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.

PropertiesRabbit

import lombok.Getter;
import lombok.Setter;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;

@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.

ConfigRabbit

import org.springframework.amqp.core.*;
import org.springframework.amqp.rabbit.connection.ConnectionFactory;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.amqp.support.converter.Jackson2JsonMessageConverter;
import org.springframework.amqp.support.converter.MessageConverter;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@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.

ApiController

import id.aban.rabbit.config.PropertiesRabbit;
import org.springframework.amqp.rabbit.core.RabbitTemplate;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;

@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");
    }
}
