SchedulingConfigurer demo

@EnableScheduling 注解：

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

@SpringBootApplication
@EnableScheduling
public class ExterintellreceiveApplication {

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

注入ThreadPoolTaskScheduler：

package com.wilson;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.concurrent.ThreadPoolTaskScheduler;

@Configuration
public class ThreadPoolTaskSchedulerConfig {

    @Bean
    public ThreadPoolTaskScheduler threadPoolTaskScheduler() {
        ThreadPoolTaskScheduler executor = new ThreadPoolTaskScheduler();
        executor.setPoolSize(20);
        executor.setThreadNamePrefix("ThreadPoolTaskScheduler");
        executor.setWaitForTasksToCompleteOnShutdown(true);
        executor.setAwaitTerminationSeconds(60);
        return executor;
    }
}

定时任务：

package com.idss.exterintellreceive.scheduled;

import org.springframework.scheduling.annotation.SchedulingConfigurer;
import org.springframework.scheduling.config.ScheduledTaskRegistrar;
import org.springframework.stereotype.Component;

/**
 * @author admin
 */
@Component
public class TestScheduled implements SchedulingConfigurer {

    @Override
    public void configureTasks(ScheduledTaskRegistrar scheduledTaskRegistrar) {
        scheduledTaskRegistrar.addCronTask(() -> {
//            每隔一分钟打印一次 'hello world'
            System.out.println("hello world");
        }, "0 0/1 * * * ?");
    }
}
