其它的略过，在 web.xml 中可以看到加载了如下 Spring 配置文件

<context-param>

            <param-name>contextConfigLocation</param-name>

            <param-value>

 </param-value>

            <description>Spring config file locations</description>

</context-param>

打开它可以看到它引入了所有的 alfresco/web-client*.xml & alfresco/extension/web-client*.xml & jar:*!/META-INF/web-client*.xml

打开它可以看到它引入了 alfresco/web-api-config.xml & alfresco/extension/web-api-config-custom.xml

刚开始找这个文件时，居然没有找到，怪事！not exist???why?

于是后来才发现这个文件是在 remote-api.jar 包里，晕，不是很好的做法啊。

    <import resource="classpath:alfresco/core-services-context.xml"/>

    <import resource="classpath:alfresco/public-services-context.xml"/>

    <import resource="classpath:alfresco/model-specific-services-context.xml"/>

    <import resource="classpath:alfresco/action-services-context.xml"/>

    <import resource="classpath:alfresco/rule-services-context.xml"/>

    <import resource="classpath:alfresco/node-services-context.xml"/>

    <import resource="classpath:alfresco/scheduled-jobs-context.xml"/>

    <import resource="classpath:alfresco/network-protocol-context.xml"/>

    <import resource="classpath:alfresco/content-services-context.xml"/>

    <import resource="classpath:alfresco/hibernate-context.xml"/>

    <import resource="classpath:alfresco/ownable-services-context.xml"/>

    <import resource="classpath:alfresco/template-services-context.xml"/>

    <import resource="classpath:alfresco/script-services-context.xml"/>

    <import resource="classpath:alfresco/index-recovery-context.xml"/>

    <import resource="classpath:alfresco/authority-services-context.xml"/>

    <import resource="classpath:alfresco/authentication-services-context.xml"/>

    <import resource="classpath:alfresco/policy-context.xml"/>

    <import resource="classpath:alfresco/import-export-context.xml"/>

    <import resource="classpath:alfresco/bootstrap-context.xml"/>

    <import resource="classpath:alfresco/workflow-context.xml"/>

    <import resource="classpath:alfresco/jcr-api-context.xml"/>

    <import resource="classpath:alfresco/avm-services-context.xml"/>

    <import resource="classpath:alfresco/audit-services-context.xml"/>

    <import resource="classpath*:alfresco/patch/*-context.xml"/>

    <import resource="classpath*:alfresco/domain/*-context.xml"/>

 

    <!--

    -->

    <import resource="classpath*:alfresco/module-context.xml"/>

 

    <!--

 

    -->

    <import resource="classpath*:alfresco/extension/*-context.xml"/>

    <import resource="classpath*:alfresco/extension/dev-context.xml"/>

 

可以看到分层次地进行加载不同的 bean ，并且在后面提供可扩展的 bean 定义的引入，方便进行扩展，而不需要更变这个配置文件

 

继续一个个往下看，并把一些重要的 bean 配置拿出来：

看到配置了 JMX 的服务

<!-- Custom MBeanServer -->

<bean id="alfrescoMBeanServer" class="org.springframework.jmx.support.MBeanServerFactoryBean"/>

 

<bean id="registry"   class="org.springframework.remoting.rmi.RmiRegistryFactoryBean">

    <property name="port" value="${avm.remote.port}"/>

</bean>

<!-- MBeanServer Connector (registers itself with custom alfrescoMBeanServer) -->

<bean id="serverConnector"

      class="org.springframework.jmx.support.ConnectorServerFactoryBean"

      depends-on="registry">

 

    <property name="server"      ref="alfrescoMBeanServer"/>

    <property name="objectName" value="connector:name=rmi"/>

    <property name="serviceUrl" value="service:jmx:rmi://localhost/jndi/rmi://localhost:${avm.remote.port}/alfresco/jmxrmi"/>

 

    <property name="environment">

        <map>

            <!-- The following keys are only valid when sun jmx is used -->

            <entry key="jmx.remote.x.password.file" value="${alfresco.jmx.dir}/alfresco-jmxrmi.password"/>

            <entry key="jmx.remote.x.access.file"   value="${alfresco.jmx.dir}/alfresco-jmxrmi.access"/>

