quartz集群能力：
以上是個人的一些見解，下面開始本文的正文，本文主要介紹了關于spring boot + quartz集群搭建的相關內容，分享出來供大家參考學習，下面話不多說了，來一起看看詳細的介紹吧。
步驟如下：
spring boot bean配置：
@Configuration
public class QuartzConfig {
@Value("${quartz.scheduler.instanceName}")
private String quartzInstanceName;
@Value("${org.quartz.dataSource.myDS.driver}")
private String myDSDriver;
@Value("${org.quartz.dataSource.myDS.URL}")
private String myDSURL;
@Value("${org.quartz.dataSource.myDS.user}")
private String myDSUser;
@Value("${org.quartz.dataSource.myDS.password}")
private String myDSPassword;
@Value("${org.quartz.dataSource.myDS.maxConnections}")
private String myDSMaxConnections;
/**
* 設置屬性
* @return
* @throws IOException
*/
private Properties quartzProperties() throws IOException {
Properties prop = new Properties();
prop.put("quartz.scheduler.instanceName", quartzInstanceName);
prop.put("org.quartz.scheduler.instanceId", "AUTO");
prop.put("org.quartz.scheduler.skipUpdateCheck", "true");
prop.put("org.quartz.scheduler.jmx.export", "true");
prop.put("org.quartz.jobStore.class", "org.quartz.impl.jdbcjobstore.JobStoreTX");
prop.put("org.quartz.jobStore.driverDelegateClass", "org.quartz.impl.jdbcjobstore.StdJDBCDelegate");
prop.put("org.quartz.jobStore.dataSource", "quartzDataSource");
prop.put("org.quartz.jobStore.tablePrefix", "QRTZ_");
prop.put("org.quartz.jobStore.isClustered", "true");
prop.put("org.quartz.jobStore.clusterCheckinInterval", "20000");
prop.put("org.quartz.jobStore.dataSource", "myDS");
prop.put("org.quartz.jobStore.maxMisfiresToHandleAtATime", "1");
prop.put("org.quartz.jobStore.misfireThreshold", "120000");
prop.put("org.quartz.jobStore.txIsolationLevelSerializable", "true");
prop.put("org.quartz.jobStore.selectWithLockSQL", "SELECT * FROM {0}LOCKS WHERE LOCK_NAME = ? FOR UPDATE");
prop.put("org.quartz.threadPool.class", "org.quartz.simpl.SimpleThreadPool");
prop.put("org.quartz.threadPool.threadCount", "10");
prop.put("org.quartz.threadPool.threadPriority", "5");
prop.put("org.quartz.threadPool.threadsInheritContextClassLoaderOfInitializingThread", "true");
prop.put("org.quartz.dataSource.myDS.driver", myDSDriver);
prop.put("org.quartz.dataSource.myDS.URL", myDSURL);
prop.put("org.quartz.dataSource.myDS.user", myDSUser);
prop.put("org.quartz.dataSource.myDS.password", myDSPassword);
System.out.println("myDSMaxConnections:" + myDSMaxConnections);
prop.put("org.quartz.dataSource.myDS.maxConnections", myDSMaxConnections);
prop.put("org.quartz.plugin.triggHistory.class", "org.quartz.plugins.history.LoggingJobHistoryPlugin");
prop.put("org.quartz.plugin.shutdownhook.class", "org.quartz.plugins.management.ShutdownHookPlugin");
prop.put("org.quartz.plugin.shutdownhook.cleanShutdown", "true");
return prop;
}
@Bean
public SchedulerFactoryBean schedulerFactoryBean(@Qualifier("dialogJobTrigger") Trigger cronJobTrigger) throws IOException {
SchedulerFactoryBean factory = new SchedulerFactoryBean();
// this allows to update triggers in DB when updating settings in config file:
//用于quartz集群,QuartzScheduler 啟動時更新己存在的Job，這樣就不用每次修改targetObject后刪除qrtz_job_details表對應記錄了
factory.setOverwriteExistingJobs(true);
//用于quartz集群,加載quartz數據源
//factory.setDataSource(dataSource);
//QuartzScheduler 延時啟動，應用啟動完10秒后 QuartzScheduler 再啟動
