1:去官網下載最新的 quartz 解壓 在目錄 docs\dbTables 下就會找到 tables_mysql.sql 文件、建立數據庫Quartz 并導入數據庫。
2、導入相應jar包
3、書寫QuartzConfig和InvokingJobDetailDetailFactory類
package com.example.demo.task;
import com.mchange.v2.c3p0.ComboPooledDataSource;
import org.quartz.JobDetail;
import org.quartz.Trigger;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.quartz.CronTriggerFactoryBean;
import org.springframework.scheduling.quartz.JobDetailFactoryBean;
import org.springframework.scheduling.quartz.SchedulerFactoryBean;
import java.beans.PropertyVetoException;
import java.io.IOException;
import java.util.HashMap;
import java.util.Map;
import java.util.Properties;
@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.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.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, PropertyVetoException {
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");
factory.setDataSource(createDataSource());
//注冊觸發器
factory.setTriggers(cronJobTrigger);//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, "*/5 * * * * ?");
}
@Bean
public ComboPooledDataSource createDataSource() throws PropertyVetoException {
ComboPooledDataSource dataSource = new ComboPooledDataSource();
dataSource.setDriverClass(myDSDriver);
dataSource.setJdbcUrl(myDSURL);
dataSource.setUser(myDSUser);
dataSource.setPassword(myDSPassword);
return dataSource;
}
/**
* 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;
}
}
package com.example.demo.task;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.context.ApplicationContext;
import org.springframework.scheduling.quartz.QuartzJobBean;
import java.lang.reflect.Method;
/**
* Created by Devin on 2017/7/2.
*/
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;
}
}
4、書寫相應的任務DialogJob
package com.example.demo.service;
import org.springframework.stereotype.Service;
/**
* Created by Devin on 2017/7/2.
*/
@Service("dialogJob")
public class DialogJob {
// 方法名在quartz定義
public void execute() throws Exception{
System.out.println("12345678");
}
}
5、寫配置文件application.properties
quartz.scheduler.instanceName=ServerScheduler
org.quartz.dataSource.myDS.driver=com.mysql.jdbc.Driver
org.quartz.dataSource.myDS.URL=jdbc:mysql://localhost:3306/quartz
org.quartz.dataSource.myDS.user=root
org.quartz.dataSource.myDS.password=root
org.quartz.dataSource.myDS.maxConnections=10
6、執行相應任務，集群環境下面配置多個項目，同一時間只有一個能啟動，別的會等待。
