Spring Boot 定时任务

Spring Boot 定时任务

使用 注解 @Scheduled

package com.xxx.xxx;

import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;

/**
 * @author xxx
 */
@Slf4j
@Component
public class ScheduledTasks {

    // 创建线程池
    private ExecutorService service = Executors.newScheduledThreadPool(5);

    // 每隔 15 秒 执行一次
    private final String cron1= "0/15 * * * * ?";

    @Scheduled(cron = cron1)
    private void test1() {
        service.execute(() -> {
            log.info("定时任务");
            //假装这里有逻辑代码
        });
    }

}
