在Spring Boot AMQP中为RabbitMQ配置ConnectionFactory

Question

TL; DR如何以编程方式创建Spring Boot AMQP连接工厂？

嘿，

为了连接到RabbitMQ，我将它们添加到application.properties了Spring Boot应用程序的文件中：

spring.rabbitmq.host=host
spring.rabbitmq.port=5672
spring.rabbitmq.username=myapp
spring.rabbitmq.password=mypass

根据我的理解，然后将这些值用于创建Spring Boot的自动配置ConnectionFactory，然后将其用于：

@Bean
@Conditional(RabbitCondition.class)
SimpleMessageListenerContainer container(ConnectionFactory connectionFactory, MessageListenerAdapter completedOrderListenerAdapter) {
    SimpleMessageListenerContainer container = new SimpleMessageListenerContainer();
    container.setConnectionFactory(connectionFactory);
    container.setQueueNames(completedOrderQueueName);
    container.setMessageListener(completedOrderListenerAdapter);
    return container;
}

我希望能够使用不是的不同环境文件中的RabbitMQ凭证application.properties，因此我想以ConnectionFactory编程方式创建bean。我该如何实现？

谢谢。

@Bean
public ConnectionFactory connectionFactory() {
    CachingConnectionFactory connectionFactory = new CachingConnectionFactory();
    connectionFactory.setAddresses(address);
    connectionFactory.setUsername(username);
    connectionFactory.setPassword(password);
    return connectionFactory;
}
