java 利用autopoi進行xls文件（帶圖片附件）導入導出

先看效果：

maven依賴：

<!-- AutoPoi Excel工具類-->
<dependency>
    <groupId>org.jeecgframework</groupId>
    <artifactId>autopoi-web</artifactId>
</dependency>

PmsSupplierParam.java

@Data
public class PmsSupplierParam implements Serializable {

	private static final long serialVersionUID = 1L;

	@ApiModelProperty(value = "創建時間", hidden = true)
	@Excel(name = "建檔時間", orderNum = "5", format = "yyyy-MM-dd HH:mm:ss", width = 25)
	private Date createTime;

	@ApiModelProperty(value = "供應商名稱", example = "供應商名稱")
	@Excel(name = "供應商名稱", width = 40, orderNum = "0")
	private String name;

	@ApiModelProperty(value = "聯繫人", example = "聯繫人")
	@Excel(name = "聯繫人", width = 20, orderNum = "1")
	private String contact;

	@ApiModelProperty(value = "聯繫人電話", example = "聯繫人電話")
	@Excel(name = "聯繫人電話", width = 20, orderNum = "2")
	private String contactPhone;

	@ApiModelProperty(value = "備註", example = "備註")
	@Excel(name = "備註", width = 60, orderNum = "4")
	private String remark;

	@ApiModelProperty(value = "詳細地址", example = "詳細地址")
	@Excel(name = "單位地址", width = 40, orderNum = "3")
	private String address;

}

Controller新增以下代碼：

@ApiOperation(value = "導出", produces = "application/octet-stream")
@RequestMapping(value = "/exportXls", method = RequestMethod.GET)
public ModelAndView exportXls(HttpServletRequest request, HttpServletResponse response) {
	ModelAndView mv = new ModelAndView(new JeecgEntityExcelView());
	List exportListData = getListData();

	// 導出文件名稱
	mv.addObject(NormalExcelConstants.FILE_NAME, "供應商信息");
	// 註解對象Class
	mv.addObject(NormalExcelConstants.CLASS, PmsSupplierParam.class);
	// 自定義表格參數
	mv.addObject(NormalExcelConstants.PARAMS, new ExportParams("供應商信息", "供應商信息"));
	// 導出數據列表
	mv.addObject(NormalExcelConstants.DATA_LIST, exportListData);
	return mv;
}

/**
 * 生成假數據，真實開發中這裏數據一般來自數據庫
 * 
 * @return
 */
@SuppressWarnings("unused")
private List getListData() {
	List<PmsSupplierParam> list = new ArrayList<>();
	for (int i = 0; i < 30; i++) {
		PmsSupplierParam excelEntity = new PmsSupplierParam();
		excelEntity.setName("名稱" + i);
		excelEntity.setContact("聯繫人" + i);
		excelEntity.setContactPhone("聯繫電話" + i);
		excelEntity.setAddress("地址" + i);
		excelEntity.setRemark("備註" + i);
		list.add(excelEntity);
	}
	System.out.println(list.toString());
	return list;
}

@ApiOperation(value = "導入")
@PostMapping("/importXls")
@ResponseBody
public String importExcel(MultipartFile myFileNames, Principal principal)
		throws Exception {
	ImportParams params = new ImportParams();
	// 表格標題所在行，計數從0開始
	params.setTitleRows(1);
	// head頭部所在行，計數從0開始
	params.setHeadRows(0);
	// 表格sheet數量
	// params.setSheetNum(9);
	// 最好不要設置爲true，否則導入一次excel服務器會重啓一次，原因不明
	// params.setNeedSave(false);
	InputStream inputStream = myFileNames.getInputStream();
	List<PmsSupplierParam> list = ExcelImportUtil.importExcel(inputStream, PmsSupplierParam.class, params);
	return list.toString();
}

帶圖片附件的特殊說明：

@Excel(name = "圖片地址",type=2,imageType=4)
private String picture;
