activemq学习——SpringBoot整合之生产者及定时投递消息（队列+主题）

导航页：https://blog.csdn.net/baokx/article/details/100745165

新建springboot工程，增加依赖：

    org.springframework.boot
    spring-boot-starter-activemq
    2.1.8.RELEASE

配置文件：

server:
  port: 7777
spring:
  activemq:
    broker-url: tcp://192.168.207.128:61616
    user: admin
    password: admin
  jms:
    pub-sub-domain: false #defalut queue  topic:true
my-destination: boot-activemq-queue #boot-activemq-topic

新建配置类：

package com.baokx.boot.activemq.producer.config;

import org.apache.activemq.command.ActiveMQQueue;
import org.apache.activemq.command.ActiveMQTopic;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.jms.annotation.EnableJms;
import org.springframework.stereotype.Component;

import javax.jms.Queue;
import javax.jms.Topic;

/**
 * @author kexiang.bao
 * @create 2019-09-18 20:17
 */
@Component
@EnableJms
public class ConfigBean {
    @Value("${my-destination}")
    private String myDestination;

    @Bean
    public Queue queue(){
        return new ActiveMQQueue(myDestination);
    }

    @Bean
    public Topic topic(){
        return new ActiveMQTopic(myDestination);
    }
}

新建生产者类：

package com.baokx.boot.activemq.producer;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.core.JmsMessagingTemplate;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;

import javax.jms.Destination;
import javax.jms.Queue;
import javax.jms.Topic;
import java.util.UUID;

/**
 * @author kexiang.bao
 * @create 2019-09-18 20:21
 */
@Component
public class QueueProducer {
    @Autowired
    private JmsMessagingTemplate jmsMessagingTemplate;

    @Autowired
    private Destination queue;

//    @Autowired
//    private Destination topic;

    public void produceMsg(){
        jmsMessagingTemplate.convertAndSend(queue, "boot-produce-msg:" + UUID.randomUUID().toString().substring(0,6));
//        jmsMessagingTemplate.convertAndSend(topic, "boot-produce-msg:" + UUID.randomUUID().toString().substring(0,6));
    }

    //每隔3秒定投
    @Scheduled(fixedDelay = 3000)
    public void produceMsgScheduled(){
        jmsMessagingTemplate.convertAndSend(queue, "boot-produce-msg:" + UUID.randomUUID().toString().substring(0,6));
//        jmsMessagingTemplate.convertAndSend(topic, "boot-produce-msg:" + UUID.randomUUID().toString().substring(0,6));
        System.out.println("produceMsgScheduled send ok...");
    }
}

主启动类：

package com.baokx.boot.activemq.producer;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableScheduling;

@SpringBootApplication
@EnableScheduling
public class ProducerApplication {

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

}

测试类：

package com.baokx.boot.activemq.producer;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.test.context.web.WebAppConfiguration;

import javax.annotation.Resource;

@SpringBootTest(classes = ProducerApplication.class)
@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
public class ProducerApplicationTests {

    @Resource
    private QueueProducer queueProducer;

    @Test
    public void testSend() throws Exception{
        queueProducer.produceMsg();
    }

}
