一. 安裝ActiveMQhtml
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,下載連接以下:http://activemq.apache.org/download.html,解壓後的目錄結構以下:java
bin目錄結構以下:spring
若是咱們是32位的機器,就雙擊win32目錄下的activemq.bat,若是是64位機器,則雙擊win64目錄下的activemq.bat,運行結果以下:apache
啓動成功!成功以後在瀏覽器輸入http://127.0.0.1:8161/地址,能夠看到ActiveMQ的管理頁面,用戶名和密碼默認都是admin,以下:瀏覽器
2、新建spring boot工程,並加入JMS(ActiveMQ)依賴springboot
3、工程結構app
pom依賴以下:maven
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>
4、修改application.properties配置文件tcp
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
5、消息生產者spring-boot
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 // 也能夠注入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 }
6、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收到的報文爲:"+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,原理相似於使用SessionAwareMessageListener以及MessageListenerAdapter來實現消息驅動POJO
7、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 }
測試結果以下:
1 Consumer2收到的報文爲:myname is chhliu!!! 2 Consumer收到的報文爲:myname is chhliu!!! 3 Consumer2收到的報文爲:myname is chhliu!!! 4 Consumer收到的報文爲:myname is chhliu!!! 5 Consumer2收到的報文爲:myname is chhliu!!! 6 Consumer收到的報文爲:myname is chhliu!!! 7 Consumer2收到的報文爲:myname is chhliu!!! 8 Consumer收到的報文爲:myname is chhliu!!! 9 Consumer2收到的報文爲:myname is chhliu!!! 10 Consumer收到的報文爲:myname is chhliu!!! 11 Consumer2收到的報文爲:myname is chhliu!!! 12 Consumer收到的報文爲:myname is chhliu!!! 13 Consumer2收到的報文爲:myname is chhliu!!!
通過上面的幾個步驟,spring boot和Jms就基本上整合完成了,是否是使用起來很方便了!
8、實現雙向隊列
一、下面首先來對Consumer2這個消費者來進行下改造,代碼以下:
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收到的報文爲:"+text); 14 return "return message"+text; 15 } 16 }
從上面的代碼能夠看出,咱們在receiveQueue方法上面多加了一個註解@SendTo("out.queue"),該註解的意思是將return回的值,再發送到"out.queue"隊列中,該隊列中的消息,就是咱們返回的值!
9、對Producer進行改造
經過上面的示例,咱們如今對Producer進行改造,使其既能生產報文,又能消費隊列中的報文,代碼以下:
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隊列收到的回覆報文爲:"+text); 22 } 23 }
測試結果以下:
1 從out.queue隊列收到的回覆報文爲:return messagemyname is chhliu!!! 2 Consumer收到的報文爲:myname is chhliu!!! 3 Consumer2收到的報文爲:myname is chhliu!!! 4 從out.queue隊列收到的回覆報文爲:return messagemyname is chhliu!!! 5 Consumer收到的報文爲:myname is chhliu!!! 6 Consumer2收到的報文爲:myname is chhliu!!! 7 從out.queue隊列收到的回覆報文爲:return messagemyname is chhliu!!! 8 Consumer收到的報文爲:myname is chhliu!!! 9 Consumer2收到的報文爲:myname is chhliu!!! 10 從out.queue隊列收到的回覆報文爲:return messagemyname is chhliu!!!
