Answer 1

对变量name没有处理好，name还带着完整的：“C:\Documents and Settings\Administrator\桌面\图片\亮度\0.bmp”
导致最后组装出来的文件路径是错误的。
修改下：
  name = name.substring(name.lastIndexOf("\\") + 1);

Answer 2

public String upload(){
HttpServletRequest request = ServletActionContext.getRequest();
DiskFileItemFactory factory = new DiskFileItemFactory();
ServletFileUpload upload = new ServletFileUpload(factory);
String rootpath = ServletActionContext.getServletContext().getRealPath("/");
try {
List item = upload.parseRequest(request);
Iterator it = item.iterator();
while(it.hasNext()){
FileItem fileItem = (FileItem)it.next();
if(!fileItem.isFormField()){
if(fileItem.getName() != null && !"".equals(fileItem.getName())){
System.out.println("原文件名："+fileItem.getName());
System.out.println(fileItem.getContentType());
System.out.println(fileItem.getFieldName());
File file = new File(rootpath+"/img"+fileItem.getName()+".jpg");
fileItem.write(file);
this.printMessage(this.OPERATE_SUCCESS);
}
}
}
}  catch (Exception e) {
e.printStackTrace();
}
return null;
}你参照着试试看
