spring boot 任務排程
1.依賴檔案
檔名:pom.xml
檔案內容:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

2.業務類
包名：com.huinong.springboot.hello
類名：ScheduledTasks
類內容：
package com.huinong.springboot.hello;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;
import java.text.SimpleDateFormat;
import java.util.Date;
/**
* Created by dengdashuai on 2018/12/6.
*/
@Component
public class ScheduledTasks {
private static final Logger log = LoggerFactory.getLogger(ScheduledTasks.class);
private static final SimpleDateFormat dateFormat = new SimpleDateFormat("HH:mm:ss");
// 5秒執行一次該方法
@Scheduled(fixedRate = 5000)
public void reportCurrentTime(){
log.info("The time is now {}", dateFormat.format(new Date()));
}
}
3.應用入口檔案
包名：com.huinong.springboot.hello
類名：Application
類內容：
package com.huinong.springboot.hello;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableScheduling;
/**
* Created by dengdashuai on 2018/12/6.
*/
@SpringBootApplication
// 開啟任務排程
@EnableScheduling
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class);
}
}
