Migration guide for Spring Cloud Azure 4.0

  • Article

This guide helps with migration to Spring Cloud Azure 4.0 from legacy Azure Spring libraries.

Introduction

We'll call libraries whose group ID and artifact ID follow the pattern com.azure.spring:spring-cloud-azure-* the modern libraries, and those with pattern com.azure.spring:azure-spring-boot-*, com.azure.spring:azure-spring-cloud-*, or com.azure.spring:azure-spring-integration-* the legacy libraries.

This guide will focus on side-by-side comparisons for similar configurations between the modern and legacy libraries.

Familiarity with com.azure.spring:azure-spring-boot-*, com.azure.spring:azure-spring-cloud-* or com.azure.spring:azure-spring-integration-* package is assumed.

If you're new to the Spring Cloud Azure 4.0 libraries, see the Spring Cloud Azure developer guide rather than this guide.

Migration benefits

A natural question to ask when considering whether to adopt a new version or library is its benefits. As Azure has matured and been embraced by a more diverse group of developers, we've been focused on learning the patterns and practices to best support developer productivity and to understand the gaps that the Spring Cloud Azure libraries have.

There were several areas of consistent feedback expressed across the Spring Cloud Azure libraries. The most important is that the libraries for different Azure services haven't enabled the complete set of configurations. Additionally, the inconsistency of project naming, artifact IDs, versions, and configurations made the learning curve steep.

To improve the development experience across Spring Cloud Azure libraries, a set of design guidelines was introduced to ensure that Spring Cloud Azure libraries have a natural and idiomatic feel with respect to the Spring ecosystem. Further details are available in the design doc for those interested.

Spring Cloud Azure 4.0 provides the shared experience across libraries integrating with different Spring projects, for example Spring Boot, Spring Integration, Spring Cloud Stream, and so on. The shared experience includes:

  • A unified BOM to include all Spring Cloud Azure 4.0 libraries.
  • A consistent naming convention for artifacts.
  • A unified way to configure credential, proxy, retry, cloud environment, and transport layer settings.
  • Supporting all the authenticating methods an Azure Service or Azure Service SDK supports.

Overview

This migration guide consists of the following sections:

  • Naming changes for Spring Cloud Azure 4.0
  • Artifact changes: renamed / added / deleted
  • Dependency changes
  • Authentication changes
  • Configuration properties
  • API breaking changes
  • Library changes

Naming changes

There has never been a consistent or official name to call all the Spring Cloud Azure libraries. Some of them were called Azure Spring Boot and some of them Spring on Azure. Since 4.0, we began to use the project name Spring Cloud Azure to represent all the Azure Spring libraries.

BOM

We used to ship two BOMs for our libraries, the azure-spring-boot-bom and azure-spring-cloud-dependencies, but we combined these two BOMs into one BOM since 4.0, the spring-cloud-azure-dependencies. Add an entry in the dependencyManagement section of your project to benefit from the dependency management.

<dependencyManagement>
  <dependencies>
    <dependency>
      <groupId>com.azure.spring</groupId>
      <artifactId>spring-cloud-azure-dependencies</artifactId>
      <version>5.18.0</version>
      <type>pom</type>
      <scope>import</scope>
    </dependency>
  </dependencies>
</dependencyManagement>

Note

If you're using Spring Boot 2.x, be sure to set the spring-cloud-azure-dependencies version to 4.19.0. For more information about the version used for this BOM, see Which Version of Spring Cloud Azure Should I Use.

Artifact changes: renamed / added / deleted

Group IDs are the same for modern and legacy Spring Cloud Azure libraries. They're all com.azure.spring. Artifact IDs for the modern Spring Cloud Azure libraries have changed. According to which Spring project it belongs to, Spring Boot, Spring Integration, or Spring Cloud Stream, the artifact IDs pattern could be spring-cloud-azure-starter-[service], spring-integration-azure-[service], or spring-cloud-azure-stream-binder-[service]. The legacy starters for each has an artifact ID following the pattern azure-spring-*. This provides a quick and accessible means to help understand, at a glance, whether you're using modern or legacy starters.

In the process of developing Spring Cloud Azure 4.0, we renamed some artifacts to make them follow the new naming conventions, deleted some artifacts so that the functionality could be put into a more appropriate artifact, and added some new artifacts to better serve some scenarios.

The following table shows the mappings between legacy artifact ID and modern artifact ID:

Dependencies changes

Some unnecessary dependencies were included in the legacy artifacts, which we've removed in the modern Spring Cloud Azure 4.0 libraries. Be sure to add the removed dependencies manually to your project to prevent crashes.

