Spring Boot ActiveMQ如何设置访问密码

Apache ActiveMQ是Apache出品，是最流行的，能力很强的开源消息总线。默认情况下，程序连接ActiveMQ是不需要密码的，为了安装起见，需要设置密码，提高安全性。本文分享如何设置访问ActiveMQ的账号密码。

小编使用的ActiveMQ版本是apache-activemq-5.15.13。

一、设置控制台管理密码

ActiveMQ使用的是jetty服务器，找到 ActiveMQ安装目录下的confjetty.xml文件：

<bean 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的属性默认为'true'，登录管理界面时需要输入账户和密码；如果是“false”，需要改为'true'。

修改管理界面登录时的用户名和密码，在conf/jetty-realm.properties文件中添加用户

配置信息按顺序解释，分别是：用户名、密码、角色名

二、消息生产者和消费者密码认证

在confactivemq.xml中broker 标签最后添加生产者和消费者密码认证信息：

<!-- destroy the spring context on shutdown to stop jetty --> <shutdownHooks> <bean xmlns='http://www.springframework.org/schema/beans' /> </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，见如下步骤。

设置用户名密码，文件在confcredentials.properties

三、Java端配置用户名密码

验证代码是在《【Spring Boot】ActiveMQ 发布/订阅消息模式介绍》的基础上做重构，除了新增类ActiveMQConfig之外，修改部分均用红色字体标注。配置application.properties连接信息：

## URL of the ActiveMQ broker. Auto-generated by default. For instance `tcp://localhost:61616`# failover:(tcp://localhost:61616,tcp://localhost:61617)# tcp://localhost:61616spring.activemq.broker-url=tcp://localhost:61616spring.activemq.in-memory=truespring.activemq.pool.enabled=false#默认值false，表示point to point（点到点）模式，true时代表发布订阅模式，需要手动开启spring.jms.pub-sub-domain=truespring.activemq.user=wienerspring.activemq.password=wiener1237

在项目中配置 ActiveMQ连接属性，新增ActiveMQConfig类：

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*/@Configurationpublic 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); } /** * 设置点对点模式，和下面的发布订阅模式二选一即可 * @param connectionFactory * @return */ @Bean public JmsListenerContainerFactory<?> jmsListenerContainerQueue(ActiveMQConnectionFactory connectionFactory){ DefaultJmsListenerContainerFactory bean = new DefaultJmsListenerContainerFactory(); bean.setConnectionFactory(connectionFactory); return bean; } @Bean public JmsListenerContainerFactory<?> jmsListenerContainerTopic(ActiveMQConnectionFactory connectionFactory){ //设置为发布订阅模式, 默认情况下使用生产消费者方式 DefaultJmsListenerContainerFactory bean = new DefaultJmsListenerContainerFactory(); bean.setPubSubDomain(true); bean.setConnectionFactory(connectionFactory); return bean; }}

bean.setPubSubDomain(true)配置会覆盖properties文件中spring.jms.pub-sub-domain的属性值，故可以在properties不设置spring.jms.pub-sub-domain属性。另外，这种配置方式可以在系统中同时使用点对点和发布/订阅两种消息模式。修改订阅者：

import org.slf4j.Logger;import org.slf4j.LoggerFactory;import org.springframework.jms.annotation.JmsListener;import org.springframework.stereotype.Component;import javax.jms.JMSException;/*** 消费者*/@Componentpublic class Subscriber1 { private static Logger logger = LoggerFactory.getLogger(Subscriber1.class); /** * 订阅 topicListener1，仅仅加入containerFactory即可 * * @param text * @throws JMSException */ @JmsListener(destination = 'topicListener1', containerFactory = 'jmsListenerContainerTopic') public void subscriber(String text) { logger.info('Subscriber1 收到的报文：{}', text); }}

containerFactory 的值 'jmsListenerContainerTopic' 会自动匹配到ActiveMQConfig中的函数JmsListenerContainerFactory<?> jmsListenerContainerTopic(ActiveMQConnectionFactory connectionFactory)。 Subscriber2同样修改即可，代码省略。如果containerFactory 的值设置为jmsListenerContainerQueue，则开启了点到点消息模式。

测试函数还可以使用topicTest()。下面提供一个新的测试途径——在controller中测试。新增方法

@Autowiredprivate Publisher publisher;@GetMapping('/sendTopicMsg')public String sendTopicMsg(String msg) { // 指定消息发送的目的地及内容 Destination destination = new ActiveMQTopic('topicListener2'); for (int i = 0; i < 8; i++) { publisher.publish(destination, msg + i); } return msg + ' 发送完毕';}

执行结果省略。
