springboot整合easypoi实现简单的excel导出导入

1、pom.xml配置

org.jeecg easypoi-base 2.3.1 org.jeecg easypoi-web 2.3.1 org.jeecg easypoi-annotation 2.3.1

2、导出功能

controller层：

@RequestMapping("/downloadExcel") public void download(HttpServletRequest request, HttpServletResponse response) throws Exception { // 告诉浏览器用什么软件可以打开此文件 response.setHeader("content-Type", "application/vnd.ms-excel"); // 下载文件的默认名称 response.setHeader("Content-Disposition", "attachment;filename=" + URLEncoder.encode("用户数据表","UTF-8") + ".xls"); //编码 response.setCharacterEncoding("UTF-8"); List list = userService.findAllUser();//获得用户 Workbook workbook = ExcelExportUtil.exportExcel(new ExportParams(), User.class, list); workbook.write(response.getOutputStream()); }

service层：

@Override public List findAllUser() { return userMapper.findAllUser(); }

dao层：

SELECT id,name FROM t_user

3、导入功能

controller层：

@RequestMapping("/excelImport") @ResponseBody public String excelImport() { ImportParams importParams = new ImportParams(); ImportParams params = new ImportParams(); params.setHeadRows(2);   try { List objects = ExcelImportUtil.importExcel(new File("F:\\aa.xls"), User.class, importParams); userService.importUser(objects); System.out.println(objects); return "ok"; }catch (Exception e){ e.printStackTrace(); return "no";   }   }

service层：

/** * 导入User * @param objects */ @Override public void importUser(List objects) {   for (User user : objects) { userMapper.importUser(user); }     }

dao层：

INSERT INTO t_user(name) VALUES(#{name})