Libraries that have dependency changes include:

Authentication changes

Spring Cloud Azure 4.0 supports all the authentication methods that each Azure Service SDK supports. It enables you to configure a global token credential as well as providing the token credential at each service level. But a credential isn't required to configure Spring Cloud Azure 4.0 because it can apply the credential stored in a local developing environment or managed identity in Azure Services. Just be sure the principal has been granted sufficient permission to access the target Azure resources.

Note

When assign roles to the security principals to interact with Azure messaging services, the Data related roles are required to conduct messaging operations. For Azure Spring Apps Stream Event Hubs / Service Bus Binder libraries, Contributor role is required when the function of auto creating resources is needed. For more information, see Azure built-in roles.

A chained credential, the DefaultAzureCredential bean is auto-configured by default and will be used by all components if no more authentication information is specified. For more information, see the DefaultAzureCredential section of Azure Identity client library for Java.

Configuration properties

Properties migration

We've created an additional-spring-configuration-metadata.json file to smooth the property migration when using with spring-boot-properties-migrator. First, add the following property migrator to your application:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-properties-migrator</artifactId>
    <scope>runtime</scope>
</dependency>

Or, if you’re using Gradle:

runtime("org.springframework.boot:spring-boot-properties-migrator")

If you run the app, it will identify the properties that are no longer managed by Spring Cloud Azure. If there's a replacement, it will temporarily remap the property for you with a warning. If there isn’t a replacement, an error report will give you more information. Either way, the configuration has to be updated and the dependency removed once you've updated the configuration.

Before you move on, it's a good idea to use the search feature of your IDE to double-check that you aren’t using one of the properties you’ve migrated in an integration test.

Note

We've changed many configuration properties in this change. Using the spring-boot-properties-migrator will help smooth your migration.

Global configurations

The modern spring-cloud-azure-starter enables you to define properties that apply to all Azure SDKs in the namespace spring.cloud.azure. This feature wasn't supported in the legacy azure-spring-boot-starter. The global configurations can be divided into five categories, shown in the following table:

Prefix Description
spring.cloud.azure.client Configures the transport clients underneath each Azure SDK.
spring.cloud.azure.credential Configures how to authenticate with Microsoft Entra ID.
spring.cloud.azure.profile Configures the Azure cloud environment.
spring.cloud.azure.proxy Configures the proxy options, apply to all Azure SDK clients.
spring.cloud.azure.retry Configures the retry options, apply to all Azure SDK clients. The retry options have supported part of the SDKs, there’s no spring.cloud.azure.cosmos.retry.

For a full list of configurations, see Spring Cloud Azure configuration properties.

  • Removed properties from spring-cloud-azure-starter-keyvault-secrets

azure.keyvault.allow-telemetry azure.keyvault.order

The following points you should pay your attention to:

  1. All configuration property names changed the prefix from azure.keyvault to spring.cloud.azure.keyvault.secret.
  2. spring.cloud.azure.keyvault.secret.enabled is used to enable all Key Vault Secret features, include configure Key Vault secret client beans(like SecretClient and SecretAsyncClient) and add KeyVaultPropertySource in ConfigurableEnvironment.
  3. spring.cloud.azure.keyvault.secret.property-source-enabled is used to enable all KeyVaultPropertySource. It will take effect only when spring.cloud.azure.keyvault.secret.enabled=true.
  4. For Azure common properties(like client, proxy, retry, credential, profile) and Key Vault properties(like endpoint, service-version). If spring.cloud.azure.keyvault.secret.property-sources[n].PROPERTY_NAME isn't configured, spring.cloud.azure.keyvault.secret.PROPERTY_NAME will be used.
  5. spring.cloud.azure.keyvault.secret.property-sources[n].resource is specific to a unique Azure resource, so if it's not configured, it won't get value from other places.

  • Drop APIs ServiceBusQueueOperation#setCheckpointConfig and ServiceBusTopicOperation#setCheckpointConfig. To set the checkpoint configuration for the inbound channel adapter, users can call the method ServiceBusContainerProperties#setAutoComplete instead. To disable the auto-complete mode is equivalent to MANUAL checkpoint mode and to enable it will trigger the RECORD mode.
  • Drop APIs ServiceBusQueueOperatio#setClientConfig and ServiceBusTopicOperation#setClientConfig. To configure the underlying ServiceBusProcessorClient used by the inbound channel adapter, users can use ServiceBusContainerProperties instead.
  • Drop CompletableFuture support in ServiceBusTemplate and DefaultMessageHandler, support Reactor instead.
  • Add new API of ServiceBusTemplate#setDefaultEntityType to specify the entity type, which is required when no bean of PropertiesSupplier&lt;String, ProducerProperties&gt; is provided for the ProducerProperties#entityType.
  • Drop message header AzureHeaders.RAW_ID. Use ServiceBusMessageHeaders.MESSAGE_ID instead.

