easyexcell导出专题

本文介绍阿里巴巴导出工具easyexcell导出excell

介绍一下几种导出情况

1，导出单个sheet，无模型方式

2，导出单个sheet，模型方式

3，导出多个sheet，无模型方式

4，导出多个sheet，模型方式

5，导出多个sheet，到本地指定目录下

以上导出方式区别

1，（1-4）自动下载到c盘默认路径并创建文件；方式5，下载到指定目录及文件下

区别在于输出流的的创建

2，无模型方式，模型方式区别

2.1，前者不需要定义导出实体类，手动封装数表头信息及导出数据

且封装表头数据方式有两种，sheet和table

1）sheet

封装表头

  Sheet sheetMing = new Sheet(1, 0);sheetMing.setSheetName("沈明内购方案信息");//设置列List<List<String>> titlesMing = new ArrayList<>();titlesMing.add(Arrays.asList("方案编号"));titlesMing.add(Arrays.asList("主机厂"));titlesMing.add(Arrays.asList("方案名称"));titlesMing.add(Arrays.asList("可购品牌"));titlesMing.add(Arrays.asList("可购车型"));titlesMing.add(Arrays.asList("附件"));titlesMing.add(Arrays.asList("状态"));titlesMing.add(Arrays.asList("备注"));titlesMing.add(Arrays.asList("审批人"));titlesMing.add(Arrays.asList("审批时间"));titlesMing.add(Arrays.asList("审批意见"));titlesMing.add(Arrays.asList("创建人"));titlesMing.add(Arrays.asList("创建时间"));titlesMing.add(Arrays.asList("修改人"));titlesMing.add(Arrays.asList("修改日期"));sheetMing.setHead(titlesMing);

注意表头每一列用List<String>包装，setHead()入参是表头集合的集合

  public void setHead(List<List<String>> head) {this.head = head;}

封装数据

  List<List<String>> dataMing = new ArrayList<>();for (PlanVO object : listMing) {List<String> list = new ArrayList<>();list.add(object.getCode());list.add(object.getBrandName());list.add(object.getName());list.add(object.getBrandNameList());list.add(object.getVehicleTypeName());list.add(object.getFileName().toString());list.add(object.getStatusName());list.add(object.getDescription());list.add(object.getApprovalUser());list.add(DateUtil.getNormTime(object.getApprovalTime()));list.add(object.getApprovalResult());list.add(object.getCreateUser());list.add(DateUtil.getNormTime(object.getCreateTime()));list.add(object.getUpdateUser());list.add(DateUtil.getNormTime(object.getUpdateTime()));dataMing.add(list);}

写入导出数据

  public ExcelWriter write0(List<List<String>> data, Sheet sheet, Table table) {excelBuilder.addContent(data, sheet, table);return this;}

2) table

 private void excellReport(List<PlanVO> planVO, HttpServletResponse servletResponse) {ExcelWriter writer = new ExcelWriter(getOutputStream("已发布内购方案", servletResponse), ExcelTypeEnum.XLSX);//设置SHEETSheet sheet = new Sheet(1, 0);sheet.setSheetName("sheet1");//设置列Table table = new Table(1);List<List<String>> titles = new ArrayList<>();titles.add(Arrays.asList("方案编号"));titles.add(Arrays.asList("主机厂"));titles.add(Arrays.asList("方案名称"));titles.add(Arrays.asList("可购品牌"));titles.add(Arrays.asList("可购车型"));titles.add(Arrays.asList("附件"));titles.add(Arrays.asList("状态"));titles.add(Arrays.asList("备注"));titles.add(Arrays.asList("审批人"));titles.add(Arrays.asList("审批时间"));titles.add(Arrays.asList("审批意见"));titles.add(Arrays.asList("创建人"));titles.add(Arrays.asList("创建时间"));titles.add(Arrays.asList("修改人"));titles.add(Arrays.asList("修改日期"));table.setHead(titles);// 封装数据List<List<String>> userList = new ArrayList<>();for (PlanVO object : planVO) {List<String> list = new ArrayList<>();list.add(object.getCode());list.add(object.getBrandName());list.add(object.getName());list.add(object.getBrandNameList());list.add(object.getVehicleTypeName());list.add(object.getFileName().toString());list.add(object.getStatusName());list.add(object.getDescription());list.add(object.getApprovalUser());list.add(DateUtil.getNormTime(object.getApprovalTime()));list.add(object.getApprovalResult());list.add(object.getCreateUser());list.add(DateUtil.getNormTime(object.getCreateTime()));list.add(object.getUpdateUser());list.add(DateUtil.getNormTime(object.getUpdateTime()));userList.add(list);}writer.write0(userList, sheet, table);writer.finish();}

写入数据调用方法

 public ExcelWriter write0(List<List<String>> data, Sheet sheet, Table table) {excelBuilder.addContent(data, sheet, table);return this;}

