开发ActiveMQ的插件BrokerPlugin

       两个步骤：参考地址：http://activemq.apache.org/interceptors.html

       1、开发插件类

                 插件类需要实现接口org.apache.activemq.broker.BrokerPlugin

                 activeMQ已有的实现类，如下

                 继承：org.apache.activemq.broker.BrokerPluginSupport=》BrokerFilter类=》BrokerPlugin接口

import org.apache.activemq.broker.Broker;
import org.apache.activemq.broker.BrokerPlugin;

public class MyPlugin implements BrokerPlugin {	
        
        public Broker installPlugin(Broker broker) throws Exception {            
             return new MyBroker(broker);
        }	

}

 

 

       2、配置activeMQ

  

 
<broker xmlns="http://activemq.org/config/1.0" brokerName="localhost" dataDirectory="${activemq.base}/data">

  <!-- The transport connectors ActiveMQ will listen to -->
  <transportConnectors>
     <transportConnector name="openwire" uri="tcp://localhost:61616" />
  </transportConnectors>

  <plugins>
      <bean id="myPlugin" class="org.myorg.MyPlugin"/>    
  </plugins>

 </broker>

 

 

======================

今天重新测试了一下，发现XML解析有问题，可是看activemq.xsd是OK的呀，也没有顺序才是。实现是想不出怎么做。完全按照教程上来的也解释有问题，可能是一个小细节或者包冲突导致。

      但是没有时间去细化问题，只想了一个绕过去的办法——本身activemq的配置文件是基于spring来实现的。那完全可以通过spring在broker实例化之前加上plugins配置信息。
