    springboot + quartz + mysql 实现持久化分布式调度

    1. 官方文档:http://www.quartz-scheduler.org/documentation/quartz-2.3.0/
    2. 中文文档:https://www.w3cschool.cn/quartz_doc/quartz_doc-2put2clm.html

    1. 获取 sql 脚本文件,创建数据库

    在官网下载好包后,在 quartz-2.3.0-SNAPSHOTsrcorgquartzimpljdbcjobstore 目录下可以选择适合自己的数据库脚本文件
    我使用的数据库是mysql,因此我也将sql脚本放到了本项目的 resources 目录下

    commit;
    

    2. 创建springboot项目,导入maven依赖包

            <dependency>
                <groupId>com.mchange</groupId>
                <artifactId>c3p0</artifactId>
                <version>0.9.5.4</version>
            </dependency>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-quartz</artifactId>
                <version>2.3.3.RELEASE</version>
            </dependency>
            <dependency>
                <groupId>mysql</groupId>
                <artifactId>mysql-connector-java</artifactId>
                <scope>runtime</scope>
            </dependency>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-jdbc</artifactId>
            </dependency>
    

    3. 在 resources 目录下创建 quartz 的配置文件 quartz.properties

    #quartz集群配置
    # ===========================================================================
    # Configure Main Scheduler Properties 调度器属性
    # ===========================================================================
    #调度标识名 集群中每一个实例都必须使用相同的名称
    org.quartz.scheduler.instanceName=DefaultQuartzScheduler
    #ID设置为自动获取 每一个必须不同
    org.quartz.scheduler.instanceid=AUTO
    #============================================================================
    # Configure ThreadPool
    #============================================================================
    #线程池的实现类(一般使用SimpleThreadPool即可满足几乎所有用户的需求)
    org.quartz.threadPool.class=org.quartz.simpl.SimpleThreadPool
    #指定线程数,至少为1(无默认值)(一般设置为1-100直接的整数合适)
    org.quartz.threadPool.threadCount=25
    #设置线程的优先级(最大为java.lang.Thread.MAX_PRIORITY 10,最小为Thread.MIN_PRIORITY 1,默认为5)
    org.quartz.threadPool.threadPriority=5
    #============================================================================
    # Configure JobStore
    #============================================================================
    # 信息保存时间 默认值60秒
    org.quartz.jobStore.misfireThreshold=60000
    #数据保存方式为数据库持久化
    org.quartz.jobStore.class=org.quartz.impl.jdbcjobstore.JobStoreTX
    #数据库代理类,一般org.quartz.impl.jdbcjobstore.StdJDBCDelegate可以满足大部分数据库
    org.quartz.jobStore.driverDelegateClass=org.quartz.impl.jdbcjobstore.StdJDBCDelegate
    #JobDataMaps是否都为String类型
    org.quartz.jobStore.useProperties=false
    #数据库别名 随便取
    org.quartz.jobStore.dataSource=myDS
    #表的前缀,默认QRTZ_
    org.quartz.jobStore.tablePrefix=QRTZ_
    #是否加入集群
    org.quartz.jobStore.isClustered=true
    #调度实例失效的检查时间间隔
    org.quartz.jobStore.clusterCheckinInterval=20000
    #============================================================================
    # Configure Datasources
    #============================================================================
    #数据库引擎
    org.quartz.dataSource.myDS.driver=com.mysql.cj.jdbc.Driver
    #数据库连接
    org.quartz.dataSource.myDS.URL=jdbc:mysql://localhost:3306/quartz?characterEncoding=utf8&allowMultiQueries=true&useSSL=false&autoReconnect=true&serverTimezone=UTC
    #数据库用户
    org.quartz.dataSource.myDS.user=root
    #数据库密码
    org.quartz.dataSource.myDS.password=root
    #允许最大连接
    org.quartz.dataSource.myDS.maxConnections=5
    #验证查询sql,可以不设置
    org.quartz.dataSource.myDS.validationQuery=select 0 from dual
    

    4. 注册Quartz任务工厂(TaskJobFactory)

    @Component
    public class TaskJobFactory extends AdaptableJobFactory {
        @Autowired
        AutowireCapableBeanFactory capableBeanFactory;
    
        @Override
        protected Object createJobInstance(TriggerFiredBundle bundle) throws Exception {
            //调用父类的方法
            Object jobInstance = super.createJobInstance(bundle);
            //进行注入
            capableBeanFactory.autowireBean(jobInstance);
            return jobInstance;
        }
    }
    

