1.springboot+ActiveMQ | 易学教程

1.项目结构如下

pom.xml文件如下

 1  <dependencies>
 2     <dependency>
 3       <groupId>junit</groupId>
 4       <artifactId>junit</artifactId>
 5       <version>4.12</version>
 6     </dependency>
 7     <dependency>
 8       <groupId>org.springframework.boot</groupId>
 9       <artifactId>spring-boot-starter-activemq</artifactId>
10     </dependency>
11 
12     <!--消息队列连接池-->
13     <!--<dependency>-->
14       <!--<groupId>org.apache.activemq</groupId>-->
15       <!--<artifactId>activemq-pool</artifactId>-->
16       <!--<version>5.15.0</version>-->
17     <!--</dependency>-->
18   </dependencies>

pom.xml

2.创建消息提供者

pom.xml文件如下

 1  <dependencies>
 2     <dependency>
 3       <groupId>junit</groupId>
 4       <artifactId>junit</artifactId>
 5       <version>4.12</version>
 6     </dependency>
 7     <dependency>
 8       <groupId>org.springframework.boot</groupId>
 9       <artifactId>spring-boot-starter-activemq</artifactId>
10     </dependency>
11 
12     <!--消息队列连接池-->
13     <!--<dependency>-->
14       <!--<groupId>org.apache.activemq</groupId>-->
15       <!--<artifactId>activemq-pool</artifactId>-->
16       <!--<version>5.15.0</version>-->
17     <!--</dependency>-->
18   </dependencies>

pom.xml

2.1 创建属性文件如下：

 1 server.port=8080
 2 server.servlet.context-path=/pro
 3 spring.activemq.user=admin
 4 spring.activemq.password=admin
 5 #集群配置
 6 #spring.activemq.broker-url=failover:(tcp://localhost:61616,tcp://localhost:61617)
 7 #整合jms测试，安装在别的机器，防火墙和端口号记得开放
 8 spring.activemq.broker-url=tcp://192.168.117.152:61617
 9 queueName=publish.queue
10 topicName=publish.topic
11 
12 
13 
14 #ActiveMQ是消息队列技术，为解决高并发问题而生
15 #ActiveMQ生产者消费者模型（生产者和消费者可以跨平台、跨系统）
16 #ActiveMQ支持如下两种消息传输方式
17 #点对点模式，生产者生产了一个消息，只能由一个消费者进行消费
18 #发布/订阅模式，生产者生产了一个消息，可以由多个消费者进行消费

application.properties

2.2 定义消息队列类ActiveMQConfig.java
