二、配置解读

1、从web.xml开始入手

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 >

classpath:alfresco/web-client-application-context.xml

classpath:web-services-application-context.xml

classpath:alfresco/web-api-application-context.xml

classpath:alfresco/application-context.xml

</ param-value >

< description > Spring config file locations </ description >

</ context-param >

web client 层

alfresco/web-client-application-context.xml

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

web api 层

alfresco/web-api-application-context.xml

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

web service 层

web-services-application-context.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。

bean 配置定义关键的文件

alfresco/application-context.xml

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

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

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

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

<!--

Import all modules and related components.

Extensions are explicitly imported after this so that the default

mechanism can still be used to override module-specific beans.

-->

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

<!--

Import of general extensions and bean overrides.

To give developers final control over the tuning

of their own local build, the dev-context.xml file

is processed last (note: dev-context.xml isn't

part of the source tree itself).

-->

< 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：

core-services-context.xml 核心 bean 的配置

看到配置了 JMX 的服务

< 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 >

< 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 >

< 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 >

< 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 >

< 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

< 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

authentication-services-context.xml

< 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

avm-services-context.xml

< 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。

workflow-context.xml 工作流相关的服务，JBPM

jcr-api-context.xml 实现JCR 170相关的API，即1.0版本的API

Alfresco implementation of a JCR Repository

avm-services-context.xml AVM相关服务，以及一堆的DAO

avm-console-context.xml

avm-console.properties 默认配置为本地MySQL的数据库

# Database specifics.

db.driver=org.gjt.mm.mysql.Driver

db.url=jdbc:mysql://127.0.0.1/avm

db.username=root

db.password=

db.pool.initial=4

db.pool.max=32

# Hibernate properties

hibernate.dialect=org.hibernate.dialect.MySQLInnoDBDialect

hibernate.current_session_context_class=thread

hibernate.connection.isolation=2

hibernate.default_batch_fetch_size=16

hibernate.jdbc.batch_versioned_data=true

hibernate.cache.use_second_level_cache=true

hibernate.hbm2ddl.auto=update

# AVM specific properties.

< import resource =" file:config/alfresco/avm-base-context.xml "/>

audit-services-context.xml

< bean id =" auditService " class =" org.alfresco.repo.audit.AuditServiceImpl ">

< property name =" auditComponent ">

< ref bean =" auditComponent "/>

</ property >

</ bean >

< bean id =" auditComponent " class =" org.alfresco.repo.audit.AuditComponentImpl ">

其后在 application-context.xml 还加载了

< import resource =" classpath*:alfresco/patch/*-context.xml " />一堆Patch，呵呵

patch-services-context.xml

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

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

module-context.xml 加载其它的模块Bean

最后加载一些扩展与二次开发的Bean

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

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

同时覆盖掉想覆盖的Bean，后面覆盖前面的，Map嘛。比如： custom-repository-context.xml 里的属性配置、资源配置、事务配置等

三、配置安装时的注意事项

1、要将 Alfresco 默认安装使用的数据库HSQL转换为MqSQL的话，只需要删掉三个 HSQL 使用的文件：

这三个文件分别是 tomcat/shared/classes/alfresco/extension 目录下的

custom-db-and-data-context.xml

custom-db-connection.properties

custom-hibernate-dialect.properties

为了产生一个MySQL数据库，执行 <alfresco_installation_folder>/extra/database/mysql ，运行 db_setup.bat 文件，或者打开文件，手工输入命令也一样。

就会产生一个与一个使用者一起命名 alfresco 的 MySQL 数据库帐户和一个 alfresco 的密码。

2、国际化

alfresco的文件路径为： WEB-INF/classes/alfresco/messages 下面包含了一堆文件，一个个去国际化吧，当然用插件、Native2ASCII或配合ANT都可以。

Eclipse 的 PropertiesEditor 插件不错。

3、无论从一种数据库切换到另一种数据库，都要记得把 repository.properties 配置文件里 dir.root 所在的目录下的文件删除干净，要不然会出问题。

比如：Caused by: org.alfresco.repo.search.SearcherException: More than one root node in index: 2

#dir.root=./alf_data

4、将 Win32NetBIOS.dll 拷贝到 %JAVA_HOME%/jre/bin/ 目录下或者 %TOMCAT_HOME%/bin 目录下

5、不要 ScriptService 的话，可以在 public-services-context.xml 中

注释掉 ScriptService 和 ScriptService_transaction

<!--

...

...

-->

6、查看 Hibernate 的 SQL

修改 log4j.properties

在 log4j.logger.org.hibernate 下增加一行，即可

log4j.logger.org.hibernate.SQL=debug

7、发现启动报 "Ensure that the 'dir.root' property is pointing to the correct data location." ... 之类的错误时可以在 repository.properties 配置文件里将 strict 设置为 false

# Change the failure behaviour of the configuration checker

system.bootstrap.config_check.strict=false

不过，设置后很有可能可以启动，但是仍是登录不了之类的，要小心。

如果用的是HSQL的话，最好把 alf_data/hsql_data 下面的 alfresco.properties 和 alfresco.script 恢复成原来的，并删除其它的文件，再重启就可以了。

8、第 7 条，仍报错 ERROR [repo.admin.ConfigurationChecker] CONTENT INTEGRITY ERROR: Indexes not found for 5 stores. 的话，设置为全部索引，并按第 3 条所说的删除文件，或者直接就换个文件夹，不要用默认的文件夹名称，并删除数据库的内容（所有的表以及HIBERNATE_SEQUENCE），并重启即可。

在 repository.properties 中设置

index.recovery.mode=FULL

9、如果是强行关闭掉Tomcat之类后，马上启动Tomcat的话，有可能会报错

IOException while loading persisted sessions: java.io.WriteAbortedException: writing aborted; java.io.NotSerializableException: org.alfresco.web.ui.common.component.UIListItem

过一会儿再启动就没有问题了。

10、Alfresco 2.0 需要 JDK 1.5_07 以上的版本，这个也要注意。

11、用户名大小字问题，可以在 repository.properties 进行设置

# Are user names case sensitive?

user.name.caseSensitive=true

设置为 true ，大小写敏感，默认为 false

12、关闭FTP服务，在 bootstrap-context.xml 配置中注释掉它就可以了。file-servers.xml里保存相关的配置信息

<!--

<constructor-arg>

</constructor-arg>

</bean>

-->

或者也可以在 file-servers.xml 文件中设置 <serverEnable enabled="false"/>

13、关闭CIFS服务

在 file-servers.xml 文件中设置 <serverEnable enabled="false"/> 即可。

四、数据库模型

可以看附件，有包含JBPM的与不包含JBMP的两个数据库

五、相关资料

Java Content Repository API 简介学习 JSR-170 如何使构建 CMA 变得轻而易举

http://www.ibm.com/developerworks/cn/java/j-jcr/

国外厂商纷纷投入开源界自述其中原因，此文重点介绍 Alfresco 的相关信息。

http://dotnet.csdn.net/n/20060206/86350.html

六、开发与代码分析

1、换 Web Services 的实现方式由 AXIS 换到 XFire

　　Codehaus XFire is a next-generation java SOAP framework. Codehaus XFire makes service oriented development approachable through its easy to use API and support for standards. It is also highly performant since it is built on a low memory StAX based model.
