spring-boot学习：十九、spring-boot集成activemq

一、安装activemq（windows）

下载后解压到指定目录

http://activemq.apache.org/components/classic/download/

配置文件D:\software\apache-activemq-5.15.9\conf
1）jetty.xml
配置控制台地址和端口：

<bean id="jettyPort" class="org.apache.activemq.web.WebConsolePort" init-method="start">
		 <!-- the default port number for the web console -->
	<property name="host" value="0.0.0.0"/>
	<property name="port" value="8161"/>
</bean>

角色：

<bean id="securityConstraint" class="org.eclipse.jetty.util.security.Constraint">
	<property name="name" value="BASIC" />
	<property name="roles" value="user,admin" />
	<!-- set authenticate=false to disable login -->
	<property name="authenticate" value="true" />
</bean>

2）jetty-realm.properties
配置账号和角色

# username: password [,rolename ...]
admin: admin, admin
user: user, user

3）activemq.xml
配置连接地址/端口：默认61616

<transportConnectors>
	<!-- DOS protection, limit concurrent connections to 1000 and frame size to 100MB -->
	<transportConnector name="openwire" uri="tcp://0.0.0.0:61616?maximumConnections=1000&amp;wireFormat.maxFrameSize=104857600"/>
	<transportConnector name="amqp" uri="amqp://0.0.0.0:5672?maximumConnections=1000&amp;wireFormat.maxFrameSize=104857600"/>
	<transportConnector name="stomp" uri="stomp://0.0.0.0:61613?maximumConnections=1000&amp;wireFormat.maxFrameSize=104857600"/>
	<transportConnector name="mqtt" uri="mqtt://0.0.0.0:1883?maximumConnections=1000&amp;wireFormat.maxFrameSize=104857600"/>
	<transportConnector name="ws" uri="ws://0.0.0.0:61614?maximumConnections=1000&amp;wireFormat.maxFrameSize=104857600"/>
</transportConnectors>

<shutdownHooks>后面加入连接账号：

<plugins>   
	<simpleAuthenticationPlugin>   
		<users>   
			<authenticationUser username="${activemq.username}" password="${activemq.password}" groups="users,admins"/>   
		</users>   
	</simpleAuthenticationPlugin>   
</plugins>

4）credentials.properties
配置连接账号：

activemq.username=system
activemq.password=manager
guest.password=password

启动D:\software\apache-activemq-5.15.9\bin\win64\activemq.bat
登录控制台查看http://127.0.0.1:8161/admin/
使用账号admin/admin（参考jetty-realm.properties）

activemq支持两种消息
在这里插入图片描述
二、springboot集成activemq

1.pom.xml

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

<!-- 启用pool需要引入以下jar包 -->
<dependency>  
	 <groupId>org.apache.activemq</groupId>  
	 <artifactId>activemq-pool</artifactId>  
 </dependency>
 
 <dependency>
	 <groupId>org.messaginghub</groupId>
	 <artifactId>pooled-jms</artifactId>
 </dependency>

2.application.properties

# activemq （https://docs.spring.io/spring-boot/docs/2.1.5.RELEASE/reference/htmlsingle/#boot-features-activemq）
spring.activemq.broker-url=tcp://127.0.0.1:61616
spring.activemq.user=system
spring.activemq.password=manager
spring.activemq.pool.enabled=true
spring.activemq.pool.max-connections=500

3.Application.java

@EnableJms
public class Application extends SpringBootServletInitializer {

	// 当需要activemq支持topic消息，需要注册JmsListenerContainerFactory，且设置PubSubDomain为true，否则无法消费topic消息
	// 也可以在配置文件中加入spring.jms.pub-sub-domain=true，则只支持topic消息，不支持queue消息
	@Bean
	public DefaultJmsListenerContainerFactory jmsTopicListenerContainerFactory(
			ConnectionFactory connectionFactory) {
		DefaultJmsListenerContainerFactory factory = new DefaultJmsListenerContainerFactory();
		factory.setConnectionFactory(connectionFactory);
		factory.setPubSubDomain(true);
		return factory;
	}
}

4.消息生产者，直接使用JmsTemplate发送消息

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

import org.apache.activemq.command.ActiveMQQueue;
import org.apache.activemq.command.ActiveMQTopic;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jms.core.JmsTemplate;
import org.springframework.stereotype.Component;

@Component
public class ActivemqProducer {
	
	@Autowired
	private JmsTemplate jmsTemplate;
	
	public void sendMsg(Destination destination, String message) {
		jmsTemplate.convertAndSend(destination, message);
	}
	
	public void sendQueueMsg(Queue queue, String message) {
		sendMsg(queue, message);
	}
	
	public void sendQueueMsg(String queueName, String message) {
		sendMsg(new ActiveMQQueue(queueName), message);
	}
	
	public void sendTopicMsg(Topic queue, String message) {
		sendMsg(queue, message);
	}
	
	public void sendTopicMsg(String topicName, String message) {
		sendMsg(new ActiveMQTopic(topicName), message);
	}
}

5.消息消费者，分别创建了两个queue消费者和两个topic消费者，默认的containerFactory是queue消息，所以消费queue消息时可不配置containerFactory

import org.springframework.jms.annotation.JmsListener;
import org.springframework.stereotype.Component;

@Component
public class ActivemqConsumer {

	@JmsListener(destination = "spring-boot.queue")
    public void consumerQueueMessage(String message){
        System.out.println("收到spring-boot.queue报文："+message);
    }
	
	@JmsListener(destination = "spring-boot.queue")
    public void consumerQueueMessage2(String message){
        System.out.println("收到spring-boot.queue报文2："+message);
    }
	
	@JmsListener(destination = "spring-boot.topic", containerFactory = "jmsTopicListenerContainerFactory")
    public void consumerTopicMessage(String message){
        System.out.println("收到spring-boot.topic报文："+message);
    }
	
	@JmsListener(destination = "spring-boot.topic", containerFactory = "jmsTopicListenerContainerFactory")
    public void consumerTopicMessage2(String message){
        System.out.println("收到spring-boot.topic报文2："+message);
    }
	
}

6.测试（@OpenAPI和@OpenAPIMethod是自定义的接口注解，可直接使用

@RestController和@RequestMapping替换）
@Component
@OpenAPI
public class ApiTest {
	
	private static final Logger logger = LoggerFactory.getLogger(ApiTest.class);
	
	@Autowired
	private ActivemqProducer mqProducer;
	
	@OpenAPIMethod(methodName = "testActivemqSender")
    public Object testActivemqSender(final String msg) throws Exception {

		mqProducer.sendQueueMsg("spring-boot.queue", msg);
		
		mqProducer.sendTopicMsg("spring-boot.topic", msg);
		
		return null;
    }
}

访问：http://10.0.0.57:9001/api/testActivemqSender?msg=KevinTest

日志打印：
收到spring-boot.queue报文2：KevinTest
收到spring-boot.topic报文2：KevinTest
收到spring-boot.topic报文：KevinTest

7.查看控制台
queues：spring-boot.queue未消费的消息数为0，存在2个消费者，生产消息数为1，消费消息数为1
