File paths

In this document, all file paths are valid for Linux, UNIX, and similar operating systems (for example, /home/andrea). On Microsoft Windows, you must use the equivalent Windows paths (for example, C:\Users\andrea).

Variable text

This document contains code blocks with variables that you must replace with values specific to your environment. Variable text is enclosed in arrow braces and styled as italic monospace. For example, in the following command, replace <project-dir> with the value for your environment:

$ cd <project-dir>

Chapter 2. Installation

This chapter guides you through the steps to install AMQ Spring Boot Starter in your environment.

2.1. Prerequisites

  • You must have a subscription to access AMQ release files and repositories.
  • To build programs with AMQ Spring Boot Starter, you must install Apache Maven.
  • To use AMQ Spring Boot Starter, you must install Java.

2.2. Using the Red Hat Maven repository

Configure your Maven environment to download the client library from the Red Hat Maven repository.


  1. Add the Red Hat repository to your Maven settings or POM file. For example configuration files, see Section B.1, “Using the online repository”.

  2. Add the library dependency to your POM file.


The client is now available in your Maven project.

2.3. Installing a local Maven repository

As an alternative to the online repository, AMQ Spring Boot Starter can be installed to your local filesystem as a file-based Maven repository.


  1. Use your subscription to download the AMQ Clients 2.7.0 Spring Boot Starter Maven repository .zip file.
  2. Extract the file contents into a directory of your choosing.

    On Linux or UNIX, use the unzip command to extract the file contents.

    $ unzip

    On Windows, right-click the .zip file and select Extract All.

  3. Configure Maven to use the repository in the maven-repository directory inside the extracted install directory. For more information, see Section B.2, “Using a local repository”.

Chapter 3. Getting started

This chapter guides you through the steps to set up your environment and run a simple messaging program.

3.1. Prerequisites

3.2. Running Hello World

The Hello World example creates a connection to the broker, sends a message containing a greeting to the example queue, and receives it back. On success, it prints the received message to the console.

Example: Sending and receiving "Hello World!" -

package net.example;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.jms.annotation.EnableJms;
import org.springframework.jms.annotation.JmsListener;
import org.springframework.jms.core.JmsTemplate;

public class HelloWorld implements CommandLineRunner {
    private JmsTemplate jmsTemplate;

    public static void main(String[] args) {, args);

    public void run(String... strings) throws Exception {
        sendMessage("Hello World!");

    public void sendMessage(String text) {
        System.out.println(String.format("Sending '%s'", text));
        this.jmsTemplate.convertAndSend("example", text);

    @JmsListener(destination = "example")
    public void receiveMessage(String text) {
        System.out.println(String.format("Received '%s'", text));

Running the example

To compile and run the example program, use the following procedure:


  1. Create a new project directory. This is referred to as <project-dir> in the steps that follow.
  2. Copy the example listing to the following location:

  3. Use a text editor to create a new <project-dir>/pom.xml file. Add the following XML to it:

  4. Change to the project directory and use the mvn command to compile the program.

    $ mvn clean package
  5. Use the java command to run the program.

    $ java -jar target/example-1.0.0-SNAPSHOT.jar

    Running the Hello World example results in the following console output:

    $ java -jar target/example-1.0.0-SNAPSHOT.jar
      .   ____          _            __ _ _
     /\\ / ___'_ __ _ _(_)_ __  __ _ \ \ \ \

     \\/  ___)| |_)| | | | | || (_| |  ) ) ) )
      '  |____| .__|_| |_|_| |_\__, | / / / /
     :: Spring Boot ::        (v2.0.5.RELEASE)

    Sending 'Hello World!'
    Received 'Hello World!'

3.3. Additional examples

More example programs are available from the AMQP 1.0 JMS Spring Boot project and the Spring project.

Chapter 4. Configuration

The following options can be used in an application-properties file to configure your Spring Boot application.

4.1. Connection options

These options determine how AMQ Spring Boot Starter establishes connections to remote AMQP peers. The starter uses AMQ JMS to communicate over the network. For more information, see Using the AMQ JMS Client.


The connection URI that the AMQ JMS client uses to establish new connections.

Connection URI format


For more information, see Connection URIs in Using the AMQ JMS Client.

The username used to authenticate the connection.
The password used to authenticate the connection.
The client ID applied to the connection.
If enabled, calls to receive with a timeout argument check the consumer’s local message buffer only. Otherwise, the remote peer is checked as well to ensure there are no messages available. It is disabled by default.
If enabled, calls to receiveNoWait check the consumer’s local message buffer only. Otherwise, the remote peer is checked as well to ensure there are no messages available. It is disabled by default.

4.2. Pooling options

These options determine how AMQ Spring Boot Starter caches JMS connections and sessions. The starter uses AMQ JMS Pool for its pooling. For more information, see Using the AMQ JMS Pool Library.

