JSp页面:
<%@page contentType= "text/html;charset=GBK "%>
<%@ taglib uri= "http://jakarta.apache.org/struts/tags-logic "
prefix= "logic "%>
<%@ taglib uri= "http://jakarta.apache.org/struts/tags-html "
prefix= "html "%>
<%@ taglib uri= "http://jakarta.apache.org/struts/tags-bean "
prefix= "bean "%>
<html>
<script type= "text/javascript ">
function v(){
document.myform.img.src=document.myform.pic.value;
}
</script>
<body>
<form action= "photo.do?p=main " method= "POST " enctype= "multipart/form-data " name= "myform ">
<input type= "file " name= "pic " onchange= "v() " >
<img name= "img " src= " " >
<img name= "abc " src= "photo.do?p=view ">
<input type= "submit " value= "going "/>
</form>
</body>
</html>
Action:
PhotoForm tform = (PhotoForm) form;
FormFile file = tform.getPic();
String name = "ruby ";
if (file.getFileSize() > 10000) {
}
// 获取文件名
String filename = file.getFileName();
int index = filename.lastIndexOf( ". ");
filename = filename.substring(index);
// 设置图片文件临时存放的路径
String path = "D:/ " + name + filename;
try {
// 读取文件中的数据，获取二进制的数据流
InputStream stream = file.getInputStream();
// 把数据写到指定路径
OutputStream bos = new FileOutputStream(path);
int bytesRead = 0;
byte[] buffer = new byte[8192];
while ((bytesRead = stream.read(buffer, 0, 8192)) != -1) {
bos.write(buffer, 0, bytesRead);
}
bos.flush();
bos.close();
stream.close();
} catch (Exception fe) {
}
file.destroy();
然后就是得到文件路径的名称插入到数据库中.

有上传下载包smartupload
你可以把图片上传到一个文件夹，在数据库的表中，保留这个图片在网站上的相对路径，每次读相对地址，就可以把图片读出来。很方便的，我很早就已经实现了。

private void uploadPic(){
StringBuffer sb=new StringBuffer();
try{
Upload uploader = new Upload(session.getServletContext(), request,JPath.getAppPath()+ "uploadfile/ ", "GBK ", 500000);
uploader.setSaveInTempFile(false);
UploadMsg upMsg = uploader.save();
/*
* 如果上传成功，做相应处理
*/
if (upMsg.isSuccessful)
{
Map <String,String> paras=uploader.getOtherParameters();
String title=paras.get( "title ");
String introduce =paras.get( "introduce ");
String filename=((UploadedFile) uploader.getUploadedFiles().get(0)).getFileName_Saved();
String smallpic =filename;
Stringbigpic =((UploadedFile) uploader.getUploadedFiles().get(0)).getAbsoluteFileName_Saved();
try {
dao = factory.createDAO();
WProduct vo = new WProduct();
dao.initAutoincreasingPrimaryKey( "w_product ");
vo.setMsgid(new Integer(dao.genAutoincreasingPrimaryKey( "w_product ").intValue()));
vo.setTitle(title);
vo.setIntroduce(introduce);
vo.setSmallpic(smallpic);
vo.setBigpic(bigpic);
dao.insert(vo);
dao.close();
}catch (Exception e) {
e.printStackTrace();
jlog.Error( " " + e);
}
this.resultString = " <script> alert( '上传成功 ');history.back(); </script> ";
}
else
{
//上传失败
}
}catch(Exception e){
e.printStackTrace();
}
}
