Question

我尝试使用ExecuteAndWait Interceptor上传多个文件。我已经完成了文件上传部分工作正常，但是当我使用execAndwait时，我收到以下错误

java.io.FileNotFoundException： C：\ Users \用户马力\应用程序数据\漫游\的NetBeans \ 8.0.2 \配置\ GF_4.1 \ domain1的\生成\ JSP \文件上传\ upload_454f573a_3a8d_4e15_ba96_aa9cb6f4486f_00000002.tmp （系统找不到指定的文件）

struts.xml中

wait.jsp

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

        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

    </head>
    <body>
        <h1>L O A D I N G......!!</h1>
    </body>

注意：我发现我的代码只接受一个文件上传文件或图片。

使用struts2中的execandwait拦截器上传多个文件
