从Maven项目中的Alfresco中删除远程跟踪图像

Question

Alfresco 3.2c有一个跟踪图像，它被注入到使用Javascript的页脚，我需要删除一个项目。javascript实际上是硬编码在类org/alfresco/web/scripts/MessagesWebScript.java的alfresco-share-src.zip的SDK中。

我们目前正在使用Maven项目构建Alfresco，它从Maven插件和存储库中提取了大部分Alfresco和Share，给了我们一个干净的根构建添加。然而，由于这个类是硬编码的，我们不想触摸原始的jar/zip，我想我可以只是添加一个新的文件副本到share/src/main/java/org/alfresco/web/scripts/MessagesWebScript.java，将其编译成war文件的WEB-INF，从而覆盖将从jar加载的内容(是的，我知道这样做的坏方法)。

然而，如果我只是添加文件，我得到错误/share/src/main/java/org/alfresco/web/scripts/MessagesWebScript.java:[48,80] error: cannot find symbol在行

public class MessagesWebScript extends org.springframework.extensions.webscripts.MessagesWebScript

这让我相信它没有拉入用于构建war文件的相同依赖项(即spring-surf-parent依赖项)。如果我尝试将依赖项添加到共享中。pom文件(如下所示)，maven成功构建，但是依赖项以某种方式拉入servlet API jar文件，将它们添加到war中，然后我得到预期的The method getJspApplicationContext(ServletContext) is undefined for the type JspFactory错误。

    <dependency>
            <groupId>org.springframework.extensions.surf</groupId>
            <artifactId>spring-surf-parent</artifactId>
            <version>1.2.0-M3</version>
    </dependency>

Answer 1

如果我理解正确的话，您想要覆盖单个Java类，在这种情况下，恰好实现了web脚本，但是您的解决方案是用这个类的分叉副本重新包装share WAR。

重新定义核心Alfresco(或Share)类是一个坏主意。这个web脚本是在webapp类路径下的Spring配置文件alfresco/slingshot-application-context.xml中声明的，因此你应该做的是在alfresco/web-extension下的*-context.xml文件中重写它，例如

<?xml version='1.0' encoding='UTF-8'?>
<beans xmlns="http://www.springframework.org/schema/beans"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xsi:schemaLocation="
       http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
   <!--  I18N resources and messages Web Script -->
   <bean id="webscript.org.springframework.extensions.messages.get" 
         parent="webscript" 
         class="my.custom.namespace.MessagesWebScript">
      <property name="webFrameworkConfigElement" ref="webframework.config.element"/>
      <property name="dependencyHandler" ref="dependency.handler"/>
   </bean>
</beans>

没有理由不从一开始就通过Spring实现重写。Spring bean就是为此目的而设计的，它增加的工作量很少，但如果它没有按预期工作，则可以更有效地进行调试。

显然，您还需要确保您的自定义类my.custom.namespace.MessagesWebScript作为构建的一部分进行编译，并且听起来目前还没有这样做。这可能是因为你的POM中缺少一些JAR(而不是WAR)依赖关系——看看我们使用的Google Docs集成共享POM。

最后，我建议您将您的定制包作为AMP文件。Alfresco Maven SDK对此提供了完全的支持，你只需要将它声明为父节点——参见Google Docs的父节点POM示例。
