利用poi从excel中导入数据到数据库
最近遇到了从excel向数据库导入数据的情况，利用POI技术实现数据的导入：
前台页面代码如下：
<input type="file" name="" id="file" style="width: 165px"> <button type="button" onclick="improtMessage()" style="width: 48px">导入</button> <button type="button" onclick="exportMessage()" style="width: 48px">导出</button> <button type="button" onclick="dowloadMessage()" style="width: 70px">模板下载</button>
前台js代码：
/**
* 导入配置
*/
function improtMessage() {
$.messager.confirm('提示','确定您要导入配置？',function(r){
if (r){
var fileName=$('#file').val();
var file=fileName.split(".")[0];
$('#file').attr("name",$('#file').val());
$.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){
$.messager.alert('提示','导入配置成功！');
if(file == "小区"){
selectVillageMessage();
}if(file == "国家地区码"){
selectCountryMessage();
}if(file == "位置区"){
selectPositionMessage();
}if(file == "终端信息"){
selectIMEIMessage();
}
}
})
}
});
}
控制层代码如下：
/**
* 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();
while (iter.hasNext()) {
List objList = new ArrayList();
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);
readObject(file.getName(), 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
readObject(file.getName(), sheet);
logger.info("print out readExcel: " + objList);
}
}
}
response.getWriter().print("1");
}

servicedao的代码：
public void addCountryMEessage(List<Country> list); public void addIMEIMessage(List<IMEI> list); public void addPositionMessage(List<Position> list); public void addVillageMessage(List<Village> list);
servicedaoimpl的代码：
@Override
public void addCountryMEessage(List<Country> list) {
countryDao.addCountryMessage(list);
}
@Override
public void addIMEIMessage(List<IMEI> list) {
imeiDao.addIMEIMessage(list);

xml中sql的代码如下：
<!-- 向数据库imei中插入数据 -->
<insert id="addIMEIMessage" parameterType="java.util.List">
insert into imei
(IMEI, imei_version, imei_name, imei_factory_name)
values
<foreach collection="list" item="item" index="index" separator="," >

</foreach>
</insert>
