利用easy excel 实现文件导出

一.创建实体类

package com.siact.product.jwp.module.report.dto;import com.alibaba.excel.annotation.ExcelProperty;
import com.alibaba.excel.annotation.write.style.ColumnWidth;
import com.alibaba.excel.annotation.write.style.ContentRowHeight;
import com.alibaba.excel.annotation.write.style.HeadRowHeight;
import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;/*** @Description:*/
@Data
@AllArgsConstructor
@NoArgsConstructor
@ContentRowHeight(30)
@HeadRowHeight(25)
@ColumnWidth(25)
public class PatrolProcessDTO {@ExcelProperty(index = 0,value = "序号")private int orderNum;@ExcelProperty(index = 1,value = "工单名称")private String workOrderName;@ExcelProperty(index = 2,value = "巡检路线")private String patrolRoute;@ExcelProperty(index = 3,value = "维修技师")private String maintenanceUserName;@ExcelProperty(index = 4,value = "打点情况")private String content;@ExcelProperty(index = 5,value = "处理结果（工单状态）")private String workOrderSolveStatusName;@ExcelProperty(index = 6,value = "维修技师处理时长")private String maintenanceTime;@ExcelProperty(index = 7,value = "维修班长确认时长")private String confirmTime;@ExcelProperty(index = 8,value = "总用时")private String workOrderSpendTime;}

二、引入合并策略

三、引入其他样式

//                cellStyleList.add(CellStyleModel.createBorderCellStyleModel("巡检工单", i, j, BorderStyle.THIN, IndexedColors.BLACK));//设置换行策略cellStyleList.add(CellStyleModel.createWrapTextCellStyleModel("巡检工单", i, j, true));}}//向会话写入try {response.setContentType("application/vnd.ms-excel");response.setCharacterEncoding("utf-8");String fileName = URLEncoder.encode("巡检工单", "UTF-8"); //.replaceAll("\\+", "%20")response.setHeader("Content-disposition", "attachment;filename=" + fileName + ".xlsx");EasyExcel.write(response.getOutputStream(), PatrolProcessDTO.class).excelType(ExcelTypeEnum.XLSX).autoCloseStream(Boolean.TRUE)// 添加自定义处理程序，相当于Spring的AOP切面.registerWriteHandler(new ExcelFillCellMergeStrategy(0, 8, new ArrayList<>())).registerWriteHandler(new CustomCellStyleHandler(cellStyleList)).sheet("巡检工单").doWrite(allContentList);} catch (Exception e) {log.error("导出出错-{}", ExceptionUtils.getStackTrace(e));renderString(response, JSON.toJSONString(new ResultInfo().error(SystemError.SYS_10055)));}}

备注：由于合并策略是自定义得，在效率上没法保证，当牵扯到大数据量合并导出时，用时较长。
