临时上传位置无效

Question

我正在使用 Java 和 Spring MVC（以及休眠以链接到 MySQL 数据库）开发一个 Web 应用程序。我尝试了多种方法让我的应用程序上传文件。很遗憾，我遇到了一个错误，提示 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
• 等

这是我遇到的错误

这是我的初始化程序和配置：

    servletContext.addListener(new ContextLoaderListener(ctx));

    ctx.setServletContext(servletContext);

    Dynamic servlet = servletContext.addServlet("dispatcher", new DispatcherServlet(ctx));
    servlet.addMapping("/");
    servlet.setLoadOnStartup(1);
    servlet.setMultipartConfig(getMultipartConfigElement());
}

Answer 1

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

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

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

谢谢

Answer 2

对于我们的一个环境，它是在外部进程清理临时目录时发生的。所以我们只需要重启应用就解决了。

Answer 3

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