SpringBoot实现quartz定时任务可视化管理功能

前言

在实际框架或产品开发过程中，springboot中集成quarzt方式基本是以job和trigger的bean对象方式直接硬编码完成的，例如以下代码示例。对于系统内定义的所有定时任务类型，具体执行类，执行策略，运行状态都没有一个动态全局的管理，所有决定将quartz做成可视化配置管理，便于统一管理，也降低了使用门槛，只需要关心job类的实现即可

 @Bean
    public JobDetail SMSJobDetail() {
        return JobBuilder.newJob(SMSJob.class).withIdentity("SMSJob").storeDurably().build();
    }

    // 把jobDetail注册到trigger上去
    @Bean
    public Trigger myJobTrigger() {
        SimpleScheduleBuilder scheduleBuilder = SimpleScheduleBuilder.simpleSchedule()
                .withIntervalInSeconds(1).repeatForever();

        return TriggerBuilder.newTrigger()
                .forJob(SMSJobDetail())
                .withIdentity("myJobTrigger")
                .withSchedule(scheduleBuilder)
                .build();
    }

表结构

用于存储quartz配置

DROP TABLE IF EXISTS `f_quartztask`;
CREATE TABLE `f_quartztask` (
  `TaskID` varchar(50) NOT NULL,
  `TaskName` varchar(200) DEFAULT NULL,
  `TaskType` int(11) DEFAULT NULL,
  `TaskTag` varchar(100) DEFAULT NULL,
  `JobClassPath` varchar(200) DEFAULT NULL,
  `ExecutePeroid` int(11) DEFAULT NULL,
  `ExecuteUnit` int(11) DEFAULT NULL,
  `CornExpress` varchar(200) DEFAULT NULL,
  `Enviroment` varchar(50) DEFAULT NULL,
  `TaskStatus` int(11) DEFAULT NULL,
  `SortNum` int(11) DEFAULT NULL,
  `Remark` varchar(500) DEFAULT NULL,
  PRIMARY KEY (`TaskID`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4;

枚举类

public class QuartzEnum {
    public enum TaskType implements IConvertEnumToCodeItem {
        Cycle(10, "循环任务"), Corn(20, "Corn表达式任务");
        private int _value;
        private String _name;

        }

        @Override
        public String getCodeName() {

        @Override
        public String toString() {
            return _name;
        }

        @Override
        public String getCodeName() {
            return "Quartz间隔单位";
        }
    }

    public enum TaskStatus implements IConvertEnumToCodeItem {
        Open(10, "开启"), Close(20, "关闭");
        private int _value;
        private String _name;

        private TaskStatus(int value, String name) {

        }

        public void set_name(String _name) {
            this._name = _name;

}

QuartzFactory

支持Job类注bean入对象

@Component
public class QuartzFactory extends AdaptableJobFactory {
    @Autowired
    private 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;

    }
}

QuartzConfig

注入QuartzFactory对象

@Configuration
public class QuartzConfig {
    @Autowired
    private QuartzFactory quartzFactory;

    @Bean
    public SchedulerFactoryBean schedulerFactoryBean(){
        SchedulerFactoryBean schedulerFactoryBean = new SchedulerFactoryBean();
        schedulerFactoryBean.setJobFactory(quartzFactory);
        //将job实例化，能够操作进行Spring 注入
        return schedulerFactoryBean;
    }
}

QuartzUtil

定时任务动态添加/删除操作类，initQuartzTask方法在系统启动时执行，根据配置自动开启相关符合条件的任务

@Component
public class QuartzUtil {
    @Autowired
    private SchedulerFactoryBean schedulerFactoryBean;
    @Autowired
    private F_QuartzTaskService quartzTaskService;
    @Value("${spring.profiles.active}")
    private String active;
    private static String JOB_GROUP_NAME = "DEFAULT_JOB_GROUP_NAME";
    private static String TRIGGER_GROUP_NAME = "DEFAULT_TRIGGER_GROUP_NAME";

    public void initQuartzTask() {
        List<F_QuartzTaskDO> openTaskList = quartzTaskService.selectAllList();
        if(openTaskList.size()>0){
            openTaskList = openTaskList.stream().filter(a -> a.getTaskStatus() == QuartzEnum.TaskStatus.Open.get_value() &&
                    (a.getEnviroment().equals(QuartzEnum.TaskEnviroment.All.get_name()) || a.getEnviroment().equals(active))).collect(Collectors.toList());
        }
        for (F_QuartzTaskDO taskDO : openTaskList) {
            try {
                Class<Job> jobClass = (Class<Job>) Class.forName(taskDO.getJobClassPath());
                if (taskDO.getTaskType() == QuartzEnum.TaskType.Cycle.get_value()) {
                    addIntervalJob(taskDO.getTaskTag(), jobClass, taskDO.getExecutePeroid(), taskDO.getExecuteUnit());
                } else {
                    addCornJob(taskDO.getTaskTag(), jobClass, taskDO.getCornExpress());
                }
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
        if (openTaskList.size() > 0) {
            System.out.println("扫描并初始化开启quartz定时任务成功，任务数量：" + openTaskList.size() + "个");
        }
    }

    public void startTask( F_QuartzTaskDO taskDO){
        try {
            Class<Job> jobClass = (Class<Job>) Class.forName(taskDO.getJobClassPath());

        }

            } else if (timeUnit == QuartzEnum.ExecuteUnit.Minute.get_value()) {

            JobDetail jobDetail = JobBuilder.newJob(cls).withIdentity(jobName, JOB_GROUP_NAME).storeDurably().build();
            Trigger trigger = TriggerBuilder.newTrigger().forJob(jobDetail).withIdentity(jobName, TRIGGER_GROUP_NAME).withSchedule(scheduleBuilder).build();

            sched.scheduleJob(jobDetail, trigger);
            if (!sched.isShutdown()) {
                sched.start();        // 启动

        } catch (Exception e) {
