Quarzt整合springBoot

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

项目结构

 主类：

package com.example.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableScheduling;

@SpringBootApplication
@EnableScheduling //开启Scheduling支持
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }
}

简单方法的实现
package com.example.demo.quartz;

import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.annotation.Scheduled;

import java.util.Date;

/**
 * @author zm
 * @version 1.0
 * @date 2021/4/25 15:14
 */
@Configuration
public class SimpleJob {

    @Scheduled(cron = "0/1 * * * * ?")
    public void run() {
        System.out.println(new Date());
    }
}

这个类可以定义一些业务复杂的定时任务

package com.example.demo.quartz;

import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.Trigger;
import org.springframework.scheduling.TriggerContext;
import org.springframework.scheduling.annotation.SchedulingConfigurer;
import org.springframework.scheduling.config.ScheduledTaskRegistrar;
import org.springframework.scheduling.support.CronTrigger;

import java.util.Date;

/**
 * @author zm
 * @version 1.0
 * @date 2021/4/25 15:38
 */
@Configuration
public class ComplexJob implements SchedulingConfigurer {

    @Override
    public void configureTasks(ScheduledTaskRegistrar scheduledTaskRegistrar) {
        scheduledTaskRegistrar.addTriggerTask(new Runnable() {
            @Override
            public void run() {
                System.err.println(new Date());
            }
        }, new Trigger() {
            @Override
            public Date nextExecutionTime(TriggerContext triggerContext) {
                return new CronTrigger("0/2 * * * * ?").nextExecutionTime(triggerContext);
            }
        });

    }
}
