Azure ServiceBus

Since Camel 3.12

Both producer and consumer are supported

The azure-servicebus component that integrates Azure ServiceBus. Azure ServiceBus is a fully managed enterprise integration message broker. Service Bus can decouple applications and services. Service Bus offers a reliable and secure platform for asynchronous transfer of data and state. Data is transferred between different applications and services using messages.

Prerequisites

You must have a valid Windows Azure Storage account. More information is available at Azure Documentation Portal.

Configuring Options

Camel components are configured on two separate levels:

  • component level

  • endpoint level

Configuring Component Options

At the component level, you set general and shared configurations that are, then, inherited by the endpoints. It is the highest configuration level.

For example, a component may have security settings, credentials for authentication, urls for network connection and so forth.

Some components only have a few options, and others may have many. Because components typically have pre-configured defaults that are commonly used, then you may often only need to configure a few options on a component; or none at all.

You can configure components using:

  • the Component DSL.

  • in a configuration file (application.properties, *.yaml files, etc).

  • directly in the Java code.

Configuring Endpoint Options

You usually spend more time setting up endpoints because they have many options. These options help you customize what you want the endpoint to do. The options are also categorized into whether the endpoint is used as a consumer (from), as a producer (to), or both.

Configuring endpoints is most often done directly in the endpoint URI as path and query parameters. You can also use the Endpoint DSL and DataFormat DSL as a type safe way of configuring endpoints and data formats in Java.

A good practice when configuring options is to use Property Placeholders.

Property placeholders provide a few benefits:

  • They help prevent using hardcoded urls, port numbers, sensitive information, and other settings.

  • They allow externalizing the configuration from the code.

  • They help the code to become more flexible and reusable.

The following two sections list all the options, firstly for the component followed by the endpoint.

Component Options

The Azure ServiceBus component supports 29 options, which are listed below.

Name Description Default Type

amqpRetryOptions (common)

Sets the retry options for Service Bus clients. If not specified, the default retry options are used.

AmqpRetryOptions

amqpTransportType (common)

Sets the transport type by which all the communication with Azure Service Bus occurs. Default value is AMQP.

Enum values:

  • Amqp

  • AmqpWebSockets

AMQP

AmqpTransportType

clientOptions (common)

Sets the ClientOptions to be sent from the client built from this builder, enabling customization of certain properties, as well as support the addition of custom header information.

ClientOptions

configuration (common)

The component configurations.

ServiceBusConfiguration

headerFilterStrategy (common)

To use a custom HeaderFilterStrategy to filter Service Bus application properties to and from Camel message headers.

HeaderFilterStrategy

proxyOptions (common)

Sets the proxy configuration to use for ServiceBusSenderAsyncClient. When a proxy is configured, AMQP_WEB_SOCKETS must be used for the transport type.

ProxyOptions

serviceBusType (common)

Required The service bus type of connection to execute. Queue is for typical queue option and topic for subscription based model.

Enum values:

  • queue

  • topic

queue

ServiceBusType

bridgeErrorHandler (consumer)

Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions (if possible) occurred while the Camel consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. Important: This is only possible if the 3rd party component allows Camel to be alerted if an exception was thrown. Some components handle this internally only, and therefore bridgeErrorHandler is not possible. In other situations we may improve the Camel component to hook into the 3rd party component and make this possible for future releases. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored.

false

boolean

consumerOperation (consumer)

Sets the desired operation to be used in the consumer.

Enum values:

  • receiveMessages

  • peekMessages

receiveMessages

ServiceBusConsumerOperationDefinition

disableAutoComplete (consumer)

false

boolean

maxAutoLockRenewDuration (consumer)

Sets the amount of time to continue auto-renewing the lock. Setting ZERO disables auto-renewal. For ServiceBus receive mode (RECEIVE_AND_DELETE RECEIVE_AND_DELETE), auto-renewal is disabled.

5m

Duration

peekNumMaxMessages (consumer)

Set the max number of messages to be peeked during the peek operation.

Integer

prefetchCount (consumer)

Sets the prefetch count of the receiver. For both PEEK_LOCK PEEK_LOCK and RECEIVE_AND_DELETE RECEIVE_AND_DELETE receive modes the default value is 1. Prefetch speeds up the message flow by aiming to have a message readily available for local retrieval when and before the application asks for one using receive message. Setting a non-zero value will prefetch that number of messages. Setting the value to zero turns prefetch off.

int

receiverAsyncClient (consumer)

Autowired Sets the receiverAsyncClient in order to consume messages by the consumer.

ServiceBusReceiverAsyncClient

Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.

Authentication Information

You have three different Credential Types: AZURE_IDENTITY, TOKEN_CREDENTIAL and CONNECTION_STRING. You can also provide a client instance yourself. To use this component, you have three options to provide the required Azure authentication information:

CONNECTION_STRING:

  • Provide connectionString string it is the simplest option to get started.

TOKEN_CREDENTIAL:

  • Provide an implementation of com.azure.core.credential.TokenCredential into the Camel’s Registry, e.g., using the com.azure.identity.DefaultAzureCredentialBuilder().build(); API. See the documentation here about Azure-AD authentication.

AZURE_IDENTITY:

  • This will use com.azure.identity.DefaultAzureCredentialBuilder().build(); instance. This will follow the Default Azure Credential Chain. See the documentation here about Azure-AD authentication.

Client instance:

  • You can provide a com.azure.messaging.servicebus.ServiceBusSenderAsyncClient for sending message and/or com.azure.messaging.servicebus.ServiceBusReceiverAsyncClient to receive messages. If you provide the instances, they will be autowired.

Message Body

In the producer, this component accepts message body of String, byte[] and BinaryData types or List<String>, List<byte[]> and List<BinaryData> to send batch messages.

In the consumer, the returned message body will be of type `String.

Azure ServiceBus Producer operations

Operation Description

sendMessages

Azure ServiceBus Consumer operations

Operation Description

receiveMessages

Receives an <b>infinite</b> stream of messages from the Service Bus entity.

peekMessages

Reads the next batch of active messages without changing the state of the receiver or the message source.
