spring boot 如何使用多线程

package com.jmxf.core.config;

import java.util.concurrent.Executor;

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

@Configuration
@EnableAsync  // 启用异步任务
public class AsyncConfiguration {

    // 组件计算
    @Bean("zjExecutor")
    public Executor asyncExecutor() {
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        //核心线程数5：线程池创建时候初始化的线程数
        executor.setCorePoolSize(5);
        //最大线程数5：线程池最大的线程数，只有在缓冲队列满了之后才会申请超过核心线程数的线程
        executor.setMaxPoolSize(10);
        //缓冲队列500：用来缓冲执行任务的队列
        executor.setQueueCapacity(500);
        //允许线程的空闲时间60秒：当超过了核心线程出之外的线程在空闲时间到达之后会被销毁
        executor.setKeepAliveSeconds(60);
        //线程池名的前缀：设置好了之后可以方便我们定位处理任务所在的线程池
        executor.setThreadNamePrefix("DailyAsync-");
        executor.initialize();
        return executor;
    }
}

package com.jmxf.service.fkqManage.zj;


import org.springframework.scheduling.annotation.Async;

@Service

     */
