spring实现对quartz的动态增删改及启动、停止操作

通过spring的这里用到spring的 org.springframework.scheduling.quartz.SchedulerFactoryBean 可以轻松实现对quartz中定时任务的管理。直接上代码：

package com.eversec.mastersp.business.action;

import com.wordnik.swagger.annotations.ApiOperation;
import org.quartz.*;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.scheduling.quartz.SchedulerFactoryBean;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
@RequestMapping("/quartz")
public class QuartzManagerAction {

    @Autowired
    private SchedulerFactoryBean schedulerFactory;

    /**
     * @param jobName          任务名
     * @param jobGroupName     任务组名
     * @param triggerName      触发器名
     * @param triggerGroupName 触发器组名
     * @param jobClass         任务
     * @param cron             时间设置，参考quartz说明文档
     * @Description: 添加一个定时任务
     */
    @SuppressWarnings({"unchecked", "rawtypes"})
    @ApiOperation(value = "添加一个定时任务")
    @RequestMapping("/addJob")
    public void addJob(String jobName, String jobGroupName,
                       String triggerName, String triggerGroupName, Class jobClass, String cron) {
        try {
            Scheduler sched = schedulerFactory.getScheduler();
            // 任务名，任务组，任务执行类
            JobDetail jobDetail = JobBuilder.newJob(jobClass).withIdentity(jobName, jobGroupName).build();

            // 触发器
            TriggerBuilder triggerBuilder = TriggerBuilder.newTrigger();
            // 触发器名,触发器组
            triggerBuilder.withIdentity(triggerName, triggerGroupName);
            triggerBuilder.startNow();
            // 触发器时间设定
            triggerBuilder.withSchedule(CronScheduleBuilder.cronSchedule(cron));
            // 创建Trigger对象
            CronTrigger trigger = (CronTrigger) triggerBuilder.build();

            // 调度容器设置JobDetail和Trigger
            sched.scheduleJob(jobDetail, trigger);

            // 启动
            if (!sched.isShutdown()) {
                sched.start();
            }
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }

    /**

                /** 方式二：先删除，然后在创建一个新的Job  */
                //JobDetail jobDetail = sched.getJobDetail(JobKey.jobKey(jobName, jobGroupName));
                //Class jobClass = jobDetail.getJobClass();
                //removeJob(jobName, jobGroupName, triggerName, triggerGroupName);

                /** 方式二 ：先删除，然后在创建一个新的Job */
            }
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }

    @ApiOperation(value = "移除一个任务")
    @RequestMapping("/removeJob")
    public void removeJob(String jobName, String jobGroupName,
                          String triggerName, String triggerGroupName) {
        try {
            Scheduler sched = schedulerFactory.getScheduler();

            TriggerKey triggerKey = TriggerKey.triggerKey(triggerName, triggerGroupName);

            sched.pauseTrigger(triggerKey);// 停止触发器
            sched.unscheduleJob(triggerKey);// 移除触发器
            sched.deleteJob(JobKey.jobKey(jobName, jobGroupName));// 删除任务
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }

    /**

            sched.start();
        } catch (Exception e) {

    public void shutdownJobs() {
        try {
            Scheduler sched = schedulerFactory.getScheduler();
            if (!sched.isShutdown()) {
                sched.shutdown();
            }
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }
}

  比如要删除一个job，只需要这样调用：http://localhost:8080/lfwer/quartz/removeJob?jobName=xxJob&triggerName=xxTrigger。因为我的groupName是默认的“DEFAULT”，所以不用传。