    5. 注册调度工厂,以及生成调度实例

    若要在该服务启动时,就执行调度任务,需要将 factory.setAutoStartup(false); 改为 factory.setAutoStartup(true);

    @Configuration
    public class QuartzConfig {
        @Autowired
        DataSource dataSource;
    
        @Autowired
        TaskJobFactory jobFactory;
    
        @Bean(name = "SchedulerFactory")
        public SchedulerFactoryBean schedulerFactoryBean() throws IOException {
            //获取配置属性
            PropertiesFactoryBean propertiesFactoryBean = new PropertiesFactoryBean();
            propertiesFactoryBean.setLocation(new ClassPathResource("/quartz.properties"));
            //在quartz.properties中的属性被读取并注入后再初始化对象
            propertiesFactoryBean.afterPropertiesSet();
            //创建SchedulerFactoryBean
            SchedulerFactoryBean factory = new SchedulerFactoryBean();
            //将配置文件中的信息添加到调度工厂中
            //对应java应用程序中的 new StdSchedulerFactory(properties)
            factory.setQuartzProperties(propertiesFactoryBean.getObject());
            factory.setJobFactory(jobFactory);
            // 默认的自动执行调度,这里设置为不自动执行调度,
            // 为了方便扩展集群分布式调度任务,这个服务只配置调度,另外启动一个或多个服务执行调度
            factory.setAutoStartup(false);
            return factory;
        }
    
        /*
         * 通过SchedulerFactoryBean获取Scheduler的实例
         */
        @Bean(name = "scheduler")
        public Scheduler scheduler() throws IOException, SchedulerException {
            Scheduler scheduler = schedulerFactoryBean().getScheduler();
            return scheduler;
        }
    }
    

    6. Quartz服务层接口(QuartzService)

    public interface QuartzService {
        /**
         * 添加任务可以传参数
         *
         * @param clazz
         * @param jobName
         * @param groupName
         * @param cronExp
         * @param param
         */
        void addJob(Class clazz, String jobName, String groupName, String cronExp, Map<String, Object> param);
    
        /**
         * 暂停任务
         *
         * @param name
         * @param groupName
         */
        void pauseJob(String name, String groupName);
    
        /**
         * 恢复任务
         *
         * @param name
         * @param groupName
         */
        void resumeJob(String name, String groupName);
    
        /**
         * 更新任务
         *
         * @param name
         * @param groupName
         * @param cronExp
         * @param param
         */
        void updateJob(String name, String groupName, String cronExp, Map<String, Object> param);
    
        /**
         * 删除任务
         *
         * @param name
         * @param groupName
         */
        void deleteJob(String name, String groupName);
    
        /**
         * 启动所有任务
         */
        void startAllJobs();
    
        /**
         * 关闭所有任务
         */
        void shutdownAllJobs();
    }
    
    

    7. 任务调度服务接口实现类(QuartzServiceImpl)

    @Service
    public class QuartzServiceImpl implements QuartzService {
    
        @Autowired
        Scheduler scheduler;
    
    
        /**
         * 创建job,可传参
         *
         * @param clazz     任务类
         * @param name      任务名称
         * @param groupName 任务所在组名称
         * @param cronExp   cron表达式
         * @param param     map形式参数
         */
        @Override
        public void addJob(Class clazz, String name, String groupName, String cronExp, Map<String, Object> param) {
            try {
                // 启动调度器
    //            scheduler.start();
                //构建job信息
                //((Job) clazz.newInstance()).getClass()
                JobDetail jobDetail = JobBuilder.newJob(clazz).withIdentity(name, groupName).build();
                //表达式调度构建器(即任务执行的时间)
                CronScheduleBuilder scheduleBuilder = CronScheduleBuilder.cronSchedule(cronExp);
                //按新的cronExpression表达式构建一个新的trigger
                CronTrigger trigger = TriggerBuilder.newTrigger().withIdentity(name, groupName).withSchedule(scheduleBuilder).build();
                //获得JobDataMap,写入数据
                if (param != null) {
                    trigger.getJobDataMap().putAll(param);
                }
                scheduler.scheduleJob(jobDetail, trigger);
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    
        /**