        </map>

    </property>

</bean>

<!-- MBeans registered with alfrescoMBeanServer -->

<bean id="VirtServerRegistry"

      class="org.alfresco.mbeans.VirtServerRegistry"

      init-method="initialize">

 

JMX 服务暴露

<bean id="exporter" class="org.springframework.jmx.export.MBeanExporter">

  <property name="server" ref="alfrescoMBeanServer"/>

   <property name="beans">

     <map>

       <!-- MBeans to register with alfrescoMBeanServer -->

       <entry key="Alfresco:Name=VirtServerRegistry,Type=VirtServerRegistry" value-ref="VirtServerRegistry"/>

       <entry key="Alfresco:Name=FileServerConfig,Type=FileServerConfig" value-ref="FileServerConfig"/>

     </map>

   </property>

</bean>

 

同时暴露了 RMI 的服务

RMI

<!-- The RMI export of the repo remote transport. -->

<bean id="repoRemoteTransportRMI" class="org.springframework.remoting.rmi.RmiServiceExporter">

            <property name="service">

                        <ref bean="repoRemoteTransport"/>

            </property>

            <property name="serviceInterface">

                        <value>org.alfresco.service.cmr.remote.RepoRemoteTransport</value>

            </property>

            <property name="serviceName">

                        <value>repo</value>

            </property>

            <property name="registryPort">

                        <value>${avm.remote.port}</value>

            </property>

</bean>

 

验证 bean 配置，也是同时暴露了 RMI 的服务

<!-- Here for now. Probably want remote-context.xml file. -->

<!-- The AuthenticationService exported as an RMI service. -->

<bean id="rmiAuthenticationService" class="org.springframework.remoting.rmi.RmiServiceExporter">

            <property name="service">

                        <ref bean="AuthenticationService"/>

            </property>

            <property name="serviceInterface">

                        <value>org.alfresco.service.cmr.security.AuthenticationService</value>

            </property>

            <property name="serviceName">

                        <value>authentication</value>

            </property>

            <property name="registryPort">

                        <value>${avm.remote.port}</value>

            </property>

</bean>

 

avm 里也暴露了 RMI 的服务

<!-- The RMI wrapper around the AVM remote interface. -->

 

<bean id="avmRemoteService" class="org.springframework.remoting.rmi.RmiServiceExporter">

            <property name="service">

                        <ref bean="avmRemoteTransport"/>

            </property>

            <property name="serviceInterface">

                        <value>org.alfresco.service.cmr.remote.AVMRemoteTransport</value>

            </property>

            <property name="serviceName">

                        <value>avm</value>

            </property>

            <property name="registryPort">

                        <value>${avm.remote.port}</value>

            </property>

</bean>

<bean id="avmSyncServiceTransport" class="org.alfresco.repo.avm.AVMSyncServiceTransportImpl">

    <property name="authenticationService">

        <ref bean="AuthenticationService"/>

    </property>

    <property name="avmSyncService">

        <ref bean="AVMSyncService"/>

    </property>

</bean>

<bean id="avmSyncServiceTransportRMI" class="org.springframework.remoting.rmi.RmiServiceExporter">

    <property name="service">

        <ref bean="avmSyncServiceTransport"/>

    </property>

    <property name="serviceInterface">

        <value>org.alfresco.service.cmr.remote.AVMSyncServiceTransport</value>

    </property>

    <property name="serviceName">

        <value>avmsync</value>

    </property>

    <property name="registryPort">

        <value>${avm.remote.port}</value>

    </property>

</bean>

 

通过上面的 JMX 与 RMI 暴露在不同的配置文件里可以看到，如果我要去掉 JMX 或 RMI 服务的话，需要修改 N 个的配置文件，实在是麻烦。

建议要二次开发时根据需要进行整理，合并到一个文件里进行暴露即可，或者没有需要的话就直接 delete 掉这些：）

 

而且这个 JMX RMI 服务的暴露，导致你不能仅重启应用就可以，而非得重启整个应用服务器才行，要不然会报服务已启动，即默认的端口50500被占用了，而整个应用启动不了，麻烦。除非你在重启应用之前再去修改一下配置文件里的端口号，呵呵。

 

不过，最终的解决办法是象我在 Jmx4Log4J 里那样自己去再封装一个获取端口号的类，发现有人用了，就找下一个：）这样就ＯＫ了。
