Introduction

ActiveMQ shovels are a powerful feature that allows you to move messages between different ActiveMQ brokers. This capability is particularly useful in scenarios where you need to integrate systems across various locations or consolidate message processing. In this guide, we will cover how to configure ActiveMQ shovels for moving messages between brokers in a Spring Boot application, ensuring efficient and reliable message transfer.

Steps to Configure ActiveMQ Shovels for Message Movement

1. Add Required Dependencies

Ensure that your pom.xml file includes the necessary dependencies for ActiveMQ and Spring Boot:

2. Broker Configuration

You need to configure each ActiveMQ broker that will be involved in the shovel setup. This involves defining the shovel parameters within the broker's XML configuration.

Example Broker Configuration (broker1.xml):

Example Broker Configuration (broker2.xml):

3. Configure Spring Boot Application

In your Spring Boot application, configure the application properties to connect to one of the brokers. The shovel will handle the message movement automatically.

Example application.properties:

4. Sending and Receiving Messages

You can create a message producer to send messages to the source queue, which will then be shovelled to the destination queue in the other broker.

Example Message Producer:

Example Message Consumer:

5. Running the Application

When you run your Spring Boot application and send a message to the source queue, it should automatically be moved to the destination queue on the other broker through the configured shovel.

6. Testing the Shovel Configuration

To test the shovel configuration, you can create a command-line runner or a REST endpoint to send messages to the source queue and observe their consumption from the destination queue.

Example Command-Line Runner:

Conclusion

Configuring ActiveMQ shovels for moving messages between brokers in a Spring Boot application is a straightforward process that enables efficient message transfer. By setting up the shovel in the broker configuration, you can easily route messages from one broker to another, facilitating communication across distributed systems. This setup is particularly useful for ensuring that messages are processed consistently and reliably, regardless of their originating location.
