5.spring boot schedule定时任务

1. spring boot的入口类Application.java中加入@EnableScheduling

package com.yunchuang;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableScheduling;
@SpringBootApplication
@EnableScheduling
public class Demo8Application {
    public static void main(String[] args) {
        SpringApplication.run(Demo8Application.class, args);
    }
}

2. 定时任务类

package com.yunchuang.schedule;
 
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;
 
import java.text.SimpleDateFormat;
import java.util.Date;
 
 
/**

@Component
public class Jobs {
 
    @Scheduled(fixedDelay = 1000)
    public void job1(){
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy年MM月dd日 HH时mm分ss秒");
        System.out.println(sdf.format(new Date()));
    }
    @Scheduled(cron = "0 10 3 ? * 1#3")
    public void job2(){
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy年MM月dd日 HH时mm分ss秒");
        System.out.println(sdf.format(new Date()));
    }
}
