업로드한 엑셀 파일 데이터 읽어오기

지극히 개인적인 소스- ㅅ-.....

Struts1 을 사용했는데 formfile이 file 로 형변환이 되지 않았따 ㅠㅠㅠㅠㅠ

불러온 파일 데이터를 다시 읽어와서 file 객체로

저장한담에  excel 데이터를 읽어와따..

 

에러
Corrupt form data: premature ending
이유:
스트럿츠에서 멀티파트를 알아서 처리해줘요
그런데 POI로 작업하려는 상황에서 멀티파트로 리퀘스트를 다시 처리하려고 하면 이미 한번 파싱된 리퀘스트를 또 처리하려고 해서 나는 에러니까
FormFile 객체는 스트럿츠에서 지원해주는 거고
File은 java 에서 기본적으로 지원해주는거니까

 

public static List<?> readExcel(String type, FormFile uploadFile,

String path)

{

List<?> newList = null;

ArrayList<String> temp = new ArrayList<String>();

int cn = 0;

InputStream is = null;

FileInputStream fis = null;

byte[] fileBArray = null;

String fullname = path + "\\" + uploadFile.getFileName();

try

{

fileBArray = uploadFile.getFileData();

fis = new FileInputStream(new File(fullname));

fis.read(fileBArray);

is = fis;

}

catch (Exception e)

{

String error = "Cannot get input stram";

temp.add(error);

return temp;

}

try

{

Workbook wb = null;

try

{

wb = WorkbookFactory.create(fis);

}

catch (Exception e1)

{

try

{

// I have tried fis and is as well and I still throw an exception

wb = new XSSFWorkbook(fullname);

}

catch (Exception e2)

{

// doesn't even make it here - it throws an exception but is never caught

try

{

wb = new HSSFWorkbook(is);

}

catch (Exception e3)

{

String error = "problem with workbook: "

+ e3.getMessage();

temp.add(error);

return temp;

}

}

}

}

}
