below mentioned is configuration of the application.yml and pom.xml file

# RabbitMQ configuration

Any Help is Appreciated, Thanks

Answer 1

#spring.rabbitmq.host=amqps://b--9c-4b44-97c4-a3526fa7d4ee.mq.-east-1.amazonaws.com

Taking hint from the above commented host property, it seems you have SSL enabled.

You can explicitly tell Spring to use SSL with spring.rabbitmq.ssl.enabled property. This is how the entire set of properties would look like

spring.rabbitmq.ssl.enabled=true
spring.rabbitmq.host=b-XXXX-27f68f8379d3.mq.aws-region.amazonaws.com
spring.rabbitmq.port=5671
spring.rabbitmq.username=<YourUserName>
spring.rabbitmq.password=<YourPassword>

Or you can provide the addresses along with the username and password and Spring Boot would figure out that it needs to use amqps and port 5671

spring.rabbitmq.addresses=amqps://b-XXXX-27f68f8379d3.mq.aws-region.amazonaws.com:5671
spring.rabbitmq.username=<YourUserName>
spring.rabbitmq.password=<YourPassword>

Answer 2

I was able to solve the same issue by adding following config

    spring:
      rabbitmq:
        host: YOUR_HOST_NAME
        port: 5671
        username: YOUR_USER_NAME
        password: YOUR_PASSWORD
          ssl:
            enabled: true
            algorithm: TLSv1.2

Last part algorithm:TSLv1.2 is important. Without it I was getting

org.springframework.amqp.AmqpIOException: javax.net.ssl.SSLHandshakeException: Received fatal alert: protocol_version at 

Answer 3

i have to set ssl property to true to get connected to AWS Rabbitmq, but setting the property "spring.rabbitmq.ssl.enabled=true" through application.yml didnt work in my case, i had to create a bean in a configuration class to set it, the below is the code which worked for me

@Bean 
public CachingConnectionFactory rabbitConnectionFactory() throws Exception 
{
  ConnectionFactory factory = new ConnectionFactory(); 
  factory.setHost(host);
  factory.setUsername(username); 
  factory.setPassword(password);
  factory.setPort(5671);
  **factory.useSslProtocol();**  
  CachingConnectionFactory connectionFactory = new CachingConnectionFactory(factory); 
  return connectionFactory; 
}

Answer 4

Bellow, mine configuration, that works well with SpringBoot 2.4.5

  @Value("${spring.rabbitmq.addresses}")
    private String addresses;
    @Value("${spring.rabbitmq.username}")
    private String rabbitmqUsername;
    @Value("${spring.rabbitmq.password}")
    private String rabbitmqPassword;
    @Value("${spring.rabbitmq.virtual-host}")
    private String rabbitmqVirtualHost;
    @Bean
    public ConnectionFactory connectionFactory() {
    CachingConnectionFactory connectionFactory =new CachingConnectionFactory();
    connectionFactory.setUri(addresses);
    connectionFactory.setUsername(rabbitmqUsername);
    connectionFactory.setPassword(rabbitmqPassword);
    connectionFactory.setVirtualHost(rabbitmqVirtualHost);
    return connectionFactory;
    }
