问题
I've the following two Configuration classes:
@Configuration
@EnableRabbit
@Import({ LocalRabbitConfigA.class, CloudRabbitConfigA.class })
public class RabbitConfigA {
@Autowired
@Qualifier("rabbitConnectionFactory_A")
private ConnectionFactory rabbitConnectionFactory;
@Bean(name = "admin_A")
AmqpAdmin amqpAdmin() {
return new RabbitAdmin(rabbitConnectionFactory);
}
@Bean(name = "Exchange_A")
DirectExchange receiverExchange() {
return new DirectExchange("Exchange_A", true, false);
}
}
And
@Configuration
@EnableRabbit
@Import({ LocalRabbitConfigB.class, CloudRabbitConfigB.class })
public class RabbitConfigB {
@Autowired
@Qualifier("rabbitConnectionFactory_B")
private ConnectionFactory rabbitConnectionFactory;
@Bean(name = "admin_B")
AmqpAdmin amqpAdmin() {
return new RabbitAdmin(rabbitConnectionFactory);
}
@Bean(name = "Exchange_B")
DirectExchange receiverExchange() {
return new DirectExchange("Exchange_B", true, false);
}
}
Note that the LocalRabbitConfigA and LocalRabbitConfigB classes define the connectionFactory which connects to a different VHost.
When starting the application (within Tomcat), all the Exchanges are created in both VHosts.
The question is how to define that a certain Exchange/Queue is created by a specific ConnectionFactiory ?
So that VHost A contains only the Exchange_A, and VHost B only Exchange_B ?
回答1:
See conditional declaration.
Specifically:
@Bean(name = "Exchange_B")
DirectExchange receiverExchange() {
DirectExchange exchange = new DirectExchange("Exchange_B", true, false);
exchange.setAdminsThatShouldDeclare(amqpAdmin());
return exchange;
}
