Java 当我上传一个现有的图像时，我得到了500个错误

我无法使用servlet将图像上载到我的数据库，我得到以下错误

HTTP Status 500 - troubleshoot.png (No such file or directory)

我的web.xml文件包含以下内容：

<context-param>
      <param-name>tempfile.dir</param-name>
      <param-value>tmpfiles</param-value>
</context-param>

如果这是您的实际代码，那么您在输入中有2个type属性field@singhakash修正了，同样的错误。你试过上传其他的吗image@divinediu您是否已解决问题，发布表单代码？仍然无法上载图像

<context-param>
      <param-name>tempfile.dir</param-name>
      <param-value>tmpfiles</param-value>
</context-param>

 st.setPic(new FileInputStream(new File(request.getParameter("photo"))));
