使用SmartUpload上传图片

1.首先下载一个jspsmartupload.jar包

2.添加到WEB-INF/lib文件夹中

3.示例:

jsp界面:

<form action="${pageContext.request.contextPath }/servlet/sellProductServlet" method="post" ENCTYPE="multipart/form-data" >

 宝贝图片:<input type="file" name="filename"><br/><br/>
 <input type="submit" value="立刻发布">
 </form>

ENCTYPE="multipart/form-data";是必须使用的

sellProductServlet:

String url = null;
SmartUpload su = new SmartUpload();
//开始上传文件
try {
JspFactory fac=JspFactory.getDefaultFactory();
PageContext pageContext=fac.getPageContext(this, request,response, null, false, JspWriter.DEFAULT_BUFFER, true);
su.initialize(pageContext);
su.upload();
String pinstrution = su.getRequest().getParameter("pinstrution");			
File file = su.getFiles().getFile(0);
file.saveAs("/images/"+pcatagory+"/"+file.getFileName(),su.SAVE_VIRTUAL);//文件另存到tomcat部署的项目文件夹中,不是当前项目物理位置
//保存的是绝对路径
//file.saveAs("E:\\Workspaces\\MyEclipse 10\\SecondaryMarket\\WebRoot\\images\\"+pcatagory+"\\"+file.getFileName(),su.SAVE_PHYSICAL);
		    
url="./images/"+pcatagory+"/"+file.getFileName();
System.out.println(url);
		    
 String imagepath = url;//文件上传
System.out.println(imagepath);
ProductImple productImple = new ProductImple();
productImple.insert2Datebase(pcatagory, Float.parseFloat(pprice), pinstrution, pusername, imagepath, pname, Integer.parseInt(pnum));
response.sendRedirect("/SecondaryMarket/releaseSucc.jsp");
			
} catch (SmartUploadException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
路径问题在代码中我给了两种,一种是保存到tomcat下,推荐这样,这样便于移植,使用超级方便,想查看是否已经保存了,我是使用Myeclipse 10,你可以E:\Workspaces\MyEclipse 10\.metadata\.me_tcat\webapps\SecondaryMarket\images\Book去查看。
