attachmentSimple在页面上测试是可以获取到文件真实的名字,但是在真机缺是获取到乱码,例如image%3A26872这种

请问你是怎么获取的？？app乱码问题，需要注意的就是加密和非加密的情况别冲突！！
如果你想在attachmentSimple 上传图片后显示文件名字，可以参考
http://docs.wex5.com/wex5-ui-question-list-2151

或者截图，把你的情况再说明白一些！

如果你想在attachmen ...

主要是我上传的时候我提交代码是
var cuisineData = this.comp('cuisineDetailData');
var row = cuisineData.getCurrentRow();
var jsonList1 = eval("(" +row.val('fImage')+")");
var ownerID = row.getID();
var str="$UI2/tsj/data/attachmentSimple";
var realFileName = jsonList1[0]["realFileName"];
var fImage = str+"/"+ownerID+"/"+realFileName;
alert(fImage);
cuisineData.setValue("fImage",fImage,row);
alert(fImage);
this.comp('windowReceiver').windowEnsure(row);
是弹出他的路径和图片名称的,但是获取到就这个image%3A26872
楼下附上java代码

java代码是自己实现的吗？？
参考/Baas/justep/SimpleFileStore.java 写的吗？？

默认情况获取上传图片URL代码！可以参考

参考改的,也就改了private static void storeFile(HttpServletRequest request,
HttpServletResponse response) throws Exception {
HashMap<String,String> params = new HashMap<String,String>();
List<FileItem> items =  parseMultipartRequest(request);
Iterator<FileItem> iter = items.iterator();
FileItem fileItem = null;
while (iter.hasNext()) {
      FileItem item = iter.next();
      if (item.isFormField()) {
        String name = item.getFieldName();
            String value = item.getString();
         params.put(name, value);
      } else {
        /*String fieldName = item.getFieldName();
         String fileName = item.getName();
         String contentType = item.getContentType();
         boolean isInMemory = item.isInMemory();
         long sizeInBytes = item.getSize();*/
        fileItem = item;
      }
}
if(fileItem != null){
String storePath = docStorePath + File.separator + params.get("ownerID");
         File storeDir = new File(storePath);
         if(!(storeDir.exists() && storeDir.isDirectory())){
            storeDir.mkdirs();
         }
         File toStoreFile = new File(storePath + File.separator + params.get("storeFileName"));
         fileItem.write(toStoreFile);
}

}
这个方法最后保存的是真实的名字加后缀,关键是我用手机端的话,代码到这就不行了,网页端可以

String ownerID = URLEncoder.encode(request.getParameter("ownerID"), "utf-8");

修改java代码字符串编码处理一下试试吧！

本来id列就不应该是汉字的！

你把所有获取ownerID 的地方都转码一次试试吧
比如 storeFile 方法中

调用 mkdirs 方法的地方尤其注意！这个就是创建文件夹的方法！
