代码方式
第一步方式导入依赖的方式
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<!--AMQP依赖,包含RabbitMQ-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-amqp</artifactId>
</dependency>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<scope>test</scope>
</dependency>
</dependencies>
原理,mq需要消费者(Publisher)发送消息,服务方式(Consumer)接受消息方式
yml 配置方式
spring:
rabbitmq:
host: 192.168.36.128 #主机端口
port: 5672
virtual-host: / #虚拟主机
username: itcast
password: 123321
server:
port: 1020
Publisher 调用api 方式 RabbitTemplate
@Autowired
private RabbitTemplate rabbitTemplate;
@GetMapping ( "/testSimpleQueue" )
public void testSimpleQueue ( ) {
String queueName = "simple.queue" ;
for ( int i = 0 ; i < 50 ; i++ ) {
String message = "hello, spring amqp!" + i;
rabbitTemplate. convertAndSend ( queueName, message) ;
}
}
说明 rabbitTemplate.convertAndSend(queueName, message);
queueName 队列名称,如何找到队列名称,这个队列名称,mq自动创建,只需要在发送消息,在消息接受方有对应的队列 就可以
message 发送消息
Consumer 服务的接受方式
yml 配置方式
spring:
rabbitmq:
listener:
simple:
prefetch: 1
host: 192.168 .36 .128
port: 5672
virtual- host: /
username: itcast
password: 123321
server:
port: 1010
consumer 接收者代码
@Component
public class SpringRabbitListener {
@RabbitListener ( queues = "simple.queue" )
public void listenSimpleQueueMessage ( String msg) throws InterruptedException {
System . out. println ( "spring 1----------:【" + msg + "】" + LocalTime . now ( ) ) ;
Thread . sleep ( 20 ) ;
}
@RabbitListener ( queues = "simple.queue" )
public void listenSimpleQueueMessageTwo ( String msg) throws InterruptedException {
System . out. println ( "spring 2------:【" + msg + "】" + LocalTime . now ( ) ) ;
Thread . sleep ( 1000 ) ;
}
}
解释 RabbitListener 中的队列参数名称queues
