SpringBoot + Quartz 集成

Quartz

应用启动加载集群配置

• @Bean 注解交由 Spring BeanFactory 容器管理

  @Bean
  public JobDetailFactoryBean testJobDetailFactory() {
      JobDetailFactoryBean jobDetailFactory = new JobDetailFactoryBean();
      jobDetailFactory.setName("test-job");
      jobDetailFactory.setGroup("sns");
      jobDetailFactory.setJobClass(TestJob.class);
      jobDetailFactory.setDurability(true);
      return jobDetailFactory;
  }
  
  @Bean
  public CronTriggerFactoryBean testJobTrigger(
      @Qualifier("testJobDetailFactory") JobDetailFactoryBean factory) {
      CronTriggerFactoryBean tigger = new CronTriggerFactoryBean();
      if (factory.getObject() != null) {
          tigger.setJobDetail(factory.getObject());
      }
      tigger.setCronExpression("0/10 * * * * ?");
      tigger.setName("test-job-trigger");
      return tigger;
  }

  /**
   * SchedulerFactoryBean 实现 InitializingBean，
   * description: quartz定时任务配置
   */
  @Configuration
  public class QuartzConfig {
      private static final Logger LOGGER = LoggerFactory.getLogger(QuartzConfig.class);
      private static final String RESOURCE_NAME = "quartz.properties";
  
      @Resource
      private DataSource dataSource;
      @Autowired
      private SpringJobFactory springJobFactory;
  
      @Bean
      public SchedulerFactoryBean schedulerFactory(Trigger... triggers) {
          SchedulerFactoryBean factory = new SchedulerFactoryBean();
          Properties p = new Properties();
          try {
              p.load(this.getClass().getClassLoader().getResourceAsStream(RESOURCE_NAME));
          } catch (IOException e) {
              LOGGER.error("quartz定时任务加载{}过程中发生错误。");
              throw new Error(e);
          }
          factory.setQuartzProperties(p);
          factory.setDataSource(dataSource);
          factory.setOverwriteExistingJobs(true);
          factory.setStartupDelay(20);
          factory.setTriggers(triggers);
          factory.setJobFactory(springJobFactory);
          return factory;
      }
  }

• 实现 org.springframework.boot.CommandLineRunner ，应用启动成功后开启创建任务

  @Component
  public class InitScheduleOfAppStarted implements CommandLineRunner {
      private static final Logger LOGGER = LoggerFactory.getLogger(InitScheduleOfAppStarted.class);
  
      @Autowired
      private SysJobService sysJobService;
      // 任务 Bean 交由 Spring 管理，并注入任务所需的 Bean 实例
      @Autowired
      private SpringJobFactory springJobFactory;
  
      @Override
      public void run(String... args) throws Exception {
          Map<String, String> runJob = new HashMap();
          runJob.put("jobStatus", "1");
          List<SysJob> jobList = sysJobService.querySysJobList(runJob);
  
          if (null == jobList || jobList.size() <= 0) {
              LOGGER.info("app started，暂无需要执行的任务");
          }
  
          SchedulerFactory sf = new StdSchedulerFactory();
          Scheduler scheduler = sf.getScheduler();
          // 注入 spring 示例，否则执行时找不到 spring 容器中的 bean
          scheduler.setJobFactory(springJobFactory);
          scheduler.start();
  
          for (SysJob sysJob : jobList) {
  
              // jobDetail
              String jobName = sysJob.getJobName();
              String jobGroup = sysJob.getJobGroup();
              JobDetail jobDetail = JobBuilder.newJob(getClass(sysJob.getJobClassPath()).getClass())
                      .withIdentity(jobName, jobGroup)
                      .build();
              // jobTriller
              CronTrigger cronTrigger = TriggerBuilder.newTrigger()
                      .withIdentity(jobName, jobGroup)
                      .withSchedule(CronScheduleBuilder.cronSchedule(sysJob.getJobCron()))
                      .build();
              // 关联
              scheduler.scheduleJob(jobDetail, cronTrigger);
          }
      }
  
      private static Job getClass(String jobClassPath) throws Exception{
          Class<?> aClass = Class.forName(jobClassPath);
          return (Job) aClass.newInstance();
      }
  }

• 继承 org.springframework.scheduling.quartz.AdaptableJobFactory 实例化和依赖注入 Spring Bean 实例

  @Component
  public class SpringJobFactory extends AdaptableJobFactory {
  
      @Autowired
      private AutowireCapableBeanFactory capableBeanFactory;
  
      @Override
      protected Object createJobInstance(TriggerFiredBundle bundle) throws Exception {
          Object jobInstance = super.createJobInstance(bundle);
          capableBeanFactory.autowireBean(jobInstance);
          return jobInstance;
      }
  }
