1.head引用
<script type="text/javascript" src="<%=request.getContextPath() %>/js/ajaxfileupload.js"></script>
2.重写下面方法
function ajaxFileUpload() { var elementIds=["flag"]; //flag为id、name属性名 $.ajaxFileUpload({ url: ‘importSemzzTongjiExcel.action‘, type: ‘post‘, secureuri: false, //一般设置为false fileElementId: ‘file‘, // 上传文件的id、name属性名 dataType: ‘text‘, //返回值类型，一般设置为json、application/json elementIds: elementIds, //传递参数到服务器 success: function(data, status){ alert("上传成功"); }, error: function(data, status, e){ alert(e); } }); }
3.写jsp上传jsp代码
<form id ="importExcel" action="importSemzzTongjiExcel.action" method="post" enctype="multipart/form-data"> <input type="file" name ="file" id ="file"> <input type="button" value="上传excel" onclick="ajaxFileUpload()"> </form>
4.对应的action代码
@Value("#{config[‘winFileUrl‘]}")
private String winFileUrl;
@Value("#{config[‘linFileUrl‘]}")
private String linFileUrl;
/**
*
* @param excelFileName
* @param month
* @throws Exception
*/
@RequestMapping("importSemzzTongjiExcel")
public String importSemzzTongjiExcel(String month,@RequestParam MultipartFile file) throws Exception{
if(month == null){
month =CalendarUtil.getShotDateToString(CalendarUtil.getLastDateOfMonth(new Date()));
}
System.out.println(System.getProperties().getProperty("os.name"));
String fileUrl ="";
try {
String sysName =System.getProperties().getProperty("os.name");
if(sysName.startsWith("Windows")){
fileUrl =winFileUrl+file.getOriginalFilename();
}else{
fileUrl=linFileUrl+file.getOriginalFilename();
}
file.transferTo(new File(fileUrl));
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
List<Map<String,Object>> list =service.getsemzzList(month,null,null);
InputStream input;
try {
input = new FileInputStream(fileUrl);
POIFSFileSystem fs = new POIFSFileSystem(input);
HSSFWorkbook wb = new HSSFWorkbook(fs);
HSSFSheet sheet = wb.getSheetAt(0);
int rowNum = sheet.getLastRowNum();
for(int i=1;i<=rowNum;i++){
HSSFRow row= sheet.getRow(i);
HSSFCell cell1 =row.getCell(0);
String userName =null;
if(cell1!=null){
userName =cell1.getStringCellValue();
for (Map<String,Object> map : list) {
String userNameSql =(String) map.get("username");
if(userName.equals(userNameSql)){
Double xindanaccountstc = Double.parseDouble(map.get("xindanaccountstc").toString());
Double xudanaccountstc = (Double.parseDouble(map.get("xudanaccountstc").toString()));
Double tichengheji =xindanaccountstc+xudanaccountstc;
String gangwei = null;
String position = null;
Double dyrealjixiaoxishu =0D;
HSSFCell cell2 =row.getCell(1);
if(cell2!=null){
gangwei=cell2.getStringCellValue();
}
HSSFCell cell3 =row.getCell(2);
if(cell3!=null){
position=cell3.getStringCellValue();
}
HSSFCell cell4 =row.getCell(3);
if(cell4!=null){
dyrealjixiaoxishu =cell4.getNumericCellValue();
}
service.updateData(userNameSql, month, gangwei, position, dyrealjixiaoxishu,tichengheji);
break;
}
}
}
}
// Iterate over each row in the sheet
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
System.out.println("end...");
return null;
}
