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@EnableAsyncpublic 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

@Autowiredprivate ThreadPoolTaskExecutor asyncServiceTaskExecutor;

以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持。