        ServiceBusInboundChannelAdapter adapter = new ServiceBusInboundChannelAdapter(listenerContainer);
        adapter.setOutputChannel(inputChannel);
        return adapter;

}

  • DefaultMessageHandler sample code:

    Legacy code, taking queue as example:

    public class Demo {
    @Bean
    @ServiceActivator(inputChannel = "OUTPUT_CHANNEL_NAME")
    public MessageHandler queueMessageSender(ServiceBusQueueOperation queueOperation) {
        DefaultMessageHandler handler = new DefaultMessageHandler("QUEUE_NAME", queueOperation);
        handler.setSendCallback(new ListenableFutureCallback<Void>() {
            @Override
            public void onSuccess(Void result) {
                LOGGER.info("Message was sent successfully.");
            }
            @Override
            public void onFailure(Throwable ex) {
                LOGGER.info("There was an error sending the message.");
            }
        });
        return handler;
    }
}

    Modern code:

    public class Demo {

    @Bean
    @ServiceActivator(inputChannel = "OUTPUT_CHANNEL_NAME")
    public MessageHandler queueMessageSender(ServiceBusTemplate serviceBusTemplate) {
        serviceBusTemplate.setDefaultEntityType(ServiceBusEntityType.QUEUE);
        DefaultMessageHandler handler = new DefaultMessageHandler("QUEUE_NAME", serviceBusTemplate);
        handler.setSendCallback(new ListenableFutureCallback<Void>() {
            @Override
            public void onSuccess(Void result) {
                LOGGER.info("Message was sent successfully for {}.", "QUEUE_NAME");

From azure-spring-integration-servicebus to spring-integration-azure-servicebus

This guide is intended to assist in the migration to spring-integration-azure-servicebus from version 2 of azure-spring-integration-servicebus.

  • For an overview of the changes in 4.0, see the Introduction and Migration benefits sections.
  • To learn more about the strategy changes in the project naming, see the Naming changes section.
  • To learn how to use one BOM for all Spring Cloud Azure libraries, see the BOM section.

API changes

  • Drop ServiceBusQueueOperation and ServiceBusTopicOperation with the subscribing function moved to class ServiceBusMessageListenerContainer and the sending function moved to ServiceBusTemplate.
  • Drop ServiceBusQueueInboundChannelAdapter and ServiceBusTopicInboundChannelAdapter, and move the functionality to listen to a Service Bus queue/topic entity to ServiceBusInboundChannelAdapter.
  • Change the constructor from ServiceBusQueueInboundChannelAdapter(String, SubscribeByGroupOperation, String) to ServiceBusInboundChannelAdapter(ServiceBusMessageListenerContainer) and ServiceBusInboundChannelAdapter(ServiceBusMessageListenerContainer, ListenerMode).
  • Change the constructor from ServiceBusTopicInboundChannelAdapter(String, SubscribeByGroupOperation, String) to ServiceBusInboundChannelAdapter(ServiceBusMessageListenerContainer) and ServiceBusInboundChannelAdapter(ServiceBusMessageListenerContainer, ListenerMode).
  • Drop APIs ServiceBusQueueOperation#setCheckpointConfig and ServiceBusTopicOperation#setCheckpointConfig. To set the checkpoint configuration for the inbound channel adapter, users can call the method ServiceBusContainerProperties#setAutoComplete instead. To disable the auto-complete mode is equivalent to MANUAL checkpoint mode and to enable it will trigger the RECORD mode.
  • Drop APIs ServiceBusQueueOperation#setClientConfig and ServiceBusTopicOperation#setClientConfig. To configure the underlying ServiceBusProcessorClient used by the inbound channel adapter, users can use ServiceBusContainerProperties instead.
  • Drop CompletableFuture support in ServiceBusTemplate and DefaultMessageHandler, support Reactor instead.
  • Add new API of ServiceBusTemplate#setDefaultEntityType to specify the entity type, which is required when no bean of PropertiesSupplier&lt;String, ProducerProperties&gt; is provided for the ProducerProperties#entityType.
  • Drop message header AzureHeaders.RAW_ID. Use ServiceBusMessageHeaders.MESSAGE_ID instead.

