By default when specifying @Async
on a method, the executor that will be used is the one supplied to the 'annotation-driven' element as described here.
However, the value attribute of the @Async
annotation can be used when needing to indicate that an executor other than the default should be used when executing a given method.
@Async("otherExecutor")
void doSomething(String s) {
// this will be executed asynchronously by "otherExecutor"
}
In this case, "otherExecutor" may be the name of any Executor bean in the Spring container, or may be the name of a qualifier associated with any Executor, e.g. as specified with the element or Spring’s @Qualifier
annotation
https://docs.spring.io/spring/docs/current/spring-framework-reference/html/scheduling.html
And probably you need to specify the otherExecutor bean in you app with the pool settings you wish.
@Bean
public TaskExecutor otherExecutor() {
ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
executor.setCorePoolSize(5);
executor.setMaxPoolSize(10);
executor.setQueueCapacity(25);
return executor;
}
