pom依赖

<dependency><groupId>org.quartz-scheduler</groupId><artifactId>quartz</artifactId><version>2.2.1</version>
</dependency>

import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;/*** @author hrui* @date 2023/11/17 0:52*/
public class MyJob implements Job {@Overridepublic void execute(JobExecutionContext context) throws JobExecutionException {//Object user = context.getJobDetail().getJobDataMap().get("user");Object user = context.getTrigger().getJobDataMap().get("user");System.out.println(user+"在执行任务");}
}

import org.quartz.*;

public class Test {public static void main(String[] args) throws SchedulerException {Scheduler scheduler= StdSchedulerFactory.getDefaultScheduler();JobDetail jobDetail= JobBuilder.newJob(MyJob.class).withIdentity("job1", "group1").build();Trigger trigger=TriggerBuilder.newTrigger().withIdentity("trg1", "tg1").usingJobData("user", "用户1").withSchedule(CronScheduleBuilder.cronSchedule("*/2 * * * * ?")).build();scheduler.scheduleJob(jobDetail, trigger);scheduler.start();try {Thread.sleep(5000);} catch (InterruptedException e) {e.printStackTrace();}Trigger newTrigger = TriggerBuilder.newTrigger().withIdentity("newTrigger", "tg1").startNow().usingJobData("user", "用户2").withSchedule(CronScheduleBuilder.cronSchedule("*/3 * * * * ?")).build();// 替换原始触发器 替换之后,原来的触发器会被删除scheduler.rescheduleJob(trigger.getKey(), newTrigger);Trigger trigger1 = scheduler.getTrigger(trigger.getKey());System.out.println(trigger1);Trigger trigger2 = scheduler.getTrigger(newTrigger.getKey());System.out.println(trigger2);}
}

执行结果

解决日志问题

引入日志依赖 pom文件

<dependencies><dependency><groupId>org.quartz-scheduler</groupId><artifactId>quartz</artifactId><version>2.2.1</version></dependency><!--log4j--><dependency><groupId>org.slf4j</groupId><artifactId>slf4j-log4j12</artifactId><version>1.7.12</version></dependency><dependency><groupId>log4j</groupId><artifactId>log4j</artifactId><version>1.2.17</version></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><version>RELEASE</version><scope>compile</scope></dependency></dependencies>

resources下新建 log4j.properties文件

# 设置日志级别为INFO
log4j.rootCategory=INFO, stdout# 输出到控制台的appender配置
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n# 输出到文件的appender配置
log4j.appender.file=org.apache.log4j.RollingFileAppender
#log4j.appender.file.File=/path/to/quartz.log
log4j.appender.file.File=F:/quartz.log
log4j.appender.file.MaxFileSize=10MB
log4j.appender.file.MaxBackupIndex=5
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n# 配置quartz的日志级别为INFO，并将日志输出到控制台和文件
log4j.logger.org.quartz=INFO, stdout, file
