jsp swfupload 2.2 批量上传图片并将图片名保存到数据库

<%@ page contentType="text/html;charset=UTF-8"%>
<%
    double perMaxSize = 1.5;//单个文件允许的max大小
    String sizeUnit = "MB";//perMaxSize数据对应的单位
    String ext = "*.jpg;*.jpeg;*.gif";//允许上传的文件类型
    //文件上传提交的目标页面
    StringBuffer uploadUrl = new StringBuffer("http://");
    uploadUrl.append(request.getHeader("Host"));
    uploadUrl.append(request.getContextPath());
    uploadUrl.append("/admin/swfuploadexample/UploadFileExampleSubmit.jsp教程");
%>





css" rel="stylesheet" type="text/css" />

UploadFileExample.jsp对应的处理页面 --> UploadFileExampleSubmit.jsp 

(1)请确保已经看完我的另一篇文章（上传下载组件SmartUpload使用方法 http://stephen830.javaeye.com/admin/blogs/255010），先搞好这个才能开始下面的操作 
(2)写一个对应上传方法类，com.soft4j.bo.PhotoMgr.java，其中的方法就是文章下面提到的public static String fileUpload(SmartUpload su,PageContext pageContext) throws Exception {...}

<%@ page contentType="text/html;charset=UTF-8"%><%@ page import="com.soft4j.httpupload4j.SmartUpload"%><%@ page import="com.soft4j.bo.PhotoMgr"%><%  
    String pageErrorInfo = null;  
    SmartUpload su = null;  
    try{  
        su = new SmartUpload();  
        su.initialize(pageContext);  
        su.upload();  
        pageErrorInfo = PhotoMgr.fileUpload(su,pageContext);  
        if(pageErrorInfo==null){  
            out.print("successed");  
        }  
    }catch(Exception e){  
        pageErrorInfo = e.getMessage();  
    }finally{  
        su = null;  
        if(pageErrorInfo!=null){  
            out.print(pageErrorInfo);  
        }  
    }  
%> 

<%@ page contentType="text/html;charset=UTF-8"%><%@ page import="com.soft4j.httpupload4j.SmartUpload"%><%@ page import="com.soft4j.bo.PhotoMgr"%><%
    String pageErrorInfo = null;
    SmartUpload su = null;
    try{
        su = new SmartUpload();
        su.initialize(pageContext);
        su.upload();
        pageErrorInfo = PhotoMgr.fileUpload(su,pageContext);
        if(pageErrorInfo==null){
            out.print("successed");
        }
    }catch(Exception e){
        pageErrorInfo = e.getMessage();
    }finally{
        su = null;
        if(pageErrorInfo!=null){
            out.print(pageErrorInfo);
        }
    }
%>

第3步 准备后台的文件上传功能。也就是上面文件[UploadFileExampleSubmit.jsp]中用到的[PhotoMgr.fileUpload(su,pageContext)]方法

 Java代码
/** 
     * 文件上传方法. 
     * @param su 
     * @param pageContext 
     * @return 
     * @throws Exception 
     */ 
    public static String fileUpload(SmartUpload su,PageContext pageContext) throws Exception {  
        com.soft4j.httpupload4j.File suFile = null;  
        int fileCount = 0;  
        try {  
            //获取传递过来的参数  
            String userId = su.getRequest().getParameter("user_id");  
            String passId = su.getRequest().getParameter("pass_id");  
 
            String fileExt = "";  
            int fileSize = 0;  
            String AllowedExtensions = ",jpg,jpeg,gif,";//允许上传的文件类型  
            double maxFileSize = 1.5*1024;//单文件最大大小，单位KB  
            //校验文件类型和大小  
            for (int i=0; i                 suFile = su.getFiles().getFile(i);  
                if (suFile.isMissing())  
                    continue;  
                //校验文件大小  
                fileSize = suFile.getSize()/1024;//字节转换成KB  
                if(fileSize==0) fileSize=1;  
                if(maxFileSize       
                //校验文件类型  
                if (suFile.getFileExt() == null 
                        || "".equals(suFile.getFileExt())) {  
                    fileExt = ",,";  
                } else {  
                    fileExt = "," + suFile.getFileExt().toLowerCase() + ",";  
                }  
                if (!"".equals(AllowedExtensions)  
                        && AllowedExtensions.indexOf(fileExt) == -1) {  
                    throw new Exception("您上传的文件[" + suFile.getFileName()  
                            + "]的类型为系统禁止上传的文件类型，不能上传！");  
                }  
                fileCount++;  
            }
