Introduction

Azure Service Bus is a reliable messaging service that helps build scalable and distributed applications. In Spring Boot, you can send and receive messages efficiently using Azure Service Bus queues or topics. This guide explains the process, from configuration to message handling, along with practical examples to get you started.

Configuring Azure Service Bus in Spring Boot

Setting Up the Dependency

Add the spring-cloud-azure-starter-servicebus dependency to your pom.xml file or build.gradle to integrate Azure Service Bus with Spring Boot.

Maven

Gradle

Configuring Connection Properties

Add the Azure Service Bus connection string and related configurations to your application.yml or application.properties file.

Example (application.yml)

Sending Messages to Azure Service Bus

Use the ServiceBusSenderClient to send messages to a specific queue.

Code Example

Example Usage

Receiving Messages from Azure Service Bus

Use ServiceBusProcessorClient to process messages asynchronously.

Code Example

Practical Examples

Example 1: Sending Messages

Send a JSON payload to a Service Bus queue through an API endpoint and validate successful communication.

Request

Output

Example 2: Processing Received Messages

Set up a consumer that logs received messages for real-time monitoring.

Output

Conclusion

Integrating Azure Service Bus with Spring Boot simplifies message-based communication. By configuring the ServiceBusSenderClient for sending messages and ServiceBusProcessorClient for receiving them, you can build robust applications with scalable messaging solutions. Utilize these examples and practices to efficiently handle Service Bus queues and topics in your Spring Boot projects.
