Spring boot下使用RabbitMQ实例

环境搭建教程请参考：http://blog.csdn.net/yy756127197/article/details/73693527

rabbitmq配置文件

@Configuration//@ConditionalOnProperty(prefix = "rabbitmq",name = "queuename")public class MQConfig {    @Configuration    @Profile("dev")  //dev环境的配置    static class LocalConfiguration {        @Value("${rabbitmq.queuename}")        private String queueName;        @Value("${rabbitmq.exchange}")        private String queueExchange;        @Value("${rabbitmq.routingkey}")        private String routingkey;        @Value("${cf.rabbit.service.name}")        private String rabbitService;        @Bean        public ConnectionFactory connectionFactory() {            CachingConnectionFactory factory = new CachingConnectionFactory();            factory.setUsername("yang");            factory.setPassword("guest");            factory.setVirtualHost("test");            factory.setHost("localhost");            // factory.setPort(15672);            factory.setPublisherConfirms(true);            return factory;        }        @Bean        public MessageConverter messageConverter() {            return new Jackson2JsonMessageConverter();        }        @Bean        @Scope(ConfigurableBeanFactory.SCOPE_PROTOTYPE)        // 必须是prototype类型        public RabbitTemplate rabbitTemplate() {            RabbitTemplate template = new RabbitTemplate(connectionFactory());            return template;        }        @Bean        public MessageListenerAdapter listenerAdapter(MQAwareListener listener,                MessageConverter converter) {            return new MessageListenerAdapter(listener, converter);        }        @Bean        public Queue queue() {            return new Queue(queueName, true);        }        // TopicExchange(*、#模糊匹配routing key，routing        // key必须包含".")，DirectExchange，FanoutExchange(无routing key概念)        @Bean        public TopicExchange exchange() {            return new TopicExchange(queueExchange);        }        @Bean        public Binding binding(Queue queue, TopicExchange exchange) {            return BindingBuilder.bind(queue).to(exchange).with(routingkey);        }    }}

listener 客户端

@Componentpublic class MQAwareListener implements ChannelAwareMessageListener {    @Resource    private MessageConverter messageConverter;    @Resource    private RabbitTemplate rabbitTemplate;    @Override    public void onMessage(Message message, Channel channel) throws IOException {          byte[] body = message.getBody();            TUserTest user= DataConverterUtil.json2Object(new String(body), TUserTest.class);          System.out.println("接收消息 : " + user.getName());  //      消息消费失败//      channel.basicNack(message.getMessageProperties().getDeliveryTag(), false, false);        //确认消息成功消费        channel.basicAck(message.getMessageProperties().getDeliveryTag(), false);    }}

DataConverterUtil.json2Object()是我自己封装的类型转换工具类。json转对象，网上搜一大把
发送端

@Servicepublic class BasicService implements ConfirmCallback {    @Resource    public RabbitTemplate rabbitTemplate;    @Value("${rabbitmq.exchange}")    private String queueExchange;    @Value("${rabbitmq.routingkey}")    private String routingkey;    public void sendMessage(final String correlationId, Object request) {        String content = DataConverterUtil.object2Json(request);        rabbitTemplate.setConfirmCallback(this);        rabbitTemplate.setCorrelationKey(correlationId);        rabbitTemplate.convertAndSend(queueExchange,routingkey, content, new MessagePostProcessor() {              //设置消息的通用属性            @Override            public Message postProcessMessage(Message message) throws AmqpException {                message.getMessageProperties().setTimestamp(new Date());//                message.getMessageProperties().setDeliveryMode(MessageDeliveryMode.PERSISTENT);                 return message;            }        }, new CorrelationData(correlationId));    }    @Override    public void confirm(CorrelationData correlationData, boolean ack, String cause) {        System.out.println("回调id:" + correlationData);        if (ack) {            System.out.println("消息发送成功");        } else {            System.out.println("消息发送失败:" + cause);        }    }}

DataConverterUtil.object2Json()是我自己封装的类型转换工具类。对象转json，网上搜一大把
测试类

@Component@EnableSchedulingpublic class TestSend {    @Resource    private BasicService basicService;    @Scheduled(fixedDelay = 60000)    public void send() {        TUserTest user = new TUserTest();        user.setId(UUID.randomUUID().toString());        user.setName("我是拯救世界的Programmer");        basicService.sendMessage(user.getId(), user);    }}

以上是带回调的事例（手动回调）
远离监听，长命百岁
总觉得这种实现方式不是很好，下一章讲客户端注解的形式。
但是注解的形式手动回调怎么设置，没搞明白，只能自动回调。玩明白的小伙伴分享下哦。
