使用awaitility包进行Scheduling Task

 

依赖：

Later versions of the awaitility library do not work for this test, so you have to specify version 3.1.2.

<dependency>
    <groupId>org.awaitility</groupId>
    <artifactId>awaitility</artifactId>
    <version>3.1.2</version>
    <scope>test</scope>
</dependency>

package com.springboot;

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;

@Component
public class ScheduleTask {

    public static final Logger logger = LoggerFactory.getLogger(ScheduleTask.class);
    public static final SimpleDateFormat sdf =
            new SimpleDateFormat("一年中的第D天-第F个E-yyyy-MM-dd-HH:mm:ss");

    //固定每5s刷新一次
    @Scheduled(fixedRate = 5000L)
    public void currentTime(){
        //{}：占位符
        logger.info("现在时间是 {}",sdf.format(new Date()));
    }
}

 

需要在主类中使用@EnableScheduling开启

package com.springboot;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableScheduling;

@SpringBootApplication
@EnableScheduling
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

}

 

　　运行效果：
