Question

I am not able to conncet to RabbitMQ.RabbitMQ is not on local machine .
import org.springframework.amqp.core.Binding;
import org.springframework.amqp.core.BindingBuilder;
import org.springframework.amqp.core.Queue;
import org.springframework.amqp.core.TopicExchange;
import org.springframework.amqp.rabbit.annotation.EnableRabbit;
import org.springframework.amqp.rabbit.connection.ConnectionFactory;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.amqp.rabbit.listener.SimpleMessageListenerContainer;
import org.springframework.amqp.rabbit.listener.adapter.MessageListenerAdapter;
import org.springframework.amqp.support.converter.Jackson2JsonMessageConverter;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.messaging.converter.MappingJackson2MessageConverter;
#Configuration
#EnableRabbit
public class AMQPConfig {
#Autowired
private RabbitMQProperties rabbitMQProperties;
#Bean
Queue queue() {
return new Queue(rabbitMQProperties.getQueueName(), false);
}
#Bean
TopicExchange exchange() {
return new TopicExchange(rabbitMQProperties.getExchangeName());
}
#Bean
Binding binding(Queue queue, TopicExchange exchange) {
return BindingBuilder.bind(queue).to(exchange).with(rabbitMQProperties.getRoutingKey());
}
#Bean
SimpleMessageListenerContainer container(ConnectionFactory connectionFactory,
MessageListenerAdapter listenerAdapter) {
SimpleMessageListenerContainer container = new SimpleMessageListenerContainer();
container.setConnectionFactory(connectionFactory);
System.out.println( " ques name is ------- " + rabbitMQProperties.getQueueName() );
container.setQueueNames(rabbitMQProperties.getQueueName());
container.setMessageListener(listenerAdapter);
return container;
}
#Bean
public MappingJackson2MessageConverter consumerJackson2MessageConverter() {
return new MappingJackson2MessageConverter();
}
#Bean
public RabbitTemplate amqpTemplate(ConnectionFactory connectionFactory) {
final RabbitTemplate rabbitTemplate = new RabbitTemplate(connectionFactory);
rabbitTemplate.setMessageConverter(messageConverter());
return rabbitTemplate;
}
#Bean
public Jackson2JsonMessageConverter messageConverter() {
return new Jackson2JsonMessageConverter();
}
#Bean
MessageListenerAdapter listenerAdapter(RabbitMqListener listener) {
return new MessageListenerAdapter(listener, "listen");
}
}
My application.properties looks like
spring.rabbitmq.password=pass
spring.rabbitmq.port=15671
spring.rabbitmq.username=user
spring.rabbitmq.host=https://urltologinscreen
I am able to access to Rabbitmq gui using
https://urltologinscreen:15671
I am getting the below error
ConfigServletWebServerApplicationContext
: Exception encountered during context initialization - cancelling refresh attempt:
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name

Parameter 0 of method amqpTemplate in pathhidden.rabbitmq.AMQPConfig required a bean of type
'org.springframework.amqp.rabbit.connection.ConnectionFactory' that

How do i resolve the issue?

Answer 1

Here is a simple solution that worked for me
Make sure RabbitMQ is defined on your properties file
spring.rabbitmq.host=localhost
spring.rabbitmq.port=5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest
On your pom.xml file, ensure to add the tag below under dependencies
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-amqp</artifactId>
</dependency>

Answer 2

My guess is that you properties should be like so:
spring.rabbitmq.password=pass
spring.rabbitmq.username=user
spring.rabbitmq.host=urltologinscreen
Don't need to specify the port or use http in the host
