现在上传成功是返回一个图片路径，我想直接返回上传的图片到页面怎么改？

@At("/html4")
	@AdaptBy(type=UploadAdaptor.class, args="ioc:upload")
	//上传
	public Object html4(@Param("f")TempFile tmpFile, AdaptorErrorContext errCtx) {
		if (errCtx != null) {
			log.info(errCtx.getAdaptorErr());
			return false;
		}
		if (tmpFile == null || tmpFile.getFile().length() < 1024) {
			return false;
		}
		
		
		log.debug(tmpFile.getMeta().getFileLocalName());
		
		
		
		File file = tmpFile.getFile();
		String uuid = UUID.randomUUID().toString().replaceAll("-", "");
		System.out.println(Files.getSuffixName(file).toLowerCase());
		System.out.println(webPath(uuid));
		String dest = webPath(uuid) + "." + Files.getSuffixName(file).toLowerCase();
		System.out.println();
		String smallPath = webPath(uuid)  + Files.getSuffixName(file).toLowerCase();
		try {
			Images.zoomScale(file, new File(smallPath), 128, 128, Color.BLACK);
			file.renameTo(new File(dest));
		} catch (Throwable e) {
			log.info(e);
			return false;
		}
		
		
		return "../upload/images/" + uuid + "."+ Files.getSuffixName(file).toLowerCase();
	}
	
	public String webPath(String path) {
		return Mvcs.getServletContext().getRealPath("/upload/images/") + path;
	}

@Ok("raw:jpg")

return new File(return "../upload/images/" + uuid + "."+ Files.getSuffixName(file).toLowerCase());

我删了括号里的return，您看看我写的对吗？

怎么有2个点

qq_ce1cdaf7 8楼•2681天前

return new File( "../upload/images/" + uuid + "."+ Files.getSuffixName(file).toLowerCase());
您指的是这两个点吗，这两个点不用也行，我删了也还是报错

wendal

9楼•2681天前

那你得拼出一个合法的,存在的路径嘛

wendal

10楼•2681天前

return new File(Mvcs.getServletContext().getRealPath("/upload/images/") + uuid + "."+ Files.getSuffixName(file).toLowerCase()));

qq_ce1cdaf7 11楼•2681天前

点击提交之后图片直接被下载下来了在页面不能显示而且页面没有跳转该怎么样才能直接显示在页面上

wendal

12楼•2681天前

哦,你是提交. 那就改一下,变成

return new FileInputStream(...);

参照nutzwk的
上传后返回
return Result.success("上传成功", f + "_s" + suffix);
