ThreadFactory 线程池工厂

import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;

public class ThreadFactory {
    private static ExecutorService threadpool = Executors.newFixedThreadPool(200);

    public static ExecutorService getThreadpool() {
        return threadpool;
    }
}

固定线程池默认抛弃策略，线程超过数量被抛弃不执行，但是队列默认数量是整形的最大数，一般是超不过队列数量加线程池数量

spring线程池

import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;

import com.yundaex.common.dao.context.SpringContext;

public class ThreadFactory {
    private static ThreadPoolTaskExecutor threadpool = (ThreadPoolTaskExecutor) SpringContext.getBean("taskExecutor");

    public static ThreadPoolTaskExecutor getThreadpool() {
        return threadpool;
    }
}
