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：
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：
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: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;
@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);
}
@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;
@Component
public class Subscriber1 {
private static Logger logger = LoggerFactory.getLogger(Subscriber1.class);
@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。
