一. 安裝ActiveMQ
到Apache官方網站下載最新的ActiveMQ的安裝包,並解壓到本地目錄下,下載鏈接如下:http://activemq.apache.org/download.html,解壓后的目錄結構如下:
bin目錄結構如下:

如果我們是32位的機器,就雙擊win32目錄下的activemq.bat,如果是64位機器,則雙擊win64目錄下的activemq.bat,運行結果如下:

啟動成功!成功之后在瀏覽器輸入http://127.0.0.1:8161/地址,可以看到ActiveMQ的管理頁面,用戶名和密碼默認都是admin,如下:

二、新建spring boot工程,並加入JMS(ActiveMQ)依賴
三、工程結構

pom依賴如下:
1 <?xml version="1.0" encoding="UTF-8"?> 2 <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 3 xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> 4 <modelVersion>4.0.0</modelVersion> 5 6 <groupId>com.chhliu.springboot.jms</groupId> 7 <artifactId>springboot-jms</artifactId> 8 <version>0.0.1-SNAPSHOT</version> 9 <packaging>jar</packaging> 10 11 <name>springboot-jms</name> 12 <description>Demo project for Spring Boot Jms</description> 13 14 <parent> 15 <groupId>org.springframework.boot</groupId> 16 <artifactId>spring-boot-starter-parent</artifactId> 17 <version>1.4.3.RELEASE</version> 18 <relativePath/> <!-- lookup parent from repository --> 19 </parent> 20 21 <properties> 22 <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> 23 <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> 24 <java.version>1.7</java.version> 25 </properties> 26 27 <dependencies> 28 <dependency> 29 <groupId>org.springframework.boot</groupId> 30 <artifactId>spring-boot-starter-activemq</artifactId> 31 </dependency> 32 33 <dependency> 34 <groupId>org.springframework.boot</groupId> 35 <artifactId>spring-boot-starter-test</artifactId> 36 <scope>test</scope> 37 </dependency> 38 </dependencies> 39 40 <build> 41 <plugins> 42 <plugin> 43 <groupId>org.springframework.boot</groupId> 44 <artifactId>spring-boot-maven-plugin</artifactId> 45 </plugin> 46 </plugins> 47 </build> 48 </project>
四、修改application.properties配置文件
1 ## URL of the ActiveMQ broker. Auto-generated by default. For instance `tcp://localhost:61616` 2 # failover:(tcp://localhost:61616,tcp://localhost:61617) 3 # tcp://localhost:61616 4 spring.activemq.broker-url=tcp://localhost:61616 5 spring.activemq.in-memory=true 6 spring.activemq.pool.enabled=false
五、消息生產者
1 package com.chhliu.springboot.jms;
2
3 import javax.jms.Destination;
4
5 import org.springframework.beans.factory.annotation.Autowired;
6 import org.springframework.jms.core.JmsMessagingTemplate;
7 import org.springframework.stereotype.Service;
8
9 @Service("producer")
10 public class Producer {
11 @Autowired // 也可以注入JmsTemplate,JmsMessagingTemplate對JmsTemplate進行了封裝
12 private JmsMessagingTemplate jmsTemplate;
13 // 發送消息,destination是發送到的隊列,message是待發送的消息
14 public void sendMessage(Destination destination, final String message){
15 jmsTemplate.convertAndSend(destination, message);
16 }
17 }
六、消息消費者
1 package com.chhliu.springboot.jms;
2
3 import org.springframework.jms.annotation.JmsListener;
4 import org.springframework.stereotype.Component;
5
6 @Component
7 public class Consumer {
8 // 使用JmsListener配置消費者監聽的隊列,其中text是接收到的消息
9 @JmsListener(destination = "mytest.queue")
10 public void receiveQueue(String text) {
11 System.out.println("Consumer收到的報文為:"+text);
12 }
13 }
消費者2的代碼同上,注意,消息消費者的類上必須加上@Component,或者是@Service,這樣的話,消息消費者類就會被委派給Listener類,原理類似於使用SessionAwareMessageListener以及MessageListenerAdapter來實現消息驅動POJO
