在会话超时时设置Liferay Hook

问题描述

我想编写一个Java中的Hook，如果Liferay 5.2.3 Portal的会话超时则会执行。

I want to write a Hook in Java that is executed if the session of my Liferay 5.2.3 Portal times out.

我设法编写一个Hook，只要用户点击logout链接，就会执行Hook，并在 liferay-hook.xml中使用以下设置：

I managed to write a Hook that is executed whenever the user clicks the logout link with the following setup in the liferay-hook.xml:

<hook>
    <event>
        <event-class>com.extensions.hooks.LogoutHook</event-class>
        <event-type>logout.events.pre</event-type>
    </event>
</hook>

然而，如果会话超时，则不会调用Logout Hook，但我需要执行相同的操作超时的方法。我没有找到会话超时的事件类型。

However the Logout Hook does not get called if the session times out, but I need to execute the same method on a timeout. I did not find an event-type for a session timeout.

当会话超时并且识别用户ID时，是否有办法执行Java方法结束会话？

Is there a way to execute a Java-Method when the session times out and identify the User-ID of the ended session?

推荐答案

有一个事件将在会话到期/ TimeOut 事件时触发用户会话，

There is an event which will be triggered upon Session Expiry/TimeOut event of User Session,

# Servlet session destroy event
servlet.session.destroy.events = com.extensions.hooks.CustomPreSessionExpireAction

您可以在添加该属性的liferay-hook.xml 或 portal.properties [写在钩子中]或 portal-ext.properties 。

You can either add this property in liferay-hook.xml or portal.properties [Written in Hook] or portal-ext.properties.

和可以用作，

public class CustomPreSessionExpireAction extends SessionAction {

    @Override
    public void run(HttpSession session) throws ActionException {
        //Code
    }
}

但是，我们可以这里只使用 HttpSession 。所以，你需要找出在这里获得 userId 的方法。

However, We can only use HttpSession here. So, you need to figure out the way to get userId here.