factory.setStartupDelay(10);
//用于quartz集群,加載quartz數據源配置
factory.setQuartzProperties(quartzProperties());
factory.setAutoStartup(true);
factory.setApplicationContextSchedulerContextKey("applicationContext");
//注冊觸發器
factory.setTriggers(cronJobTrigger);<br data-filtered="filtered"> //直接使用配置文件
// factory.setConfigLocation(new FileSystemResource(this.getClass().getResource("/quartz.properties").getPath()));
return factory;
}
/**
* 加載job
* @return
*/
@Bean
public JobDetailFactoryBean updateDialogStatusJobDetail() {
return createJobDetail(InvokingJobDetailDetailFactory.class, "updateDialogStatusGroup", "dialogJob");
}
/**
* 加載觸發器
* @param jobDetail
* @return
*/
@Bean(name = "dialogJobTrigger")
public CronTriggerFactoryBean dialogStatusJobTrigger(@Qualifier("updateDialogStatusJobDetail") JobDetail jobDetail) {
return dialogStatusTrigger(jobDetail, "0 0 0/1 * * ?");
}
/**
* 創建job工廠
* @param jobClass
* @param groupName
* @param targetObject
* @return
*/
private static JobDetailFactoryBean createJobDetail(Class<?> jobClass, String groupName, String targetObject) {
JobDetailFactoryBean factoryBean = new JobDetailFactoryBean();
factoryBean.setJobClass(jobClass);
factoryBean.setDurability(true);
factoryBean.setRequestsRecovery(true);
factoryBean.setGroup(groupName);
Map<String, String> map = new HashMap<>();
map.put("targetObject", targetObject);
map.put("targetMethod", "execute");
factoryBean.setJobDataAsMap(map);
return factoryBean;
}
/**
* 創建觸發器工廠
* @param jobDetail
* @param cronExpression
* @return
*/
private static CronTriggerFactoryBean dialogStatusTrigger(JobDetail jobDetail, String cronExpression) {
CronTriggerFactoryBean factoryBean = new CronTriggerFactoryBean();
factoryBean.setJobDetail(jobDetail);
factoryBean.setCronExpression (cronExpression);
return factoryBean;
}
}
InvokingJobDetailDetailFactory對象：
public class InvokingJobDetailDetailFactory extends QuartzJobBean{
// 計劃任務所在類
private String targetObject;
// 具體需要執行的計劃任務
private String targetMethod;
private ApplicationContext ctx;
@Override
protected void executeInternal(JobExecutionContext context) throws JobExecutionException {
try {
Object otargetObject = ctx.getBean(targetObject);
Method m = null;
try {
m = otargetObject.getClass().getMethod(targetMethod);
m.invoke(otargetObject);
} catch (SecurityException e) {
e.printStackTrace();
} catch (NoSuchMethodException e) {
e.printStackTrace();
}
} catch (Exception e) {
throw new JobExecutionException(e);
}
}
public void setApplicationContext(ApplicationContext applicationContext) {
this.ctx = applicationContext;
}
public void setTargetObject(String targetObject) {
this.targetObject = targetObject;
}
public void setTargetMethod(String targetMethod) {
this.targetMethod = targetMethod;
}
}
備注：set方法不能少，setApplicationContext中的applicationContext與factory.setApplicationContextSchedulerContextKey("applicationContext")填入的值有關，其原理由InvokingJobDetailDetailFactory父類中的BeanWrapper實現。

quartz集群實現原理，利用數據庫記錄job行為，并通過鎖機制，使job在同一次中僅運行一次。
JobBean示例
//需要交由spring管理
@Service("dialogJob")
public class DialogJob {
@Autowired
private QuestionService questionService;
// 方法名在quartz定義
public void execute() throws Exception{
//具體執行業務
questionService.XXXXX();
}
}
