(1)、导入starter依赖
1 <dependency> 2 <groupId>org.springframework.boot</groupId> 3 <artifactId>spring-boot-starter-amqp</artifactId> 4 </dependency>
(2)、在配置文件中配置rabbitmq相关属性
1 spring.rabbitmq.host=192.168.205.128 2 spring.rabbitmq.port=5672 3 spring.rabbitmq.username=guest 4 spring.rabbitmq.password=guest
(3)、配置rabbitmq使用json进行消息的序列化(默认使用JDK进行消息的序列化)
1 package cn.coreqi.config; 2 3 import org.springframework.amqp.support.converter.Jackson2JsonMessageConverter; 4 import org.springframework.amqp.support.converter.MessageConverter; 5 import org.springframework.context.annotation.Bean; 6 import org.springframework.context.annotation.Configuration; 7 8 @Configuration 9 public class MyAMQPConfig { 10 11 //使用JSON进行消息的序列化 12 @Bean 13 public MessageConverter messageConverter(){ 14 return new Jackson2JsonMessageConverter(); 15 } 16 17 }
(4)主程序类添加@EnableRabbit注解开启基于注解的RabbltMQ模式
1 package cn.coreqi; 2 3 import org.springframework.amqp.rabbit.annotation.EnableRabbit; 4 import org.springframework.boot.SpringApplication; 5 import org.springframework.boot.autoconfigure.SpringBootApplication; 6 7 @SpringBootApplication 8 @EnableRabbit 9 public class SpringbootrabbitmqApplication { 10 11 public static void main(String[] args) { 12 SpringApplication.run(SpringbootrabbitmqApplication.class, args); 13 } 14 15 }
(5)、使用AmqpAdmin创建和删除Queue、Exchange、Binding,使用RabbitTemplate发送和接收消息
1 @Autowired 2 private RabbitOperations rabbitOperations; 3 @Autowired 4 private AmqpAdmin amqpAdmin; 5 6 public void send(){ 7 amqpAdmin.declareExchange(new DirectExchange("userExchange")); //声明交换器 new DirectExchange("ExchangeName") 8 amqpAdmin.declareQueue(new Queue("userQueue",true)); //声明队列 new Queue("QueueName",是否持久化) 9 amqpAdmin.declareBinding(new Binding("userQueue", Binding.DestinationType.QUEUE,"userExchange","user",null)); //声明binding new Binding(目的地(队列名称),绑定类型,交换器名称,路由键,参数列表) 10 rabbitOperations.convertAndSend("userExchange","user",new User(1,"fanqi","123456",1)); //ExchangeName,routing-key,object 11 } 12 13 public User receive(){ //反序列化时要保证Bean具有无参构造器 14 return (User) rabbitOperations.receiveAndConvert("userQueue"); 15 }
(6)、监听消息队列,在service层所需方法上添加@RabbitListener注解,当队列中添加了新消息,此方法将会被调用。
1 package cn.coreqi.service; 2 3 import cn.coreqi.entities.User; 4 import com.fasterxml.jackson.databind.ObjectMapper; 5 import org.springframework.amqp.core.Message; 6 import org.springframework.amqp.rabbit.annotation.RabbitListener; 7 import org.springframework.stereotype.Service; 8 9 import java.io.IOException; 10 11 @Service 12 public class UserService { 13 @RabbitListener(queues = "userQueue") 14 public void receive(User user){ 15 System.out.println(user.toString()); 16 } 17 @RabbitListener(queues = "userQueue") 18 public void receive1(Message message) throws IOException { 19 ObjectMapper mapper = new ObjectMapper(); 20 User user = mapper.readValue(message.getBody(), User.class); 21 System.out.println(user.toString()); 22 } 23 }
