1、增加rabbitmq的依赖包

<!-- amqp 依赖包 -->
<dependency>
<groupId>com.rabbitmq</groupId>
<artifactId>amqp-client</artifactId>
<version>5.2.0</version>
</dependency>
<dependency>
<groupId>org.springframework.amqp</groupId>
<artifactId>spring-rabbit</artifactId>
<version>2.0.2.RELEASE</version>
</dependency>

2、rabbitmq.properties文件中配置

rabbit.hosts=
rabbit.username=liam
rabbit.password=liam
rabbit.port=5672
rabbit.virtualHost=/
# 统一XML配置中易变部分的命名
rabbit.vhost=liam_host
rabbit.channelCacheSize=8
rabbit.queue=rabbitmq_test2
rabbit.exchange=rabbit_driect_mq_exchange
rabbit.routingKey=rabbitmq_test2
rabbit.publisher-confirms=true

3、RabbitMq的工厂连接和模板创建

@Configuration
public class RabbitConfig
{
@Value("${rabbit.hosts}")
private String host;
@Value("${rabbit.port}")
private String port;
@Value("${rabbit.username}")
private String username;
@Value("${rabbit.password}")
private String password;
@Value("${rabbit.publisher-confirms}")
private Boolean publisherConfirms;
@Value("${rabbit.vhost}")
private String virtualHost;
//创建工厂连接
@Bean
public ConnectionFactory connectionFactory(){
CachingConnectionFactory connectionFactory = new CachingConnectionFactory();
connectionFactory.setAddresses(this.host);
connectionFactory.setUsername(this.username);
connectionFactory.setPassword(this.password);
connectionFactory.setVirtualHost(this.virtualHost);
connectionFactory.setPublisherConfirms(this.publisherConfirms); //必须要设置
return connectionFactory;
}
//rabbitmq的模板配置
@Bean
@Scope(ConfigurableBeanFactory.SCOPE_PROTOTYPE) //必须是prototype类型
public RabbitTemplate rabbitTemplate() {
RabbitTemplate template = new RabbitTemplate(this.connectionFactory());
//template.setConfirmCallback(); 设置消息确认
//template.setReturnCallback();
return template;
}
}

4、创建交换机、创建队列、绑定交换机和队列

@Configuration
public class RabbitExchangeConfig
{
//直连交换机
@Bean
public DirectExchange defaultExchange() {
return new DirectExchange(RabbitConstant.EXCHANGE_NAME);
}
//队列
@Bean
public Queue queue() {
return QueueBuilder.durable(RabbitConstant.QUEUE_NAME).build();
}
//绑定
@Bean
public Binding binding() {
return BindingBuilder.bind(this.queue()).to(this.defaultExchange()).with(RabbitConstant.ROUTING_KEY);
}
/*@Bean
public Binding binding() {
return declare(new Binding(helloWorldQueue(), defaultDirectExchange()));
}*/
/*
@Bean
public TopicExchange helloExchange() {
return declare(new TopicExchange("hello.world.exchange"));
}*/
/*
public Queue declareUniqueQueue(String namePrefix) {
Queue queue = new Queue(namePrefix + "-" + UUID.randomUUID());
rabbitAdminTemplate().declareQueue(queue);
return queue;
}
// if the default exchange isn't configured to your liking....
@Bean Binding declareP2PBinding(Queue queue, DirectExchange exchange) {
return declare(new Binding(queue, exchange, queue.getName()));
}
@Bean Binding declarePubSubBinding(String queuePrefix, FanoutExchange exchange) {
return declare(new Binding(declareUniqueQueue(queuePrefix), exchange));
}
@Bean Binding declarePubSubBinding(UniqueQueue uniqueQueue, TopicExchange exchange) {
return declare(new Binding(uniqueQueue, exchange));
}
@Bean Binding declarePubSubBinding(String queuePrefix, TopicExchange exchange, String routingKey) {
return declare(new Binding(declareUniqueQueue(queuePrefix), exchange, routingKey));
}*/
}

5、生产者

@Component
public class RabbitSender implements RabbitTemplate.ConfirmCallback
{
@Autowired
private RabbitTemplate rabbitTemplate;
public void sendMsg(String content) {
CorrelationData correlationId = new CorrelationData(UUID.randomUUID().toString());
this.rabbitTemplate.setConfirmCallback(this); //rabbitTemplate如果为单例的话，那回调就是最后设置的内容
this.rabbitTemplate.convertAndSend(RabbitConstant.EXCHANGE_NAME,
RabbitConstant.ROUTING_KEY, content, correlationId);
}
//回调
@Override
public void confirm(CorrelationData correlationData, boolean ack, String cause) {
System.out.println(" 回调id:" + correlationData);
if (ack) {
System.out.println("消息成功消费");
} else {
System.out.println("消息消费失败:" + cause);
}
}
}

6、消费者

@Configuration
public class RabbitReceive
{
@Autowired
private RabbitConfig rabbitConfig;
@Autowired
private RabbitExchangeConfig rabbitExchangeConfig;
@Bean
public SimpleMessageListenerContainer messageContainer() {
SimpleMessageListenerContainer container = new SimpleMessageListenerContainer(rabbitConfig.connectionFactory());
container.setQueues(rabbitExchangeConfig.queue()); //设置要监听的队列
container.setExposeListenerChannel(true);
container.setMaxConcurrentConsumers(1);
container.setConcurrentConsumers(1);
container.setAcknowledgeMode(AcknowledgeMode.MANUAL); //设置确认模式手工确认
container.setMessageListener(new ChannelAwareMessageListener() {
@Override
public void onMessage(Message message, Channel channel) throws Exception {
byte[] body = message.getBody();
System.out.println("receive msg : " + new String(body));
channel.basicAck(message.getMessageProperties().getDeliveryTag(), false); //确认消息成功消费
}
});
return container;
}
}
