我正在尝试使用 ExecuteAndWait 拦截器上传多个文件。我已经完成了可以正常工作的文件上传部分，但是当我使用 execAndwait 时，出现以下错误

java.io.FileNotFoundException: C:\Users\hp\AppData\Roaming\NetBeans\8.0.2\config\GF_4.1\domain1\generated\jsp\FileUpload\upload_454f573a_3a8d_4e15_ba96_aa9cb6f4486f_00000002.tmp（系统找不到指定的文件）

行动

        setFd(fd);
       if(fd.fileupload(fb).equals("fileupload")){
           return "ok";


       }



        return "error";

    }


    @Override
    public void setServletRequest(HttpServletRequest hsr) {
        this.hsr=hsr;
    }

}

等待.jsp

<html>
    <head>
     <meta http-equiv="refresh" content="5"/>

        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>JSP Page</title>
    </head>
    <body>
        <h1>L O A D I N G......!!</h1>
    </body>
</html>

注意：我发现我的代码只接受一个文件上传文件或图像。
