【Spring Boot】ActiveMQ 設置訪問密碼

       Apache ActiveMQ是Apache出品，是最流行的，能力很強的開源消息總線。默認情況下，程序連接ActiveMQ是不需要密碼的，為了安裝起見，需要設置密碼，提高安全性。本文分享如何設置訪問ActiveMQ的賬號密碼。 

     小編使用的ActiveMQ版本是apache-activemq-5.15.13。

一、設置控制台管理密碼

    ActiveMQ使用的是jetty服務器，找到 ActiveMQ安裝目錄下的\conf\jetty.xml文件：

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

    注意：authenticate的屬性默認為"true"，登錄管理界面時需要輸入賬戶和密碼；如果是“false”，需要改為"true"。

   修改管理界面登錄時的用戶名和密碼，在conf/jetty-realm.properties文件中添加用戶

     配置信息按順序解釋，分別是：用戶名、密碼、角色名

二、消息生產者和消費者密碼認證 

   在\conf\activemq.xml中broker 標簽最后添加生產者和消費者密碼認證信息：

        <!-- destroy the spring context on shutdown to stop jetty -->
        <shutdownHooks>
            <bean xmlns="http://www.springframework.org/schema/beans" class="org.apache.activemq.hooks.SpringContextHook" />
        </shutdownHooks>
        <!-- add plugins -->
        <plugins>
            <simpleAuthenticationPlugin>
                <users>
                    <authenticationUser username="${activemq.username}" password="${activemq.password}" groups="users,admins"/>
                </users>
            </simpleAuthenticationPlugin>
        </plugins>
    </broker>

    activemq.username和activemq.password的值在文件credentials.properties中配置，見如下步驟。 

   設置用戶名密碼，文件在\conf\credentials.properties

 三、Java端配置用戶名密碼

    驗證代碼是在《【Spring Boot】ActiveMQ 發布/訂閱消息模式介紹》的基礎上做重構，除了新增類ActiveMQConfig之外，修改部分均用紅色字體標注。配置application.properties連接信息：

## 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 #默認值false，表示point to point（點到點）模式，true時代表發布訂閱模式，需要手動開啟 spring.jms.pub-sub-domain=true spring.activemq.user=wiener spring.activemq.password=wiener1237

    在項目中配置 ActiveMQ連接屬性，新增ActiveMQConfig類：

import org.apache.activemq.ActiveMQConnectionFactory; import org.springframework.beans.factory.annotation.Value; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.jms.config.DefaultJmsListenerContainerFactory; import org.springframework.jms.config.JmsListenerContainerFactory; /** * 配置 ActiveMQ * * @author east7 * @date 2020/6/23 11:27 */ @Configuration public class ActiveMQConfig { @Value("${spring.activemq.user}") private String usrName; @Value("${spring.activemq.password}") private String password; @Value("${spring.activemq.broker-url}") private String brokerUrl; @Bean public ActiveMQConnectionFactory connectionFactory() { System.out.println("password =========== " + password); return new ActiveMQConnectionFactory(usrName, password, brokerUrl); } /** * 設置點對點模式，和下面的發布訂閱模式二選一即可 * @param connectionFactory * @return
     */ @Bean public JmsListenerContainerFactory<?> jmsListenerContainerQueue(ActiveMQConnectionFactory connectionFactory){ DefaultJmsListenerContainerFactory bean = new DefaultJmsListenerContainerFactory(); bean.setConnectionFactory(connectionFactory); return bean; } @Bean public JmsListenerContainerFactory<?> jmsListenerContainerTopic(ActiveMQConnectionFactory connectionFactory){ //設置為發布訂閱模式, 默認情況下使用生產消費者方式
        DefaultJmsListenerContainerFactory bean = new DefaultJmsListenerContainerFactory(); bean.setPubSubDomain(true); bean.setConnectionFactory(connectionFactory); return bean; } }

    bean.setPubSubDomain(true)配置會覆蓋properties文件中spring.jms.pub-sub-domain的屬性值，故可以在properties不設置spring.jms.pub-sub-domain屬性。另外，這種配置方式可以在系統中同時使用點對點和發布/訂閱兩種消息模式。修改訂閱者：

import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.jms.annotation.JmsListener; import org.springframework.stereotype.Component; import javax.jms.JMSException; /** * 消費者 */ @Component public class Subscriber1 { private static Logger logger = LoggerFactory.getLogger(Subscriber1.class); /** * 訂閱 topicListener1，僅僅加入containerFactory即可 * * @param text * @throws JMSException */ @JmsListener(destination = "topicListener1", containerFactory = "jmsListenerContainerTopic") public void subscriber(String text) { logger.info("Subscriber1 收到的報文：{}", text); } }

     containerFactory 的值 "jmsListenerContainerTopic" 會自動匹配到ActiveMQConfig中的函數JmsListenerContainerFactory<?> jmsListenerContainerTopic(ActiveMQConnectionFactory connectionFactory)。  Subscriber2同樣修改即可，代碼省略。如果containerFactory 的值設置為jmsListenerContainerQueue，則開啟了點到點消息模式。

     測試函數還可以使用topicTest()。下面提供一個新的測試途徑——在controller中測試。新增方法

@Autowired private Publisher publisher; @GetMapping("/sendTopicMsg") public String sendTopicMsg(String msg) { // 指定消息發送的目的地及內容
    Destination destination = new ActiveMQTopic("topicListener2"); for (int i = 0; i < 8; i++) { publisher.publish(destination, msg + i); } return msg + " 發送完畢"; }

    執行結果省略。
