一、安裝ActiveMQ
具體的安裝步驟,請參考我的另一篇博文:
http://blog.csdn.net/liuchuanhong1/article/details/52057711
二、新建spring boot工程,並加入JMS(ActiveMQ)依賴
三、工程結構
pom依賴如下:
- <?xml version="1.0" encoding="UTF-8"?>

- </dependency>
- <dependency>
- <groupId>org.springframework.boot</groupId>
- <artifactId>spring-boot-starter-test</artifactId>

- ## URL of the ActiveMQ broker. Auto-generated by default. For instance `tcp://localhost:61616`
- # failover:(tcp://localhost:61616,tcp://localhost:61617)
- # tcp://localhost:61616
- spring.activemq.broker-url=tcp://localhost:61616
- spring.activemq.in-memory=true
- spring.activemq.pool.enabled=false //如果此處設置爲true,需要加如下的依賴包,否則會自動配置失敗,報JmsMessagingTemplate注入失敗
- <dependency>
- <groupId>org.apache.activemq</groupId>
- <artifactId>activemq-pool</artifactId>
- <!-- <version>5.7.0</version> -->
- </dependency>
五、消息生產者
- package com.chhliu.springboot.jms;
- 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 // 也可以注入JmsTemplate,JmsMessagingTemplate對JmsTemplate進行了封裝
- private JmsMessagingTemplate jmsTemplate;
- // 發送消息,destination是發送到的隊列,message是待發送的消息
- public void sendMessage(Destination destination, final String message){
- jmsTemplate.convertAndSend(destination, message);
- }
- }
- package com.chhliu.springboot.jms;
- import org.springframework.jms.annotation.JmsListener;
- import org.springframework.stereotype.Component;
- @Component
- public class Consumer {
- // 使用JmsListener配置消費者監聽的隊列,其中text是接收到的消息
- @JmsListener(destination = "mytest.queue")
- public void receiveQueue(String text) {
- System.out.println("Consumer收到的報文爲:"+text);
- }
- }
七、測試
- package com.chhliu.springboot.jms;
- import javax.jms.Destination;
- import org.apache.activemq.command.ActiveMQQueue;
- import org.junit.Test;
- import org.junit.runner.RunWith;
- import org.springframework.beans.factory.annotation.Autowired;
- import org.springframework.boot.test.context.SpringBootTest;
- import org.springframework.test.context.junit4.SpringRunner;
- @RunWith(SpringRunner.class)
- @SpringBootTest
- public class SpringbootJmsApplicationTests {
- @Autowired
- private Producer producer;
- @Test
- public void contextLoads() throws InterruptedException {
- Destination destination = new ActiveMQQueue("mytest.queue");
- for(int i=0; i<100; i++){
- producer.sendMessage(destination, "myname is chhliu!!!");
- }
- }
- }
- Consumer2收到的報文爲:myname is chhliu!!!
- Consumer收到的報文爲:myname is chhliu!!!
- Consumer2收到的報文爲:myname is chhliu!!!
- Consumer收到的報文爲:myname is chhliu!!!
- Consumer2收到的報文爲:myname is chhliu!!!
- Consumer收到的報文爲:myname is chhliu!!!
- Consumer2收到的報文爲:myname is chhliu!!!
- Consumer收到的報文爲:myname is chhliu!!!
- Consumer2收到的報文爲:myname is chhliu!!!
- Consumer收到的報文爲:myname is chhliu!!!
- Consumer2收到的報文爲:myname is chhliu!!!
- Consumer收到的報文爲:myname is chhliu!!!
- Consumer2收到的報文爲:myname is chhliu!!!
經過上面的幾個步驟,spring boot和Jms就基本上整合完成了,是不是使用起來很方便了!
八、實現雙向隊列
1、下面首先來對Consumer2這個消費者來進行下改造,代碼如下:
- package com.chhliu.springboot.jms;
- import org.springframework.jms.annotation.JmsListener;
- import org.springframework.messaging.handler.annotation.SendTo;
- import org.springframework.stereotype.Component;
- @Component
- public class Consumer2 {
- @JmsListener(destination = "mytest.queue")
- @SendTo("out.queue")
- public String receiveQueue(String text) {
- System.out.println("Consumer2收到的報文爲:"+text);
- return "return message"+text;
- }
- }
進入Browse界面觀看:
最後看下收到的具體信息:
我們發現,該隊列中的消息,就是我們返回的值!
九、對Producer進行改造
通過上面的示例,我們現在對Producer進行改造,使其既能生產報文,又能消費隊列中的報文,代碼如下:
- package com.chhliu.springboot.jms;
- import javax.jms.Destination;
- import org.springframework.beans.factory.annotation.Autowired;
- import org.springframework.jms.annotation.JmsListener;
- 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);
- }
- @JmsListener(destination="out.queue")
- public void consumerMessage(String text){
- System.out.println("從out.queue隊列收到的回覆報文爲:"+text);
- }
- }
- 從out.queue隊列收到的回覆報文爲:return messagemyname is chhliu!!!
- Consumer收到的報文爲:myname is chhliu!!!
- Consumer2收到的報文爲:myname is chhliu!!!
- 從out.queue隊列收到的回覆報文爲:return messagemyname is chhliu!!!
- Consumer收到的報文爲:myname is chhliu!!!
- Consumer2收到的報文爲:myname is chhliu!!!
- 從out.queue隊列收到的回覆報文爲:return messagemyname is chhliu!!!
- Consumer收到的報文爲:myname is chhliu!!!
- Consumer2收到的報文爲:myname is chhliu!!!
- 從out.queue隊列收到的回覆報文爲:return messagemyname is chhliu!!!
