SpringBoot学习-持久化Quartz定时任务管理

上一篇讲述了简单的QuartZ定时器的配置，这一次说一下持久化处理过程。
参考博文：http://blog.csdn.net/u012907049/article/details/73801122
首先是配置文件-quartz.properties：

# 固定前缀org.quartz# 主要分为scheduler、threadPool、jobStore、plugin等部分##org.quartz.scheduler.instanceName = DefaultQuartzSchedulerorg.quartz.scheduler.rmi.export = falseorg.quartz.scheduler.rmi.proxy = falseorg.quartz.scheduler.wrapJobExecutionInUserTransaction = false# 实例化ThreadPool时，使用的线程类为SimpleThreadPoolorg.quartz.threadPool.class = org.quartz.simpl.SimpleThreadPool# threadCount和threadPriority将以setter的形式注入ThreadPool实例# 并发个数org.quartz.threadPool.threadCount = 5# 优先级org.quartz.threadPool.threadPriority = 5org.quartz.threadPool.threadsInheritContextClassLoaderOfInitializingThread = trueorg.quartz.jobStore.misfireThreshold = 5000# 默认存储在内存中#org.quartz.jobStore.class = org.quartz.simpl.RAMJobStore#持久化org.quartz.jobStore.class = org.quartz.impl.jdbcjobstore.JobStoreTXorg.quartz.jobStore.tablePrefix = QRTZ_org.quartz.jobStore.dataSource = qzDSorg.quartz.dataSource.qzDS.driver = com.mysql.jdbc.Driverorg.quartz.dataSource.qzDS.URL = jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=UTF-8org.quartz.dataSource.qzDS.user = rootorg.quartz.dataSource.qzDS.password = 123456org.quartz.dataSource.qzDS.maxConnections = 10

比上一篇配置更详细，我参考的，有兴趣可以了解看看
接下里就是配置类-SchedulerConfig：

package com.example.demo.quartz;import org.quartz.Scheduler;import org.quartz.SchedulerException;import org.quartz.ee.servlet.QuartzInitializerListener;import org.springframework.beans.factory.config.PropertiesFactoryBean;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import org.springframework.core.io.ClassPathResource;import org.springframework.scheduling.quartz.SchedulerFactoryBean;import javax.sql.DataSource;import java.io.IOException;import java.util.Properties;@Configurationpublic class SchedulerConfig {    @Bean    public SchedulerFactoryBean schedulerFactoryBean(DataSource dataSource) throws IOException, SchedulerException {        SchedulerFactoryBean factory = new SchedulerFactoryBean();        factory.setQuartzProperties(quartzProperties());        Scheduler scheduler = factory.getScheduler();        if(null != scheduler ){            scheduler.start();        }        return factory;    }    @Bean    public Properties quartzProperties() throws IOException {        PropertiesFactoryBean propertiesFactoryBean = new PropertiesFactoryBean();        propertiesFactoryBean.setLocation(new ClassPathResource("/quartz.properties"));        return propertiesFactoryBean.getObject();    }    @Bean    public QuartzInitializerListener executorListener() {        return new QuartzInitializerListener();    }}

