You can use the RabbitAdmin instance to get the details from the queue, as follows:

@Resource RabbitAdmin admin;
...
protected int getQueueCount(final String name) {
    DeclareOk declareOk = admin.getRabbitTemplate().execute(new ChannelCallback() {
        public DeclareOk doInRabbit(Channel channel) throws Exception {
            return channel.queueDeclarePassive(name);
        }
    });
    return declareOk.getMessageCount();
}
