一、认证
认证(Authentication):验证某个实体或者用户是否有权限访问受保护资源。
MQ提供两种插件用于权限认证:
(一)、Simple authentication plug-in:直接把相关的权限认证信息配置到XML文件中。
配置 conf/activemq.xml 的 broke元素添加插件:
<plugins> <simpleAuthenticationPlugin> <users> <authenticationUser username="admin" password="password" groups="admins,publishers,consumers"/> <authenticationUser username="publisher" password="password" groups="publishers,consumers"/> <authenticationUser username="consumer" password="password" groups="consumers"/> <authenticationUser username="guest" password="password" groups="guests"/> </users> </simpleAuthenticationPlugin> </plugins>
代码中的认证方式两种:
1、在创建Connection的时候认证
//用户认证 Connection conn = connFactory.createConnection("admin","password");
2、也可以在创建ConnectionFactory工厂的时候认证
ConnectionFactory connFactory = new ActiveMQConnectionFactory("admin","password",url);
(二)、JAAS authentication plug-in:实现了JAAS API,提供了一个更强大的和可定制的权限方案。
配置方式:
1、在conf目录中创建 login.config 文件 用户 配置 PropertiesLoginModule:
activemq-domain { org.apache.activemq.jaas.PropertiesLoginModule required debug=true org.apache.activemq.jaas.properties.user="users.properties" org.apache.activemq.jaas.properties.group="groups.properties"; };
2、在conf目录中创建users.properties 文件用户配置用户:
# 创建四个用户 admin=password publisher=password consumer=password guest=password
3、在conf目录中创建groups.properties 文件用户配置用户组:
#创建四个组并分配用户
admins=admin
publishers=admin,publisher
consumers=admin,publisher,consumer
guests=guest
4、将该配置插入到activemq.xml中:
<!-- JAAS authentication plug-in --> <plugins> <jaasAuthenticationPlugin configuration="activemq-domain" /> </plugins>
5、配置MQ的启动参数:
使用dos命令启动:
D:/tools/apache-activemq-5.6.0-bin/apache-activemq-5.6.0/bin/win64>activemq.bat -Djava.security.auth.login.config=D:/tools/apache-activemq-5.6.0-bin/apache-activemq-5.6.0/conf/login.config
6、在代码中的认证方式与Simple authentication plug-in 相同。
二、授权
基于认证的基础上,可以根据实际用户角色来授予相应的权限,如有些用户有队列写的权限,有些则只能读等等。
两种授权方式
(一)、目的地级别授权
JMS目的地的三种操作级别:
Read :读取目的地消息权限
Write:发送消息到目的地权限
Admin:管理目的地的权限
配置方式 conf/activemq.xml :
<plugins> <jaasAuthenticationPlugin configuration="activemq-domain" /> <authorizationPlugin> <map> <authorizationMap> <authorizationEntries> <authorizationEntry topic="topic.ch09" read="consumers" write="publishers" admin="publishers" /> </authorizationEntries> </authorizationMap> </map> </authorizationPlugin> </plugins>
(二)、消息级别授权
授权特定的消息。
开发步骤:
1、实现消息授权插件,需要实现MessageAuthorizationPolicy接口
public class AuthorizationPolicy implements MessageAuthorizationPolicy { private static final Log LOG = LogFactory. getLog(AuthorizationPolicy.class); public boolean isAllowedToConsume(ConnectionContext context, Message message) { LOG.info(context.getConnection().getRemoteAddress()); String remoteAddress = context.getConnection().getRemoteAddress(); if (remoteAddress.startsWith("/127.0.0.1")) { LOG.info("Permission to consume granted"); return true; } else { LOG.info("Permission to consume denied"); return false; } } }
2、把插件实现类打成JAR包,放入到activeMq 的 lib目录中
3、在activemq.xml中设置<messageAuthorizationPolicy>元素
<messageAuthorizationPolicy> <bean class="org.apache.activemq.book.ch6.AuthorizationPolicy" xmlns="http://www.springframework.org/schema/beans" /> </messageAuthorizationPolicy>
三、自定义安全插件
插件逻辑需要实现BrokerFilter类,并且通过BrokerPlugin实现类来安装,用于拦截,Broker级别的操作:
- 接入消费者和生产者
- 提交事务
- 添加和删除broker的连接
demo:基于IP地址,限制Broker连接。
package ch02.ptp; import java.util.List; import org.apache.activemq.broker.Broker; import org.apache.activemq.broker.BrokerFilter; import org.apache.activemq.broker.ConnectionContext; import org.apache.activemq.command.ConnectionInfo; public class IPAuthenticationBroker extends BrokerFilter { List<String> allowedIPAddresses; public IPAuthenticationBroker(Broker next, List<String>allowedIPAddresses) { super(next); this.allowedIPAddresses = allowedIPAddresses; } public void addConnection(ConnectionContext context, ConnectionInfo info) throws Exception { String remoteAddress = context.getConnection().getRemoteAddress(); if (!allowedIPAddresses.contains(remoteAddress)) { throw new SecurityException("Connecting from IP address " + remoteAddress+ " is not allowed" ); } super.addConnection(context, info); } }
安装插件:
package ch02.ptp; import java.util.List; import org.apache.activemq.broker.Broker; import org.apache.activemq.broker.BrokerPlugin; public class IPAuthenticationPlugin implements BrokerPlugin { List<String> allowedIPAddresses; public Broker installPlugin(Broker broker) throws Exception { return new IPAuthenticationBroker(broker, allowedIPAddresses); } public List<String> getAllowedIPAddresses() { return allowedIPAddresses; } public void setAllowedIPAddresses(List<String> allowedIPAddresses) { this.allowedIPAddresses = allowedIPAddresses; } }
ps:将这连个类打成jar包放到activemq的lib目录下
配置自定义插件:
<plugins> <bean xmlns="http://www.springframework.org/schema/beans" id="ipAuthenticationPlugin" class="org.apache.activemq.book.ch6.IPAuthenticationPlugin"> <property name="allowedIPAddresses"> <list> <value>127.0.0.1</value> </list> </property> </bean> </plugins>
