這篇“springboot創建的web項目如何整合Quartz框架”文章的知識點大部分人都不太理解,所以小編給大家總結了以下內容,內容詳細,步驟清晰,具有一定的借鑒價值,希望大家閱讀完這篇文章能有所收獲,下面我們一起來看看這篇“springboot創建的web項目如何整合Quartz框架”文章吧。
Quartz是OpenSymphony開源組織在Job scheduling領域又一個開源項目,它可以與J2EE與J2SE應用程序相結合也可以單獨使用。Quartz可以用來創建簡單或為運行十個,百個,甚至是好幾萬個Jobs這樣復雜的程序。Jobs可以做成標準的Java組件或EJBs。Quartz的最新版本為Quartz 2.3.2。
quartz可以在某一個有規律的時間點干某件事,是一個任務調度框架,可以被集成到java的各種應用中使用,quartz框架可以支持分布式任務處理

寫兩條數據

mapper接口
/** * Auto Generated * * @author :Boy * @date :Created in 2022-06-18 * @description: * @modified By: */ public interface SysJobMapper extends BaseMapper<SysJob> { }
service接口
public interface SysJobService extends IService<SysJob> { }
service接口實現
@Service public class SysJobServiceImpl extends ServiceImpl<SysJobMapper, SysJob> implements SysJobService { @Autowired private Scheduler scheduler; @Autowired private ScheduleUtils scheduleUtils; /** * 項目啟動時,初始化定時器 * 主要是防止手動修改數據庫導致未同步到定時任務處理(注:不能手動修改數據庫ID和任務組名,否則會導致臟數據) */ @PostConstruct public void init() throws SchedulerException, TaskException { scheduler.clear(); List<SysJob> jobList = baseMapper.selectList(null); for (SysJob job : jobList) { scheduleUtils.createScheduleJob(scheduler, job); } } }
controller代碼
@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 定時任務工具類
/** * @Author ScholarTang * @Date 2021/7/15 下午3:50 * @Desc 定時任務工具類 */ @Component public class ScheduleUtils { @Autowired private Scheduler scheduler; /** * 構建任務觸發對象 * * @param jobName * @param jobGroup * @return */ public TriggerKey getTriggerKey(String jobName, String jobGroup) { return TriggerKey.triggerKey(jobName, jobGroup); } /** * 構建任務鍵對象 * * @param jobName * @param jobGroup * @return */ public JobKey getJobKey(String jobName, String jobGroup) { return JobKey.jobKey(jobName, jobGroup); } /** * 創建定時調度任務 * * * @param scheduler * @param job * @throws SchedulerException * @throws TaskException */ public void createScheduleJob(Scheduler scheduler, SysJob job) throws SchedulerException, TaskException { // 構建job信息 String jobName = job.getJobId() + "_" + job.getJobName(); String jobGroupName = job.getJobGroupName(); //TODO 反射動態獲取Job實現類 //構建job實例 JobDetail jobDetail = JobBuilder.newJob(QuartzJobImpl.class) .withIdentity(getJobKey(jobName, jobGroupName)) .build(); jobDetail.getJobDataMap().put("QuartzJobExecutionData", job); // 表達式調度構建器 CronScheduleBuilder cronScheduleBuilder = CronScheduleBuilder.cronSchedule(job.getCronExpression()); cronScheduleBuilder = handleCronScheduleMisfirePolicy(job, cronScheduleBuilder); // 按新的cronExpression表達式構建一個新的trigger CronTrigger trigger = TriggerBuilder.newTrigger().withIdentity(getTriggerKey(jobName, jobGroupName)) .withSchedule(cronScheduleBuilder).build(); // 放入參數,運行時的方法可以獲取 jobDetail.getJobDataMap().put("QuartzJobExecutionData", job); // 判斷是否存在 if (scheduler.checkExists(getJobKey(jobName, jobGroupName))) { // 防止創建時存在數據問題 先移除,然后在執行創建操作 scheduler.deleteJob(getJobKey(jobName, jobGroupName)); } //創建定時任務調度 scheduler.scheduleJob(jobDetail, trigger); // 暫停任務 規定 0啟動 1暫停 if (job.getStatus().equals("1")) { scheduler.pauseJob(getJobKey(jobName, jobGroupName)); } } /** * 刪除定時調度任務 * * @param sysJob * @throws SchedulerException */ public void deleteScheduleJob(SysJob sysJob) throws SchedulerException { scheduler.deleteJob(getJobKey(sysJob.getJobId() + "_" + sysJob.getJobName(), sysJob.getJobGroupName())); } /** * 設置定時任務策略 * * @param sysJob * @param cronScheduleBuilder * @return */ 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("任務失敗策略 '" + sysJob.getMisfirePolicy() + "' 不能在cron計劃任務中使用", TaskException.Code.CONFIG_ERROR); } } }
創建一個Job實現類,只是一個簡單實現類,沒有對方法添加參數
@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("正在執行任務"); 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("已結束任務"); System.out.println(); } }
創建最終任務執行類,執行函數級別的定時任務,數據庫中的invoke_target是和這里放入spring中的名稱相同的,quartz_target.hello最終執行的函數就是hello函數
@Slf4j @Component("quartz_target") public class QuartzJobExe { @Resource private Scheduler scheduler; public void hello() throws Exception { System.out.println("[job]實例執行...hello..." + System.currentTimeMillis()); } public void action() throws Exception { System.out.println("[job]實例執行...action..." + System.currentTimeMillis()); } }
最終代碼結構
啟動spring boot之后的任務狀態
使用postman工具類添加一個任務
然后在代碼中添加一個對應的方法
重新啟動springboot的運行結果
