部署的Spring App在首次登录时未被路由到正确的URL

Question

我向Heroku部署了一个Spring App。我正在使用Spring Security登录和注册。我的问题是，对于新用户，当他们最初登录时，会将他们带到基本URL（Heroku为我的网站提供的URL）。我的所有主要html文件都在名为＆＃34; cheese＆＃34;的文件夹中。问题是它引导我到主URL（而不是＆＃34; / cheese / account＆＃34;，这是我指示它在我的SecurityConfig中路由的地方），我得到一个白标签错误。

这只是第一次发生。当他们再次登录时，会将他们带到正确的URL，即＆＃34; / cheese / account＆＃34;。此外，偶尔，我会点击heroku为我的网站提供的基本网址，它只给我一个网址，并没有指示我去＆＃34; / cheese / login＆＃34;。如果我尝试从隐身窗口访问该网址，就会发生这种情况。

在本地运行它时根本没有这个问题。这是相关的代码......如果您还需要任何东西，请告诉我。
