springboot 與activemq通訊

1、配置:

#==================activemq Config Start==================
spring.activemq.broker-url=tcp://localhost:61616
spring.activemq.in-memory=true
spring.activemq.pool.enabled=true
#==================activemq Config End  ==================

2、依賴:

		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-activemq</artifactId>
		</dependency>
		
		<dependency>
			<groupId>org.apache.activemq</groupId>
			<artifactId>activemq-pool</artifactId>
		</dependency>

3、消費者:

import org.springframework.jms.annotation.JmsListener;
import org.springframework.stereotype.Component;
 
@Component
public class Consumer {

	@JmsListener(destination = "mytest.queue")
	public void receiveQueue(String text) {
		System.out.println("Consumer收到的報文為:"+text);
	}
}

4、生產者:

import javax.jms.Destination;
 
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.core.JmsMessagingTemplate;
import org.springframework.stereotype.Service;
 
@Service("producer")
public class Producer {
	
	@Autowired 
	private JmsMessagingTemplate jmsTemplate;
	
	public void sendMessage(Destination destination, final String message){
		jmsTemplate.convertAndSend(destination, message);
	}
}

5、觸發訊息生產:

import javax.jms.Destination;

import org.apache.activemq.command.ActiveMQQueue;
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.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import com.example.activemq.service.Producer;

@RestController
@SpringBootApplication
public class DemoApplication implements CommandLineRunner {
	
	@Autowired
	private Producer producer;

	public static void main(String[] args) {
		SpringApplication.run(DemoApplication.class, args);
	}

	@RequestMapping("/")
	public String hello() {
		return "Hello world!";
	}

	@Override
	public void run(String... arg0) throws Exception {
		Destination destination = new ActiveMQQueue("mytest.queue");
		
		for(int i=0; i<100; i++){
			producer.sendMessage(destination, "myname is chhliu!!!");
		}
	}
}
