配置类

package com.example.config;

import javax.jms.ConnectionFactory;
import javax.jms.Destination;

import org.apache.activemq.command.ActiveMQQueue;
import org.apache.activemq.command.ActiveMQTopic;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.jms.config.DefaultJmsListenerContainerFactory;
import org.springframework.jms.config.JmsListenerContainerFactory;

@Configuration
public class ActivemqConfig {

/**
* 自定义了4个Destination,两个queue,两个topic
*/
@Bean
public Destination queue1() {
return new ActiveMQQueue("queue-1");
}

@Bean
public Destination queue2() {
return new ActiveMQQueue("queue-2");
}

@Bean
public Destination topic1() {
return new ActiveMQTopic("topic-1");
}

@Bean
public Destination topic2() {
return new ActiveMQTopic("topic-2");
}

/**
* JmsListener注解默认只接收queue消息,如果要接收topic消息,需要设置containerFactory
*/
@Bean
public JmsListenerContainerFactory<?> topicListenerContainer(ConnectionFactory activeMQConnectionFactory) {
DefaultJmsListenerContainerFactory topicListenerContainer = new DefaultJmsListenerContainerFactory();
topicListenerContainer.setPubSubDomain(true);
topicListenerContainer.setConnectionFactory(activeMQConnectionFactory);
return topicListenerContainer;
}

}

controller

package com.example.controller;

import javax.annotation.Resource;
import javax.jms.Destination;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

/**
* 通过页面访问的方式生产消息
*/
@RestController
public class ProviderController {

@Autowired
private JmsTemplate jmsTemplate;

@Resource(name = "queue1")
private Destination queue1;

@Resource(name = "topic1")
private Destination topic1;

@GetMapping("/send/queue1")
public String send1() {
jmsTemplate.convertAndSend(queue1, "hello queue-1");
return "ok";
}

@GetMapping("/send/topic1")
public String send2() {
jmsTemplate.convertAndSend(topic1, "hello topic-1");
return "ok";
}

}

接收消息

package com.example.message;

import org.springframework.jms.annotation.JmsListener;
import org.springframework.stereotype.Component;

/**
* 接收处理消息
*/
@Component
public class MessageHandler {

@JmsListener(destination="queue-1")
public void recieve1(String message) {
System.out.println("###################" + message + "###################");
}

@JmsListener(destination="topic-1", containerFactory="topicListenerContainer")
public void recieve2(String message) {
System.out.println("###################" + message + "###################");
}

}

配置文件application.properties

spring.activemq.broker-url=tcp://192.168.32.128:61616

启动类

package com.example;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class ActivemqTestApplication {

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

访问http://localhost:8080/send/queue1或者http://localhost:8080/send/topic1,可以看到控制台的输出
