@Component
public class TaskPoolConfig {

    @Bean(name = "threadPoolTaskExecutor")
    public Executor taskExecutor() {
        ThreadPoolTaskExecutor taskExecutor = new ThreadPoolTaskExecutor();
        //核心线程池大小,设置为当前系统可用的处理器数量+1
        taskExecutor.setCorePoolSize(Runtime.getRuntime().availableProcessors() + 1);
        //最大线程池大小,设置为当前系统可用的处理器数量*2
        taskExecutor.setMaxPoolSize(Runtime.getRuntime().availableProcessors() * 2);
        //队列最大容量
        taskExecutor.setQueueCapacity(1000);
        //存活时间
        taskExecutor.setKeepAliveSeconds(60);
        //设置线程名前缀
        taskExecutor.setThreadNamePrefix("taskExecutor--");
        taskExecutor.setWaitForTasksToCompleteOnShutdown(true);
        //拒绝策略
        taskExecutor.setRejectedExecutionHandler(new ThreadPoolExecutor.CallerRunsPolicy());
        taskExecutor.setAwaitTerminationSeconds(60);
        return taskExecutor;
    }
｝

使用:

  1.首先注入线程池对象

    @Autowired
    @Qualifier("threadPoolTaskExecutor")
    private Executor threadPoolTaskExecutor;

2.方法里面使用线程池 

threadPoolTaskExecutor.execute(() -> {
   //代码逻辑
});
