SpringBoot整合Quartz

导入pom文件

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-quartz</artifactId>
        </dependency>

QuartzConfig

package com.pickle.config;
 
import com.pickle.quartz.MyQuartz;
import org.quartz.*;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
 
/**
 * @author Pickle
 * @version V1.0
 * @date 2024/3/14 11:42
 */
@Configuration
public class QuartzConfig {
    /**
     * 定义具体的工作明细
     * @return
     */
    @Bean
    public JobDetail printJobDetail(){
        //绑定具体的工作
        return JobBuilder.newJob(MyQuartz.class).storeDurably().build();
    }
 
    /**
     * 触发器
     * 绑定对应的工作明细
     * @return
     */
    @Bean
    public Trigger printTrigger(){
        //日期和星期一般不会同时规定
        //ToDo:cron表达式
        ScheduleBuilder<CronTrigger> scheduleBuilder = CronScheduleBuilder.cronSchedule("0/5 * * * * ?");
        return TriggerBuilder.newTrigger().forJob(printJobDetail()).withSchedule(scheduleBuilder).build();
    }
 
}
 

Spring简化Quartz

添加注解

编写任务

package com.pickle.demo;
 
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;
 
/**
 * @author Pickle
 * @version V1.0
 * @date 2024/3/14 11:57
 */
@Component
public class MyBean {
    @Scheduled(cron = "0/1 * * * * ?")
    public void  print(){
        System.out.println("Quartz task on..");
    }
}
