ScheduledConfig.java

@Configuration
public class ScheduledConfig implements SchedulingConfigurer {
	
	
	@Value("${scheduled-thread-pool}")
	private int scheduledThreadPool;

	@Override
	public void configureTasks(ScheduledTaskRegistrar scheduledTaskRegistrar) {
		scheduledTaskRegistrar.setScheduler(setTaskExecutors());
	}
//
	@Bean(destroyMethod = "shutdown")
	public Executor setTaskExecutors() {
		return Executors.newScheduledThreadPool(scheduledThreadPool); // scheduledThreadPool個線程來處理。
	}

具體執(zhí)行的任務(wù)：

ScheduledDeleteData.java

import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;

import com.pub.cloud.system.status.util.H2Util;




@Component
public class ScheduledDeleteData {
	private static final Logger logger = LogManager.getLogger(ScheduledDeleteData.class);

	@Value("${source-url}")
	private String sourceUrl;
	
	//時間間隔
	@Scheduled(fixedRate = 60000)
	public void scheduledExcSql() {
		System.out.println(sourceUrl);
	}

}

application.yml配置文件

scheduled-thread-pool: 1
source-url : "*****************"

SpringApplication.run中加如注解

@EnableScheduling

LinuxSystemStatusApplication.java

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

@SpringBootApplication
@EnableScheduling
public class LinuxSystemStatusApplication {

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