为bean定义工厂方法指定不同的名称。通常，按照约定，您将它们命名为与队列相同的名称，但这不是必需的…
@Bean
Queue queue1() {
return new Queue(queueNameAAA, false);
}
@Bean
Queue queue2() {
return new Queue(queueNameBBB, false);
}
在绑定bean中使用队列时，有两种选择：
@Bean
Binding binding1(@Qualifier("queue1") Queue queue, TopicExchange exchange) {
return BindingBuilder.bind(queue).to(exchange).with(queueNameAAA);
}
@Bean
Binding binding2(@Qualifier("queue2") Queue queue, TopicExchange exchange) {
return BindingBuilder.bind(queue).to(exchange).with(queueNameBBB);
}
要么
@Bean
Binding binding1(TopicExchange exchange) {
return BindingBuilder.bind(queue1()).to(exchange).with(queueNameAAA);
}
@Bean
Binding binding2(TopicExchange exchange) {
return BindingBuilder.bind(queue2()).to(exchange).with(queueNameBBB);
}
甚至更好…
@Bean
Binding binding1(TopicExchange exchange) {
return BindingBuilder.bind(queue1()).to(exchange).with(queue1().getName());
}
@Bean
Binding binding2(TopicExchange exchange) {
return BindingBuilder.bind(queue2()).to(exchange).with(queue2().getName());
}
