文件上传是mulitpart

@wendal 前端 contentType就 设置的multipart/form-data

 config.headers = {
                'Authorization': sessionStorage.getItem('token'),
                'Content-Type': "multipart/form-data;boundary ="+ new Date().getTime()
            };

我现在把module层@AdaptBy(type = UploadAdaptor.class, ) 换成了WhaleAdaptor.class 但是 前端只能传一个文件 传多个文件过来 我后台直接收到不 数据

@At
	 @AdaptBy(type = WhaleAdaptor.class, args = { "ioc:myPicUpload" })
	public Object saves(@Param("img")TempFile [] imgs,HttpServletRequest req,@Param("uid") String uid,
			@Param("tid")String tid,@Param("tit")String tit,@Param("cons")String cons,
			@Param("mes")String mes,@Param("tale")int tale,@Param("cluid")String cluid
			){
		//支线任务添加
		//Users users =(Users)session.getAttribute("users");
		Decode d =new Decode();
		TShoufa t =new TShoufa();
		  //t.setTask_zid(d.getzhongwen(tid));//主任务id
			t.setTask_tit(d.getzhongwen(tit));//标题
			t.setTask_cons(d.getzhongwen(cons));//内容
			t.setTask_level(tale);//等级
			t.setTask_staruid(uid);//发起人id
			t.setTask_cluid(d.getzhongwen(cluid));//处理人id（可多人）
			t.setTask_dclrid(d.getzhongwen(cluid));//主标添加待处理人（辅助查询）
			t.setTask_sjclid(uid);
			String[] user =d.getzhongwen(cluid).split(",");
			//	System.out.println(users);
			List<String> userssss =Arrays.asList(user);	
			new TuiSong(userssss, d.getzhongwen(cluid)).start();
			
			tTaskService.saves(req, imgs, t);
			return true;

@wendal 这是前端 浏览器 显示传递的数据 img的类型 如果直接是一个文件 可以直接上传 如果是个文件数组 我后台接收 全是空数据

studyname: 
1111
studycontent: 
1111
studytype: 
4024335320D84D198D6FC3E29A552E62
img: 
[object File],[object File]
uid: 
BE65BC3D530A4D41AAD749DF5ED65F04

那是你前端代码的锅了

@wendal 为啥 img 上传多文件 会显示 [object File]

@wendal 我让前端 再研究研究吧 感谢！！
