开发一个签到系统,需要记录登录、退出的时间等信息, 如果用户不点击退出直接关闭浏览器, 想使用HttpSessionListener监听sessionDestroyed来记录用户退出时间 .配置了监听器, 没起作用, 求大神指点. 当前web.xml配置:

<?xml version="1.0" encoding="UTF-8"?>
<web-app 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns="http://java.sun.com/xml/ns/javaee"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    id="WebApp_ID" version="2.5">
    <listener>
        <listener-class>listener.MySessionListener</listener-class>
    </listener>
    <filter>
        <filter-name>jfinal</filter-name>
        <filter-class>com.jfinal.core.JFinalFilter</filter-class>
        <init-param>
            <param-name>configClass</param-name>
            <param-value>config.SystemConfig</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>jfinal</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

</web-app>

MySessionListener.kt

class MySessionListener:HttpSessionListener {
    override fun sessionDestroyed(p0: HttpSessionEvent?) {
        val session: HttpSession? = p0?.session
        val user: Staff? = session?.getAttribute("user") as Staff?
        if (user!=null){
            val ip: String? = session?.getAttribute("ip") as String?
            var loginRecord: LoginRecord = LoginRecord()
            loginRecord.staffId = user.id
            loginRecord.did = "out"
            loginRecord.ip = ip
            loginRecord.save()
        }
        println("session was destroyed")
    }

    override fun sessionCreated(p0: HttpSessionEvent?) {
        println("session was create")
    }
}
