commons-fileupload的一个exception的问题
javac编译时，提示如下：

Test.java:40: unreported exception org.apache.commons.fileupload.FileUploadExcep
tion; must be caught or declared to be thrown
  List items = sfu.parseRequest(req);
  ^
1 error


代码如下：

package mytest;

import java.io.IOException;
import java.io.FileOutputStream;
import java.util.List;
import java.util.Iterator;
import java.util.HashMap;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
//import javax.servlet.http.HttpSession;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.commons.fileupload.FileUploadException;
import org.apache.commons.fileupload.FileItem;
import org.apache.commons.fileupload.FileItemFactory;
import org.apache.commons.fileupload.disk.DiskFileItemFactory;
import org.apache.commons.fileupload.servlet.ServletFileUpload;

public class Test extends HttpServlet {
  static final long serialVersionUID = 1L;

  private String fileExt(String fileName)
  {
  return fileName.substring(fileName.lastIndexOf(".") + 1);
  }

  public void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException
  {
  req.setCharacterEncoding("UTF-8");

  /*
  HttpSession sess = reg.getSession();
  String uid = (String)sess.getAttribute("uid");
  */

  FileItemFactory fif = new DiskFileItemFactory();
  ServletFileUpload sfu = new ServletFileUpload(fif);
  List items = sfu.parseRequest(req); //here is line 40
  Iterator iter = items.iterator();
  FileItem item = null;
  HashMap<String, String> data = new HashMap<String, String>();
  while(iter.hasNext()) {
  item = (FileItem)iter.next();
  if(item.isFormField())
  data.put(item.getFieldName(), item.getString("UTF-8"));
  else {
  FileOutputStream fos = new FileOutputStream("C:\\Users\\my\\9." + fileExt(item.getName()));
  fos.write(item.get());
  fos.flush();
  fos.close();
  }
  }

  data.clear();
  }
}

我没有try-catch。我的疑问是，为什么会有exception？怎么解决？
谢谢大家！

------解决方案--------------------
你写的有问题，当然报异常了，你把完整的异常信息贴出来吧。。。。。

把异常信息贴出来吧！！！！！
------解决方案--------------------
List items = sfu.parseRequest(req);
必须捕获异常。

你捕获下异常应该就没问题了
------解决方案--------------------
List items=null;
try {
items = sfu.parseRequest(req);
} catch (FileUploadException e) {
// TODO 这里根据自己的需求进行处理，可以为空（不建议）
e.printStackTrace();

}


不建议采用 S
