SpringBoot项目集成RabbitMq

SpringBoot项目 集成RabbitMq

---

RabbitMq是目前比较流行的几个Mq之一,也是Spring官方AMQP的实现,官方文档地址:

https://docs.spring.io/spring-amqp/docs/2.0.0.RELEASE/reference/html/

RabbitMq也是国内很多互联网公司都在使用,今天主要说一下,它咋SpringBoot项目中的具体实现.

1.首先在pom中添加依赖

SpringBoot已经帮我们封装好了依赖,只需要我们导入到自己的pom文件中就可以.
<!-- RabbitMq队列 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-amqp</artifactId>
</dependency>

2.添加RabbitMq服务器的配置信息

这个你可以写在一个properties文件中,使用的时候可以用@value(${xxx})把每个参数挨个读取到类中使用,也可以直接用一个bean直接接受这几个参数,这样更优雅一些,我这里使用的是后者.

properties文件中的配置信息:
spring.rabbitmq.host=172.xx.xx.xxx
spring.rabbitmq.port=5672
spring.rabbitmq.username=xxxx
spring.rabbitmq.password=xxxx

接受参数的bean
@Component
@ConfigurationProperties(prefix = "spring.rabbitmq")
public class RabbitMqConfig {
private String host;
private Integer port;
private String username;
private String password;
//省略get() set()

3.写一个configuration类添加配置信息

`/**

* 队列连接工厂类
*
* @author hou
* @date 2017-11-13 10:35
*/
@Configuration
public class RabbitMqConfiguration {
private static final Logger logger = LogManager.getLogger(RabbitMqConfiguration.class);

@Autowiredprivate RabbitMqConfig rabbitMqConfig;/** * 配置队列连接Factory * @return */@Beanpublic ConnectionFactory connectionFactory() {    CachingConnectionFactory connectionFactory = new CachingConnectionFactory(rabbitMqConfig.getHost(),rabbitMqConfig.getPort());    connectionFactory.setUsername(rabbitMqConfig.getUsername());    connectionFactory.setPassword(rabbitMqConfig.getPassword());

// connectionFactory.setVirtualHost(this.mqRabbitVirtualHost);
connectionFactory.setPublisherConfirms(true);
return connectionFactory;
}

/** * 用来发送消息 * @return */@Beanpublic RabbitTemplate rabbitTemplate() {    RabbitTemplate template = new RabbitTemplate(connectionFactory());    return template;}/** * 配置交换机 * @return */@Beanpublic DirectExchange defaultExchange() {    return new DirectExchange(Constants.EXCHANGE_NAME_MESSAGE);}/** * 构建队列，名称，是否持久化之类 * @return */@Beanpublic Queue toonMessageQueue() {    return new Queue(Constants.QUEUE_NAME_TOON_MESSAGE, true);}/** * 将DirectExchange与Queue进行绑定 * @return */@Beanpublic Binding binding() {    return BindingBuilder.bind(toonMessageQueue()).to(defaultExchange()).with(Constants.ROUTING_KEY_MESSAGE);}@Autowiredprivate MessageListener messageListener;@Beanpublic SimpleMessageListenerContainer execMessageContainerOne() {    //设置监听者“容器”    SimpleMessageListenerContainer container = new SimpleMessageListenerContainer(connectionFactory());    //设置队列名    container.setQueueNames(Constants.QUEUE_NAME_TOON_MESSAGE);    //设置监听者数量，即消费线程数    container.setConcurrentConsumers(1);    container.setMessageListener((ChannelAwareMessageListener) (message, channel) -> {        byte[] body = message.getBody();        if(null != body) {            try {                String msg = new String(body);                //消费消息                messageListener.listenerAndSendToonMessage(msg);            } catch(Exception e) {                e.printStackTrace();            }        }    });    return container;}`

4.处理消息的实现方法,和放入消息的方法

放入消息的实现:
`
/**
* 队列消费者实现类
*
* @author 146584
* @date 2017-11-13 11:19
*/
@Service
public class QueueProductServiceImpl implements RabbitTemplate.ConfirmCallback{
private static final Logger logger = LogManager.getLogger(QueueProductServiceImpl.class);

@Autowiredprivate RabbitTemplate rabbitTemplate;public QueueProductServiceImpl(RabbitTemplate rabbitTemplate){    this.rabbitTemplate=rabbitTemplate;    this.rabbitTemplate.setConfirmCallback(this);}@Overridepublic void confirm(CorrelationData correlationData, boolean ack, String cause) {    logger.info(":===>消息id:" + correlationData);    if (ack) {        logger.info("放入队列成功");    } else {        logger.info("放入队列失败:" + cause);    }}/** * 发送消息，不需要实现任何接口，供外部调用 * @param msg */public void send(String msg){    CorrelationData correlationId = new CorrelationData(UUID.randomUUID().toString());    String result = rabbitTemplate.convertSendAndReceive(Constants.EXCHANGE_NAME_MESSAGE,Constants.ROUTING_KEY_MESSAGE, msg, correlationId)+"";}`

消息消费的实现

`@Service

public class MessageListener {
private static final Logger logger = LogManager.getLogger(MessageListener.class);

public void listenerAndSendToonMessage(String message) {    //此处省略处理逻辑}`

写一个测试用例测试一下
` @Autowired
private MessageQueueController messageQueueController;

@Testpublic void testSendMsg(){    List<MessageEntity> messageEntityList = new ArrayList<>();    for(int i=0;i<200;i++){        MessageEntity entity = new MessageEntity();        //设置参数....        messageEntityList.add(entity);    }    messageQueueController.sendMessageByQueue(messageEntityList);}`
