ActiveMQ下载默认不开启安全验证，级访问服务器不需要输入用户名、密码，如何开启安全验证：
1、ActiveMQ使用的是jetty服务器，服务器的安全开关配置在conf/jetty.xml配置文件中要开启安全验证只需修改authenticate的值为true，及修改如下代码 name="authenticate" 的value为true即可
<bean id="securityConstraint" class="org.eclipse.jetty.http.security.Constraint">
<property name="name" value="BASIC" />
<property name="roles" value="admin" />
<property name="authenticate" value="false" />
</bean>
2、登录用户名和密码保存在conf/jetty-realm.properties文件中,内容如下:

admin: admin, admin
如上所示，默认用户名为admin、密码为admin、拥有admin权限。如需修改用户名、密码、角色，对应修改上面的三个值即可
