session has already been invalidated

这个错误通常表示该 session 已经被无效化了，无法被再次使用。可能是由于 session 超时、被手动注销或者发生了一些错误导致的。如果您需要继续使用该 session，您可以尝试重新创建一个新的 session。如果该错误仍然存在，您可能需要检查您的代码，确认是否有对 session 进行无效化的操作。

session already invalidated

"sessionalreadyinvalidated" 是一个错误消息，意味着在尝试访问会话时会话已被无效化或销毁了。会话（session）是在网络应用程序中跨多个请求存储用户数据的一种方式。通常，当用户登录时，会创建一个新的会话，并将一个唯一的会话ID存储在用户的浏览器cookie中。这个会话ID可以用于在后续的请求中识别用户并访问他们存储在会话中的数据。如果会话被无效化或销毁，尝试访问会话数据时就会出现"sessionalreadyinvalidated"错误消息。这可能是由于超时、用户退出或其他原因导致的。为了解决这个问题，您需要确保在访问会话数据之前会话仍然处于有效状态。
很抱歉，会话已过期。这个错误通常表示您正在尝试使用已经无效的会话。可能是因为您在会话过期后仍然尝试访问它，或者您在使用会话之前已经显式地将其无效化。

要解决此问题，您可以尝试重新创建一个新的会话，并确保在会话过期后不再尝试访问旧的会话。您还应该确保在使用会话之前不要将其显式地无效化。

springsecurity sessiontimeout

Session timeout in Spring Security refers to the amount of time a user's session can remain active without any activity. When a user logs in to a web application, a session is created for that user. The session remains active until the user logs out, or until the session timeout period expires.

By default, Spring Security sets the session timeout to 30 minutes. However, this can be configured in the application's configuration file. To change the session timeout value, you need to set the `server.servlet.session.timeout` property in your `application.properties` file.

For example, to set the session timeout to 60 minutes, you can add the following line to your `application.properties` file:

server.servlet.session.timeout=60m

In addition to setting the session timeout, you can also configure Spring Security to handle session expiration. For example, you can redirect the user to a login page or display a custom message when the session expires. To do this, you need to configure the `session-management` element in your Spring Security configuration file.

<http>
    ...
    <session-management>
        <concurrency-control max-sessions="1" expired-url="/login?expired=true" />
    </session-management>
</http>

In the above example, the `max-sessions` attribute limits the user to only one session at a time. If the user tries to open a new session, the previous session will be invalidated. The `expired-url` attribute specifies the URL to redirect the user to when the session expires. In this case, the user will be redirected to the login page with a query parameter indicating that the session has expired.
