一、设置后台管理密码
a、ActiveMQ使用的是jetty服务器，找到D:\div\apache-activemq-5.11.1\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：低版本的authenticate的属性默认为"false"，需要改为"true"，高版本的已经默认为true
b、修改控制台的登录用户名密码conf/jetty-realm.properties文件中

二、消息生产者和消费者密码认证
a、D:\div\apache-activemq-5.11.1\conf\activemq.xml添加生产者和消费者密码认证信息：
b、设置用户名密码，文件在D:\div\apache-activemq-5.11.1\conf\credentials.properties

# Defines credentials that will be used by components (like web console) to access the broker
activemq.username=ljq
activemq.password=ljq
guest.password=password
三、在Java生产者和消费者端设置用户名密码才能连接
ConnectionFactory connectionFactory = new ActiveMQConnectionFactory("ljq", "ljq", "failover:(tcp://localhost:61616)?Randomize=false");
