Java 临时上传位置无效

The temporary upload location is not valid

提问by AlieneilA

I'm developing a web app with Java and Spring MVC (and hibernate to link to a MySQL database). I tried numerous ways to get my application to upload files. Unfortunately, I've encountered an error that says my temporary upload location is not valid. As a workaround, I've tried several locations like

我正在使用 Java 和 Spring MVC 开发一个 Web 应用程序（并且休眠以链接到 MySQL 数据库）。我尝试了多种方法来让我的应用程序上传文件。不幸的是，我遇到了一个错误，指出我的临时上传位置无效。作为一种解决方法，我尝试了几个位置，例如

• C:\Temp\
• C:\temp\
• C:/temp/
• /WEB-INF/tmp
• C:\Users\Default\AppData
• etc

• C:\温度\
• C:\临时\
• C:/温度/
• /WEB-INF/tmp
• C:\Users\Default\AppData
• 等等

Here is the error I'm getting

这是我得到的错误

Create a directory /tmp under -

在-下创建目录/tmp

C:\Users\take\eclipse\sts-bundle\pivotal-tc-server-developer-3.1.4.RELEASE\base-??instance\work\Catalina\localhost\ToolManagementSystem\WEB-INF

C:\Users\take\eclipse\sts-bundle\pivotal-tc-server-developer-3.1.4.RELEASE\base-??instance\work\Catalina\localhost\ToolManagementSystem\WEB-INF

So you have a directory -

所以你有一个目录 -

C:\Users\take\eclipse\sts-bundle\pivotal-tc-server-developer-3.1.4.RELEASE\base-??instance\work\Catalina\localhost\ToolManagementSystem\WEB-INF\tmp

C:\Users\take\eclipse\sts-bundle\pivotal-tc-server-developer-3.1.4.RELEASE\base-??instance\work\Catalina\localhost\ToolManagementSystem\WEB-INF\tmp

The other option is to change the temp directory through your tomcat configuration, or you can use spring boot which can configure this through an application property

另一种选择是通过您的 tomcat 配置更改临时目录，或者您可以使用 spring boot，它可以通过应用程序属性进行配置

Thanks

谢谢

change server.port value in application.properties file to another port,it will work.

将 application.properties 文件中的 server.port 值更改为另一个端口，它将起作用。

For one of our environment it was happen when external process clean up temporary directory. So we solved it just with restarting application.

对于我们的环境之一，当外部进程清理临时目录时会发生这种情况。所以我们只是通过重新启动应用程序来解决它。
