This article introduces the relevant knowledge of "how to integrate Activemq in Springboot". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

1 Import the dependencies required for integration:

Org.springframework.boot spring-boot-starter-activemq

2 create an application.properties file

Spring.activemq.broker-url=tcp://127.0.0.1:61616spring.activemq.user=adminspring.activemq.password=adminserver.port=8080queue=myqueue

3. Custom profile QueueConfig reads the queue name of the configuration file and creates a Queue based on the queue name

Package com.example.demo;import javax.jms.Queue;import org.apache.activemq.ActiveMQConnectionFactory;import org.apache.activemq.command.ActiveMQQueue;import org.springframework.beans.factory.annotation.Value;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import org.springframework.jms.config.DefaultJmsListenerContainerFactory;import org.springframework.jms.core.JmsTemplate;@Configurationpublic class QueueConfig {@ Value ("${queue}") private String queue; @ Bean public Queue logQueue () {return new ActiveMQQueue (queue) }}

4. To create a producer, you can directly use the provided template JmsMessagingTemplate to send messages:

Package com.example.demo.producter;import javax.jms.Queue;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.jms.core.JmsMessagingTemplate;import org.springframework.stereotype.Component;import com.example.demo.SpringbootActivemqApplication;@Componentpublic class Producter {@ Autowired private JmsMessagingTemplate jmsMessagingTemplate; @ Autowired private Queue queue; private static Logger logger = LoggerFactory.getLogger (Producter .class) Public void send () {String str = "producer production data:" + System.currentTimeMillis (); jmsMessagingTemplate.convertAndSend (queue, str); logger.info ("producer data: {}", str);}}

5. Startup class:

Package com.example.demo;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.context.ApplicationListener;import org.springframework.context.event.ContextRefreshedEvent;import org.springframework.scheduling.annotation.EnableScheduling;import com.example.demo.producter.Producter;import com.example.demo.producter.consumer.Consumer;@SpringBootApplication@EnableSchedulingpublic class SpringbootActivemqApplication implements ApplicationListener {@ Autowired public Producter producter; @ Autowired public Consumer consumer Public static void main (String [] args) {SpringApplication.run (SpringbootActivemqApplication.class, args); / / onApplicationEvent method runs this method when starting springboot. You can choose the appropriate method to call the message according to the actual situation of the project} @ Override public void onApplicationEvent (ContextRefreshedEvent event) {producter.send ();}}

6. Start the project and output from the console:

7. It is easy to create consumers. You only need to listen to the queue:

Package com.example.demo.producter.consumer;import org.springframework.jms.annotation.JmsListener;import org.springframework.stereotype.Component;@Componentpublic class Consumer {@ JmsListener (destination = "${queue}") public void receive (String msg) {System.out.println ("listener receives msg:" + msg);}}

8. The final result:
