@AdaptBy(type = UploadAdaptor.class, args = { "${app.root}/WEB-INF/tmp", "8192", "utf-8" })
	@At("/verifyExcel")
	@Ok("raw")
	public void verifyExcel(@Param("file") TempFile tmpFile){
		List<VoucherEntity> list;
		try {
			list = FileUtil.importExcel(tmpFile.getInputStream(), 0, 2, VoucherEntity.class);
			System.out.println(list.size());
		} catch (IOException e) {
			e.printStackTrace();
		}

这个方法FileUtil.importExcel(tmpFile.getInputStream(), 0, 2, VoucherEntity.class);在本地测试传入一个文件是没有错的。这个是文件没有完全上传就解析的原因吗？但是貌似很难判断文件上传完成把。

上传完成才会进入口方法

怎么判断上传完成呢？

判断? 判断啥?

上传完成才进入入口方法 我怎么判断上传完成呢？

跑你的代码的时候, 是已经上传完成的

是自己傻逼了。代码有点问题。