七、測試
1 package com.chhliu.springboot.jms;
2
3 import javax.jms.Destination;
4
5 import org.apache.activemq.command.ActiveMQQueue;
6 import org.junit.Test;
7 import org.junit.runner.RunWith;
8 import org.springframework.beans.factory.annotation.Autowired;
9 import org.springframework.boot.test.context.SpringBootTest;
10 import org.springframework.test.context.junit4.SpringRunner;
11
12 @RunWith(SpringRunner.class)
13 @SpringBootTest
14 public class SpringbootJmsApplicationTests {
15
16 @Autowired
17 private Producer producer;
18
19 @Test
20 public void contextLoads() throws InterruptedException {
21 Destination destination = new ActiveMQQueue("mytest.queue");
22
23 for(int i=0; i<100; i++){
24 producer.sendMessage(destination, "myname is chhliu!!!");
25 }
26 }
27
28 }
測試結果如下:
1 Consumer2收到的報文為:myname is chhliu!!! 2 Consumer收到的報文為:myname is chhliu!!! 3 Consumer2收到的報文為:myname is chhliu!!! 4 Consumer收到的報文為:myname is chhliu!!! 5 Consumer2收到的報文為:myname is chhliu!!! 6 Consumer收到的報文為:myname is chhliu!!! 7 Consumer2收到的報文為:myname is chhliu!!! 8 Consumer收到的報文為:myname is chhliu!!! 9 Consumer2收到的報文為:myname is chhliu!!! 10 Consumer收到的報文為:myname is chhliu!!! 11 Consumer2收到的報文為:myname is chhliu!!! 12 Consumer收到的報文為:myname is chhliu!!! 13 Consumer2收到的報文為: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:
1 package com.chhliu.springboot.jms;
2
3 import org.springframework.jms.annotation.JmsListener;
4 import org.springframework.messaging.handler.annotation.SendTo;
5 import org.springframework.stereotype.Component;
6
7 @Component
8 public class Consumer2 {
9
10 @JmsListener(destination = "mytest.queue")
11 @SendTo("out.queue")
12 public String receiveQueue(String text) {
13 System.out.println("Consumer2收到的報文為:"+text);
14 return "return message"+text;
15 }
16 }
從上面的代碼可以看出,我們在receiveQueue方法上面多加了一個注解@SendTo("out.queue"),該注解的意思是將return回的值,再發送到"out.queue"隊列中,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:
1 package com.chhliu.springboot.jms;
2
3 import javax.jms.Destination;
4
5 import org.springframework.beans.factory.annotation.Autowired;
6 import org.springframework.jms.annotation.JmsListener;
7 import org.springframework.jms.core.JmsMessagingTemplate;
8 import org.springframework.stereotype.Service;
9
10 @Service("producer")
11 public class Producer {
12 @Autowired
13 private JmsMessagingTemplate jmsTemplate;
14
15 public void sendMessage(Destination destination, final String message){
16 jmsTemplate.convertAndSend(destination, message);
17 }
18
19 @JmsListener(destination="out.queue")
20 public void consumerMessage(String text){
21 System.out.println("從out.queue隊列收到的回復報文為:"+text);
22 }
23 }
測試結果如下:
1 從out.queue隊列收到的回復報文為:return messagemyname is chhliu!!! 2 Consumer收到的報文為:myname is chhliu!!! 3 Consumer2收到的報文為:myname is chhliu!!! 4 從out.queue隊列收到的回復報文為:return messagemyname is chhliu!!! 5 Consumer收到的報文為:myname is chhliu!!! 6 Consumer2收到的報文為:myname is chhliu!!! 7 從out.queue隊列收到的回復報文為:return messagemyname is chhliu!!! 8 Consumer收到的報文為:myname is chhliu!!! 9 Consumer2收到的報文為:myname is chhliu!!! 10 從out.queue隊列收到的回復報文為:return messagemyname is chhliu!!!
