How to create a rabbitmq Queue in Spring Boot but without using @Bean-CodePudding

In My Scenario I need to create a lots of queues dynamically at run time that is why I don't want to use @Bean instead want to write a function that create queue and I will call it whenever necessary. Here When i use @bean annotation it creates queue on rabbitmq server.

@Bean
public Queue productQueue(final String queueName) {
    return new Queue(queueName);
}

But with the same code without @Bean

public Queue productQueue(final String queueName) {
    return new Queue(queueName);
}

when call this function doesn't create queue on rabbitmq server

Queue queue = <Object>.productQueue("product-queue");

CodePudding user response：

The Queue object must be a bean in the context and managed by Spring. To create queues dynamically at runtime, define the bean with scope prototype:

@Bean
@Scope("prototype")
public Queue productQueue(final String queueName) {
    return new Queue(queueName);
}

and create queues at runtime using ObjectProvider:

@Autowired
private ObjectProvider<Queue> queueProvider;

Queue queue1 = queueProvider.getObject("queueName1");
Queue queue2 = queueProvider.getObject("queueName2");
