@Test
public void testInbound() {
    @SuppressWarnings("unchecked") final Message<String> out = (Message<String>) new ObjectToJsonTransformer().transform(new GenericMessage<Foo>(new Foo()));
    MessageProperties messageProperties = new MessageProperties();
    DefaultAmqpHeaderMapper.outboundMapper().fromHeadersToRequest(out.getHeaders(), messageProperties);
    final BasicProperties props = new DefaultMessagePropertiesConverter().fromMessageProperties(messageProperties, "UTF-8");
    this.rabbitTemplate.execute(channel -> {
        channel.basicPublish("", JSON_TESTQ, props, out.getPayload().getBytes());
        return null;
    });
    Object received = this.rabbitTemplate.receiveAndConvert(JSON_TESTQ);
