How can I configure RabbitMQ authentication mechanism in Spring Boot? - spring-boot

Question

#Configuration
#EnableRabbit
public class RabbitConfiguration {
private static final String queueName = "3055";
private static final String topicExchangeName = queueName + "-exchange";
#Bean
Queue queue() {
return new Queue(queueName, false);
}
#Bean
TopicExchange exchange() {
return new TopicExchange(topicExchangeName);
}
#Bean
Binding binding(Queue queue, TopicExchange exchange) {
return BindingBuilder.bind(queue).to(exchange).with("foo.bar.#");
}
#Bean
RabbitTemplate rabbitTemplate(ConnectionFactory connectionFactory,
MessageConverter messageConverter) {
RabbitTemplate rabbitTemplate = new RabbitTemplate(connectionFactory);
rabbitTemplate.setMessageConverter(messageConverter);
return rabbitTemplate;
}
#Bean
MessageConverter messageConverter() {
return new Jackson2JsonMessageConverter();
}
}
Code above is my Spring Boot Project's RabbitMQ configuration class.
However, I cannot connect the RMQ server since below error pops up every time I try to connect.
Caused by: com.rabbitmq.client.AuthenticationFailureException: ACCESS_REFUSED - Login was refused using authentication mechanism PLAIN. For details see the broker logfile.
The Server provider told me that I need to set the authentication mechanism to AMQPLAIN.
My question is that How can I set authentication mechanism to AMQPLAIN?
No matter how much I google, I couldn't figure out how.

I confirm to #Raja Anbazhagan. Check the RabbitMQ logs first. Supposedly your user credentials were guest/guest.
The easiest way to solve your problem could be to add those lines in your application.yml:
spring:
rabbitmq:
username: <user-name>
password: <user-password>
