任务调度Quartz 2框架 页面配置调度任务
spring整合Quart 任务信息持久化到数据库,实现可以在页面配置任务 新增 暂定 删除 恢复 任务
1.定时任务配置类
/**
* 定时任务配置
*
*/
@Configuration
public class ScheduleConfig {
@Bean
public SchedulerFactoryBean schedulerFactoryBean(@Qualifier("dataSource")DataSource dataSource) {
SchedulerFactoryBean factory = new SchedulerFactoryBean();
factory.setDataSource(dataSource);
//quartz参数
Properties prop = new Properties();
prop.put("org.quartz.scheduler.instanceName", "KedaScheduler");
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", "false");
prop.put("org.quartz.jobStore.clusterCheckinInterval", "15000");
prop.put("org.quartz.jobStore.maxMisfiresToHandleAtATime", "1");
prop.put("org.quartz.jobStore.misfireThreshold", "12000");
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);
factory.setSchedulerName("kedaScheduler");
//延时启动
factory.setStartupDelay(30);
factory.setApplicationContextSchedulerContextKey("applicationContextKey");
//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;
}
}
2.建表语句

3.实体类

4.项目启动时初始化定时器
/**
* 项目启动时，初始化定时器
*/
@PostConstruct
public void init(){
// TODO 查询全部job
Map<String,Object> map = new HashMap<>();
List<ScheduleJobEntity> scheduleJobList = dalClient.queryForList("scheduleJob.getJobPage",map,ScheduleJobEntity.class);
for(ScheduleJobEntity scheduleJob : scheduleJobList){
CronTrigger cronTrigger = ScheduleUtils.getCronTrigger(scheduler, scheduleJob.getJobId());
//如果不存在，则创建
if(cronTrigger == null) {
ScheduleUtils.createScheduleJob(scheduler, scheduleJob);
}else {
ScheduleUtils.updateScheduleJob(scheduler, scheduleJob);
}
}
}
5.主要类,任务调度类
**
* 定时任务
*
*/
public class ScheduleJob extends QuartzJobBean {
private Logger logger = LoggerFactory.getLogger(getClass());
@Override
public void executeInternal(JobExecutionContext context) throws JobExecutionException {
ScheduleJobLogService scheduleJobLogService = (ScheduleJobLogService)SpringContextUtils.getBean("scheduleJobLogService");
SendmaillEventPublisher sendMail = (SendmaillEventPublisher)SpringContextUtils.getBean("sendmaillEventPublisher");
ScheduleJobEntity scheduleJob = (ScheduleJobEntity) context.getMergedJobDataMap()
.get(ScheduleJobEntity.JOB_PARAM_KEY);
//数据库保存执行记录
ScheduleJobLogEntity log = new ScheduleJobLogEntity();
log.setJobId(scheduleJob.getJobId());
log.setBeanName(scheduleJob.getBeanName());
log.setParams(scheduleJob.getParams());
log.setCreateTime(DateUtils.getCurrentSecond());
//任务开始时间
long startTime = System.currentTimeMillis();
try {
//执行任务
logger.debug("任务准备执行，任务ID：" + scheduleJob.getJobId());
//获取定时任务处理类
ITask target = SpringContextUtils.getBean(scheduleJob.getBeanName(), ITask.class);
target.run( scheduleJob.getParams());
//通过反射执行任务
Object target = SpringContextUtils.getBean(scheduleJob.getBeanName());
Method method = target.getClass().getDeclaredMethod("run", String.class);
method.invoke(target,scheduleJob.getParams());
//任务执行总时长
long times = System.currentTimeMillis() - startTime;
log.setTimes((int)times);
//任务状态 0：成功 1：失败
log.setStatus(0);
logger.debug("任务执行完毕，任务ID：" + scheduleJob.getJobId() + " 总共耗时：" + times + "毫秒");
}catch (Exception e) {
logger.error("任务执行失败，任务ID：" + scheduleJob.getJobId(), e);
//任务执行总时长
long times = System.currentTimeMillis() - startTime;
log.setTimes((int)times);
//任务状态 0：成功 1：失败
log.setStatus(1);
log.setError(StringUtils.substring(e.toString(), 0, 2000));
if(e instanceof InvocationTargetException){
//具体异常
Throwable t = ((InvocationTargetException) e).getTargetException();// 获取目标异常
log.setError(StringUtils.substring(t.toString(), 0, 2000));
}
sendMail.sendmailTaskLog(log);
