1. 獲取 sql 腳本文件，創建數據庫
在官網下載好包后，在 quartz-2.3.0-SNAPSHOT\src\org\quartz\impl\jdbcjobstore 目錄下可以選擇適合自己的數據庫腳本文件
我使用的數據庫是mysql,因此我也將sql腳本放到了本項目的 resources 目錄下

2. 創建springboot項目，導入maven依賴包
<dependency>
<groupId>com.mchange</groupId>
<artifactId>c3p0</artifactId>
<version>0.9.5.4</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-quartz</artifactId>
<version>2.3.3.RELEASE</version>
</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<scope>runtime</scope>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-jdbc</artifactId>
</dependency>
3. 在 resources 目錄下創建 quartz 的配置文件 quartz.properties
#quartz集群配置
# ===========================================================================
# Configure Main Scheduler Properties 調度器屬性
# ===========================================================================
#調度標識名 集群中每一個實例都必須使用相同的名稱
org.quartz.scheduler.instanceName=DefaultQuartzScheduler
#ID設置為自動獲取 每一個必須不同
org.quartz.scheduler.instanceid=AUTO
#============================================================================
# Configure ThreadPool
#============================================================================
#線程池的實現類（一般使用SimpleThreadPool即可滿足幾乎所有用戶的需求）
org.quartz.threadPool.class=org.quartz.simpl.SimpleThreadPool
#指定線程數，至少為1（無默認值）(一般設置為1-100直接的整數合適)
org.quartz.threadPool.threadCount=25
#設置線程的優先級（最大為java.lang.Thread.MAX_PRIORITY 10，最小為Thread.MIN_PRIORITY 1，默認為5）
org.quartz.threadPool.threadPriority=5
#============================================================================
# Configure JobStore
#============================================================================
# 信息保存時間 默認值60秒
org.quartz.jobStore.misfireThreshold=60000
#數據保存方式為數據庫持久化
org.quartz.jobStore.class=org.quartz.impl.jdbcjobstore.JobStoreTX
#數據庫代理類，一般org.quartz.impl.jdbcjobstore.StdJDBCDelegate可以滿足大部分數據庫
org.quartz.jobStore.driverDelegateClass=org.quartz.impl.jdbcjobstore.StdJDBCDelegate
#JobDataMaps是否都為String類型
org.quartz.jobStore.useProperties=false
#數據庫別名 隨便取
org.quartz.jobStore.dataSource=myDS
#表的前綴，默認QRTZ_
org.quartz.jobStore.tablePrefix=QRTZ_
#是否加入集群
org.quartz.jobStore.isClustered=true
#調度實例失效的檢查時間間隔
org.quartz.jobStore.clusterCheckinInterval=20000
#============================================================================
# Configure Datasources
#============================================================================
#數據庫引擎
org.quartz.dataSource.myDS.driver=com.mysql.cj.jdbc.Driver
#數據庫連接
org.quartz.dataSource.myDS.URL=jdbc:mysql://localhost:3306/quartz?characterEncoding=utf8&allowMultiQueries=true&useSSL=false&autoReconnect=true&serverTimezone=UTC
#數據庫用戶
org.quartz.dataSource.myDS.user=root
#數據庫密碼
org.quartz.dataSource.myDS.password=root
#允許最大連接
org.quartz.dataSource.myDS.maxConnections=5
#驗證查詢sql,可以不設置
org.quartz.dataSource.myDS.validationQuery=select 0 from dual
4. 注冊Quartz任務工廠（TaskJobFactory）
@Component
public class TaskJobFactory extends AdaptableJobFactory {
@Autowired
AutowireCapableBeanFactory capableBeanFactory;
@Override
protected Object createJobInstance(TriggerFiredBundle bundle) throws Exception {
//調用父類的方法
Object jobInstance = super.createJobInstance(bundle);
//進行注入
capableBeanFactory.autowireBean(jobInstance);
return jobInstance;
}
}
5. 注冊調度工廠，以及生成調度實例
若要在該服務啟動時，就執行調度任務，需要將 factory.setAutoStartup(false); 改為 factory.setAutoStartup(true);
@Configuration
public class QuartzConfig {
@Autowired
DataSource dataSource;
@Autowired
TaskJobFactory jobFactory;
@Bean(name = "SchedulerFactory")
public SchedulerFactoryBean schedulerFactoryBean() throws IOException {
//獲取配置屬性
PropertiesFactoryBean propertiesFactoryBean = new PropertiesFactoryBean();
