问题描述和代码已更新

问题1：我将如何替换下面代码中的虚拟int attachmentid = 123;以读取自定义属性sc：OpenERPattachmentID1以获取存储在其中的id值？ （问题1由alfrescian回答！）

//import com.openerp.model.scOpenERPModel;

public class DeleteAsset implements NodeServicePolicies.BeforeDeleteNodePolicy  {



    private PolicyComponent policyComponent;

    private Behaviour beforeDeleteNode;
    private NodeService nodeService;



    public void init() {

        this.beforeDeleteNode = new JavaBehaviour(this,"beforeDeleteNode",NotificationFrequency.EVERY_EVENT);

        this.policyComponent.bindClassBehaviour(QName.createQName(NamespaceService.ALFRESCO_URI,"beforeDeleteNode"), 

                QName.createQName(scOpenERPModel.NAMESPACE,scOpenERPModel.ASSET_CONTENT_TYPE), this.beforeDeleteNode);

    }
    public setNodeService(NodeService nodeService){
           this.nodeService = nodeService;  
        }




    @Override

    public void beforeDeleteNode(NodeRef node) {

        System.out.println("beforeDeleteNode!");

        try {
            QName attachmentID1= QName.createQName("http://www.someco.com/model/content/1.0", "OpenERPattachmentID1"); // this could/shoul be defined in your OpenERPModel-class
            int attachmentid = (Integer)nodeService.getProperty(node, attachmentID1);
            //int attachmentid = 123;
            URL oracle = new URL("http://0.0.0.0:1885/delete/%20?attachmentid=" + attachmentid);
            URLConnection yc = oracle.openConnection();
            BufferedReader in = new BufferedReader(new InputStreamReader(
                        yc.getInputStream()));
            String inputLine;
            while ((inputLine = in.readLine()) != null) 
            //System.out.println(inputLine);
                in.close(); 

        } catch(Exception e) {

            e.printStackTrace();

        }



    }

}

问题2：我在哪里放置DeleteAsset.class？

我是Java和Alfresco新手，如果有人能告诉我alfresco-4.2.c / tomcat / webapps / alfresco / WEB-INF / classes / com / openerp / behavior /是否合适，我会很高兴用于放置已编译的DeleteAsset.class的文件夹

问题3：我应该在NAMESPACE和ASSET_CONTENT_TYPE中添加什么内容？ 我想在没有模型课的情况下工作，因为我还没有教程，我该用scOpenERPModel.NAMESPACE,scOpenERPModel.ASSET_CONTENT_TYPE替换什么？

这是我的完整自定义网络上下文文件：

<?xml version='1.0' encoding='UTF-8'?>
 <!DOCTYPE beans PUBLIC '-//SPRING//DTD BEAN//EN'
 'http://www.springframework.org/dtd/spring-beans.dtd'>

 <beans>
<!-- Registration of new models -->
<bean id="smartsolution.dictionaryBootstrap" parent="dictionaryModelBootstrap"
 depends-on="dictionaryBootstrap">
    <property name="models">
        <list>
                <value>alfresco/extension/scOpenERPModel.xml</value>
        </list>
    </property>
</bean>

<!-- deletion of attachments within openERP when delete is initiated in Alfresco-->
<bean id="deletionBehavior" class="com.openerp.behavior.DeleteAsset" init-method="init">
    <property name="nodeService">
        <ref bean="nodeService" />
    </property>
    <property name="policyComponent">
        <ref bean="policyComponent" />
    </property>
</bean>

Answer 1

嗯，你还有很长的路要走...你想通过“oracle”连接达到什么目的？

回答您的主要问题：如何阅读财产：

不要将XML模型放入com / openerp / model / scOpenERPModel - 它应该是一个java类，它定义了访问自定义类型，方面和方法的常量。道具（例如：https://svn.alfresco.com/repos/alfresco-open-mirror/alfresco/HEAD/root/projects/data-model/source/java/org/alfresco/model/ContentModel.java）但这不是强制性的 - 它只是对你有帮助。

阅读属性

注入NodeService：

private NodeService nodeService;
public setNodeService(NodeService nodeService){
   this.nodeService = nodeService;  
}

QName attachmentID1= QName.createQName("your sc NS uri", "OpenERPattachmentID1"); // this could/shoul be defined in your OpenERPModel-class
int attachmentid = (Integer) nodeService.getProperty(node, attachmentID1);

从行为中读取文档属性的值
