ActiveMQ4.1 +Spring2.0的POJO JMS方案(Jencks 版)
???? 作者：cctvx1
???? 此文檔僅適用于說明使用 Jecncks 和 使用Spring 2.0(DefaultMessageListenerContainer)? 充當MDP Container之間的區別,同時
演示Jecnks 的Spring 2.0 新配置實例。
????
1.引入ActiveMQ ResourceAdapter 和Jencks 的XSD
? 在ApplicationContext.xml(Spring的配置文件)中引入ActiveMQ ResourceAdapter 和Jencks 的XML Scheam 配置文件),如下:
?? ActiveMQ4.1 響應Spring 2.0號召，支持了引入XML Schema namespace的簡單配置語法，簡化了配置的語句。?
? 在ApplicationContext.xml(Spring的配置文件)中引入ActiveMQ的XML Scheam 配置文件),如下:
<
beans
??
xmlns
="http://www.springframework.org/schema/beans"
???xmlns:amq
="http://activemq.org/config/1.0"
???xmlns:ampra

???xmlns:jencks

??http://jencks.org/1.3?http://repository.codehaus.org/org/jencks/jencks/1.3/jencks-1.3.xsd"
>
?
由于ActiveMQ RA和Jencks?那個XSD 仍然有部分錯誤，因此使用的是自行修改過的XSD。(是xs:any元素引起的錯誤)
先在ClassPath根目錄放一個修改過的activemq-ra-4.1-incubator-SNAPSHOT.xsd和jencks-1.3.xsd。
同樣修改 ClassPath 下面META-INF\spring.schemas 增加內容如下。這個spring.schemas是spring自定義scheam的配置文件,請注意"http:\://"部分寫法

http\://repository.codehaus.org/org/jencks/jencks/1.3/jencks-1.3.xsd=/jencks-1.3.xsd

2. 配置方案
2.1?基礎零件?
1.?配置ActiveMQ Broker? 參見 ActiveMQ+Spring
?
2.?配置ActiveMQ Resource Adapter
<amqra:managedConnectionFactory id="jmsManagedConnectionFactory" resourceAdapter="#resourceAdapter"/><amqra:resourceAdapter id="resourceAdapter" serverUrl="vm: />
?
3.?配置Jencks 基礎配置
?? 具體的配置可以參見Jencks的XSD

<!--
?jencks?PoolFactory?config
-->

jencks:singlePoolFactory?
id

id

4.?配置給JmsTemplate使用的connectionFactory (主要是生成者/發送者 使用)
?? 這里注意下,在配置jmsTemplate的使用的targetConnectionFactory就是使用jencks配置的connectionManager
<!--
?spring?config?jms?with?jca
-->
?
<
bean?
id
="jmsManagerConnectionFactory"
?class
="org.springframework.jca.support.LocalConnectionFactoryBean"
>
??
<
property?
name
="managedConnectionFactory"
>
???
<
ref?
local
="jmsManagedConnectionFactory"
?
/>
??
</
property
>
??
<
property?
name
="connectionManager"
>
???
<
ref?
local
="connectionManager"
?
/>
??

bean?
class

????????
<
property?
name

?ref

?
/>
???
</
bean
>
??
</
property
>
??
<!--
?custom?MessageConverter?
-->
??
<
property?
name

?ref

?
/>
?
</
bean
>
?
?
5*.?配置Spring 2.0的MessageListenerAdapter,保證不需要用戶實現MessageListener*
?? 見ActiveMQ+Spring?
?6.配置Jecnks 充當MDP的Container
? 就是把上面的MessageListenerAdapter配置到Jencks里面,完成整個MDP的配置
?<!--?Jencks?Container-->
?<jencks:jcaContainer>??????<jencks:bootstrapContext>
???????????<jencks:bootstrapContextFactory?threadPoolSize="25"?/>
??????</jencks:bootstrapContext>
??????????<jencks:connectors>
??????????<!--?use?jencks?container?(use?spring?MessageListenerAdapter)-->
???????????<jencks:connector?ref="messageListener">
????????????????<jencks:activationSpec>
?????????????????????<amqra:activationSpec?destination="org.apache.activemq.spring.Test.spring.embedded"?destinationType="javax.jms.Queue"?/>
????????????????</jencks:activationSpec>
???????????</jencks:connector>??????</jencks:connectors>??????????<jencks:resourceAdapter>
???????????<amqra:resourceAdapter?serverUrl="vm://localhost"?/>
??????</jencks:resourceAdapter>
?</jencks:jcaContainer> ?
3. 說明
?? Spring 2.0本身使用DefaultMessageListenerContainer 可以充當MDP中的Container角色，但是鑒于Jencks是對于JCA標準,它不僅僅能夠提供jms的jca整合,包括其他資源比如jdbc都可以做到jca管理
所以,同時完成了這個ActiveMQ+Spring+Jencks 配置演示,更多的針對生產系統的JCA特性展示,會在稍后的開發計劃討論中確定。