propertiesFactoryBean.setLocation(new ClassPathResource("/quartz.properties"));
//在quartz.properties中的屬性被讀取並注入后再初始化對象
propertiesFactoryBean.afterPropertiesSet();
//創建SchedulerFactoryBean
SchedulerFactoryBean factory = new SchedulerFactoryBean();
//將配置文件中的信息添加到調度工廠中
//對應java應用程序中的 new StdSchedulerFactory(properties)
factory.setQuartzProperties(propertiesFactoryBean.getObject());
factory.setJobFactory(jobFactory);
// 默認的自動執行調度,這里設置為不自動執行調度，
// 為了方便擴展集群分布式調度任務，這個服務只配置調度，另外啟動一個或多個服務執行調度
factory.setAutoStartup(false);
return factory;
}
/*
* 通過SchedulerFactoryBean獲取Scheduler的實例
*/
@Bean(name = "scheduler")
public Scheduler scheduler() throws IOException, SchedulerException {
Scheduler scheduler = schedulerFactoryBean().getScheduler();
return scheduler;
}
}
6. Quartz服務層接口（QuartzService）
public interface QuartzService {
/**
* 添加任務可以傳參數
*
* @param clazz
* @param jobName
* @param groupName
* @param cronExp
* @param param
*/
void addJob(Class clazz, String jobName, String groupName, String cronExp, Map<String, Object> param);
/**
* 暫停任務
*
* @param name
* @param groupName
*/
void pauseJob(String name, String groupName);
/**
* 恢復任務
*
* @param name
* @param groupName
*/
void resumeJob(String name, String groupName);
/**
* 更新任務
*
* @param name
* @param groupName
* @param cronExp
* @param param
*/
void updateJob(String name, String groupName, String cronExp, Map<String, Object> param);
/**
* 刪除任務
*
* @param name
* @param groupName
*/
void deleteJob(String name, String groupName);
/**
* 啟動所有任務
*/
void startAllJobs();
/**
* 關閉所有任務
*/
void shutdownAllJobs();
}
7. 任務調度服務接口實現類（QuartzServiceImpl）
@Service
public class QuartzServiceImpl implements QuartzService {
@Autowired
Scheduler scheduler;
/**
* 創建job，可傳參
*
* @param clazz 任務類
* @param name 任務名稱
* @param groupName 任務所在組名稱
* @param cronExp cron表達式
* @param param map形式參數
*/
@Override
public void addJob(Class clazz, String name, String groupName, String cronExp, Map<String, Object> param) {
try {
// 啟動調度器
// scheduler.start();
//構建job信息
//((Job) clazz.newInstance()).getClass()
JobDetail jobDetail = JobBuilder.newJob(clazz).withIdentity(name, groupName).build();
//表達式調度構建器(即任務執行的時間)
CronScheduleBuilder scheduleBuilder = CronScheduleBuilder.cronSchedule(cronExp);
//按新的cronExpression表達式構建一個新的trigger
CronTrigger trigger = TriggerBuilder.newTrigger().withIdentity(name, groupName).withSchedule(scheduleBuilder).build();
//獲得JobDataMap，寫入數據
if (param != null) {
trigger.getJobDataMap().putAll(param);
}
scheduler.scheduleJob(jobDetail, trigger);
} catch (Exception e) {
e.printStackTrace();
}
}
/**
* 暫停job
*
* @param name 任務名稱
* @param groupName 任務所在組名稱
*/
@Override
public void pauseJob(String name, String groupName) {
try {
scheduler.pauseJob(JobKey.jobKey(name, groupName));
} catch (SchedulerException e) {
e.printStackTrace();
}
}
/**
* 恢復job
*
* @param name 任務名稱
* @param groupName 任務所在組名稱
*/
@Override
public void resumeJob(String name, String groupName) {
try {
scheduler.resumeJob(JobKey.jobKey(name, groupName));
} catch (SchedulerException e) {
e.printStackTrace();
}
}
/**
* job 更新,更新頻率和參數
*
* @param name 任務名稱
* @param groupName 任務所在組名稱
* @param cronExp cron表達式
* @param param 參數
*/
@Override
public void updateJob(String name, String groupName, String cronExp, Map<String, Object> param) {
try {
TriggerKey triggerKey = TriggerKey.triggerKey(name, groupName);
CronTrigger trigger = (CronTrigger) scheduler.getTrigger(triggerKey);
if (cronExp != null) {
// 表達式調度構建器
CronScheduleBuilder scheduleBuilder = CronScheduleBuilder.cronSchedule(cronExp);
// 按新的cronExpression表達式重新構建trigger
trigger = trigger.getTriggerBuilder().withIdentity(triggerKey).withSchedule(scheduleBuilder).build();