2.2，后者需要定义导出实体类，指定表头及顺序

实体类

@EqualsAndHashCode(callSuper = true)
@Data
public class TableHeaderExcelProperty extends BaseRowModel {/*** value: 表头名称* index: 列的号, 0表示第一列*/@ExcelProperty(value = "姓名", index = 0)private String name;@ExcelProperty(value = "年龄", index = 1)private int age;@ExcelProperty(value = "学校", index = 2)private String school;}

调用方法

 public ExcelWriter write(List<? extends BaseRowModel> data, Sheet sheet) {excelBuilder.addContent(data, sheet);return this;}

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------上面大概介绍了一下，下面详细介绍每一种方式

一，导出单个sheet，无模型方式

sheet封装表头

  private void excellReport(List<PlanVO> planVO, HttpServletResponse servletResponse) {ExcelWriter writer = new ExcelWriter(getOutputStream("已发布内购方案", servletResponse), ExcelTypeEnum.XLSX);//设置SHEETSheet sheet = new Sheet(1, 0);sheet.setSheetName("sheet1");//设置列Table table = new Table(1);List<List<String>> titles = new ArrayList<>();titles.add(Arrays.asList("方案编号"));titles.add(Arrays.asList("主机厂"));titles.add(Arrays.asList("方案名称"));titles.add(Arrays.asList("可购品牌"));titles.add(Arrays.asList("可购车型"));titles.add(Arrays.asList("附件"));titles.add(Arrays.asList("状态"));titles.add(Arrays.asList("备注"));titles.add(Arrays.asList("审批人"));titles.add(Arrays.asList("审批时间"));titles.add(Arrays.asList("审批意见"));titles.add(Arrays.asList("创建人"));titles.add(Arrays.asList("创建时间"));titles.add(Arrays.asList("修改人"));titles.add(Arrays.asList("修改日期"));table.setHead(titles);// 封装数据List<List<String>> userList = new ArrayList<>();for (PlanVO object : planVO) {List<String> list = new ArrayList<>();list.add(object.getCode());list.add(object.getBrandName());list.add(object.getName());list.add(object.getBrandNameList());list.add(object.getVehicleTypeName());list.add(object.getFileName().toString());list.add(object.getStatusName());list.add(object.getDescription());list.add(object.getApprovalUser());list.add(DateUtil.getNormTime(object.getApprovalTime()));list.add(object.getApprovalResult());list.add(object.getCreateUser());list.add(DateUtil.getNormTime(object.getCreateTime()));list.add(object.getUpdateUser());list.add(DateUtil.getNormTime(object.getUpdateTime()));userList.add(list);}writer.write0(userList, sheet, table);writer.finish();}

创建输出流

 /*** 导出文件时为Writer生成OutputStream*/private static OutputStream getOutputStream(String fileName, HttpServletResponse response) {//创建本地文件String filePath = fileName + ".xlsx";File dbfFile = new File(filePath);try {if (!dbfFile.exists() || dbfFile.isDirectory()) {dbfFile.createNewFile();}fileName = new String(filePath.getBytes(), "ISO-8859-1");response.addHeader("Content-Disposition", "filename=" + fileName);return response.getOutputStream();} catch (IOException e) {throw new ExcelException("创建文件失败！");}}

二，导出单个sheet，模型方式

 @org.junit.Testpublic void writeWithTemplate() {String filePath = "D:\\share\\model.xlsx";List<TableHeaderExcelProperty> data = new ArrayList<>();for (int i = 0; i < 2; i++) {TableHeaderExcelProperty tableHeaderExcelProperty = new TableHeaderExcelProperty();tableHeaderExcelProperty.setName("cmj" + i);tableHeaderExcelProperty.setAge(22 + i);tableHeaderExcelProperty.setSchool("清华大学" + i);data.add(tableHeaderExcelProperty);}ExcelUtil.writeWithTemplate(filePath, data);}

详细方法见工具类

三，导出多个sheet，无模型方式和有模型方式

效果图

Controller

    /*** 导出多个sheet 且表头，内容不同* 无模型方式* @param servletResponse* @param request*/@RequestMapping(value = "/export/duogeSheet")@LoggerManage(description = "导出多个sheet")public void exportDuogeSheet(HttpServletResponse servletResponse, BaseRequestModel request) {try {excelDemoSercice.exportDuogeSheet(servletResponse, request);} catch (Exception e) {e.printStackTrace();}}/*** 导出多个sheet 且表头，内容不同* 有模型方式* @param servletResponse*/@RequestMapping(value = "/export/duogeSheetModel")@LoggerManage(description = "导出多个sheet，模型方式")public void exportDuogeSheetModel(HttpServletResponse servletResponse) {try {excelDemoSercice.exportDuogeSheetModel(servletResponse);} catch (Exception e) {e.printStackTrace();}}