}finally {
scheduleJobLogService.save(log);
}
}
}
6.任务调度工具类 重要
/**
* 定时任务工具类
*
*/
public class ScheduleUtils {
private final static String JOB_NAME = "TASK_";
/**
* 获取触发器key
*/
public static TriggerKey getTriggerKey(Long jobId) {
return TriggerKey.triggerKey(JOB_NAME + jobId);
}
/**
* 获取jobKey
*/
public static JobKey getJobKey(Long jobId) {
return JobKey.jobKey(JOB_NAME + jobId);
}
/**
* 获取表达式触发器
*/
public static CronTrigger getCronTrigger(Scheduler scheduler, Long jobId) {
try {
return (CronTrigger) scheduler.getTrigger(getTriggerKey(jobId));
} catch (SchedulerException e) {
throw new DiyException("获取定时任务CronTrigger出现异常", e);
}
}
/**
* 创建定时任务
*/
public static void createScheduleJob(Scheduler scheduler, ScheduleJobEntity scheduleJob) {
try {
//构建job信息
JobDetail jobDetail = JobBuilder.newJob(ScheduleJob.class).withIdentity(getJobKey(scheduleJob.getJobId())).build();
//表达式调度构建器
CronScheduleBuilder scheduleBuilder = CronScheduleBuilder.cronSchedule(scheduleJob.getCronExpression())
.withMisfireHandlingInstructionDoNothing();
//按新的cronExpression表达式构建一个新的trigger
CronTrigger trigger = TriggerBuilder.newTrigger().withIdentity(getTriggerKey(scheduleJob.getJobId())).withSchedule(scheduleBuilder).build();
//放入参数，运行时的方法可以获取
jobDetail.getJobDataMap().put(ScheduleJobEntity.JOB_PARAM_KEY, scheduleJob);
scheduler.scheduleJob(jobDetail, trigger);
//暂停任务
if(scheduleJob.getStatus() == TaskConstant.ScheduleStatus.PAUSE.getValue()){
pauseJob(scheduler, scheduleJob.getJobId());
}
} catch (SchedulerException e) {
throw new DiyException("创建定时任务失败", e);
}
}
/**
* 更新定时任务
*/
public static void updateScheduleJob(Scheduler scheduler, ScheduleJobEntity scheduleJob) {
try {
TriggerKey triggerKey = getTriggerKey(scheduleJob.getJobId());
//表达式调度构建器
CronScheduleBuilder scheduleBuilder = CronScheduleBuilder.cronSchedule(scheduleJob.getCronExpression())
.withMisfireHandlingInstructionDoNothing();
CronTrigger trigger = getCronTrigger(scheduler, scheduleJob.getJobId());
//按新的cronExpression表达式重新构建trigger
trigger = trigger.getTriggerBuilder().withIdentity(triggerKey).withSchedule(scheduleBuilder).build();
//参数
trigger.getJobDataMap().put(ScheduleJobEntity.JOB_PARAM_KEY, scheduleJob);
scheduler.rescheduleJob(triggerKey, trigger);
//暂停任务
if(scheduleJob.getStatus() == TaskConstant.ScheduleStatus.PAUSE.getValue()){
pauseJob(scheduler, scheduleJob.getJobId());
}
} catch (SchedulerException e) {
throw new DiyException("更新定时任务失败", e);
}
}
/**
* 立即执行任务
*/
public static void run(Scheduler scheduler, ScheduleJobEntity scheduleJob) {
try {
//参数
JobDataMap dataMap = new JobDataMap();
dataMap.put(ScheduleJobEntity.JOB_PARAM_KEY, scheduleJob);
scheduler.triggerJob(getJobKey(scheduleJob.getJobId()), dataMap);
} catch (SchedulerException e) {
throw new DiyException("立即执行定时任务失败", e);
}
}
/**
* 暂停任务
*/
public static void pauseJob(Scheduler scheduler, Long jobId) {
try {
scheduler.pauseJob(getJobKey(jobId));
} catch (SchedulerException e) {
throw new DiyException("暂停定时任务失败", e);
}
}
/**
* 恢复任务
*/
public static void resumeJob(Scheduler scheduler, Long jobId) {
try {
scheduler.resumeJob(getJobKey(jobId));
} catch (SchedulerException e) {
throw new DiyException("恢复定时任务失败", e);
}
}
/**
* 删除定时任务
*/
public static void deleteScheduleJob(Scheduler scheduler, Long jobId) {
try {
scheduler.deleteJob(getJobKey(jobId));
} catch (SchedulerException e) {
throw new DiyException("删除定时任务失败", e);
}
}
}
7.定时任务接口
/**
* 定时任务接口，所有定时任务都要实现该接口
*/
public interface ITask {
/**
* 执行定时任务接口
*
* @param params 参数，多参数使用JSON数据
*/
void run(String params);
}
