Reactive Messaging AMQP 1.0 Connector Reference Documentation

This guide is the companion from the Getting Started with AMQP 1.0. It explains in more details the configuration and usage of the AMQP connector for reactive messaging.

This documentation does not cover all the details of the connector. Refer to the SmallRye Reactive Messaging website for further details.

The AMQP connector allows Quarkus applications to send and receive messages using the AMQP 1.0 protocol. More details about the protocol can be found in the AMQP 1.0 specification. It’s important to note that AMQP 1.0 and AMQP 0.9.1 (implemented by RabbitMQ) are incompatible. Check Using RabbitMQ to get more details.

AMQP connector extension

To use the connector, you need to add the quarkus-messaging-amqp extension.

You can add the extension to your project using:

CLI
quarkus extension add quarkus-messaging-amqp
Maven
./mvnw quarkus:add-extension -Dextensions='quarkus-messaging-amqp'
Gradle
./gradlew addExtension --extensions='quarkus-messaging-amqp'

Or just add the following dependency to your project:

pom.xml
<dependency>
    <groupId>io.quarkus</groupId>
    <artifactId>quarkus-messaging-amqp</artifactId>
</dependency>
build.gradle
implementation("io.quarkus:quarkus-messaging-amqp")

Once added to your project, you can map channels to AMQP addresses by configuring the connector attribute:

# Inbound
mp.messaging.incoming.[channel-name].connector=smallrye-amqp

# Outbound
mp.messaging.outgoing.[channel-name].connector=smallrye-amqp
Fixação automática do conector

Se você tiver um único conector no classpath, poderá omitir a configuração do atributo connector. O Quarkus associa automaticamente os canais órfãos ao conector (único) encontrado no classpath. Os canais órfãos são canais de saída sem um consumidor downstream ou canais de entrada sem um produtor ascendente.

Esta ligação automática pode ser desativada utilizando:

quarkus.messaging.auto-connector-attachment=false

Configuring the AMQP Broker access

The AMQP connector connects to AMQP 1.0 brokers such as Apache ActiveMQ or Artemis. To configure the location and credentials of the broker, add the following properties in the application.properties:

amqp-host=amqp (1)
amqp-port=5672 (2)
amqp-username=my-username (3)
amqp-password=my-password (4)

mp.messaging.incoming.prices.connector=smallrye-amqp (5)
1 Configures the broker/router host name. You can do it per channel (using the host attribute) or globally using amqp-host
2 Configures the broker/router port. You can do it per channel (using the port attribute) or globally using amqp-port. The default is 5672.
3 Configures the broker/router username if required. You can do it per channel (using the username attribute) or globally using amqp-username.
4 Configures the broker/router password if required. You can do it per channel (using the password attribute) or globally using amqp-password.
5 Instructs the prices channel to be managed by the AMQP connector

In dev mode and when running tests, Dev Services for AMQP automatically starts an AMQP broker.

Receiving AMQP messages

Let’s imagine your application receives Message<Double>. You can consume the payload directly:

package inbound;

import org.eclipse.microprofile.reactive.messaging.Incoming;

import jakarta.enterprise.context.ApplicationScoped;

@ApplicationScoped
public class AmqpPriceConsumer {

    @Incoming("prices")
    public void consume(double price) {
        // process your price.
    }

}

Or, you can retrieve the Message<Double>:

package inbound;

import org.eclipse.microprofile.reactive.messaging.Incoming;
import org.eclipse.microprofile.reactive.messaging.Message;

import jakarta.enterprise.context.ApplicationScoped;
import java.util.concurrent.CompletionStage;

@ApplicationScoped
public class AmqpPriceMessageConsumer {

    @Incoming("prices")
    public CompletionStage<Void> consume(Message<Double> price) {
        // process your price.

        // Acknowledge the incoming message, marking the AMQP message as `accepted`.
        return price.ack();
    }

}

Inbound Metadata

Messages coming from AMQP contain an instance of IncomingAmqpMetadata in the metadata.

