我是結合在jspsmart.upload下使用的，這個是imgbean的代碼
package com.dcampus;
import java.awt.*;
import java.awt.event.*;
import java.io.*;
import java.awt.image.*;
import org.w3c.dom.*;
import com.sun.image.codec.jpeg.*;
import javax.imageio.*;
public class ImgBean_i{
public void ImgBean_i(){
}
public void ImgYin(String Imagename_biao,String ImgName){
try{
File _file = new File(ImgName);
Image src = ImageIO.read(_file);
int wideth=src.getWidth(null);
int height=src.getHeight(null);
BufferedImage image=new BufferedImage(wideth,height,BufferedImage.TYPE_INT_RGB);
Graphics g=image.createGraphics();
g.drawImage(src,0,0,wideth,height,null);
//水印文件
File _filebiao = new File(Imagename_biao);
Image src_biao = ImageIO.read(_filebiao);
int wideth_biao=src_biao.getWidth(null);
int height_biao=src_biao.getHeight(null);
g.drawImage(src_biao,wideth-110,height-110,wideth_biao,height_biao,null);
//水印文件在原圖片文件的位置，原圖片文件的右下角為wideth-0,height-0
?g.dispose();
FileOutputStream out=new FileOutputStream(ImgName);
JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(out);
encoder.encode(image);
out.close();
}
catch(Exception e){
System.out.println(e);
}
}
}
以下是修改過的smartupload代碼
<%@ page language="java" import="com.jspsmart.upload.*" import="java.util.*,java.text.*"%>
<%@ page contentType="text/html;charset=GBK" %>
<jsp:useBean id="mySmartUpload" scope="page" class="com.jspsmart.upload.SmartUpload"/>
<HTML><META http-equiv=Content-Type content="text/html; charset=gb2312">

?int count=0;??????
?String path=request.getRealPath("");
?mySmartUpload.initialize(pageContext);
?mySmartUpload.upload();
?connectToDatabase();
?for (int i=0;i<mySmartUpload.getFiles().getCount();i++){
??com.jspsmart.upload.File myFile = mySmartUpload.getFiles().getFile(i);
??if (!myFile.isMissing()) {
???int Size=myFile.getSize() ;
???String FileName=myFile.getFileName();
???String FileExt=myFile.getFileExt();
???String uploadtime=new java.text.SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format( java.util.Calendar.getInstance().getTime() );
???if(Size>=1000000) {
????out.println("文件超過1000K！"); //限制大小
???}else{
????if((FileExt.equals("jpg")) || (FileExt.equals("JPG")) || (FileExt.equals("gif")) || (FileExt.equals("GIF"))) {
?????java.util.Date date = new java.util.Date();
?????SimpleDateFormat formatter1 = new SimpleDateFormat("yyyyMMddHHmmss");
??????????? ????String name1=FileName.substring(0,FileName.indexOf("."));
??????????? ????String name2=FileName.substring(FileName.indexOf("."),FileName.length());
??????????? ????String newname=name1+formatter1.format(date)+name2;
?????//session.putValue("path1",newname);
?????myFile.saveAs("/photo/upfile/" + newname);
?????if(Integer.parseInt(sy)==1) {
??????com.pic.ImgBean_i bbb= new com.pic.ImgBean_i();
??????bbb.ImgYin(path+"/photo/images/shuiyin.gif",path+"/photo/upfile/" + newname);//這里是水印文件的來源地址，可修改成取得下拉菜單值的形式，這樣就可以實現打文字水印或者圖片水印了
?????}
?????stmt.executeUpdate("insert into img_photo (name,http,userid,classid,title,content,imgsize,format,num,primflag,posttime) values ()");
?????out.println(("<br><br><center>圖片上傳成功！<br>").toString());
????}else{
?????out.println("文件格式不對！");
????}
???}
???count ++;
??}
???else

???out.println("未找到上傳文件！\n");
??}

?disConnectToDatabase();
