webwork2如何系统启动的时候就执行一个bean进行初始化呢？在那里配置呢

Question

webwork是用一个filter来配置的，系统启动的时候，这个filter都没执行呢，所以你的要求满足不了只能手工配置listener等，或者配置个servlet，然后把load-on-startup设置成1

Answer 2

在web.xml写istener吧
<listener>
<listener-class>com.ogss.ss.HttpContext</listener-class>
</listener>
public class HttpContext implements ServletContextListener {
    public void contextInitialized(ServletContextEvent arg){}....
    public void contextDestroyed(ServletContextEvent arg) {}....
}

java.lang.ClassNotFoundException: com.poolpop.StatisticsContextListener 你缺少包

Answer 5

会不会是你的类的路径在web.xml中配置的不对？
