线程基本介绍和创建方式
jdk自带的线程池
java.util.concurrent包提供了线程相关的类，ThreadPoolExecutor用于创建一个线程池，通常我们会这样创建一个线程池
private ThreadPoolExecutor scheduleExecutor =
new ThreadPoolExecutor(100, 100, 0, TimeUnit.MILLISECONDS, new ArrayBlockingQueue<>(100),
new NamedThreadFactory("basic-data"), new LoggerDiscardPolicy());
spring的线程池
spring的线程池是对ThreadPoolExecutor的封装
@Configuration
public class ThreadPoolConfig {
@Bean("threadPoolTaskExecutor")
public ThreadPoolTaskExecutor threadPoolTaskExecutor(){
ThreadPoolTaskExecutor threadPoolTaskExecutor=new ThreadPoolTaskExecutor();
threadPoolTaskExecutor.setCorePoolSize(4);
threadPoolTaskExecutor.setKeepAliveSeconds(10);
threadPoolTaskExecutor.setMaxPoolSize(10);
threadPoolTaskExecutor.setQueueCapacity(10);
return threadPoolTaskExecutor;
}
}
