Excel導(dǎo)入

/** * excel 文件導(dǎo)入* @param inputStream* @param clazz*/ public static List<? extends Object> importExcel(InputStream inputStream, Class clazz,List<? extends Object> list) {try {return EasyExcel.read(inputStream).head(clazz).sheet(0).doReadSync();} catch (Exception e) {e.printStackTrace();}return null; }

Excel導(dǎo)出

/*** excel 文件導(dǎo)出*/ public static void exportExcel(OutputStream outputStream, Class clazz, List<? extends Object> list) {EasyExcel.write(outputStream,clazz).excelType(ExcelTypeEnum.XLSX).sheet("sheet1").doWrite(list); }

功能測試

導(dǎo)入測試

// 導(dǎo)入上傳 String filePath = "F:\\Download\\inputExcel.xlsx"; List<UserInfoBean> list = new ArrayList<>();try {InputStream inputStream = new FileInputStream(new File(filePath));list = (List<UserInfoBean>) importExcel(inputStream,UserInfoBean.class,list);System.out.println("輸出:" + list.toString());} catch (FileNotFoundException e) {e.printStackTrace();}

導(dǎo)出測試

// 導(dǎo)出下載 OutputStream outputStream = null; List<UserInfoBean> list1 = new ArrayList<>(); for (int i = 0; i < 5; i++ ){UserInfoBean userInfoBean = new UserInfoBean();userInfoBean.setUserId("id_" + i);userInfoBean.setUserName("name_" + i);userInfoBean.setGender("男" + i);userInfoBean.setHeight("17" + i + "cm");userInfoBean.setPhoneNum("12345"+ i);list1.add(userInfoBean); } try {outputStream = new FileOutputStream(new File("F:\\Download\\outExcel.xlsx"));exportExcel(outputStream, UserInfoBean.class, list1); } catch (Exception e) {e.printStackTrace(); } finally {try {if (null != outputStream) {outputStream.close();}} catch (IOException e) {e.printStackTrace();}}

結(jié)果查看

輸出:
[
UserInfoBean{userId=‘1’, userName=‘jack’, phoneNum=‘1234567’, gender=‘男’, height=‘165cm’},
UserInfoBean{userId=‘2’, userName=‘lisi’, phoneNum=‘2345678’, gender=‘女’, height=‘175cm’},
UserInfoBean{userId=‘3’, userName=‘zhangsan’, phoneNum=‘3456789’, gender=‘男’, height=‘170cm’}
