今天用了一下webuploader插件，发现特别好用，但是在我自己写功能的时候，文件明明已经上传上去了，但是还是提示失败，我用的springMVC，然后发现提示我找不到对应的controller路径，我路径是没有问题的，然后并不执行uploadSuccess方法，最后发现在
showError = function(code) {
alert("code="+code);
switch( code ) {
case 'exceed_size':
text = '文件大小超出';
break;
case 'interrupt':
text = '上传暂停';
break;
default:
text = '上传失败，请重试';
break;
}
里面code是http，这是什么问题造成的呢？哪位大神可以帮忙
补充一下，uploadError返回的是undefined，为什么没有把值传过来？
自己来回答一下吧，今天一天就研究这个东西了，我用的springMVC，本来是很简单的事情，搞来搞去现在终于摸清楚了一点点，uploadError和uploadSuccess方法接受的类型是json的，用String的就会出现undefined，把后台返回值改成json的就好了，另外code返回http这个问题，随着也解决了，下面贴上我的代码
这个是upload.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

这个是后台上传的Controller

@Controller
public class UploadController extends com.jfinal.core.Controller {
@RequestMapping("index")
public void index(){
render("upload.jsp");
}
@RequestMapping(value="upload.action",method=RequestMethod.POST)
@ResponseBody
public String imageUpload(HttpServletRequest request,HttpServletResponse response)throws Exception{//返回文件存储相对路径
CommonsMultipartResolver multipartResolver=new CommonsMultipartResolver(
request.getSession().getServletContext());
//检查form中是否有enctype="multipart/form-data"
String path = "";
String status = "";
System.out.println("----------------------------------------------");
JSONObject json = new JSONObject();
if(multipartResolver.isMultipart(request))
{
String newFileName = "";
//将request变成多部分request
MultipartHttpServletRequest multiRequest=(MultipartHttpServletRequest)request;
//获取multiRequest 中所有的文件名
Iterator iter=multiRequest.getFileNames();
SimpleDateFormat df = new SimpleDateFormat("yyyyMMddHHmmss");//设置日期格式
while(iter.hasNext())
{
//一次遍历所有文件
MultipartFile file=multiRequest.getFile(iter.next().toString());
if(file!=null)
{
String fullFileName = file.getOriginalFilename();
String extendsFileName = fullFileName.substring(fullFileName.lastIndexOf(".")+1);
String fileName = fullFileName.substring(0, fullFileName.lastIndexOf("."));
newFileName = fileName+String.valueOf(df.format(new Date()))+"."+extendsFileName;
path = "C:/MyeclipseWorkspace/TimeSeaUpload/"+newFileName;
//上传
file.transferTo(new File(path));
}
}
json.put("status", "OK");
System.out.println(json.toString());
return json.toString();
}else{
json.put("status", "NO");
return json.toString();
}
}
}
