rabbitmq.port=5672
rabbitmq.username=heima

发送消息

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:spring/spring-rabbitmq.xml")
public class ProducerTest {
@Autowired
private RabbitTemplate rabbitTemplate;
/**
* 只发队列消息
* 默认交换机类型为 direct
* 交换机的名称为空，路由键为队列的名称
*/
@Test
public void queueTest(){
//路由键与队列同名
rabbitTemplate.convertAndSend("spring_queue", "只发队列spring_queue的消息。");
}
/**
* 发送广播
* 交换机类型为 fanout
* 绑定到该交换机的所有队列都能够收到消息
*/
@Test
public void fanoutTest(){
/**
* 参数1：交换机名称
* 参数2：路由键名（广播设置为空）
* 参数3：发送的消息内容
*/
rabbitTemplate.convertAndSend("spring_fanout_exchange", "", "发送到spring_fanout_exchange交换机的广播消息");
}
/**

* 交换机类型为 topic
* 匹配路由键的通配符，*表示一个单词，#表示多个单词

/**

rabbitmq.port=5672
rabbitmq.username=heima
rabbitmq.password=heima

消息监听器
1）队列监听器
创建 spring-rabbitmq-consumer\src\main\java\com\itheima\rabbitmq\listener\SpringQueueListener.java
public class SpringQueueListener implements MessageListener {
public void onMessage(Message message) {
try {
String msg = new String(message.getBody(), "utf-8");
System.out.printf("接收路由名称为：%s，路由键为：%s，队列名为：%s的消息：%s \n",
message.getMessageProperties().getReceivedExchange(),
message.getMessageProperties().getReceivedRoutingKey(),
message.getMessageProperties().getConsumerQueue(),
msg);
} catch (Exception e) {
e.printStackTrace();
}
}
}
2）广播监听器1
创建 spring-rabbitmq-consumer\src\main\java\com\itheima\rabbitmq\listener\FanoutListener1.java
public class FanoutListener1 implements MessageListener {
public void onMessage(Message message) {
try {
String msg = new String(message.getBody(), "utf-8");
System.out.printf("广播监听器1：接收路由名称为：%s，路由键为：%s，队列名为：%s的消息：%s \n",
message.getMessageProperties().getReceivedExchange(),
message.getMessageProperties().getReceivedRoutingKey(),
message.getMessageProperties().getConsumerQueue(),
msg);
} catch (Exception e) {
e.printStackTrace();
}
}
}
3）广播监听器2
创建 spring-rabbitmq-consumer\src\main\java\com\itheima\rabbitmq\listener\FanoutListener2.java
public class FanoutListener2 implements MessageListener {
public void onMessage(Message message) {
try {
String msg = new String(message.getBody(), "utf-8");
System.out.printf("广播监听器2：接收路由名称为：%s，路由键为：%s，队列名为：%s的消息：%s \n",
message.getMessageProperties().getReceivedExchange(),
message.getMessageProperties().getReceivedRoutingKey(),
message.getMessageProperties().getConsumerQueue(),
msg);
} catch (Exception e) {
e.printStackTrace();
}
}
}
4）星号通配符监听器
创建 spring-rabbitmq-consumer\src\main\java\com\itheima\rabbitmq\listener\TopicListenerStar.java
public class TopicListenerStar implements MessageListener {
public void onMessage(Message message) {
try {
String msg = new String(message.getBody(), "utf-8");
System.out.printf("通配符*监听器：接收路由名称为：%s，路由键为：%s，队列名为：%s的消息：%s \n",
message.getMessageProperties().getReceivedExchange(),
message.getMessageProperties().getReceivedRoutingKey(),
message.getMessageProperties().getConsumerQueue(),
msg);
} catch (Exception e) {
e.printStackTrace();
}
}
}
5）井号通配符监听器
创建 spring-rabbitmq-consumer\src\main\java\com\itheima\rabbitmq\listener\TopicListenerWell.java
public class TopicListenerWell implements MessageListener {
public void onMessage(Message message) {
try {
String msg = new String(message.getBody(), "utf-8");
System.out.printf("通配符#监听器：接收路由名称为：%s，路由键为：%s，队列名为：%s的消息：%s \n",
message.getMessageProperties().getReceivedExchange(),
message.getMessageProperties().getReceivedRoutingKey(),
message.getMessageProperties().getConsumerQueue(),
msg);
} catch (Exception e) {
e.printStackTrace();
}
}
}
6）井号通配符监听器2
创建 spring-rabbitmq-consumer\src\main\java\com\itheima\rabbitmq\listener\TopicListenerWell2.java
public class TopicListenerWell2 implements MessageListener {
public void onMessage(Message message) {
try {
String msg = new String(message.getBody(), "utf-8");
System.out.printf("通配符#监听器2：接收路由名称为：%s，路由键为：%s，队列名为：%s的消息：%s \n",
message.getMessageProperties().getReceivedExchange(),
message.getMessageProperties().getReceivedRoutingKey(),
message.getMessageProperties().getConsumerQueue(),
msg);
} catch (Exception e) {
