SpringBoot自带定时器TimerTask

1.在启动类上加入注解@EnableScheduling

package cn.stylefeng.guns;

import cn.stylefeng.roses.core.config.WebAutoConfiguration;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableAsync;
import org.springframework.scheduling.annotation.EnableScheduling;

@EnableScheduling
@EnableAsync //开启异步调用
@SpringBootApplication(exclude = {WebAutoConfiguration.class})
public class GunsApplication {

    private final static Logger logger = LoggerFactory.getLogger(GunsApplication.class);

    public static void main(String[] args) {
        SpringApplication.run(GunsApplication.class, args);
        logger.info(GunsApplication.class.getSimpleName() + " is success!");
    }
}

2.定时任务，具体业务实现

package cn.stylefeng.guns.core.util;

import cn.stylefeng.guns.modular.airportManagement.basiclnfo.airportConfig.service.impl.RunwayTimeServiceImpl;
import org.springframework.scheduling.annotation.Async;
import org.springframework.scheduling.annotation.EnableAsync;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;
import org.springframework.transaction.interceptor.TransactionAspectSupport;

import javax.transaction.Transactional;
import java.util.List;
import java.util.TimerTask;

@Component
public class FlowTimer extends TimerTask {
    private FlowService flowService = (FlowService) ApplicationContextUtil.getBean("flowService");

    private RunwayTimeServiceImpl runwayTimeServiceImpl = (RunwayTimeServiceImpl) ApplicationContextUtil.getBean("runwayTimeServiceImpl");

    @Override
    @Async
    @Scheduled(fixedDelay = 90000) //每1分半钟执行一次
    public void run() {
 System.out.print("*****");
    }
}

3.配置类，将service实例化到定时器

package cn.stylefeng.guns.core.util;

import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.stereotype.Component;

@Component
public class ApplicationContextUtil implements ApplicationContextAware {
    private static ApplicationContext applicationContext;

    public static ApplicationContext getApplicationContext() {
        return applicationContext;
    }


    @Override
    public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
        ApplicationContextUtil.applicationContext = applicationContext;

    }


    public static Object getBean(String beanName) {
        return applicationContext.getBean(beanName);
    }



}
