[FIXED] Create SSLContext for RabbitMQ configuration with Spring

Issue

I need to create and set a SSLContext to connect to a RabbitMQ queue with Spring framework. I use the @RabbitListener annotation and without SSLContext, by setting hostname, port, username and password into the application.properties file, all the things works just perfect.

But how can I manually set a SSLContext? The application.properties want a JKS and I can't use it. I see some configurations beans but what I found online is not clear at all.

How can I configure manually/programmatically (SSLContext precisly) RabbitMQ on Spring framework?

Solution

Create a class that extends RabbitConnectionFactoryBean and override createSSLContext().

/**
 * Override this method to create and/or configure the {@link SSLContext} used
 * by the {@link ConnectionFactory}.
 * @return The {@link SSLContext}.
 * @throws NoSuchAlgorithmException if the algorithm is not available.
 * @since 1.4.4
 */
protected SSLContext createSSLContext() throws NoSuchAlgorithmException {
    return SSLContext.getInstance(this.sslAlgorithm);
}

Then declare a CachingConnectionFactory bean that uses the rabbit connection factory created by the factory bean.