Optional<IncomingAmqpMetadata> metadata = incoming.getMetadata(IncomingAmqpMetadata.class);
metadata.ifPresent(meta -> {
    String address = meta.getAddress();
    String subject = meta.getSubject();
    boolean durable = meta.isDurable();
    // Use io.vertx.core.json.JsonObject
    JsonObject properties = meta.getProperties();
    // ...
});

Deserialization

The connector converts incoming AMQP Messages into Reactive Messaging Message<T> instances. T depends on the body of the received AMQP Message.

The AMQP Type System defines the supported types.

AMQP Body Type <T>

AMQP Value containing a AMQP Primitive Type

the corresponding Java type

AMQP Value using the Binary type

byte[]

AMQP Sequence

List

AMQP Data (with binary content) and the content-type is set to application/json

JsonObject

AMQP Data with a different content-type

byte[]

If you send objects with this AMQP connector (outbound connector), it gets encoded as JSON and sent as binary. The content-type is set to application/json. So, you can rebuild the object as follows:

import io.vertx.core.json.JsonObject;
//
@ApplicationScoped
public static class Consumer {

    List<Price> prices = new CopyOnWriteArrayList<>();

    @Incoming("from-amqp") (1)
    public void consume(JsonObject p) {   (2)
        Price price = p.mapTo(Price.class);  (3)
        prices.add(price);
    }

    public List<Price> list() {
        return prices;
    }
}
1 The Price instances are automatically encoded to JSON by the connector
2 You can receive it using a JsonObject
3 Then, you can reconstruct the instance using the mapTo method
The mapTo method uses the Quarkus Jackson mapper. Check this guide to learn more about the mapper configuration.

Acknowledgement

When a Reactive Messaging Message associated with an AMQP Message is acknowledged, it informs the broker that the message has been accepted.

Failure Management

If a message produced from an AMQP message is nacked, a failure strategy is applied. The AMQP connector supports six strategies:

  • fail - fail the application; no more AMQP messages will be processed (default). The AMQP message is marked as rejected.

  • accept - this strategy marks the AMQP message as accepted. The processing continues ignoring the failure. Refer to the accepted delivery state documentation.

  • release - this strategy marks the AMQP message as released. The processing continues with the next message. The broker can redeliver the message. Refer to the released delivery state documentation.

  • reject - this strategy marks the AMQP message as rejected. The processing continues with the next message. Refer to the rejected delivery state documentation.

  • modified-failed - this strategy marks the AMQP message as modified and indicates that it failed (with the delivery-failed attribute). The processing continues with the next message, but the broker may attempt to redeliver the message. Refer to the modified delivery state documentation

  • modified-failed-undeliverable-here - this strategy marks the AMQP message as modified and indicates that it failed (with the delivery-failed attribute). It also indicates that the application cannot process the message, meaning that the broker will not attempt to redeliver the message to this node. The processing continues with the next message. Refer to the modified delivery state documentation

Sending AMQP messages

Serialização

When sending a Message<T>, the connector converts the message into an AMQP Message. The payload is converted to the AMQP Message body.

T AMQP Message Body

primitive types or String

AMQP Value with the payload

Instant or UUID

AMQP Value using the corresponding AMQP Type

JsonObject or JsonArray

AMQP Data using a binary content. The content-type is set to application/json

io.vertx.mutiny.core.buffer.Buffer

AMQP Data using a binary content. No content-type set

Any other class

The payload is converted to JSON (using a Json Mapper). The result is wrapped into AMQP Data using a binary content. The content-type is set to application/json

If the message payload cannot be serialized to JSON, the message is nacked.

