public @interface Async { /** * A qualifier value for the specified asynchronous operation(s). * <p>May be used to determine the target executor to be used when executing this * method, matching the qualifier value (or the bean name) of a specific * {@link java.util.concurrent.Executor Executor} or * {@link org.springframework.core.task.TaskExecutor TaskExecutor} * bean definition. * <p>When specified on a class level {@code @Async} annotation, indicates that the * given executor should be used for all methods within the class. Method level use * of {@code Async#value} always overrides any value set at the class level. * @since 3.1.2 */ String value() default ""; }
