    public Queue myQueue(){
        return new Queue("q.example", true);
    }
    
    @Bean
    public DirectExchange exchange(){
        return new DirectExchange("e.direct-exchange");
    }
    
    @Bean
    public Binding binding(){
        return BindingBuilder.bind(this.myQueue()).to(this.exchange()).with("q-routing-key");
