ESB架构的MULE(二)
最近又要使用MULE了。
其实我不是很喜欢这个东东,因为用的人少,资料比较少。
这次的应用主要是需要在受到POP3的邮件后,对取道邮件内容,根据邮件内容,连接数据库
查询资料,根据这个资料判断进入哪个ENDPOINT。
比较以前的MULE,增加了如下两个内容:
1、连接ORACLE数据库
2、在执行ENDPOINT的时候增加了一个判断
3、顺道把ACTIVEMQ的配置修改到了SPRING中
注意:
比较郁闷的是,一些比如ORACLE的驱动,IBATIS的JAR包都要拷贝到MULE的LIB的USER里面去,不然会找不到类
主要针对MULE的配置文件,email-config.xml做了修改:
<container-context
className="org.mule.extras.spring.SpringContainerContext"
name="spring">
<properties>
<property name="configFile"
value="classpath:/applicationContext.xml" />
</properties>
</container-context>
配置了,启动MULE的时候,启动SPRING的CONTAINER,
<connector name="activeMQConnector"
className="org.mule.providers.jms.JmsConnector">
<properties>
<property name="specification" value="1.1" />
<container-property name="connectionFactory"
reference="activeMqConnectionFactory" container="spring" />
</properties>
</connector>
ACTIVEMQ的配置转移到了SPRING的配置文件:applicationContext.xml中。
<model name="emailSample">
<mule-descriptor name="EmailActiveMQUM"
implementation="com.megaeyes.service.impl.EmailActiveMQManagerImpl">
<inbound-router>
<endpoint name="pop3email"
address="pop3://gateway:megaeyes@192.168.10.103"
transformers="EmailMessageTransformer">
<properties>
<property name="checkFrequency" value="10000" />
<property name="deleteReadMessages"
value="true" />
</properties>
</endpoint>
</inbound-router>
<outbound-router>
<router
className="com.megaeyes.utils.TransactionJoiningRouter">
<endpoint name="fileEndpoint" address="file:///d:/logs">
<properties>
<property name="filename" value="emailActiveMQ.txt" />
<property name="outputAppend" value="true" />
</properties>
</endpoint>
<endpoint name="jmsEndpointOne" address="jms://MessageOne"
connector="activeMQConnector" />
<endpoint name="jmsEndpointTwo" address="jms://MessageTwo"
connector="activeMQConnector" />
</router>
</outbound-router>
</mule-descriptor>
</model>
ENDPOINT里面的OUTBOUND-ROUTER做了改变,改为用自己类来处理:
com.megaeyes.utils.TransactionJoiningRouter
这里加入了根据内容来判断选择不同的ENDPOINT的机制,选择把结果存放到不同的队列MESSAGEONE或者MESSAGETWO中
在自己写的类
com.megaeyes.utils.TransactionJoiningRouter.java中:
UMOEndpoint endpoint = getEndpoint(i, message);
MessageBean o = (MessageBean) message.getPayload();
// System.out.println("message class name: "
// + o.getClass().getName());
// System.out.println("endpoint name: " + endpoint.getName());
// TODO use the name of the endpoint to check if proess
if (endpoint.getName().equalsIgnoreCase("fileEndpoint")) {
continue;
}
endpoint.setRemoteSync(false);
try {
dispatch(session, message, endpoint);
} catch (UMOException e) {
throw new CouldNotRouteOutboundMessageException(message,
endpoint);
}
可以得到MESSAGE中传递过来的信息,根据信息判断是否需要dispatch当前的ENDPOINT,当然ENDPOINT的名字在这里也可以得到
贴出完整的email-config.xml配置文件:

applicationContext.xml配置文件其实和spring的配置文件很相似:

<beans default-autowire="byName">

<bean id="emailJmsDao"

</beans>

1 楼 陈文景 2010-10-15 你好 我最近在入手这方面的东西
1、请问下 我暴露了一个axis的服务,客户端调用时,mule返回的是一个ArrayList
类型的对象,我试了一下,传回客户端没有问题 但是在客户端收到的message里却
不能解析,请问下我该怎么解析这个Arraylist呢,就是把其中保存的字符串打印出来。。
2、服务端回馈的信息是不是都是Object类型的呢,还有需要自己写格式解析类吗。。。
3、如果服务端要返回一个数据库查询后的结果集呢?
由于项目期限要到 十分紧急 希望您指点下 不胜感激 2 楼 陈文景 2010-10-15 我的qq是593194723 可以的希望您能加我 指点下我 。。。谢谢 3 楼 sillycat 2010-10-22 我当时直接传递的是自己的POJO,MessageBean o = (MessageBean),没有传递过ArrayList,你要测试一下。
