Apache POI实现数据的Excel导入
得到上传的MultipartFile 文件转换成FileInputStream ，将输入流传入importExcelX解析返回List,然后遍历插入数据库。
ExportDataController.java
@RequestMapping(value = "ImportExcelProduct.do",method = RequestMethod.POST)
public String ImportExcelProduct(@RequestParam("files") MultipartFile file){
BasicProductMsg basicProductMsg = new BasicProductMsg();
String fileName =file.getOriginalFilename() ;
String returnStr = StringUtil.RETURN_ERROR_DATA_FORMAT;//这个是一个返回提示内容：上传格式错误！
//文件不为空并且后缀等于xlsx就将上传的文件写入临时的文件夹中
if (!file.isEmpty() && fileName.endsWith(".xlsx")) {
try {
//得到文件的输入流
FileInputStream fis = (FileInputStream) file.getInputStream();
//解析Excel后得到的 List集合
List

导入的文件列头要和实体类一样，如果要列头是中文在就在帮助类58行下面写一个判断如果 headers[j] =“苹果”，name head = "apple"
