Dependencies for Spring Integration Amqp in Spring Boot

Dependencies for Spring Integration Amqp in Spring Boot

I had to add the following dependencies to resolve the classes in question (the last in the list did it, using latest spring initalizr, spring-boot 2.0.5)

dependencies {
    implementation(org.springframework.boot:spring-boot-starter-amqp)
    implementation(org.springframework.boot:spring-boot-starter-integration)
    testImplementation(org.springframework.boot:spring-boot-starter-test)

    compile org.springframework.integration:spring-integration-amqp
}

To be fair, this answer was already given, just not for gradle.

I am using gradle 4.10.2 on a linux machine, spring-boot initialzr with the options RabbitMQ and Spring-Integration. Here are the changed files:

build.gradle

buildscript {
    ext {
        springBootVersion = 2.0.5.RELEASE
    }
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath(org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion})
    }
}

apply plugin: java
apply plugin: eclipse
apply plugin: org.springframework.boot
apply plugin: io.spring.dependency-management

group = com.example
version = 0.0.1-SNAPSHOT
sourceCompatibility = 1.8

repositories {
    mavenCentral()
}


dependencies {
    implementation(org.springframework.boot:spring-boot-starter-amqp)
    implementation(org.springframework.boot:spring-boot-starter-integration)
    testImplementation(org.springframework.boot:spring-boot-starter-test)

    compile org.springframework.integration:spring-integration-amqp
}

Implementation of Example 12.2.1 Configuring with Java Configuration from the Spring Integration docs:

package com.example.integrationamqp;

import org.springframework.amqp.rabbit.connection.ConnectionFactory;
import org.springframework.amqp.rabbit.listener.SimpleMessageListenerContainer;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.boot.WebApplicationType;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.context.annotation.Bean;
import org.springframework.integration.amqp.inbound.AmqpInboundChannelAdapter;
import org.springframework.integration.amqp.inbound.AmqpInboundGateway;
import org.springframework.integration.annotation.ServiceActivator;
import org.springframework.integration.channel.DirectChannel;
import org.springframework.integration.handler.AbstractReplyProducingMessageHandler;
import org.springframework.messaging.Message;
import org.springframework.messaging.MessageChannel;
import org.springframework.messaging.MessageHandler;
import org.springframework.messaging.MessagingException;



@SpringBootApplication
public class IntegrationAmqpApplication {

     public static void main(String[] args) {
        new SpringApplicationBuilder(IntegrationAmqpApplication.class)
                .web(WebApplicationType.NONE)
                .run(args);
    }

    @Bean
    public MessageChannel amqpInputChannel() {
        return new DirectChannel();
    }

    @Bean
    public AmqpInboundChannelAdapter inbound(SimpleMessageListenerContainer listenerContainer,
                                             @Qualifier(amqpInputChannel) MessageChannel channel) {
        AmqpInboundChannelAdapter adapter = new AmqpInboundChannelAdapter(listenerContainer);
        adapter.setOutputChannel(channel);
        return adapter;
    }

    @Bean
    public SimpleMessageListenerContainer container(ConnectionFactory connectionFactory) {
        SimpleMessageListenerContainer container =
                new SimpleMessageListenerContainer(connectionFactory);
        container.setQueueNames(foo);
        container.setConcurrentConsumers(2);
        // ...
        return container;
    }

    @Bean
    @ServiceActivator(inputChannel = amqpInputChannel)
    public MessageHandler handler() {
        return new MessageHandler() {

            @Override
            public void handleMessage(Message<?> message) throws MessagingException {
                System.out.println(message.getPayload());
            }

        };
    }
}

Add this dependency:

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

And are you sure you have this one?:

<groupId>org.springframework.integration</groupId>
<artifactId>spring-integration-amqp</artifactId>
