Suggestion

• org.springframework.scheduling.annotation.Async enhancement

@Target({ElementType.TYPE, ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
@Documented
public @interface Async {

    String value() default "";

    /**
     * limit and control the concurrent thread num to avoid OOM  , outer-interface QPS limited and so on
     * 
     * if null , use global threadpool
     * if not null，create a threadpool , when method or class is invoked ，use the current threadpool
     */
        Integer threadNum() default null;
}

i will not need to definite threadpools for each scene ，just only definite @Async on the method

consider it ?

Thanks for the suggestion but configuring the threadpool is already supported, please see AsyncConfigurer and the reference documentation.

@snicoll but AsyncConfigurer is global ，i want each method have a pool

Comment From: snicoll

each @Async method can refer to a TaskExecutor bean, see https://docs.spring.io/spring-framework/docs/current/reference/html/integration.html#scheduling-annotation-support-qualification