Job管理接口-JobController：

package com.example.demo.controller;import com.example.demo.entities.JobDto;import org.quartz.*;import org.quartz.impl.StdSchedulerFactory;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import org.springframework.web.bind.annotation.*;/** * Created by John.Zhang on 2017/10/25. */@RestController@RequestMapping(value="/job")public class JobController{//    @Autowired//    private IJobAndTriggerService iJobAndTriggerService;    private static Logger log = LoggerFactory.getLogger(JobController.class);    @PostMapping(value="/addjob")    public void addjob(@RequestBody JobDto jobDto) throws Exception    {        addJob(jobDto.getJobClassName(), jobDto.getJobGroupName(), jobDto.getCronExpression());    }    public static void addJob(String jobClassName, String jobGroupName, String cronExpression)throws Exception{        // 通过SchedulerFactory获取一个调度器实例        SchedulerFactory sf = new StdSchedulerFactory();        Scheduler sched = sf.getScheduler();        // 启动调度器        sched.start();        //构建job信息        JobDetail jobDetail = JobBuilder.newJob(getClass(jobClassName).getClass()).withIdentity(jobClassName, jobGroupName).build();        //表达式调度构建器(即任务执行的时间)        CronScheduleBuilder scheduleBuilder = CronScheduleBuilder.cronSchedule(cronExpression);        //按新的cronExpression表达式构建一个新的trigger        CronTrigger trigger = TriggerBuilder.newTrigger().withIdentity(jobClassName, jobGroupName)                .withSchedule(scheduleBuilder).build();        try {            sched.scheduleJob(jobDetail, trigger);        } catch (SchedulerException e) {            System.out.println("创建定时任务失败"+e);            throw new Exception("创建定时任务失败");        }    }    @PostMapping(value="/pausejob")    public void pausejob(@RequestBody JobDto jobDto) throws Exception    {        jobPause(jobDto.getJobClassName(), jobDto.getJobGroupName());    }    public static void jobPause(String jobClassName, String jobGroupName) throws Exception    {        // 通过SchedulerFactory获取一个调度器实例        SchedulerFactory sf = new StdSchedulerFactory();        Scheduler sched = sf.getScheduler();        sched.pauseJob(JobKey.jobKey(jobClassName, jobGroupName));    }    @PostMapping(value="/resumejob")    public void resumejob(@RequestBody JobDto jobDto) throws Exception    {        jobresume(jobDto.getJobClassName(), jobDto.getJobGroupName());    }    public static void jobresume(String jobClassName, String jobGroupName) throws Exception    {        // 通过SchedulerFactory获取一个调度器实例        SchedulerFactory sf = new StdSchedulerFactory();        Scheduler sched = sf.getScheduler();        sched.resumeJob(JobKey.jobKey(jobClassName, jobGroupName));    }    @PostMapping(value="/reschedulejob")    public void rescheduleJob(@RequestBody JobDto jobDto) throws Exception    {        jobreschedule(jobDto.getJobClassName() , jobDto.getJobGroupName(), jobDto.getCronExpression());    }    public static void jobreschedule(String jobClassName, String jobGroupName, String cronExpression) throws Exception    {        try {            SchedulerFactory schedulerFactory = new StdSchedulerFactory();            Scheduler scheduler = schedulerFactory.getScheduler();            TriggerKey triggerKey = TriggerKey.triggerKey(jobClassName, jobGroupName);            // 表达式调度构建器            CronScheduleBuilder scheduleBuilder = CronScheduleBuilder.cronSchedule(cronExpression);            CronTrigger trigger = (CronTrigger) scheduler.getTrigger(triggerKey);            // 按新的cronExpression表达式重新构建trigger            trigger = trigger.getTriggerBuilder().withIdentity(triggerKey).withSchedule(scheduleBuilder).build();            // 按新的trigger重新设置job执行            scheduler.rescheduleJob(triggerKey, trigger);        } catch (SchedulerException e) {            System.out.println("更新定时任务失败"+e);            throw new Exception("更新定时任务失败");        }    }    @PostMapping(value="/deletejob")    public void deletejob(@RequestBody JobDto jobDto) throws Exception    {        jobdelete(jobDto.getJobClassName(), jobDto.getJobGroupName());    }    public static void jobdelete(String jobClassName, String jobGroupName) throws Exception    {        // 通过SchedulerFactory获取一个调度器实例        SchedulerFactory sf = new StdSchedulerFactory();        Scheduler sched = sf.getScheduler();        sched.pauseTrigger(TriggerKey.triggerKey(jobClassName, jobGroupName));        sched.unscheduleJob(TriggerKey.triggerKey(jobClassName, jobGroupName));        sched.deleteJob(JobKey.jobKey(jobClassName, jobGroupName));    }    /*@GetMapping(value="/queryjob")    public Map<String, Object> queryjob(@RequestParam(value="pageNum")Integer pageNum, @RequestParam(value="pageSize")Integer pageSize)    {        PageInfo<JobAndTrigger> jobAndTrigger = iJobAndTriggerService.getJobAndTriggerDetails(pageNum, pageSize);        Map<String, Object> map = new HashMap<String, Object>();        map.put("JobAndTrigger", jobAndTrigger);        map.put("number", jobAndTrigger.getTotal());        return map;    }*/    public static Job getClass(String classname) throws Exception    {        Class<?> class1 = Class.forName(classname);        return (Job)class1.newInstance();    }}

前后台传递实体类-JobDto ：

package com.example.demo.entities;/** * Created by John.Zhang on 2017/10/25. */public class JobDto {    private String jobClassName;    private String jobGroupName;    private String cronExpression;    public String getJobClassName() {        return jobClassName;    }    public void setJobClassName(String jobClassName) {        this.jobClassName = jobClassName;    }    public String getJobGroupName() {        return jobGroupName;    }    public void setJobGroupName(String jobGroupName) {        this.jobGroupName = jobGroupName;    }    public String getCronExpression() {        return cronExpression;    }    public void setCronExpression(String cronExpression) {        this.cronExpression = cronExpression;    }}

其他的调用接口执行就行，使用页面、测试类或者类似于PostMan之类的测试工具都可以
