在Spring boot中自訂RabbitMQ的messageConverter_Spring</div>

@Configurationpublic class GlobalConfig {    //以下配置RabbitMQMessage Service    @Autowired    public ConnectionFactory connectionFactory;    @Bean    public SimpleRabbitListenerContainerFactory rabbitListenerContainerFactory() {        SimpleRabbitListenerContainerFactory factory = new SimpleRabbitListenerContainerFactory();        factory.setConnectionFactory(connectionFactory);        factory.setConcurrentConsumers(3);        factory.setMaxConcurrentConsumers(10);        return factory;    }    @Bean    public MessageConverter jsonMessageConverter() {        return new Jackson2JsonMessageConverter();    }    @Bean    public RabbitTemplate rabbitTemplate() {        RabbitTemplate template = new RabbitTemplate(connectionFactory);        template.setMessageConverter(jsonMessageConverter());        return template;    }}

這樣配置後，就可以通過rabbitTemplate.convertAndSend(createCustomerQueueName, requestWrapper);來自動序列化成json字串了。

RequestWrapper requestWrapper = new RequestWrapper();rabbitTemplate.convertAndSend("queue", requestWrapper);

消費的地方是

@RabbitListener(queues = "queue")public void processCreateCustomer(@Payload RequestWrapper requestWrapper, @Header(AmqpHeaders.DELIVERY_TAG) long deliveryTag, Channel channel) throws IOException {// 處理成功channel.basicAck(deliveryTag,false);// 處理失敗channel.basicNack(deliveryTag, false, true);}