Controls whether pooling is enabled. It is disabled by default.
The maximum number of connections for a single pool. The default is 1.

The maximum number of sessions for each connection. The default is 500. A negative value removes any limit.

If the limit is exceeded, createSession() either blocks or throws an exception, depending on configuration.


If enabled, calls to createSession() block until a session becomes available in the pool. It is enabled by default.

If disabled, calls to createSession() throw an IllegalStateException if no session is available.

The time in milliseconds before a blocked call to createSession() throws an IllegalStateException. The default is -1, meaning the call blocks forever.
The time in milliseconds before a connection not currently on loan can be evicted from the pool. The default is 30 seconds. A value of 0 disables the timeout.
The time in milliseconds between periodic checks for expired connections. The default is 0, meaning the check is disabled.

If enabled, use a single anonymous JMS MessageProducer for all calls to createProducer(). It is enabled by default.

In rare cases, this behavior is undesirable. If disabled, every call to createProducer() results in a new MessageProducer instance.

When not using anonymous producers, the JMS Session can be configured to cache a certain number of MessageProducer objects with explicit destinations. As new producers are created that do not match the cached producers, the oldest entry in the cache is evicted.

If enabled, use the JMSContext classes of the underlying JMS provider. It is disabled by default.

In normal operation, the pool uses its own generic JMSContext implementation to wrap connections from the pool instead of using the provider implementation. The generic implementation might have limitations the provider implementation does not. However, when enabled, connections from the JMSContext API are not managed by the pool.

Appendix B. Using Red Hat Maven repositories

This section describes how to use Red Hat-provided Maven repositories in your software.

B.1. Using the online repository

Red Hat maintains a central Maven repository for use with your Maven-based projects. For more information, see the repository welcome page.

There are two ways to configure Maven to use the Red Hat repository:

Adding the repository to your Maven settings

This method of configuration applies to all Maven projects owned by your user, as long as your POM file does not override the repository configuration and the included profile is enabled.


  1. Locate the Maven settings.xml file. It is usually inside the .m2 directory in the user home directory. If the file does not exist, use a text editor to create it.

    On Linux or UNIX:


    On Windows:

  2. Add a new profile containing the Red Hat repository to the profiles element of the settings.xml file, as in the following example:

    Example: A Maven settings.xml file containing the Red Hat repository


For more information about Maven configuration, see the Maven settings reference.

Adding the repository to your POM file

To configure a repository directly in your project, add a new entry to the repositories element of your POM file, as in the following example:

Example: A Maven pom.xml file containing the Red Hat repository




For more information about POM file configuration, see the Maven POM reference.

B.2. Using a local repository

Red Hat provides file-based Maven repositories for some of its components. These are delivered as downloadable archives that you can extract to your local filesystem.

To configure Maven to use a locally extracted repository, apply the following XML in your Maven settings or POM file:


${repository-url} must be a file URL containing the local filesystem path of the extracted repository.

Appendix C. Using AMQ Broker with the examples

The AMQ Spring Boot Starter examples require a running message broker with a queue named example. Use the procedures below to install and start the broker and define the queue.

C.1. Installing the broker

Follow the instructions in Getting Started with AMQ Broker to install the broker and create a broker instance. Enable anonymous access.

The following procedures refer to the location of the broker instance as <broker-instance-dir>.

C.2. Starting the broker


  1. Use the artemis run command to start the broker.

    $ <broker-instance-dir>/bin/artemis run
  2. Check the console output for any critical errors logged during startup. The broker logs Server is now live when it is ready.

    $ example-broker/bin/artemis run
               __  __  ____    ____            _
         /\   |  \/  |/ __ \  |  _ \          | |
        /  \  | \  / | |  | | | |_) |_ __ ___ | | _____ _ __
       / /\ \ | |\/| | |  | | |  _ <| '__/ _ \| |/ / _ \ '__|
      / ____ \| |  | | |__| | | |_) | | | (_) |   <  __/ |
     /_/    \_\_|  |_|\___\_\ |____/|_|  \___/|_|\_\___|_|
     Red Hat AMQ <version>
    2020-06-03 12:12:11,807 INFO  [org.apache.activemq.artemis.integration.bootstrap] AMQ101000: Starting ActiveMQ Artemis Server
    2020-06-03 12:12:12,336 INFO  [org.apache.activemq.artemis.core.server] AMQ221007: Server is now live

C.3. Creating a queue

In a new terminal, use the artemis queue command to create a queue named example.

$ <broker-instance-dir>/bin/artemis queue create --name example --address example --auto-create-address --anycast

You are prompted to answer a series of yes or no questions. Answer N for no to all of them.

Once the queue is created, the broker is ready for use with the example programs.

C.4. Stopping the broker

When you are done running the examples, use the artemis stop command to stop the broker.

$ <broker-instance-dir>/bin/artemis stop
