new HorizontalCellStyleStrategy(headWriteCellStyle,bodyWriteCellStyle);}//快速根据索引获取字符串、或根据字符串获取索引public static void main(String[] args) {int builtinFormat BuiltinFormats.getBuiltinFormat(h:mm:ss AM/PM);System.out.println(builtinFormat);String builtinFormat1 BuiltinFormats.getBuiltinFormat(49);System.out.println(builtinFormat1);}记得注册 excelWriterBuilder.registerWriteHandler(templateWriteHandler);2.个性化设置某一列格式
继承 AbstractVerticalCellStyleStrategy 实现个性化方法 单独设置某一列
package com.example.easyexceldemo.bo;import com.alibaba.excel.metadata.Head;
import com.alibaba.excel.write.metadata.style.WriteCellStyle;
import com.alibaba.excel.write.metadata.style.WriteFont;
import com.alibaba.excel.write.style.AbstractVerticalCellStyleStrategy;
import org.apache.poi.ss.usermodel.BorderStyle;
import org.apache.poi.ss.usermodel.IndexedColors;public class DemoVerticalCellStyleStrategy extends AbstractVerticalCellStyleStrategy {Overrideprotected WriteCellStyle headCellStyle(Head head) {WriteCellStyle headWriteCellStyle new WriteCellStyle();//字体WriteFont headWriteFont new WriteFont();headWriteFont.setFontHeightInPoints((short) 11);headWriteFont.setBold(true);headWriteCellStyle.setWriteFont(headWriteFont);//边框headWriteCellStyle.setBorderBottom(BorderStyle.THIN);headWriteCellStyle.setBorderLeft(BorderStyle.THIN);headWriteCellStyle.setBorderRight(BorderStyle.THIN);//前景色headWriteCellStyle.setFillForegroundColor(IndexedColors.WHITE.getIndex());//是否换行headWriteCellStyle.setWrapped(true);headWriteCellStyle.setLocked(true);return headWriteCellStyle;}Overrideprotected WriteCellStyle contentCellStyle(Head head) {Integer columnIndex head.getColumnIndex();//这里只单独设置第4列看情况自己修改DateFormat取值见 demo1 的 BuiltinFormats 类if(3 columnIndex){WriteCellStyle bodyWriteCellStyle new WriteCellStyle();//设置数据格式索引bodyWriteCellStyle.setDataFormat((short)49);return bodyWriteCellStyle;}else {return new WriteCellStyle();}}
}
记得注册 excelWriterBuilder.registerWriteHandler(templateWriteHandler);3.无内容时 预制模板流形式写会
其实我遇到的场景就只是简单的空白模板网上找了好多为无内容excel设置文本格式的资料都没有解决。后来干脆把模板上传到resource。 GetMapping(/invoiceTemplateDownload2)public void templateDownload2(HttpServletResponse response) throws IOException {response.setContentType(application/vnd.ms-excel);response.setCharacterEncoding(utf-8);String fileName URLEncoder.encode(模板, UTF-8).replaceAll(\\, %20);response.setHeader(Content-disposition, attachment;filename*utf-8 fileName .xlsx);byte[] fileToByteArray FileUtils.readFileToByteArray(new File(src/main/resources/invoiceTemplate.xlsx));response.getOutputStream().write(fileToByteArray);}
