spring 定时任务 使用线程池

spring 线程池定义

package com.minex.icp.tool.conf;

import lombok.extern.slf4j.Slf4j;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.annotation.AsyncConfigurerSupport;
import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;

@Slf4j
@Configuration
public class ScheduledThreadPoolConfig extends AsyncConfigurerSupport {
    /**
     * Scheduled executor
     *
     * @return the executor
     * @since 3.2.0
     */
    @Bean
    public Executor taskManagerExecutor() {
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        executor.setCorePoolSize(3);
        executor.setMaxPoolSize(5);
        executor.setQueueCapacity(10);
        executor.setThreadNamePrefix("taskManager-");
        executor.setKeepAliveSeconds(60);
        executor.setRejectedExecutionHandler(new ThreadPoolExecutor.AbortPolicy());
        return executor;
    }
}

 

使用方式： @Async 

/**
     * 电网负荷统计任务 (每 90 秒查询一次)
     *
     * @since 3.0.0
     */
    @Async("taskManagerExecutor")
    @Scheduled(cron = "30 0/1 * * * ?")
    public void gridLoadJob() {
        log.debug("gridLoadJob::begin");
        homePageService.gridLoadQuery("", "xf", false);
        homePageService.gridLoadQuery("", "zyxc", false);
        log.debug("gridLoadJob::end");
    }
