Spring Boot与JMS消息中间件的集成

Spring Boot与JMS消息中间件的集成

大家好，我是免费搭建查券返利机器人省钱赚佣金就用微赚淘客系统3.0的小编，也是冬天不穿秋裤，天冷也要风度的程序猿！今天我们来探讨一下如何在Spring Boot中集成JMS（Java Message Service）消息中间件。

一、JMS简介

JMS是Java平台中的一项消息传递API，用于在两个应用程序或分布式系统之间发送消息。它提供了一种异步通信机制，可以提高系统的可扩展性和解耦性。常见的JMS消息中间件包括ActiveMQ、RabbitMQ和IBM MQ。

二、Spring Boot集成ActiveMQ

1. 引入ActiveMQ依赖

在pom.xml文件中添加ActiveMQ的依赖：

<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-activemq</artifactId>
</dependency>
<dependency><groupId>org.apache.activemq</groupId><artifactId>activemq-broker</artifactId><version>5.16.3</version>
</dependency>

2. 配置ActiveMQ连接

在application.properties文件中配置ActiveMQ连接信息：

spring.activemq.broker-url=tcp://localhost:61616
spring.activemq.user=admin
spring.activemq.password=admin

3. 创建消息生产者

package cn.juwatech.jms;import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.stereotype.Component;@Component
public class MessageProducer {@Autowiredprivate JmsTemplate jmsTemplate;public void sendMessage(String destination, String message) {jmsTemplate.convertAndSend(destination, message);}
}

4. 创建消息消费者

package cn.juwatech.jms;import org.springframework.jms.annotation.JmsListener;
import org.springframework.stereotype.Component;@Component
public class MessageConsumer {@JmsListener(destination = "test.queue")public void receiveMessage(String message) {System.out.println("Received message: " + message);}
}

5. 启用JMS监听

在Spring Boot应用主类中添加@EnableJms注解：

package cn.juwatech;import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.jms.annotation.EnableJms;@SpringBootApplication
@EnableJms
public class JmsApplication {public static void main(String[] args) {SpringApplication.run(JmsApplication.class, args);}
}

三、Spring Boot集成RabbitMQ

1. 引入RabbitMQ依赖

在pom.xml文件中添加RabbitMQ的依赖：

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

2. 配置RabbitMQ连接

在application.properties文件中配置RabbitMQ连接信息：

spring.rabbitmq.host=localhost
spring.rabbitmq.port=5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest

3. 创建消息生产者

package cn.juwatech.rabbitmq;import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;@Component
public class RabbitMQProducer {@Autowiredprivate RabbitTemplate rabbitTemplate;public void sendMessage(String exchange, String routingKey, String message) {rabbitTemplate.convertAndSend(exchange, routingKey, message);}
}

4. 创建消息消费者

package cn.juwatech.rabbitmq;import org.springframework.amqp.rabbit.annotation.RabbitListener;
import org.springframework.stereotype.Component;@Component
public class RabbitMQConsumer {@RabbitListener(queues = "test.queue")public void receiveMessage(String message) {System.out.println("Received message: " + message);}
}

5. 配置RabbitMQ队列、交换机和绑定

package cn.juwatech.rabbitmq;import org.springframework.amqp.core.Binding;
import org.springframework.amqp.core.BindingBuilder;
import org.springframework.amqp.core.Queue;
import org.springframework.amqp.core.TopicExchange;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;@Configuration
public class RabbitMQConfig {@Beanpublic Queue queue() {return new Queue("test.queue", false);}@Beanpublic TopicExchange exchange() {return new TopicExchange("test.exchange");}@Beanpublic Binding binding(Queue queue, TopicExchange exchange) {return BindingBuilder.bind(queue).to(exchange).with("test.routingkey");}
}
