1.创建一个springboot工程,选择依赖。
2.标注启动定时任务 @EnableScheduling 在启动类中
package com.lzx.demo01;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableScheduling;
@SpringBootApplication
@EnableScheduling
public class Demo01Application {
public static void main(String[] args) {
SpringApplication.run(Demo01Application.class, args);
}
}
3.创建我的定时任务类 @Scheduled 定义某个定时作业(或工作)
package com.lzx.demo01.Controller;
import lombok.extern.slf4j.Slf4j;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;
import java.util.Date;
/**
* @author 翔子
* @date ${date} ${time}
*/
@Component
public class Myjob {
@Scheduled(cron = "*/5 * * * * ?")
public void execute() {
System.out.print("任务正执行:" + new Date().toLocaleString());
}
}
4.配置 .yml文件
#默认使用配置
spring:
profiles:
active: dev
#公共配置与profiles选择无关 mapperLocations指的路径是src/main/resources
mybatis:
typeAliasesPackage: com.lzx.demo01
mapperLocations: classpath:mapper/*.xml
---
#开发配置
spring:
profiles: dev
datasource:
url: jdbc:mysql://localhost:3306/test
username: root
password: root
driver-class-name: com.mysql.jdbc.Driver
5.再看看pom.xml
