一.pom.xml中导入所需要的依赖:
<!--读取excel文件--> //操作03版的Excel,即以.xls结尾的excel表 <dependency> <groupId>org.apache.poi</groupId> <artifactId>poi</artifactId> <version>3.17</version> </dependency> //操作07版的Excel,即以.xlsx结尾的Excel表 <dependency> <groupId>org.apache.poi</groupId> <artifactId>poi-ooxml</artifactId> <version>3.17</version> </dependency>
二.编写前端代码:
//HTML:
<input id="articleImageFile" name="excelFile" type="file" class="form-control" style=" 300px; display: inline;" /> <a class="btn btn-warning" id = "import" onclick="importExcel()" shiro:hasPermission="system:student:import"> <i class="fa fa-upload"></i> 导入</a>
//js代码:
<script> function importExcel() { var formData = new FormData(); var name = $("#articleImageFile").val(); formData.append("file", $("#articleImageFile")[0].files[0]); formData.append("name", name);//这个地方可以传递多个参数 $.ajax({ url: '/system/student/importExcel', type: 'POST', async: false, data: formData, // 告诉jQuery不要去处理发送的数据 processData: false, // 告诉jQuery不要去设置Content-Type请求头 contentType: false, beforeSend: function () { console.log("正在进行,请稍候"); }, success: function (responseStr) { if (responseStr == "上传成功") { alert("导入成功"); } else { alert("导入失败"); } } }); } </script>
三.controller层代码:
@RequestMapping("/importExcel") @ResponseBody public String importExcel(@RequestParam("file") MultipartFile file, HttpServletRequest request, HttpServletResponse response) { System.out.println("file"+file.getSize()); try { // @RequestParam("file") MultipartFile file 是用来接收前端传递过来的文件 // 1.创建workbook对象,读取整个文档 InputStream inputStream = file.getInputStream(); //POIFSFileSystem poifsFileSystem = new POIFSFileSystem(inputStream); XSSFWorkbook wb = new XSSFWorkbook(inputStream); // 2.读取页脚sheet XSSFSheet sheetAt = wb.getSheetAt(0); // 3.循环读取某一行 int index = 0; for (Row row : sheetAt) { // 4.读取每一行的单元格 if (index == 0) { index++; continue; }
//创建一个学生对象 SysStudent student = new SysStudent();
//将Excel表中单元格的值与学生对象的值对应 student.setName(row.getCell(0).getStringCellValue());
//因为学号是数字,Excel默认是数字类型,我的数据库是字符串类型,所以需要设置下类型 row.getCell(1).setCellType(CellType.STRING); student.setStuId(row.getCell(1).getStringCellValue()); student.setIdentity(row.getCell(2).getStringCellValue()); student.setDescription(row.getCell(3).getStringCellValue()); student.setProvince(row.getCell(4).getStringCellValue());
//将对应好的学生对象存入数据库中 sysStudentService.insertSysStudent(student); row.getCell(0).setCellType(CellType.STRING); String stringCellValue = row.getCell(0).getStringCellValue(); row.getCell(1).setCellType(CellType.STRING); String stringCellValue2 = row.getCell(1).getStringCellValue(); row.getCell(2).setCellType(CellType.STRING); String stringCellValue3 = row.getCell(2).getStringCellValue(); row.getCell(3).setCellType(CellType.STRING); String stringCellValue4 = row.getCell(3).getStringCellValue(); row.getCell(4).setCellType(CellType.STRING); String stringCellValue5 = row.getCell(4).getStringCellValue(); // 写多少个具体看大家上传的文件有多少列..... // 后台测试是否读取到数据,及数据的正确性 System.out.println(stringCellValue); System.out.println(stringCellValue2); System.out.println(stringCellValue3); System.out.println(stringCellValue4); System.out.println(stringCellValue5); } } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } return "上传成功"; }
