是不是下面的代碼有什么問題？
InputStream fis = null;
BufferedOutputStream bos = null;
try {
String dpId = session.getAttribute("dp_id")==null?"":session.getAttribute("dp_id").toString();
String nameReport=request.getParameter("nameReport");
String workbook = request.getParameter("workbook");
if(workbook==null || "".equals(workbook)){
workbook = session.getAttribute("dp_id").toString();
}
String tempworkbook = workbook +"/";
tempworkbook = tempworkbook.replaceAll("主工作薄/",dpId+"/");
if(tempworkbook.endsWith("/")){
tempworkbook = tempworkbook.substring(0,tempworkbook.length()-1);
}
fis = request.getInputStream();
bos = new BufferedOutputStream(new FileOutputStream(new File(strAbsPath+"workbookspace\\"+tempworkbook+"\\"+nameReport+".cll")));
int b = fis.read();
while (b != -1) {
bos.write(b);
b = fis.read();
}
}catch (Exception e) {
e.printStackTrace();
}finally{
bos.flush();
bos.close();
fis.close();
bos = null;
fis = null;
}

原因：因為workbook路徑中包含了空格。
