springboot线程池创建与使用

/*** @author: zcs* @Title: TaskPoolConfig* @Description: 线程池配置* @date: 2023/10/11 17:52*/
@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+1taskExecutor.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*2taskExecutor.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
});
