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\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\conf\activemq.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" 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,见如下步骤。
设置用户名密码,文件在\conf\credentials.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:61616 spring.activemq.broker-url=tcp://localhost:61616 spring.activemq.in-memory=true spring.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=true spring.activemq.user=wiener spring.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 */ @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); } /** * 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 */ @Component public 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
@Autowired private 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。