If you use security principals instead of connection strings, in versions before 4.0 the application will firstly connect to Azure Resource Manager (ARM) with the provided security principal, and then retrieve the connection string of the specified namespace with ARM. In the end the application uses the retrieved connection string to connect to Azure Event Hubs. In this way the provided security principal should be granted with the Contributor role to retrieve of the associated Azure Event Hubs namespace.

For Azure Spring Apps 4.0, we provide two ways of leveraging security principals for authentication. One is still using the principals to connect to ARM and retrieve the connection strings where the Contributor role is required for the principals. The other leverages security principals to authenticate to Microsoft Entra ID and then connect to Azure Event Hubs directly. In this case, the Contributor role isn't necessary anymore, while other Data related roles are required for messaging operations. To make sure the security principal has been granted the sufficient permission to access the Azure resource, see Authorize access with Microsoft Entra ID.

For authentication based on ARM, taking service principal as example, configuration migration is listed the follows, where the assigned role should not change:

Legacy configuration:

spring:
  cloud:
    azure:
      client-id: ${AZURE_CLIENT_ID}
      client-secret: ${AZURE_CLIENT_SECRET}
      tenant-id: <tenant>
      resource-group: ${EVENTHUB_RESOURCE_GROUP}
      eventhub:
        namespace: ${EVENTHUB_NAMESPACE}

Note

The values allowed for tenant-id are: common, organizations, consumers, or the tenant ID. For more information about these values, see the Used the wrong endpoint (personal and organization accounts) section of Error AADSTS50020 - User account from identity provider does not exist in tenant. For information on converting your single-tenant app, see Convert single-tenant app to multitenant on Microsoft Entra ID.

Modern configuration, properties for Azure subscription ID and resource group are required:

spring:
  cloud:
    azure:
      credential:
        client-id: ${AZURE_CLIENT_ID}
        client-secret: ${AZURE_CLIENT_SECRET}
      profile:
        tenant-id: <tenant>
        subscription-id: ${AZURE_SUBSCRIPTION_ID}
      eventhubs:
        namespace: ${EVENTHUB_NAMESPACE}
        resource:
          resource-group: ${RESOURCE_GROUP}

Note

The values allowed for tenant-id are: common, organizations, consumers, or the tenant ID. For more information about these values, see the Used the wrong endpoint (personal and organization accounts) section of Error AADSTS50020 - User account from identity provider does not exist in tenant. For information on converting your single-tenant app, see Convert single-tenant app to multitenant on Microsoft Entra ID.

You can also migrate to authenticate and authorize with Microsoft Entra ID directly without making a detour to ARM. Make sure to grant the security principal necessary Data roles for messaging operations. The configuration examples of the service principal and the managed identity are listed the follows:

  • With a service principal

    spring:
  cloud:
    azure:
      credential:
        client-id: ${AZURE_CLIENT_ID}
        client-secret: ${AZURE_CLIENT_SECRET}
      profile:
        tenant-id: <tenant>
      eventhubs:
        namespace: ${EVENTHUB_NAMESPACE}

Note

The values allowed for tenant-id are: common, organizations, consumers, or the tenant ID. For more information about these values, see the Used the wrong endpoint (personal and organization accounts) section of Error AADSTS50020 - User account from identity provider does not exist in tenant. For information on converting your single-tenant app, see Convert single-tenant app to multitenant on Microsoft Entra ID.

  • With a managed identity

    spring:
  cloud:
    azure:
      credential:
        managed-identity-enabled: true
        client-id: ${AZURE_MANAGED_IDENTITY_CLIENT_ID} # Only needed when using a user-assigned managed identity
      eventhubs:
        namespace: ${EVENTHUB_NAMESPACE}

For more information about these values, see the Used the wrong endpoint (personal and organization accounts) section of Error AADSTS50020 - User account from identity provider does not exist in tenant. For information on converting your single-tenant app, see Convert single-tenant app to multitenant on Microsoft Entra ID.

You can also migrate to authenticate and authorize with Microsoft Entra ID directly without making a detour to ARM. Make sure to grant the security principal necessary Data roles for messaging operations. The configuration examples of the service principal and the managed identity are listed the follows:

        client-secret: ${AZURE_CLIENT_SECRET}
      profile:
        tenant-id: <tenant>
      servicebus:
        namespace: ${SERVICEBUS_NAMESPACE}
