xlsx excel generation - 从未见过这个

Question

在这里需要你的帮助......我最近一直致力于基于xls或xlsx选项生成excel文档。早些时候默认是xls。但是，如果以xlsx格式生成excel工作表，我将面临以下错误。

 Caused by: **java.lang.reflect.InvocationTargetException**
SystemErr     R    at sun.reflect.GeneratedConstructorAccessor193.newInstance(Unknown Source)
SystemErr     R    at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:57)

SystemErr     R    **at org.apache.poi.xssf.model.SharedStringsTable.<init>**(SharedStringsTable.java:102)

代码段：

public String getFilename(String formatType){
Workbook workBook = null;
if((".xlsx").equalsIgnoreCase(formatType))
{
  workBook = new XSSFWorkbook();

}
else
{
  workBook = new HSSFWorkbook();    

}

CreationHelper createHelper = workBook.getCreationHelper();

String sb= FormDetails.getFileNm();

if(formatType.equalsIgnoreCase(".xls"))
  {
     sb=sb.replace(".xlsx",".xls" );
}

  FileInputStream file= new FileInputStream(path+"/"+sb);
  workBook = WorkbookFactory.create(file); 
  Sheet sheet = workBook.getSheetAt(0);
  File tempFile = new File(path + fileNameSb.toString());
  FileOutputStream fos;
  fos = new FileOutputStream(tempFile);
  workBook.write(fos);
  fos.close();
  FilePath=path + fileNameSb.toString();
return FilePath;
}----creating a temporary file and storing it in a location


public void createExcel(String formatType)
{
Workbook workBook = null;
if((".xlsx").equalsIgnoreCase(formatType))
{
  workBook = new XSSFWorkbook();

}
else
{
  workBook = new HSSFWorkbook();    

}
String FilePath = getFilename();----retreiving the file and creating a workbook using the inputstream           
FileInputStream fileP= new FileInputStream(FilePath);

 workBook = WorkbookFactory.create(fileP);---- Exception here!!!!!
}

此外，我不会在excel生成过程中始终收到此错误。
