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

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.getMessagePjsroperties().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

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 {
