SpringBoot迅速整合Rabbitmq

SpringBoot整合Rabbitmq其實只需要三步

一、加入Rabbitmq的相關依賴

pom.xml裏用到的jar依賴：

        <!--rabbitmq-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-amqp</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

在application.properties文件中加入配置：

#spring.application.name=callback-gateway
#spring.rabbitmq.host=111.111.111.111
#spring.rabbitmq.port=5672
#spring.rabbitmq.username=username
#spring.rabbitmq.password=password

或者配置application.yml：

server:
  port: 8021
spring:
  #給項目來個名字
  application:
    name: rabbitmq-provider
  #配置rabbitMq 服務器
  rabbitmq:
    host: 127.0.0.1
    port: 5672
    username: root
    password: root
    #虛擬host 可以不設置,使用server默認host
    virtual-host: JCcccHost

二、定義並設置隊列Queue、交換機Exchange和路由鍵RoutingKey的綁定關係。

import org.springframework.amqp.core.Binding;
import org.springframework.amqp.core.BindingBuilder;
import org.springframework.amqp.core.DirectExchange;
import org.springframework.amqp.core.Queue;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
 
/**
 * @Author : johny
 **/
@Configuration
public class DirectRabbitConfig {
 
    //隊列 起名：TestDirectQueue
    @Bean
    public Queue TestDirectQueue() {
        return new Queue("TestDirectQueue",true);
    }
 
    //Direct交換機 起名：TestDirectExchange
    @Bean
    DirectExchange TestDirectExchange() {
        return new DirectExchange("TestDirectExchange");
    }
 
    //綁定  將隊列和交換機綁定, 並設置用於匹配鍵：TestDirectRouting
    @Bean
    Binding bindingDirect() {
        return BindingBuilder.bind(TestDirectQueue()).to(TestDirectExchange()).with("TestDirectRouting");
    }
}

三、編寫生產者和消費者的代碼

（1）生產者

@GetMapping("/sendMessage1")
    public String sendMessage1() {
        String messageId = String.valueOf(UUID.randomUUID());
        String messageData = "message: M A N ";
        String createTime = LocalDateTime.now().format(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"));
        Map<String, Object> manMap = new HashMap<>();
        manMap.put("messageId", messageId);
        manMap.put("messageData", messageData);
        manMap.put("createTime", createTime);
        rabbitTemplate.convertAndSend("testExchange", "TestDirectRouting", manMap);
        return "ok";
}

(2)消費者

import org.springframework.amqp.rabbit.annotation.RabbitHandler;
import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;
import java.util.Map;
 
/**
 * @Author : JCccc
 * @CreateTime : 2019/9/3
 * @Description :
 **/
@Component
@RabbitListener(queues = "TestDirectQueue")
public class TopicManReceiver {
 
    @RabbitHandler
    public void process(Map testMessage) {
        System.out.println("TopicManReceiver消費者收到消息  : " + testMessage.toString());
    }
}
