<script type="text/javascript" src="uploadify/swfobject.js"></script>
<script type="text/javascript" src="uploadify/jquery.uploadify.js"></script>

$(document).ready(function(){
    $("#mediaID01").uploadify({
         'swf' : 'uploadify/uploadify.swf',
        'uploader' : '../WxController/saveMediaInServer',//后台处理的请求

        'fileDesc' : 'Image Files (*.jpg;*.jpeg;*.gif;*.png)',

后台代码:

        MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) request;
        List<String> responseStr= new ArrayList<String>();
        Map<String, MultipartFile> fileMap = multipartRequest.getFileMap();   
        // 创建文件夹  
        Map<String, Object> type = JSON.parseObject(formData, new TypeReference<Map<String, Object>>(){});
        Date now=new Date();
        SimpleDateFormat dateFormat = new SimpleDateFormat("yyyyMMdd");
        String filePath = "/upload/"+type.get("typeName")+"/"+dateFormat.format(now);
        String path=request.getSession().getServletContext().getRealPath(filePath);
        File file = new File(path);    
        if (!file.exists()) {    
            file.mkdirs();
        }
        for (Map.Entry<String, MultipartFile> entity : fileMap.entrySet()) {  
            // 上传文件   
            MultipartFile mf = entity.getValue();
            String filename=String.valueOf(System.currentTimeMillis()) + (int)(Math.random()*1000000);
            File uploadFile = new File(path + filename);
            try {  
                FileUtils.copyInputStreamToFile(multipartFile.getInputStream(),file);;  
                responseStr.add("上传成功");  
            } catch (IOException e) {  
                responseStr.add("上传失败");   
                e.printStackTrace();  
            }         
        }
        return responseStr;

 

 查看了好多遍代码,不知道哪儿出了问题,之前已经提问过一次,还是没有解决问题。高分跪求大神指导,感激不尽啊~

不知道怎么改哎/尴尬

shayusuf | 园豆:31 (初学一级) | 2015-11-30 15:54

@shayusuf: uploadify/uploadify.swf 找到你的这个文件啊。右键选中  属性-》生成-》改为嵌入的资源试下!这样就能编译到DLL里,好像是这样!试试吧!

@贫民窟大侠: 大侠,能加你的qq么

shayusuf | 园豆:31 (初学一级) | 2015-11-30 16:36

@贫民窟大侠: 编译之后还是报相同的错误~

shayusuf | 园豆:31 (初学一级) | 2015-11-30 17:08

@shayusuf: 你编译之后传了这个dll了吗?

贫民窟大侠 | 园豆:4270 (老鸟四级) | 2015-11-30 17:34

@贫民窟大侠: 谷歌F12。network,查看上传文件时候的请求。看请求的信息!你这是编译错误还是运行时错误?

贫民窟大侠 | 园豆:4270 (老鸟四级) | 2015-11-30 17:35

@贫民窟大侠: 传了,运行时错误吧~

@shayusuf: 刚查了一下,org.apache.catalina.connector.RequestFacade cannot be cast to org.springframework.web.multipart.MultipartHttpServletRequest 是这个问题,需要在xml文件中添加配置  请问应该怎么添加

@shayusuf: 嵌套异常,捕获不到你添加的资源  'uploadify/uploadify.swf',下面有人说了。。

这样做就应该好了
