By using annotations, the code becomes more readable and maintainable, as the event handling logicis clearly defined within the code. EventBus的关键原则之一是使用注解声明和处理事件。通过使用注解,订阅事件和处理事件变得更加简单,同时提高了代码的可读性和可维护性。 Another important aspect of EventBus ...
(Note that this isnot necessarilyindicative of a problem. There are many cases where an application will deliberately ignore a posted event, particularly if the event is coming from code you don't control.) To handle such events, register a subscriber method for theDeadEventclass. WheneverEvent...

In short,EventBusis not a singleton because we'd rather not make that decision for you. Use it how you like. Can I unregister a listener from the Event Bus? Yes, usingEventBus.unregister, but we find this is needed only rarely: ...
In the case of EventBusPolicy is possible to pass principal in a different way using L1 construct that does not cause the issue: new events.CfnEventBusPolicy(this, "MyPolicy", { statementId: "MyStatement", action: "events:PutEvents", principal: "123456789010", }); CDK CLI Version 2.63....
