springboot 异步调用

1，定义异步config

package com.text.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.scheduling.annotation.AsyncConfigurer;
import org.springframework.scheduling.annotation.EnableAsync;
import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;

import java.util.concurrent.ThreadPoolExecutor;

/**
* @author zys on 2022-03-26
*/
@Configuration
@EnableAsync
public class AsyncConfig implements AsyncConfigurer {

    /** 核心线程数（默认线程数） */
    private static final int corePoolSize = 10;
    /** 最大线程数 */
    private static final int maxPoolSize = 20;
    /** 允许线程空闲时间（单位：默认为秒） */
    private static final int keepAliveTime = 10;
    /** 缓冲队列大小 */
    private static final int queueCapacity = 50;
    /** 线程池名前缀 */
    private static final String threadNamePrefix = "Async-Statistics-";

    @Bean("taskExecutor")
    public ThreadPoolTaskExecutor taskExecutor(){
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        executor.setCorePoolSize(corePoolSize);
        executor.setMaxPoolSize(maxPoolSize);
        executor.setQueueCapacity(queueCapacity);
        executor.setKeepAliveSeconds(keepAliveTime);
        executor.setThreadNamePrefix(threadNamePrefix);
        executor.setRejectedExecutionHandler(new ThreadPoolExecutor.CallerRunsPolicy());
        executor.initialize();
        return executor;
    }


}

2，在实现方法上加上
@Async(value = "taskExecutor")  即可。
