Question

我是Java新手。我想用石英创建一个作业调度程序。当我通过eclipse运行应用程序时，一切正常，但是我不知道如何在tomcat中部署它。在谷歌上到处都有，我发现只有一种创建调度程序的方法，而没有找到将其部署在tomcat中的方法。这可能是最基本的东西，但我不知道。我正在努力部署它。尽管我用石英制作它，但我并不仅仅坚持使用它。我对其他任何调度程序都开放，例如spring等。我需要帮助。下面是我编写的代码。

计划程序，主要方法是：

package com.pratibimb.jobscheduler.scheduler;
import org.quartz.CronScheduleBuilder;
import org.quartz.DateBuilder;
import org.quartz.JobBuilder;
import org.quartz.JobDetail;
import org.quartz.Scheduler;
import org.quartz.SchedulerException;
import org.quartz.SchedulerFactory;
import org.quartz.SimpleScheduleBuilder;
import org.quartz.Trigger;
import org.quartz.TriggerBuilder;

import com.pratibimb.jobscheduler.vaatsalyamjobs.ShowGenericMessages;

public class TaskScheduler {
    public static void main(String[] args) throws Exception {   
        TaskScheduler scheduler = new TaskScheduler();
        scheduler.fireJob();
    }
public void fireJob() throws SchedulerException, InterruptedException {
    SchedulerFactory schedFact = new org.quartz.impl.StdSchedulerFactory();
    Scheduler scheduler = schedFact.getScheduler();
    scheduler.start();

    // define the job and tie it to our HelloJob class
    JobBuilder jobBuilder = JobBuilder.newJob(ShowGenericMessages.class);

    JobDetail jobDetail = jobBuilder.withIdentity("myJob", "group1").build();


 // Fire at curent time + 1 min every day
    Trigger trigger = TriggerBuilder.newTrigger()
    .withIdentity("myTrigger", "group1")
    .startAt(DateBuilder.todayAt(22, 33, 20))
   // .withSchedule(CronScheduleBuilder.cronSchedule("0 " + (min + 1) + " " + hour + " * * ? *"))     
    .build();

    // Tell quartz to schedule the job using our trigger
    scheduler.scheduleJob(jobDetail, trigger);
    System.out.println("All triggers executed. Shutdown scheduler");
    //scheduler.shutdown();
  }
 }

class：ShowGenericMessages.java

package com.pratibimb.jobscheduler.vaatsalyamjobs;

import javax.ws.rs.client.Client;
import javax.ws.rs.client.ClientBuilder;
import javax.ws.rs.client.Entity;
import javax.ws.rs.client.Invocation;
import javax.ws.rs.client.WebTarget;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;

import org.glassfish.jersey.client.ClientConfig; 
import org.quartz.Job;
import org.quartz.JobDetail;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;

public class ShowGenericMessages implements Job {

     public void execute(JobExecutionContext jobContext) throws JobExecutionException {
    System.out.println("test 1");      

    }
}
