如何获得有效的 Alfresco 应用程序上下文来创建文件夹？

Question

我正在修改 InboundSMTP 以便为新邮件创建文件夹。似乎需要 fileFolderService.create，以及文件夹内容类型的参数。从那开始我需要一个 ServiceRegistry，它又需要 ApplicationContext。

这是我正在尝试做的事情：

ApplicationContext appContext = new ClassPathXmlApplicationContext("alfresco/application-context.xml");
ServiceRegistry serviceRegistry = (ServiceRegistry) appContext.getBean(ServiceRegistry.SERVICE_REGISTRY);
FileFolderService fileFolderService=serviceRegistry.getFileFolderService();
FileInfo object = fileFolderService.create(nodeRef, messageSubject, ContentModel.TYPE_FOLDER);

但是，这会导致入站电子邮件被拒绝。我可以注释掉最后 3 行，但它仍然以同样的方式失败，所以我的 ApplicationContext 调用有问题。即使只是那个调用，我也会收到以下错误（这对我来说毫无意义）：

我在尝试获取 ApplicationContext 时做错了什么？或者，我是否应该尝试另一种 approach/is 在 Alfresco 中以编程方式创建文件夹的 更好的 方法？

Answer 1

在这种情况下，您不需要注入应用程序上下文。

修改电子邮件处理的最佳做法涉及创建自定义处理程序。下面是定义这个的重要代码：

public class CustomFolderEmailMessageHandler extends AbstractEmailMessageHandler {

    public void processMessage(NodeRef nodeRef, EmailMessage message) {
        NodeService nodeService = getNodeService();
    }

}

抽象 class 有一个 getNodeService() 方法，它为您提供节点服务。这是 FileFolderService 的详细版本。

您应该使用 FolderEmailMessageHandler 作为指南：https://svn.alfresco.com/repos/alfresco-open-mirror/alfresco/HEAD/root/projects/repository/source/java/org/alfresco/email/server/handler/FolderEmailMessageHandler.java

为了注册您的消息处理程序，您需要覆盖 emailService bean： https://wiki.alfresco.com/wiki/Inbound_SMTP_Email_Server_Configuration#Implementing_A_Custom_Node_Handler

Answer 2

您几乎肯定不想获取您需要执行的应用程序上下文！

如果你想要 "all the common services"，请不要获取上下文。相反，请 Spring 给你 Alfresco ServiceRegistry。它可以作为 ID 为 ServiceRegistry 的 bean 提供，并且为您可能需要的主要服务提供方便的 getter

但在你的情况下，如果你知道你想要 FileFolderService，请向 spring 索取你的豆子！如果您要覆盖 documentEmailMessageHandler bean（例如），您需要一个像这样的 bean：

<bean id="documentEmailMessageHandler"
      parent="emailMessageHandlerBase"
      class="com.something.else.DocumentEmailMessageHandler">
   <property name="fileFolderService" ref="FileFolderService"/>
</bean>

然后在您的自定义实现中，提供一个方法 setFileFolderService(FileFolderService fileFolderService) 来保存服务供以后使用。如果这对您来说是新的，请遵循任何标准 spring 教程！

如果您确实确实需要 Spring 应用程序上下文，请遵循正常的 Spring 模式并让您的 bean class 实现 ApplicationContextAware interface，并且 spring 将在初始化期间为您设置上下文