Outbound Metadata

When sending Messages, you can add an instance of OutgoingAmqpMetadata to influence how the message is going to be sent to AMQP. For example, you can configure the subjects, properties:

 OutgoingAmqpMetadata metadata = OutgoingAmqpMetadata.builder()
    .withDurable(true)
    .withSubject("my-subject")
    .build();

// Create a new message from the `incoming` message
// Add `metadata` to the metadata from the `incoming` message.
return incoming.addMetadata(metadata);

Dynamic address names

Sometimes it is desirable to select the destination of a message dynamically. In this case, you should not configure the address inside your application configuration file, but instead, use the outbound metadata to set the address.

For example, you can send to a dynamic address based on the incoming message:

String addressName = selectAddressFromIncommingMessage(incoming);
OutgoingAmqpMetadata metadata = OutgoingAmqpMetadata.builder()
    .withAddress(addressName)
    .withDurable(true)
    .build();

// Create a new message from the `incoming` message
// Add `metadata` to the metadata from the `incoming` message.
return incoming.addMetadata(metadata);
To be able to set the address per message, the connector is using an anonymous sender.

Acknowledgement

By default, the Reactive Messaging Message is acknowledged when the broker acknowledged the message. When using routers, this acknowledgement may not be enabled. In this case, configure the auto-acknowledgement attribute to acknowledge the message as soon as it has been sent to the router.

If an AMQP message is rejected/released/modified by the broker (or cannot be sent successfully), the message is nacked.

Back Pressure and Credits

The back-pressure is handled by AMQP credits. The outbound connector only requests the amount of allowed credits. When the amount of credits reaches 0, it waits (in a non-blocking fashion) until the broker grants more credits to the AMQP sender.

Configuring the AMQP address

You can configure the AMQP address using the address attribute:

mp.messaging.incoming.prices.connector=smallrye-amqp
mp.messaging.incoming.prices.address=my-queue

mp.messaging.outgoing.orders.connector=smallrye-amqp
mp.messaging.outgoing.orders.address=my-order-queue

If the address attribute is not set, the connector uses the channel name.

To use an existing queue, you need to configure the address, container-id and, optionally, the link-name attributes. For example, if you have an Apache Artemis broker configured with:

<queues>
    <queue name="people">
        <address>people</address>
        <durable>true</durable>
        <user>artemis</user>
    </queue>
</queues>

You need the following configuration:

mp.messaging.outgoing.people.connector=smallrye-amqp
mp.messaging.outgoing.people.durable=true
mp.messaging.outgoing.people.address=people
mp.messaging.outgoing.people.container-id=people

You may need to configure the link-name attribute, if the queue name is not the channel name:

mp.messaging.outgoing.people-out.connector=smallrye-amqp
mp.messaging.outgoing.people-out.durable=true
mp.messaging.outgoing.people-out.address=people
mp.messaging.outgoing.people-out.container-id=people
mp.messaging.outgoing.people-out.link-name=people

To use a MULTICAST queue, you need to provide the FQQN (fully-qualified queue name) instead of just the name of the queue:

mp.messaging.outgoing.people-out.connector=smallrye-amqp
mp.messaging.outgoing.people-out.durable=true
mp.messaging.outgoing.people-out.address=foo
mp.messaging.outgoing.people-out.container-id=foo

mp.messaging.incoming.people-out.connector=smallrye-amqp
mp.messaging.incoming.people-out.durable=true
mp.messaging.incoming.people-out.address=foo::bar # Note the syntax: address-name::queue-name
mp.messaging.incoming.people-out.container-id=bar
mp.messaging.incoming.people-out.link-name=people

More details about the AMQP Address model can be found in the Artemis documentation.

Execution model and Blocking processing

A Mensageria Reativa invoca seu método em um thread de E/S. Consulte a documentação da Arquitetura Reativa do Quarkus para obter mais detalhes sobre esse tópico. Mas, muitas vezes, você precisa combinar o envio de mensagens reativas com processamento blocante, como interações de banco de dados. Para isso, você precisa usar a anotação @Blocking indicando que o processamento está bloqueando e não deve ser executado no thread do chamador.

