POI读取excel表格

前台使用ajaxFileUpload上传文件，后台使用POI处理：

js代码：

function improtMessage() {
$.messager.confirm('提示','确定您要导入配置？',function(r){   //jqueryEasyUI
if (r){

$.ajaxFileUpload({
url: path+'/systemConfigureController/importSysConfig.do',
secureuri: false,//异步
fileElementId: 'file',//上传控件ID
dataType: 'text',//返回的数据信息格式
success: function(data){

}
})
}
});
}

后台接收和POI处理代码：

private static int version2003 = 2003;
private static int version2007 = 2007;
private static int version = version2003;
/**
* 导入配置
* @param request
* @param response
* @throws IOException
*/

@RequestMapping("importSysConfig")
public void importData(HttpServletRequest request, HttpServletResponse response) throws IOException{
logger.info("**********into method importData*************");
// 设置上下文
CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver(
request.getSession().getServletContext());
// 检查form是否有enctype="multipart/form-data"
if (multipartResolver.isMultipart(request)) {
MultipartHttpServletRequest multiRequest = (MultipartHttpServletRequest) request;
Iterator<String> iter = multiRequest.getFileNames();
List objList = new ArrayList();
while (iter.hasNext()) {

MultipartFile file = multiRequest.getFile(iter.next());
logger.info("print out file:  "+file+"  fileName:  "+file.getName()+" fileSize: "+file.getSize());
version = (file.getName().endsWith(".xls") ? version2003 : version2007);
if (version == 2003) {
POIFSFileSystem fs = new POIFSFileSystem(file.getInputStream());
HSSFWorkbook wb = new HSSFWorkbook(fs);
HSSFSheet sheet = wb.getSheetAt(0);
<pre name="code" class="html">                     objList = readCountryExcel(sheet);

logger.info("print out readExcel: " + objList); }else if (version == 2007){ XSSFWorkbook hwk = new XSSFWorkbook(file.getInputStream());// 将is流实例到 一个excel流里 XSSFSheet sheet = hwk.getSheetAt(0);// 得到book第一个工作薄sheet objList = readCountryExcel(sheet);
logger.info("print out readExcel: " + objList); } }//业务逻辑代码，调用service } response.getWriter().print("1");}

public List<Country> readCountryExcel(Sheet sheet){
List<Country> countryList = new ArrayList<Country>();
int rowNum = sheet.getPhysicalNumberOfRows();  //获得总共的行数
Country country = null;
for (int i =1; i<rowNum; i++){
country = new Country();
Row row = sheet.getRow(i);   //得到第i行数据
Cell c = null;
if (null != row){
c = row.getCell(0);
if (null != c){
if (c.getCellType() == c.CELL_TYPE_NUMERIC) {
c.setCellType(c.CELL_TYPE_STRING);
country.setCountry(c.getStringCellValue());
}else{
country.setCountry(c.getStringCellValue());
}
}
c = row.getCell(1);
if (null != c){
if (c.getCellType() == c.CELL_TYPE_NUMERIC) {
c.setCellType(c.CELL_TYPE_STRING);
country.setProvince(c.getStringCellValue());
}else {
country.setProvince(c.getStringCellValue());
}
}
c = row.getCell(2);
if (null != c){
if (c.getCellType() == c.CELL_TYPE_NUMERIC) {
c.setCellType(c.CELL_TYPE_STRING);
country.setZone(c.getStringCellValue());
}else {
country.setZone(c.getStringCellValue());
}
}
c = row.getCell(3);
if (null != c){
if (c.getCellType() == c.CELL_TYPE_NUMERIC) {
c.setCellType(c.CELL_TYPE_STRING);
country.setCode(c.getStringCellValue());
}else {
country.setCode(c.getStringCellValue());
}
}
}
countryList.add(country);
logger.info("print out read Excel row" + i + "Country: " + country);
}
return countryList;
}
