我正在尝试遵循“ Quartz Scheduling框架工作”一书“在Web应用程序中初始化Quartz”示例中提到的步骤。这是程序https://gist.github.com/5777d9f27c700e716a5a的链接。但是该示例在Struts1框架上。

我们的是带有Hibernate 3.5 ORM的struts2框架。我应如何在Struts2上配置确切步骤。任何帮助,将不胜感激。

但是,如果我在contextInitialized()方法中编写代码,则会得到异常“ java.lang.RuntimeException:java.io.FileNotFoundException:src / hibernate.cfg.xml(无此类文件或目录)”

Xml config = new Xml("src/hibernate.cfg.xml", "hibernate-configuration");
Properties prop = new Properties();
prop.setProperty("org.quartz.dataSource.tasksDataStore.driver", config.child("session-
                                      factory").children("property").get(1).content());
prop.setProperty("org.quartz.dataSource.tasksDataStore.URL", config.child("session-
                                      factory").children("property").get(2).content());
prop.setProperty("org.quartz.dataSource.tasksDataStore.user", config.child("session-
                                      factory").children("property").get(3).content());
prop.setProperty("org.quartz.dataSource.tasksDataStore.password", config.child("session-
                                      factory").children("property").get(4).content());
prop.setProperty("org.quartz.dataSource.tasksDataStore.maxConnections", "20");

SchedulerFactory sf = new StdSchedulerFactory(prop);
Scheduler sched = sf.getScheduler();

最佳答案

要在容器加载时初始化调度程序,可以执行此操作。

import javax.servlet.ServletContext;
import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;

import org.quartz.SchedulerException;
import org.quartz.impl.StdSchedulerFactory;

public class QuartzServletContextListener implements ServletContextListener
{
    public static final String QUARTZ_FACTORY_KEY = "org.quartz.impl.StdSchedulerFactory.KEY";
    private StdSchedulerFactory factory = null;

    /**
     * Called when the container is shutting down.
     */
    public void contextDestroyed(ServletContextEvent sce)
    {
        try
        {
            factory.getDefaultScheduler().shutdown();
        } catch (SchedulerException ex)
        {
        }

    }

    /**
     * Called when the container is first started.
     */
    public void contextInitialized(ServletContextEvent sce)
    {
        ServletContext ctx = sce.getServletContext();
        try
        {
            factory = new StdSchedulerFactory();

            // Start the scheduler now
            factory.getScheduler().start();
            ctx.setAttribute(QUARTZ_FACTORY_KEY, factory);

        } catch (Exception ex)
        {
        }
    }
}


在您的web.xml中,添加

<listener>
    <description>A Listener Class to initialize Quartz Scheduler</description>
    <listener-class>full_package_path.QuartzServletContextListener</listener-class>
</listener>


当容器加载时,这基本上会创建调度程序。然后,您可以使用我以前的文章从StdSchedulerFactory检索StdSchedulerFactory
让我知道是否有问题。
