How to send/publish message to ActiveMQ

step-1

create spring boot with following maven dependency
1-spring-boot-starter-activemq
2-jackson-databind

Example:

	<dependency>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-activemq</artifactId>
	</dependency>
   <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-databind</artifactId>
   </dependency>

step-2

create following bean and Inject JmsTemplate bean
1-ConnectionFactory

Example of beans:

	@Bean
	public ConnectionFactory connectionFactory() {
		//note active support 5(tcp,amqp,stomp,mqtt,ws) protocols to connect the broker
			/*Listening for connections at: tcp://localhost:61616?maximumConnections=1000&wireFormat.maxFrameSize=104857600
			Listening for connections at: amqp://localhost:5672?maximumConnections=1000&wireFormat.maxFrameSize=104857600
			Listening for connections at: stomp://localhost:61613?maximumConnections=1000&wireFormat.maxFrameSize=104857600
			Listening for connections at: mqtt://localhost:1883?maximumConnections=1000&wireFormat.maxFrameSize=104857600
			Listening for connections at ws://localhost:61614?maximumConnections=1000&wireFormat.maxFrameSize=104857600
	*/	
		// ActiveMQConnectionFactory is factory class for tcp protocol..each protocol have their own factory class.
		ActiveMQConnectionFactory factory  =  new ActiveMQConnectionFactory("tcp://localhost:61616");
		factory.setUserName("admin");
		factory.setPassword("admin");
		return factory;
	}

Injecting JmsTemplate bean

@Autowired
private JmsTemplate jmsTemplate;	

calling jsmTemplate method using CommadLineRunner

@Override
public void run(String... args) throws Exception {
	System.out.println("message sending started..");
	jmsTemplate.convertAndSend("myQueue", "This is first message from sender code.");
	System.out.println("message sending finished..");	
}
