推荐答案

您需要通过设置authorizationPlugin来限制目标的创建:

you need to limit destinations creation by setting an authorizationPlugin :

只有具有管理员角色的用户可以发送和阅读消息以及创建目的地

only users with admins role can send and read messages and create destinations

只有具有生产者角色的用户可以发送消息

only users with producers role can send messages

只有具有消费者角色的用户可以阅读消息

only users with consumers role can read messages

添加到activemq.xml:

    <plugins>
        <jaasAuthenticationPlugin configuration="activemq"/>

       <authorizationPlugin>
           <map>
             <authorizationMap>
               <authorizationEntries>            
                 <authorizationEntry queue="test" read="consumers" write="producers" admin="admins" />
                 <authorizationEntry topic="ActiveMQ.Advisory.>" read="all" write="all" admin="all"/>
                 <authorizationEntry queue="ActiveMQ.>.>" read="admins" write="admins" admin="admins"/>
               </authorizationEntries>
               <tempDestinationAuthorizationEntry>
                 <tempDestinationAuthorizationEntry read="admins" write="admins" admin="admins"/>
               </tempDestinationAuthorizationEntry>
            </authorizationMap>
          </map>
       </authorizationPlugin>
    </plugins>

添加到login.config:

activemq {
    org.apache.activemq.jaas.PropertiesLoginModule required
        org.apache.activemq.jaas.properties.user="users.properties"
        org.apache.activemq.jaas.properties.group="groups.properties"
        reload=true;
};

添加到users.properties:

q_consumers=q_consumers_pwd
q_producers=q_producers_pwd
admin=admin

添加到groups.properties:

admins=admin
consumers=q_consumers
producers=q_producers
all=q_consumers,q_producers,admin

创建连接时，您必须通过用户& pwd:

javax.jms.ConnectionFactory.createConnection(String userName, String password);
