这篇文章主要介绍了JDK线程池和Spring线程池的使用实例解析,文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下

JDK线程池和Spring线程池实例，异步调用，可以直接使用

(1)JDK线程池的使用，此处采用单例的方式提供，见示例：

public class ThreadPoolUtil {
	private static int corePoolSize = 5;
	private static int maximumPoolSize = 10;
	private static long keepAliveTime = 60L;
	private static TimeUnit unit = TimeUnit.SECONDS;
	private static int capacity = 1024;
	private static ThreadFactory namedThreadFactory = new ThreadFactoryBuilder().setNameFormat("jdk-thread-pool-%d").build();
	private static final ExecutorService executorService = new ThreadPoolExecutor(corePoolSize,
	maximumPoolSize,
	keepAliveTime,
	unit,
	new LinkedBlockingQueue<>(capacity),
	namedThreadFactory,
	new ThreadPoolExecutor.AbortPolicy());
	private ThreadPoolUtil () {
	}
	public static ExecutorService getExecutorService () {
		return executorService;
	}
}

在其它地方可以直接这样使用：

ThreadPoolUtil.getExecutorService().execute(() -> {
	System.out.println("test1");
	System.out.println("test2");
}
)

(2)Spring线程池的使用，此处通过配置类的方式配置线程池的相关属性，见示例：

@Configuration
@EnableAsync
public class DocataThreadBeanConfig {
	private int corePoolSize = 5;
	private int maxPoolSize = 10;
	private int queueCapacity = 1024;
	private String namePrefix = "async-service-task-";
	// 上述属性可以通过@Value来读取配置值
	@Bean(name = "asyncServiceTaskExecutor")
	public TaskExecutor asyncServiceExecutor() {
		ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
		// 设置核心线程数
		executor.setCorePoolSize(corePoolSize);
		// 设置最大线程数
		executor.setMaxPoolSize(maxPoolSize);
		// 设置队列容量
		executor.setQueueCapacity(queueCapacity);
		// 设置线程活跃时间（秒）
		executor.setKeepAliveSeconds(60);
		// 设置默认线程名称
		executor.setThreadNamePrefix(namePrefix);
		// 设置拒绝策略
		executor.setRejectedExecutionHandler(new ThreadPoolExecutor.CallerRunsPolicy());
		// 等待所有任务结束后再关闭线程池
		executor.setWaitForTasksToCompleteOnShutdown(true);
		executor.initialize();
		;
		return executor;
	}
}

在其它文件中需要这样使用：

@Resource(name="asyncServiceTaskExecutor")
private ThreadPoolTaskExecutor asyncServiceTaskExecutor;

不要直接使用@Autowired，否则会提示失败的

@Autowired
private ThreadPoolTaskExecutor asyncServiceTaskExecutor;