Por exemplo, o código a seguir ilustra como é possível armazenar conteúdos recebidos em uma base de dados usando o Hibernate com Panache:

import io.smallrye.reactive.messaging.annotations.Blocking;
import org.eclipse.microprofile.reactive.messaging.Incoming;

import jakarta.enterprise.context.ApplicationScoped;
import jakarta.transaction.Transactional;

@ApplicationScoped
public class PriceStorage {

    @Incoming("prices")
    @Transactional
    public void store(int priceInUsd) {
        Price price = new Price();
        price.value = priceInUsd;
        price.persist();
    }

}

Existem 2 anotações de @Blocking:

  1. io.smallrye.reactive.messaging.annotations.Blocking

  2. io.smallrye.common.annotation.Blocking

Eles têm o mesmo efeito. Portanto, você pode usar os dois. O primeiro fornece um ajuste mais refinado, como o pool de trabalho a ser usado e se ele preserva a ordem. O segundo, usado também com outros recursos reativos do Quarkus, usa o pool de trabalho padrão e preserva a ordem.

@RunOnVirtualThread

Para executar o processamento blocante em threads virtuais Java, consulte a documentação de suporte do Quarkus à Virtual Thread com Mensageria Reativa.

@Transactional

Se o seu método estiver anotado com @Transactional, será considerado blocante automaticamente, mesmo que o método não esteja anotado com @Blocking.

Customizing the underlying AMQP client

The connector uses the Vert.x AMQP client underneath. More details about this client can be found in the Vert.x website.

You can customize the underlying client configuration by producing an instance of AmqpClientOptions as follows:

@Produces
@Identifier("my-named-options")
public AmqpClientOptions getNamedOptions() {
  // You can use the produced options to configure the TLS connection
  PemKeyCertOptions keycert = new PemKeyCertOptions()
    .addCertPath("./tls/tls.crt")
    .addKeyPath("./tls/tls.key");
  PemTrustOptions trust = new PemTrustOptions().addCertPath("./tlc/ca.crt");
  return new AmqpClientOptions()
        .setSsl(true)
        .setPemKeyCertOptions(keycert)
        .setPemTrustOptions(trust)
        .addEnabledSaslMechanism("EXTERNAL")
        .setHostnameVerificationAlgorithm("") // Disables the hostname verification. Defaults is "HTTPS"
        .setConnectTimeout(30000)
        .setReconnectInterval(5000)
        .setContainerId("my-container");
}

This instance is retrieved and used to configure the client used by the connector. You need to indicate the name of the client using the client-options-name attribute:

mp.messaging.incoming.prices.client-options-name=my-named-options

If you experience frequent disconnections from the broker, the AmqpClientOptions can also be used to set a heartbeat if you need to keep the AMQP connection permanently. Some brokers might terminate the AMQP connection after a certain idle timeout. You can provide a heartbeat value which will be used by the Vert.x proton client to advertise the idle timeout when opening transport to a remote peer.

@Produces
@Identifier("my-named-options")
public AmqpClientOptions getNamedOptions() {
  // set a heartbeat of 30s (in milliseconds)
  return new AmqpClientOptions()
        .setHeartbeat(30000);
}

TLS Configuration

AMQP 1.0 Messaging extension integrates with the Quarkus TLS registry to configure the Vert.x AMQP client.

To configure the TLS for an AMQP 1.0 channel, you need to provide a named TLS configuration in the application.properties:

quarkus.tls.your-tls-config.trust-store.pem.certs=ca.crt,ca2.pem
# ...
mp.messaging.incoming.prices.tls-configuration-name=your-tls-config

Health reporting

If you use the AMQP connector with the quarkus-smallrye-health extension, it contributes to the readiness and liveness probes. The AMQP connector reports the readiness and liveness of each channel managed by the connector. At the moment, the AMQP connector uses the same logic for the readiness and liveness checks.

To disable health reporting, set the health-enabled attribute for the channel to false. On the inbound side (receiving messages from AMQP), the check verifies that the receiver is attached to the broker. On the outbound side (sending records to AMQP), the check verifies that the sender is attached to the broker.

