取消部署应用程序时的触发功能

Question

在 Glassfish 中部署/取消部署/重新部署 JEE5 应用程序时，如何自动触发 Java 功能以停止 Quartz 调度程序作业。

Answer 1

实施ServletContextListener并挂上contextDestroyed().

基本示例：

public class Config implements ServletContextListener {

    public void contextInitialized(ServletContextEvent event) {
        // Write code here which should be executed on webapp startup.
    }

    public void contextDestroyed(ServletContextEvent event) {
        // Write code here which should be executed on webapp shutdown.
    }

}

并将其注册为<listener>in web.xml。

public class Config implements ServletContextListener {

    public void contextInitialized(ServletContextEvent event) {
        // Write code here which should be executed on webapp startup.
    }

    public void contextDestroyed(ServletContextEvent event) {
        // Write code here which should be executed on webapp shutdown.
    }

}
