1.pom中添加相關的starter依賴。
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-amqp</artifactId>
</dependency>
2.配置文件中加入相關配置信息
#rabbitmq
spring.rabbitmq.host=127.0.0.1
spring.rabbitmq.port=5672
spring.rabbitmq.username=admin
spring.rabbitmq.password=admin
3.隊列的簡單使用。
先創建一個隊列。然後創建一個隊列的發送者(生產者)。在創建隊列的接收者(消費者)。
創建隊列
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.amqp.core.Queue;
@Configuration
public class RabbitConfig {
@Bean
public Queue Queue() {
return new Queue("hello");
}
}
生產者
import java.util.Date;
import org.springframework.amqp.core.AmqpTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
@Component
public class HelloSender {
@Autowired
private AmqpTemplate rabbitTemplate;
public void send() {
String context = "hello " + new Date();
System.out.println("Sender : " + context);
this.rabbitTemplate.convertAndSend("hello", context);
}
}
消費者
import org.springframework.amqp.rabbit.annotation.RabbitHandler;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;
@Component
@RabbitListener(queues = "hello")
public class HelloReceiver {
@RabbitHandler
public void process(String hello) {
System.out.println("Receiver : " + hello);
}
}
測試
在Controller中注入生產者,直接調用send方法即可。
@RequestMapping("/hello")
public String index() {
helloSender.send();
return "Hello World";
}
