介绍

Quartz是OpenSymphony开源组织在Job scheduling领域又一个开源项目,它可以与J2EE与J2SE应用程序相结合也可以单独使用。Quartz可以用来创建简单或为运行十个,百个,甚至是好几万个Jobs这样复杂的程序。Jobs可以做成标准的Java组件或EJBs。Quartz的最新版本为Quartz 2.3.2。

quartz可以在某一个有规律的时间点干某件事,是一个任务调度框架,可以被集成到java的各种应用中使用,quartz框架可以支持分布式任务处理

基于springboot创建的web项目整合Quartz框架

整体代码结构

在这里插入图片描述

导入依赖

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

创建quartz_demo数据库,执行tables_mysql_innodb.sql文件创建对应表,下面是文件内容

#
# In your Quartz properties file, you'll need to set
# org.quartz.jobStore.driverDelegateClass = org.quartz.impl.jdbcjobstore.StdJDBCDelegate
#
#
# By: Ron Cordell - roncordell
#  I didn't see this anywhere, so I thought I'd post it here. This is the script from Quartz to create the tables in a MySQL database, modified to use INNODB instead of MYISAM.

写两条数据

在这里插入图片描述

依次实现mvc三层

mapper层的xml文件

<?xml version="1.0" encoding="UTF-8"?>

    </sql>
</mapper>

mapper接口


public interface SysJobMapper extends BaseMapper<SysJob> {

}

service接口

public interface SysJobService extends IService<SysJob> {

}

service接口实现

@Service
public class SysJobServiceImpl extends ServiceImpl<SysJobMapper, SysJob> implements SysJobService {
    @Autowired
    private Scheduler scheduler;
    @Autowired
    private ScheduleUtils scheduleUtils;

    
    @PostConstruct
    public void init() throws SchedulerException, TaskException {
        scheduler.clear();
        List<SysJob> jobList = baseMapper.selectList(null);
        for (SysJob job : jobList) {
            scheduleUtils.createScheduleJob(scheduler, job);
        }
    }
}

controller代码

@RestController
@RequestMapping("/job")
public class SysJobController {
    @Resource
    private SysJobService sysJobService;
    @Resource
    private ScheduleUtils scheduleUtils;
    @Resource
    private Scheduler scheduler;

    @PostMapping("/add")
    public Object add(@RequestBody SysJob entity) throws SchedulerException, TaskException {
        sysJobService.save(entity);
        scheduleUtils.createScheduleJob(scheduler, entity);
        return "ok";
    }
}

ScheduleUtils 定时任务工具类


@Component
public class ScheduleUtils {

    @Autowired
    private Scheduler scheduler;

    
    public TriggerKey getTriggerKey(String jobName, String jobGroup) {
        return TriggerKey.triggerKey(jobName, jobGroup);
    }

    
    public JobKey getJobKey(String jobName, String jobGroup) {
        return JobKey.jobKey(jobName, jobGroup);
    }

    
    public void createScheduleJob(Scheduler scheduler, SysJob job) throws SchedulerException, TaskException {
        // 构建job信息
        String jobName = job.getJobId() + "_" + job.getJobName();
        String jobGroupName = job.getJobGroupName();

        //TODO 反射动态获取Job实现类
        //构建job实例
        JobDetail jobDetail = JobBuilder.newJob(QuartzJobImpl.class)
                .withIdentity(getJobKey(jobName, jobGroupName))
                .build();
        jobDetail.getJobDataMap().put("QuartzJobExecutionData", job);
        // 表达式调度构建器
        CronScheduleBuilder cronScheduleBuilder = CronScheduleBuilder.cronSchedule(job.getCronExpression());
        cronScheduleBuilder = handleCronScheduleMisfirePolicy(job, cronScheduleBuilder);

        // 按新的cronExpression表达式构建一个新的trigger
        CronTrigger trigger = TriggerBuilder.newTrigger().withIdentity(getTriggerKey(jobName, jobGroupName))
                .withSchedule(cronScheduleBuilder).build();

        // 放入参数,运行时的方法可以获取
        jobDetail.getJobDataMap().put("QuartzJobExecutionData", job);

        // 判断是否存在
        if (scheduler.checkExists(getJobKey(jobName, jobGroupName))) {
            // 防止创建时存在数据问题 先移除,然后在执行创建操作
            scheduler.deleteJob(getJobKey(jobName, jobGroupName));
        }

        //创建定时任务调度
        scheduler.scheduleJob(jobDetail, trigger);

        // 暂停任务 规定 0启动 1暂停
        if (job.getStatus().equals("1")) {
            scheduler.pauseJob(getJobKey(jobName, jobGroupName));
        }
    }


    
    public void deleteScheduleJob(SysJob sysJob) throws SchedulerException {
        scheduler.deleteJob(getJobKey(sysJob.getJobId() + "_" + sysJob.getJobName(), sysJob.getJobGroupName()));
    }


    
    public CronScheduleBuilder handleCronScheduleMisfirePolicy(SysJob sysJob, CronScheduleBuilder cronScheduleBuilder) throws TaskException {
        switch (sysJob.getMisfirePolicy()) {
            case "0":
                return cronScheduleBuilder;
            case "1":
                return cronScheduleBuilder.withMisfireHandlingInstructionIgnoreMisfires();
            case "2":
                return cronScheduleBuilder.withMisfireHandlingInstructionFireAndProceed();
            case "3":
                return cronScheduleBuilder.withMisfireHandlingInstructionDoNothing();
            default:
                throw new TaskException("任务失败策略 '" + sysJob.getMisfirePolicy()
                        + "' 不能在cron计划任务中使用", TaskException.Code.CONFIG_ERROR);
        }
    }
}

创建一个Job实现类,只是一个简单实现类,没有对方法添加参数

@Slf4j
@Component
public class QuartzJobImpl implements Job {

    @Autowired
    private ApplicationContext context;

    @SneakyThrows
    @Override
    public void execute(JobExecutionContext jobExecutionContext) throws JobExecutionException {
        SysJob sysJob = new SysJob();
        BeanUtils.copyProperties(jobExecutionContext.getMergedJobDataMap().get("QuartzJobExecutionData"), sysJob);
        log.info("正在执行任务");
        String invokeTarget = sysJob.getInvokeTarget();
        String beanName = invokeTarget.split("\\.")[0];
        String methodName = invokeTarget.split("\\.")[1];
        Object bean = context.getBean(beanName);
        Class<?> clazz = bean.getClass();
        Method method = clazz.getMethod(methodName);
        method.invoke(bean);
        log.info("已结束任务");
        System.out.println();
    }
}

创建最终任务执行类,执行函数级别的定时任务,数据库中的invoke_target是和这里放入spring中的名称相同的,quartz_target.hello最终执行的函数就是hello函数

@Slf4j
@Component("quartz_target")
public class QuartzJobExe {

    @Resource
    private Scheduler scheduler;

    public void hello() throws Exception {
        System.out.println("[job]实例执行...hello..." + System.currentTimeMillis());
    }

    public void action() throws Exception {
        System.out.println("[job]实例执行...action..." + System.currentTimeMillis());
    }
}

最终代码结构

启动spring boot之后的任务状态

在这里插入图片描述

使用postman工具类添加一个任务

在这里插入图片描述

然后在代码中添加一个对应的方法

在这里插入图片描述

重新启动springboot的运行结果

理论上使用这样的反射方式可以运行任何代码的
