SpringBoot-Task定時器

項目中,許多地方都會用到定時器的功能, SpringBoot中也是有定時器的:

1:  建立定時工具類:

package com.gy.demo.common.config.task;

import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;

import java.text.SimpleDateFormat;
import java.util.Date;

/**
 * Description: 定時任務實現類
 * 註釋: @Scheduled 定時器執行規則: @Scheduled(fixedRate = 6000) : 6秒執行一次
 * @author geYang
 * @since 2017/12/26
 **/
@Component
public class SchedulerTask {
	private static final SimpleDateFormat dateFormat = new SimpleDateFormat("HH:mm:ss");
	
	@Scheduled(fixedRate = 6000)
	public void reportCurrentTime() {
		System.out.println("如今時間：" + dateFormat.format(new Date()));
	}

}

2: 使用時在啓動類中聲明:

package com.gy.demo;

import org.mybatis.spring.annotation.MapperScan;
import org.slf4j.LoggerFactory;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableScheduling;

/**
 * 項目啓動類
 * 註解: @EnableScheduling 啓動項目時開啓定時任務
 *
 * @author geYang
 */
@EnableScheduling
@SpringBootApplication
public class DemoApplication {
	private  static org.slf4j.Logger logger = LoggerFactory.getLogger(DemoApplication.class);
	public static void main(String[] args) {
		SpringApplication.run(DemoApplication.class, args);
		logger.info("項目啓動成功!");
	}
}