            } catch (SchedulerException e) {

            }
        }

         */
        @Override

            try {

        }
    
        /**
         * job 删除
         * <p>
         * 同时删除 调度中的触发器 Trigger 和任务 job
         *
         * @param name      任务名称
         * @param groupName 任务所在组名称
         */
        @Override
        public void deleteJob(String name, String groupName) {
            try {
                scheduler.pauseTrigger(TriggerKey.triggerKey(name, groupName));
                scheduler.unscheduleJob(TriggerKey.triggerKey(name, groupName));
                scheduler.deleteJob(JobKey.jobKey(name, groupName));
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    
    
        /**
         * 启动所有定时任务
         */
        @Override
        public void startAllJobs() {
            try {
                scheduler.start();
            } catch (Exception e) {
                throw new RuntimeException(e);
            }
        }
    
        /**
         * 关闭所有定时任务
         */
        @Override
        public void shutdownAllJobs() {
            try {
                if (!scheduler.isShutdown()) {
                    // scheduler生命周期结束,无法再 start() 启动
                    scheduler.shutdown();
                }
            } catch (Exception e) {
                throw new RuntimeException(e);
            }
        }
    }
    

    8. 需要执行的任务(OrderTimeOutJob )

    public class OrderTimeOutJob implements Job {
        @Override
        public void execute(JobExecutionContext context) {
            //获取任务名
            String taskName = context.getJobDetail().getKey().getName();
            String groupName=context.getJobDetail().getKey().getGroup();
            System.out.println(String.format("task--->%s,%s",taskName,groupName));
            //todo:处理执行任务时的业务代码
        }
    }
    

    9. 编写接口类进行测试(JobController)

    @RestController
    public class JobController {
    
        @Autowired
        QuartzService service;
    
        /**
         * 添加新任务
         *
         * @return
         */
        @RequestMapping("/addJob")
        public Object addJob(@RequestParam String groupName, @RequestParam String jobName) {
            Map<String, Object> resultMap = new HashMap<>();
            //任务组名
    //        String groupName = "order3";
            //任务名
    //        String jobName = "20190724120322389224";
            //CRON表达式
            String cronExp = "* * * * * ? *";
            service.addJob(OrderTimeOutJob.class, jobName, groupName, cronExp, null);
            resultMap.put("groupName", groupName);
            resultMap.put("jobName", jobName);
            resultMap.put("cronExp", cronExp);
            return resultMap;
        }
    
        /**
         * 启动调度
         *
         * @return
         */
        @RequestMapping("/startAllJobs")
        public String startAllJobs() {
            service.startAllJobs();
            return "true";
        }
    
        /**
         * 关闭调度
         *
         * @return
         */
        @RequestMapping("/shutdownAllJobs")
        public String shutdownAllJobs() {
            service.shutdownAllJobs();
            return "true";
        }
    
        /**
         * 暂停某个调度
         *
         * @param groupName
         * @param jobName
         * @return
         */
        @RequestMapping("/pauseJob")
        public String pauseJob(@RequestParam String groupName, @RequestParam String jobName) {
            service.pauseJob(jobName, groupName);
            return "true";
        }
    
        /**
         * 恢复调度某个暂停的任务
         *
         * @param groupName
         * @param jobName
         * @return
         */
        @RequestMapping("/resumeJob")
        public String resumeJob(@RequestParam String groupName, @RequestParam String jobName) {
            service.resumeJob(jobName, groupName);
            return "true";
        }
    
        /**
         * 删除任务
         *
         * @return
         */
        @RequestMapping("/delJob")
        public Object delJob(@RequestParam String groupName, @RequestParam String jobName) {
            Map<String, Object> resultMap = new HashMap<>();
            //任务组名
            //任务名
            service.deleteJob(jobName, groupName);
            resultMap.put("groupName", groupName);
            resultMap.put("jobName", jobName);
            return resultMap;
        }
    }
    

    10. 最后添加配置文件 application.yml,启动项目

    spring:
      application:
        name: quartz
      datasource:
        url: jdbc:mysql://localhost:3306/quartz?characterEncoding=utf8&allowMultiQueries=true&useSSL=false&autoReconnect=true&serverTimezone=UTC
        username: root
        password: root
    

    总结

    1. 若需要随着上面项目的启动,就执行调度任务,需要将步骤5中 factory.setAutoStartup(false); 改为 factory.setAutoStartup(true);,或者直接删除 factory.setAutoStartup(false);
    2. 为了保证调度的高可用,重新创建一个或多个新项目用来执行调度,新项目中只需要配置上面的 2~5 步骤即可
      ,第五步将 factory.setAutoStartup(false); 改为 factory.setAutoStartup(true);,或者直接删除 factory.setAutoStartup(false);
