@Ok("raw:jpg")

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

多写了return

我删了括号里的return,您看看我写的对吗?


@At("/html4") @Ok("raw:jpg") @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 new File( "../upload/images/" + uuid + "."+ Files.getSuffixName(file).toLowerCase()); //return "../upload/images/" + uuid + "."+ Files.getSuffixName(file).toLowerCase(); } public String webPath(String path) { return Mvcs.getServletContext().getRealPath("/upload/images/") + path; }

试了,报404

我的图片保存到E盘了,为什么报F盘文件找不到

怎么有2个点

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

那你得拼出一个合法的,存在的路径嘛

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

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

哦,你是提交. 那就改一下,变成

return new FileInputStream(...);

好了,谢谢啦

返回return new FileInputStream(...);的时候我前端页面怎么获取

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