前言

Easy Excel 真的很好用，今天就为大家介绍如何使用它做动态导出。

一、上菜

1.添加依赖

	<dependency>
      <groupId>com.alibaba</groupId>
      <artifactId>easyexcel</artifactId>
      <version>2.2.5</version>
      <exclusions>
        <exclusion>
          <artifactId>poi</artifactId>
          <groupId>org.apache.poi</groupId>
        </exclusion>
      </exclusions>
    </dependency>

2.核心编码

@ApiOperation(httpMethod = "POST", value = "下载路线规划报表", notes = "下载路线规划报表", produces = MediaType.APPLICATION_JSON_VALUE)
    @PostMapping(value = "/download/route-report")
    public void downloadRouteReport(@RequestBody @Valid RouteReportDto reportDto, HttpServletResponse response) throws IOException {
        String sheetName = "路线规划报表";
        try {
            response.setContentType("application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");
            response.setCharacterEncoding("utf-8");
            // 这里URLEncoder.encode可以防止中文乱码 当然和easyexcel没有关系
            String fileName = URLEncoder.encode("路线规划报表", "UTF-8").replaceAll("\\+", "%20");
            response.setHeader("Content-disposition", "attachment;filename*=utf-8''" + fileName + ".xlsx");
            response.setHeader("filename", fileName + ".xlsx");
            RouteReportDto dto = getFormatDate(reportDto);
            
            // 查询数据
            List<RouteReport> list = routeReportService.getRouteReportInfoExcel(dto);
            List<RouteReportExcel> excelList = new ArrayList<>();
            // 数据格式包装
            statusExcel(excelList,list);
            // 这里需要设置不关闭流
            EasyExcel.write(response.getOutputStream(), RouteReportExcel.class).autoCloseStream(Boolean.FALSE).sheet(sheetName)
                        .doWrite(excelList0);

        } catch (Exception e) {
            // 重置response
            log.error("导出异常!!!",e);
            response.reset();
            response.setContentType("application/json");
            response.setCharacterEncoding("utf-8");
            Map<String, String> map = new HashMap<>();
            map.put("status", "failure");
            map.put("message", "下载文件失败" + e.getMessage());
            response.getWriter().println(JSON.toJSONString(map));
        }

    }

3.导出字段属性介绍

// RouteReportExcel 

 @ExcelProperty  在每个需要导出的字段上面加上导出时需要展示的名称即可。
 直接整一个组合型，可以灵活使用，不用拘泥于一种格式


@Data
@ApiModel(value = "报表数据")
public class RouteReportExcel implements Serializable {

    @ExcelProperty({"时间", "自然月"})
    @ApiModelProperty(value = "年月")
    private String planMonth;

    @ExcelProperty({"组织", "行销公司"})
    @ApiModelProperty(value = "公司")
    private String company;

    @ExcelProperty({"组织", "营业部"})
    @ApiModelProperty(value = "营业部")
    private String dept;

    @ExcelProperty({"组织", "营业所"})
    @ApiModelProperty(value = "营业所")
    private String orgName;

    @ExcelProperty({"组织", "业代类型"})
    @ApiModelProperty(value = "业代类型")
    private String salesTypeName;

    @ExcelProperty({"组织", "业代人员"})
    @ApiModelProperty(value = "业代人员")
    private String empName;

    @ExcelProperty({"规划进度", "方案完成"})
    @ApiModelProperty(value = "方案完成")
    private String planDownloadStatus;

    @ExcelProperty({"规划进度", "方案上传SFT"})
    @ApiModelProperty(value = "方案上传SFT")
    private String planUploadStatus;
}
