springboot 开启@Async异步注解配置默认线程池

继承org.springframework.scheduling.annotation.AsyncConfigurer 重写其getAsyncExecutor方法，从而实现@Async默认线程池的配置

@Slf4j
@EnableAsync
@Configuration
@RequiredArgsConstructor
public class AsyncConfig implements AsyncConfigurer {

    private final ExecutorService threadPoolExecutor;

    @Override
    public Executor getAsyncExecutor() {
        return threadPoolExecutor;
    }

    @Override
    public AsyncUncaughtExceptionHandler getAsyncUncaughtExceptionHandler() {
        return (arg0, arg1, arg2) -> {
            log.error("Async uncaught exception,throwable:{},method:{},params:{}", arg0,arg1,arg2);
        };
    }

}
