SpringBoot 自定义ThreadPoolTaskScheduler线程池执行定时任务

Posted 2022-08-19 张志翔 ̮

        最近项目中有使用到通过自定义线程池来执行定时任务操作的配置，特此记录便于日后查阅。

package com.xxx.iot.message.restapi.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.annotation.EnableScheduling;
import org.springframework.scheduling.annotation.SchedulingConfigurer;
import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;
import org.springframework.scheduling.concurrent.ThreadPoolTaskScheduler;
import org.springframework.scheduling.config.ScheduledTaskRegistrar;

import java.util.concurrent.ThreadPoolExecutor;

/**

@Configuration
@EnableScheduling
public class ThreadPoolConfig implements SchedulingConfigurer 

    /**
     * 定时任务使用的线程池
     * @return
     */
    @Bean(destroyMethod = "shutdown", name = "taskScheduler")
    public ThreadPoolTaskScheduler taskScheduler()
        ThreadPoolTaskScheduler scheduler = new ThreadPoolTaskScheduler();
        scheduler.setPoolSize(3);
        scheduler.setThreadNamePrefix("timer-thread");
        scheduler.setAwaitTerminationSeconds(600);
        scheduler.setWaitForTasksToCompleteOnShutdown(true);
        return scheduler;
    

    @Override
    public void configureTasks(ScheduledTaskRegistrar scheduledTaskRegistrar) 
        scheduledTaskRegistrar.setTaskScheduler(taskScheduler());
