SpringBoot Schedule Quartz

前一段时间写了定时任务，记录在此。

1.maven 配置  此外还有11张表，官网有提供创建表sql 

　　<dependency>

    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-quartz</artifactId>
</dependency>
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context</artifactId>
</dependency>

表名

QRTZ_FIRED_TRIGGERS;
QRTZ_PAUSED_TRIGGER_GRPS;
QRTZ_SCHEDULER_STATE; -- 运行中实例的状态
QRTZ_LOCKS;
QRTZ_SIMPLE_TRIGGERS;
QRTZ_SIMPROP_TRIGGERS;
QRTZ_CRON_TRIGGERS; -- cron表达式
QRTZ_BLOB_TRIGGERS;
QRTZ_TRIGGERS; -- 每个定时任务的上次及下次执行时间, 执行状态(BLOCKED,WAITING等)
QRTZ_JOB_DETAILS;
QRTZ_CALENDARS

2.创建JobProperties类
@Getter
@Setter 
public class JobProperties {
　　
　　private final String jobName;
　　private final String jobGroup;
　　private final HashMap<String,String> jobParams;
　　private String cronExpression;
　　final Class< ? extends Job> jobRunner;

}

3.创建SchedulerModel类
@Getter
@Setter
public class SchedulerModel {
　　private final JobDetail jobDetail;
　　private final JobTrigger jobTrigger;
}

4.创建Model生成接口
public interface IschedulerModelGenerator {
　　SchedulerModel generateModelFrom(JobProperties  jobProperties);
}

5.Model接口实现
@Service
public class SchedulerModelGenerator implements IschedulerModelGenerator {
　　
　　

public  ScheduleModel generateModelFrom(JobProperties jobProperties) {
    JobDetail jobDetail = getJobDetailFor(jobProperties.getJobName(), jobProperties.getJobGroup(), jobProperties.getJobParams(),
            jobProperties.getJobRunner());

    Trigger trigger = getTriggerFor(jobDetail,jobProperties.getCronExpression());
    return new ScheduleModel(jobDetail, trigger);
}

private JobDetail getJobDetailFor(String jobName, String groupName, HashMap<String, String> jobParams, Class<? extends Job> jobRunner) {
    return JobBuilder.newJob(jobRunner)
            .setJobData(getJobDataMapFrom(jobParams))
            .withDescription(jobName  + groupName)
            .withIdentity(jobName, groupName)
            .storeDurably(false)
            .build();
}

private JobDataMap getJobDataMapFrom(HashMap<String, String> jobParams) {
    JobDataMap jobDataMap = new JobDataMap();
    for (Map.Entry<String, String> entry : jobParams.entrySet()) {
        jobDataMap.put(entry.getKey(), entry.getValue());
    }
    return jobDataMap;
}


private Trigger getTriggerFor(JobDetail jobDetail, String cronExpression) {

    return TriggerBuilder.newTrigger()
            .forJob(jobDetail)
            .withSchedule(cronSchedule(cronExpression))
            .build();
}

　
}

6.shceduler基础类

public abstract class CronSchedulerBase {

    private final SchedulerFactoryBean schedulerFactoryBean;
    private final ISchedulerModelGenerator schedulerModelGenerator;


    public CronSchedulerBase(SchedulerFactoryBean schedulerFactoryBean,
                             ISchedulerModelGenerator schedulerModelGenerator) {
        this.schedulerFactoryBean = schedulerFactoryBean;
        this.schedulerModelGenerator = schedulerModelGenerator;
    }

    @PostConstruct
    public void init() throws SchedulerException {
        scheduleJob();
    }

    private void scheduleJob() throws SchedulerException {

        JobProperties jobProperties = getJobProperties();

        Scheduler scheduler = schedulerFactoryBean.getScheduler();
        ScheduleModel scheduleModel = schedulerModelGenerator.generateModelFrom(jobProperties);

        if (scheduler.checkExists(scheduleModel.getJobDetail().getKey())){
            scheduler.deleteJob(scheduleModel.getJobDetail().getKey());
        }

        scheduler.scheduleJob(scheduleModel.getJobDetail(),scheduleModel.getTrigger());
        scheduler.start();

    }

    protected abstract   JobProperties getJobProperties();
}

7.创建TestScheduler

@Service
public class TestScheduler extends CronSchedulerBase {

    private static final String JOB_NAME = "TestScheduler";
    private static final String GROUP_NAME = "TestSchedulerGroup";
    private static final String CRON_EXPRESSION = "0 0 0/1 ? * * *"; 

    @Autowired
    public TestScheduler(SchedulerFactoryBean schedulerFactoryBean,
                                                        ISchedulerModelGenerator schedulerModelGenerator) {
        super(schedulerFactoryBean, schedulerModelGenerator);
    }


    @Override
    protected JobProperties getJobProperties() {
        return new JobProperties(JOB_NAME, GROUP_NAME, CRON_EXPRESSION, TestSchedulerJob.class);
    }
}

8.创建TestSchedulerJob

public class TestSchedulerJob implements Job {
　　
　　public void execute (JobExecutionContext jobExecutionContext) {
　　　　//业务逻辑
　　}
 }
