二、配置文件application.properties

## database
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
spring.datasource.url=jdbc:mysql://192.168.0.246:3306/hrz_task_center?useUnicode=true&characterEncoding=UTF-8&useSSL=false

spring.datasource.connectionProperties=druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500
spring.datasource.useGlobalDataSourceStat=true
# Druid监控器配置
#默认为stat,即开启sql监控。这里加了个wall,表示同时开启sql防火墙
spring.datasource.druid.filters=stat,wall,log4j
spring.datasource.druid.web-stat-filter.enabled=true

三、配置类ScheduleConfig

@Configuration
public class ScheduleConfig {
    @Bean
    public SchedulerFactoryBean schedulerFactoryBean(DataSource dataSource) {
        SchedulerFactoryBean factory = new SchedulerFactoryBean();
        //配置数据源
        factory.setDataSource(dataSource);
        //quartz参数
        Properties prop = new Properties();
        prop.put("org.quartz.scheduler.instanceName", "HrzScheduler");
        prop.put("org.quartz.scheduler.instanceId", "AUTO");
        //线程池配置
        prop.put("org.quartz.threadPool.class", "org.quartz.simpl.SimpleThreadPool");
        prop.put("org.quartz.threadPool.threadCount", "20");
        prop.put("org.quartz.threadPool.threadPriority", "5");
        //JobStore配置
        prop.put("org.quartz.jobStore.class", "org.quartz.impl.jdbcjobstore.JobStoreTX");
        //集群配置
        prop.put("org.quartz.jobStore.isClustered", "true");
        prop.put("org.quartz.jobStore.clusterCheckinInterval", "15000");
        prop.put("org.quartz.jobStore.maxMisfiresToHandleAtATime", "1");
        prop.put("org.quartz.jobStore.misfireThreshold", "12000");
        //前缀
        prop.put("org.quartz.jobStore.tablePrefix", "QRTZ_");
        prop.put("org.quartz.jobStore.selectWithLockSQL", "SELECT * FROM {0}LOCKS UPDLOCK WHERE LOCK_NAME = ?");

        //PostgreSQL数据库，需要打开此注释
        //prop.put("org.quartz.jobStore.driverDelegateClass", "org.quartz.impl.jdbcjobstore.PostgreSQLDelegate");
        factory.setQuartzProperties(prop);
        //调度名称
        factory.setSchedulerName("HrzScheduler");
        //延时启动
        factory.setStartupDelay(30);
        //可选，QuartzScheduler 启动时更新己存在的Job，这样就不用每次修改targetObject后删除qrtz_job_details表对应记录了
        factory.setOverwriteExistingJobs(true);
        //设置自动启动，默认为true
        factory.setAutoStartup(true);
        return factory;
    }
}

四、工具类

1、ScheduleJob
@Slf4j
public class ScheduleJob extends QuartzJobBean {
    private ExecutorService service = Executors.newSingleThreadExecutor();

    @Override
    protected void executeInternal(JobExecutionContext context) throws JobExecutionException {
        JobKey key = context.getJobDetail().getKey();
        log.info( "任务key:"+key);
        String json = context.getMergedJobDataMap().getString(ScheduleJobs.JOB_PARAM_KEY);
        //将获取的对象序列化的json 转化为实体类对象
        ScheduleJobs scheduleJobs = JSON.parseObject(json, ScheduleJobs.class);
        //获取spring bean
        ScheduleJobLogService scheduleJobLogService = (ScheduleJobLogService) SpringUtils.getBean("scheduleJobLogService");

        //数据库保存执行记录
        ScheduleJobLog scheduleJobLog = new ScheduleJobLog();

        scheduleJobLog.setJobId(scheduleJobs.getId());
        scheduleJobLog.setBeanName(scheduleJobs.getBeanName());
        scheduleJobLog.setMethodName(scheduleJobs.getMethodName());
        scheduleJobLog.setParams(scheduleJobs.getParams());
        scheduleJobLog.setCreateTime(new Date());

        //任务开始时间
        long startTime = System.currentTimeMillis();

        try {
            //执行任务
            log.info("任务准备执行，任务ID：" + scheduleJobs.getId());
            ScheduleRunnable task = new ScheduleRunnable(scheduleJobs.getBeanName(),
                    scheduleJobs.getMethodName(), scheduleJobs.getParams());
            //接收多线程的执行结果
            Future<?> future = service.submit(task);
            future.get();
            //任务执行总时长
            long times = System.currentTimeMillis() - startTime;
            scheduleJobLog.setTimes((int)times);
            //任务状态    0：成功    1：失败
            scheduleJobLog.setStatus(0);
            log.info("任务执行完毕，任务ID：" + scheduleJobs.getId() + "  总共耗时：" + times + "毫秒");
        } catch (Exception e) {
            log.error("任务执行失败，任务ID：" + scheduleJobs.getId(), e);

            //任务执行总时长
            long times = System.currentTimeMillis() - startTime;
            scheduleJobLog.setTimes((int)times);

            //任务状态    0：成功    1：失败
            scheduleJobLog.setStatus(1);
            scheduleJobLog.setError(StringUtils.substring(e.toString(), 0, 2000));
        }finally {
            //插入日志
            scheduleJobLogService.saveLog(scheduleJobLog);
        }
    }
}
