使用Spring Boot将消息发布到RabbitMQ(运行时提供的队列详细信息)的步骤如下:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-amqp</artifactId>
</dependency>
spring.rabbitmq.host=your_rabbitmq_host
spring.rabbitmq.port=your_rabbitmq_port
spring.rabbitmq.username=your_rabbitmq_username
spring.rabbitmq.password=your_rabbitmq_password
import org.springframework.amqp.core.Queue;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Configuration
public class RabbitMQConfig {
@Bean
public Queue queue() {
return new Queue("your_queue_name");
}
}
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
@Component
public class MessageSender {
private final RabbitTemplate rabbitTemplate;
private final Queue queue;
@Autowired
public MessageSender(RabbitTemplate rabbitTemplate, Queue queue) {
this.rabbitTemplate = rabbitTemplate;
this.queue = queue;
}
public void sendMessage(String message) {
rabbitTemplate.convertAndSend(queue.getName(), message);
}
}
sendMessage
方法即可发布消息到RabbitMQ队列:import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class MessageController {
private final MessageSender messageSender;
@Autowired
public MessageController(MessageSender messageSender) {
this.messageSender = messageSender;
}
@PostMapping("/send")
public void sendMessage(@RequestBody String message) {
messageSender.sendMessage(message);
}
}
以上步骤中,我们使用了Spring Boot的自动配置和依赖注入特性,通过配置文件连接到RabbitMQ,并创建了一个发送消息的消息队列和发送者。通过调用发送者的方法,将消息发布到RabbitMQ的指定队列中。
