配置

• 配置类

package com.example.test.configuration;


import com.example.test.service.IMiduService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.scheduling.annotation.SchedulingConfigurer;
import org.springframework.scheduling.config.ScheduledTaskRegistrar;

import java.util.concurrent.Executor;
import java.util.concurrent.Executors;
import java.util.concurrent.ScheduledExecutorService;

@Configuration
public class ScheduleConfig implements SchedulingConfigurer {

    @Autowired
    private IMiduService miduService;

    @Override
    public void configureTasks(ScheduledTaskRegistrar taskRegistrar) {
        taskRegistrar.setScheduler(taskExecutor());
    }

    @Bean(destroyMethod="shutdown")
    public Executor taskExecutor() {
        return Executors.newScheduledThreadPool(20);
    }

    @Scheduled(cron="0/3 * * * * *")
    public void get(){
        System.out.println("123");
    }

}

• 启动类上添加注解 @EnableScheduling