Note that a message processing failures nacks the message, which is then handled by the failure-strategy. It is the responsibility of the failure-strategy to report the failure and influence the outcome of the checks. The fail failure strategy reports the failure, and so the check will report the fault.

Using RabbitMQ

This connector is for AMQP 1.0. RabbitMQ implements AMQP 0.9.1. RabbitMQ does not provide AMQP 1.0 by default, but there is a plugin for it. To use RabbitMQ with this connector, enable and configure the AMQP 1.0 plugin.

Despite the existence of the plugin, a few AMQP 1.0 features won’t work with RabbitMQ. Thus, we recommend the following configurations.

To receive messages from RabbitMQ:

  • Set durable to false

mp.messaging.incoming.prices.connector=smallrye-amqp
mp.messaging.incoming.prices.durable=false

To send messages to RabbitMQ:

  • set the destination address (anonymous sender are not supported)

  • set use-anonymous-sender to false

mp.messaging.outgoing.generated-price.connector=smallrye-amqp
mp.messaging.outgoing.generated-price.address=prices
mp.messaging.outgoing.generated-price.use-anonymous-sender=false

As a consequence, it’s not possible to change the destination dynamically (using message metadata) when using RabbitMQ.

Receiving Cloud Events

The AMQP connector supports Cloud Events. When the connector detects a structured or binary Cloud Events, it adds a IncomingCloudEventMetadata<T> into the metadata of the Message. IncomingCloudEventMetadata contains accessors to the mandatory and optional Cloud Event attributes.

If the connector cannot extract the Cloud Event metadata, it sends the Message without the metadata.

For more information on receiving Cloud Events, see Receiving Cloud Events in SmallRye Reactive Messaging documentation.

Sending Cloud Events

The AMQP connector supports Cloud Events. The connector sends the outbound record as Cloud Events if:

  • the message metadata contains an io.smallrye.reactive.messaging.ce.OutgoingCloudEventMetadata instance,

  • the channel configuration defines the cloud-events-type and cloud-events-source attributes.

For more information on sending Cloud Events, see Sending Cloud Events in SmallRye Reactive Messaging documentation.

Indicates if the AMQP broker managed by Quarkus Dev Services is shared. When shared, Quarkus looks for running containers using label-based service discovery. If a matching container is found, it is used, and so a second one is not started. Otherwise, Dev Services for AMQP starts a new container.

The discovery uses the quarkus-dev-service-amqp label. The value is configured using the service-name property.

Container sharing is only used in dev mode.

Environment variable: QUARKUS_AMQP_DEVSERVICES_SHARED

boolean

true

The value of the quarkus-dev-service-aqmp label attached to the started container. This property is used when shared is set to true. In this case, before starting a container, Dev Services for AMQP looks for a container with the quarkus-dev-service-amqp label set to the configured value. If found, it will use this container instead of starting a new one. Otherwise, it starts a new container with the quarkus-dev-service-amqp label set to the specified value.

This property is used when you need multiple shared AMQP brokers.

Configurar canais condicionalmente

Você pode configurar os canais usando um perfil específico. Assim, os canais só são configurados (e adicionados à aplicação) quando o perfil especificado é ativado.

Para conseguir isso, você precisa:

  1. Prefixar as entradas mp.messaging.[incoming|outgoing].$channel com %my-profile tal como %my-profile.mp.messaging.[incoming|outgoing].$channel.key=value

  2. Utilizar o @IfBuildProfile("my-profile") nos beans CDI que contêm anotações @Incoming(channel) e @Outgoing(channel) que só precisam ser ativadas quando o perfil é ativado.

Observe que as mensagens reativas verificam se o gráfico está completo. Portanto, ao usar essa configuração condicional, certifique-se de que a aplicação funcione com e sem o perfil ativado.

Note que esta abordagem também pode ser utilizada para alterar a configuração do canal com base num perfil.
