spring之@EnableAsync @Async 的详解以及ThreadPoolConfig配置

@Configuration
@EnableAsync
@Slf4j
public class ThreadPoolConfig {
          
   

    private static final int AVAILABLE_PROCESSORS = Runtime.getRuntime().availableProcessors();
    private static final String SERVICE_THREAD = "serviceThread-";
    private static final String MVC_THREAD = "MvcThread-";
    private static final int QUEUE_CAPACITY = 1500;

    public ThreadPoolConfig() {
          
   
        log.info("[ThreadPoolConfig] init ..");
    }

    /**

        executor.setCorePoolSize(AVAILABLE_PROCESSORS + 1);
        executor.setThreadNamePrefix(SERVICE_THREAD);
        executor.setQueueCapacity(QUEUE_CAPACITY);
