1. 导入依赖

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

2. 任务类

package com.demo.quartz;

import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;
import java.util.Date;

@Component
public class MyQuartz {
    @Scheduled(cron="*/2 * * * * ? ") // 每隔 2s 执行一次
    public void testQuartz(){
        System.out.println("testQuartz："+new Date().toLocaleString());
    }
}

3. @EnableScheduling

在启动类添加 @EnableScheduling 配置，然后直接启动测试。

package com.demo;

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

@SpringBootApplication
@EnableScheduling
public class Springboot02Application {
    public static void main(String[] args) {
        SpringApplication.run(Springboot02Application.class, args);
    }
}
