Belajar RabbitMQ - Cara Membuat RabbitMQ Publisher

RabbitMQ Publisher merupakan aplikasi atau komponen yang mengirimkan pesan ke message broker. Pastikan kalian sudah membuat RabbitMQ Consumer untuk menerima pesan yang akan kalian kirimkan.

Berikut ini merupakan contoh source code untuk membuat RabbitMQ Publisher dengan menggunakan Spring Boot 3.3.2.

<dependencies>
    <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>

    <dependency>
        <groupId>org.projectlombok</groupId>
        <artifactId>lombok</artifactId>
        <optional>true</optional>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
    <dependency>
        <groupId>org.springframework.amqp</groupId>
        <artifactId>spring-rabbit-test</artifactId>
        <scope>test</scope>
    </dependency>
</dependencies>
#Server
server.port=8081
server.servlet.context-path=/api-v1

#Konfigurasi RabbitMQ
spring.rabbitmq.host=localhost
spring.rabbitmq.port=5672
spring.rabbitmq.username=guest
spring.rabbitmq.password=guest

#QUEQUE
rabbit.queue-log=queue_log
rabbit.exchange-log=exchange_log
rabbit.routing-log=routing_log
PropertiesRabbit
@Getter
@Setter
@Component
@ConfigurationProperties(prefix = "rabbit")
public class PropertiesRabbit {
    private String queueLog;
    private String exchangeLog;
    private String routingLog;
}
ConfigRabbit

Mendefinisikan konfigurasi RabbitMQ, termasuk pembuatan queue dan exchange.

@Configuration
public class ConfigRabbit {

    @Autowired
    private PropertiesRabbit propertiesRabbit;

    @Bean
    public Queue queue(){
        return new Queue(propertiesRabbit.getQueueLog());
    }

    @Bean
    public TopicExchange exchange(){
        return new TopicExchange(propertiesRabbit.getExchangeLog());
    }

    @Bean
    public Binding binding(Queue queue, TopicExchange exchange){
        return BindingBuilder
                .bind(queue)
                .to(exchange)
                .with(propertiesRabbit.getRoutingLog());
    }

    @Bean
    public MessageConverter converter() {
        return new Jackson2JsonMessageConverter();
    }

    @Bean
    public RabbitTemplate rabbitTemplate(ConnectionFactory connectionFactory) {
        RabbitTemplate rabbitTemplate = new RabbitTemplate(connectionFactory);
        rabbitTemplate.setMessageConverter(converter());
        return rabbitTemplate;
    }
}
ApiController

Controller untuk mengirim pesan ke RabbitMQ menggunakan RabbitTemplate untuk mengirim pesan ke queue yang telah ditentukan.

@RestController
public class ApiController {
    @Autowired
    private PropertiesRabbit propertiesRabbit;

    @Autowired
    RabbitTemplate template;

    @PostMapping("/create")
    public ResponseEntity<String> create(@RequestBody String message) {

        template.convertAndSend(
                propertiesRabbit.getExchangeLog(),
                propertiesRabbit.getRoutingLog(),
                message);

        return ResponseEntity.ok("Pesan Berhasil Dikirim");
    }
}

Dengan mengikuti tutorial ini, Anda telah membuat aplikasi sederhana menggunakan RabbitMQ sebagai publisher.
