求大神指点怎么回事？
下面是监听器：
package Listener1;
import javax.servlet.annotation.WebListener;
import javax.servlet.http.HttpSessionEvent;
import javax.servlet.http.HttpSessionListener;
@WebListener
public class HSL implements HttpSessionListener {
private int ub;
@Override
public void sessionCreated(HttpSessionEvent se) {
ub++;
se.getSession().getServletContext().setAttribute("ub", ub);
}
@Override
public void sessionDestroyed(HttpSessionEvent se) {
ub--;
se.getSession().getServletContext().setAttribute("ub", ub);
}
}
