Choosing the ExecutorService

Methods are called asynchronously using an ExecutorService. If not further specified (see below) a default executor will be used for running the annotated method. The framework does allow to customize which executor will be used. For each annotated method you can define a Key that is used to look up the actual Executor implementation from the Injector. You can use the @Executor annotation for specifying the Executor type. Optionally you can put a binding annotation to further refine the Key.

    @Async
    @Executor(MyVerySpecialCustomExecutor.class)
    @Named("firstVerySpecialCustomExecutor")
    public void sendMail(MailOptions options) {
        // Executor will be retrieved using Key.get(MyVerySpecialCustomExecutor.class, 
        //     Names.named("firstVerySpecialCustomExecutor"))
    }
    
    @Async
    @Named("sendMailThread")
    public void sendMailAlternatively(MailOptions options) {
        // Executor will be retrieved using Key.get(ExecutorService.class, 
        //     Names.named("sendMailThread"))
    }
}
