文件上传，改成自定义名称

请问一下，我想实现一下别人上传文件，改成我自己定义的文件名，同时没有文件路径自动生成，谢谢
package com.bug.servlet;
import java.io.IOException;
import java.util.Enumeration;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import com.oreilly.servlet.MultipartRequest;
import com.oreilly.servlet.multipart.DefaultFileRenamePolicy;

@SuppressWarnings("serial")
public class MultipartTestServlet2 extends HttpServlet {
public MultipartTestServlet2() {
super();
}
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
//request.setCharacterEncoding("gbk"); 不起作用
System.out.println("start ");
MultipartRequest multi = new MultipartRequest(request, "c:/tmp/", 2*1024*1024, "gbk", new
DefaultFileRenamePolicy());
System.out.println("start ");
Enumeration filesName = multi.getFileNames();
Enumeration paramsName = multi.getParameterNames();
while(paramsName.hasMoreElements()){
String paramName = (String) paramsName.nextElement();
System.out.println(multi.getParameter(paramName));
}
while(filesName.hasMoreElements()){
String fileName = (String) filesName.nextElement();
System.out.println(multi.getFilesystemName(fileName) + " " +
multi.getOriginalFileName(fileName) + " " +
multi.getContentType(fileName) + " ");
if(multi.getFilesystemName(fileName)!=null && !multi.getFilesystemName(fileName).equals(""))
System.out.println(multi.getFile(fileName).toURI());
}
}

}

解决方案

很简单啊，直接按照自己的命名规则命名就可以了，路径可以声明常量，数据库只存自己的文件名，取得时候拼接
