模板可通过HeadFontStyle、HeadStyle、ContentFontStyle、ContentStyle、HeadRowHeight ContentRowHeight等注解设置excel单元格样式 //字体样式及字体大小 HeadFontStyle(fontName 宋体,fontHeightInPoints 11) ContentFontStyle(fontName 宋体,fontHeightInPoints 11) //标题样式 HeadStyle(wrapped BooleanEnum.FALSE, horizontalAlignment HorizontalAlignmentEnum.CENTER, verticalAlignment VerticalAlignmentEnum.CENTER, borderLeft BorderStyleEnum.THIN, borderRight BorderStyleEnum.THIN, borderTop BorderStyleEnum.THIN, borderBottom BorderStyleEnum.THIN, fillForegroundColor 49) //单元格内容样式 ContentStyle(wrapped BooleanEnum.FALSE, horizontalAlignment HorizontalAlignmentEnum.CENTER, verticalAlignment VerticalAlignmentEnum.CENTER, borderLeft BorderStyleEnum.THIN, borderRight BorderStyleEnum.THIN, borderTop BorderStyleEnum.THIN, borderBottom BorderStyleEnum.THIN, fillForegroundColor 9) //标题及数据行高 HeadRowHeight(24) ContentRowHeight(25) public class CertifyOrderDetailsExcel { ColumnWidth(10)
ExcelProperty(value {统计,名称},index 1)
private String name; ContentStyle(wrapped BooleanEnum.TRUE,horizontalAlignment HorizontalAlignmentEnum.CENTER,verticalAlignment VerticalAlignmentEnum.CENTER,borderLeft BorderStyleEnum.THIN,borderRight BorderStyleEnum.THIN,borderTop BorderStyleEnum.THIN,borderBottom BorderStyleEnum.THIN,fillForegroundColor 9) 使用easyexcelFactory将数据到出excel文件业务实现导出核心部分代码如下//此处list为需要导出的数据通过数据库查询ListObject list null;
// ServletOutputStream outputStream response.getOutputStream();
//将列表导成excelfileName为文件的具体路径自行设定也可为outputStream输出流//CertifyOrderDetailsExcel.class为上面配置的excel模板类
EasyExcel.write(fileName, CertifyOrderDetailsExcel.class)
.sheet(统计)
.relativeHeadRowIndex(0)
.doWrite(list);
方式二整体设置样式 public static T void writeExcel(HttpServletRequest request, HttpServletResponse response, ListT data, Class tClass, String name){try {name java.net.URLEncoder.encode(name, UTF-8).replaceAll(\\, %20);String dateStr String.valueOf(LocalDate.now().getMonthValue())-LocalDate.now().getDayOfYear();name namedateStr;//防止下载时中文乱码name new String(name.getBytes(StandardCharsets.UTF_8), StandardCharsets.ISO_8859_1);response.setCharacterEncoding(utf-8);//添加这个是防止前端拿不到Content-dispositionresponse.setHeader(Content-Disposition, attachment;filename name.xlsx);response.setHeader(Access-Control-Expose-Headers,Content-disposition);WriteCellStyle headWriteCellStyle new WriteCellStyle();WriteFont headWriteFont new WriteFont();headWriteFont.setFontHeightInPoints((short) 12);headWriteCellStyle.setWriteFont(headWriteFont);//内容样式策略WriteCellStyle contentWriteCellStyle new WriteCellStyle();contentWriteCellStyle.setVerticalAlignment(VerticalAlignment.CENTER);contentWriteCellStyle.setHorizontalAlignment(HorizontalAlignment.LEFT);contentWriteCellStyle.setBorderLeft(BorderStyle.THIN);contentWriteCellStyle.setBorderTop(BorderStyle.THIN);contentWriteCellStyle.setBorderRight(BorderStyle.THIN);contentWriteCellStyle.setBorderBottom(BorderStyle.THIN);//设置 自动换行contentWriteCellStyle.setWrapped(true);// 字体策略WriteFont contentWriteFont new WriteFont();// 字体大小contentWriteFont.setFontHeightInPoints((short) 12);contentWriteCellStyle.setWriteFont(contentWriteFont);// 这里需要设置不关闭流EasyExcelFactory.write(response.getOutputStream(), tClass).registerWriteHandler(new HorizontalCellStyleStrategy(headWriteCellStyle, contentWriteCellStyle)).autoCloseStream(Boolean.FALSE).sheet(毛坯反馈参数(越南)).doWrite(data);} catch (Exception e) {//log.error(文件导出失败,错误信息{},e);// 重置responseresponse.reset();response.setContentType(application/json);response.setCharacterEncoding(utf-8);try {response.getWriter();} catch (IOException ioException) {ioException.printStackTrace();}}}
