使用quartz搭建调度中心

###quartz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 2.3.0

##思路

将quartz集成进spring boot,并且提供一下内容:

• 配置

• 样例作业和触发器

##实现

###1.配置

引入maven依赖(这里的quartz使用的是2.2.3)

<dependency>  <groupId>org.springframework</groupId>  <artifactId>spring-context-support</artifactId></dependency><dependency>  <groupId>org.quartz-scheduler</groupId>  <artifactId>quartz</artifactId>  <version>${quartz.version}</version></dependency>

编写AutowiringSpringBeanJobFactory类

public final class AutowiringSpringBeanJobFactory extends SpringBeanJobFactory    implements ApplicationContextAware {  /**   * 描述 : beanFactory   */  private AutowireCapableBeanFactory beanFactory;  @Override  public void setApplicationContext(final ApplicationContext context) {    beanFactory = context.getAutowireCapableBeanFactory();  }  @Override  protected Object createJobInstance(final TriggerFiredBundle bundle) throws Exception {    final Object job = super.createJobInstance(bundle);    beanFactory.autowireBean(job);    return job;  }}

编写SchedulerConfig类

@Configuration@ConfigurationProperties(prefix = "com.egridcloud.scheduler.config")@Validatedpublic class SchedulerConfig {..........}

编写SchedulerConfig类-属性

  //是否记录日志  @NotNull  private Boolean logFlag = true;  //是否记录详细日志  @NotNull  private Boolean logDetailFlag = false;  /是否自动启动  @NotNull  private Boolean autoStartup = true;  //是否覆盖已经存在的jobs  @NotNull  private Boolean overwriteExistingJobs = true;  //延迟启动秒数  @NotNull  private Integer startupDelay = 0;  /Job接受applicationContext的成员变量名  @NotNull  private String applicationContextSchedulerContextKey = "applicationContext";  //quartz配置文件地址  @NotNull  private String quartzPropertiesPath = "def_quartz.properties";

编写SchedulerConfig类-编写bean

  @Bean  public JobFactory jobFactory(ApplicationContext applicationContext) {    AutowiringSpringBeanJobFactory jobFactory = new AutowiringSpringBeanJobFactory();    jobFactory.setApplicationContext(applicationContext);    return jobFactory;  }    @Bean  public Properties quartzProperties() throws IOException {    PropertiesFactoryBean propertiesFactoryBean = new PropertiesFactoryBean();    propertiesFactoryBean.setLocation(new ClassPathResource(getQuartzPropertiesPath()));    propertiesFactoryBean.afterPropertiesSet();    return propertiesFactoryBean.getObject();  }    @Bean("clusterQuartzScheduler")  public SchedulerFactoryBean schedulerFactoryBean(DataSource dataSource, JobFactory jobFactory,      Properties quartzProperties)      throws IOException {    //实例化    SchedulerFactoryBean factory = new SchedulerFactoryBean();    factory.setDataSource(dataSource);    factory.setJobFactory(jobFactory);    //属性设置    factory.setQuartzProperties(quartzProperties);    factory.setOverwriteExistingJobs(getOverwriteExistingJobs());    factory.setAutoStartup(getAutoStartup());    factory.setStartupDelay(getStartupDelay());    factory.setApplicationContextSchedulerContextKey(getApplicationContextSchedulerContextKey());    //返回    return factory;  }

编写def_quartz.properties配置文件

#Configure schedulerorg.quartz.scheduler.instanceName=clusterQuartzSchedulerorg.quartz.scheduler.instanceId=AUTOorg.quartz.scheduler.skipUpdateCheck=true#Configure ThreadPoolorg.quartz.threadPool.class=org.quartz.simpl.SimpleThreadPoolorg.quartz.threadPool.threadCount=5org.quartz.threadPool.threadPriority=5#Configure JobStore and Clusterorg.quartz.jobStore.class=org.quartz.impl.jdbcjobstore.JobStoreTXorg.quartz.jobStore.driverDelegateClass=org.quartz.impl.jdbcjobstore.StdJDBCDelegateorg.quartz.jobStore.useProperties=trueorg.quartz.jobStore.tablePrefix=QRTZ_org.quartz.jobStore.isClustered=trueorg.quartz.jobStore.clusterCheckinInterval=20000org.quartz.jobStore.misfireThreshold=60000

执行数据库脚本,以及数据库配置(按需,我这里选择的是h2)

tables_h2.sql###########################################################DATASOURCE (DataSourceAutoConfiguration & DataSourceProperties)########################################################spring.datasource.url=jdbc:h2:file:D:/develop/d2_db/testdb
