二、线程池配置bean  @EnableAsync、@Async

@Configuration
@EnableAsync
public class ThreadPoolConfig {
    private static final Logger logger = LoggerFactory.getLogger(ThreadPoolConfig.class);

    @Bean
    public Executor asyncServiceExecutor(){
        logger.info("start asyncServiceExecutor");
        ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
        executor.setCorePoolSize(6);
        executor.setMaxPoolSize(12);
        executor.setQueueCapacity(50);
        executor.setKeepAliveSeconds(3);
        executor.setThreadNamePrefix("AsyncService-");
        executor.initialize();
        return executor;
    }
}

@Async("asyncServiceExecutor")
pulic void xxx(){
    //todo
}