}
//修改map
if (param != null) {
trigger.getJobDataMap().putAll(param);
}
// 按新的trigger重新設置job執行
scheduler.rescheduleJob(triggerKey, trigger);
} catch (Exception e) {
e.printStackTrace();
}
}
/**
* job 刪除
* <p>
* 同時刪除 調度中的觸發器 Trigger 和任務 job
*
* @param name 任務名稱
* @param groupName 任務所在組名稱
*/
@Override
public void deleteJob(String name, String groupName) {
try {
scheduler.pauseTrigger(TriggerKey.triggerKey(name, groupName));
scheduler.unscheduleJob(TriggerKey.triggerKey(name, groupName));
scheduler.deleteJob(JobKey.jobKey(name, groupName));
} catch (Exception e) {
e.printStackTrace();
}
}
/**
* 啟動所有定時任務
*/
@Override
public void startAllJobs() {
try {
scheduler.start();
} catch (Exception e) {
throw new RuntimeException(e);
}
}
/**
* 關閉所有定時任務
*/
@Override
public void shutdownAllJobs() {
try {
if (!scheduler.isShutdown()) {
// scheduler生命周期結束，無法再 start() 啟動
scheduler.shutdown();
}
} catch (Exception e) {
throw new RuntimeException(e);
}
}
}
8. 需要執行的任務（OrderTimeOutJob ）
public class OrderTimeOutJob implements Job {
@Override
public void execute(JobExecutionContext context) {
//獲取任務名
String taskName = context.getJobDetail().getKey().getName();
String groupName=context.getJobDetail().getKey().getGroup();
System.out.println(String.format("task--->%s,%s",taskName,groupName));
//todo:處理執行任務時的業務代碼
}
}
9. 編寫接口類進行測試（JobController）
@RestController
public class JobController {
@Autowired
QuartzService service;
/**
* 添加新任務
*
* @return
*/
@RequestMapping("/addJob")
public Object addJob(@RequestParam String groupName, @RequestParam String jobName) {
Map<String, Object> resultMap = new HashMap<>();
//任務組名
// String groupName = "order3";
//任務名
// String jobName = "20190724120322389224";
//CRON表達式
String cronExp = "* * * * * ? *";
service.addJob(OrderTimeOutJob.class, jobName, groupName, cronExp, null);
resultMap.put("groupName", groupName);
resultMap.put("jobName", jobName);
resultMap.put("cronExp", cronExp);
return resultMap;
}
/**
* 啟動調度
*
* @return
*/
@RequestMapping("/startAllJobs")
public String startAllJobs() {
service.startAllJobs();
return "true";
}
/**
* 關閉調度
*
* @return
*/
@RequestMapping("/shutdownAllJobs")
public String shutdownAllJobs() {
service.shutdownAllJobs();
return "true";
}
/**
* 暫停某個調度
*
* @param groupName
* @param jobName
* @return
*/
@RequestMapping("/pauseJob")
public String pauseJob(@RequestParam String groupName, @RequestParam String jobName) {
service.pauseJob(jobName, groupName);
return "true";
}
/**
* 恢復調度某個暫停的任務
*
* @param groupName
* @param jobName
* @return
*/
@RequestMapping("/resumeJob")
public String resumeJob(@RequestParam String groupName, @RequestParam String jobName) {
service.resumeJob(jobName, groupName);
return "true";
}
/**
* 刪除任務
*
* @return
*/
@RequestMapping("/delJob")
public Object delJob(@RequestParam String groupName, @RequestParam String jobName) {
Map<String, Object> resultMap = new HashMap<>();
//任務組名
//任務名
service.deleteJob(jobName, groupName);
resultMap.put("groupName", groupName);
resultMap.put("jobName", jobName);
return resultMap;
}
}
10. 最后添加配置文件 application.yml,啟動項目
spring:
application:
name: quartz
datasource:
url: jdbc:mysql://localhost:3306/quartz?characterEncoding=utf8&allowMultiQueries=true&useSSL=false&autoReconnect=true&serverTimezone=UTC
username: root
password: root
總結
- 若需要隨着上面項目的啟動，就執行調度任務，需要將步驟5中
factory.setAutoStartup(false);改為factory.setAutoStartup(true);，或者直接刪除factory.setAutoStartup(false); - 為了保證調度的高可用，重新創建一個或多個新項目用來執行調度，新項目中只需要配置上面的
2~5步驟即可
，第五步將factory.setAutoStartup(false);改為factory.setAutoStartup(true);，或者直接刪除factory.setAutoStartup(false);
