Question

为了获得公司，我使用这种方法：

public NodeRef getCompanyHome()

    {
        return nodeLocatorService.getNode("companyhome", null, null);
    }

弹簧配置如下：

<bean id="TransformationHandler" class="org.alfresco.transformation.TransformationHandler"          parent="baseJavaDelegate" lazy-init="default" autowire="default" dependency-check="default">
      <property name="nodeService" ref="NodeService" />
      <property name="nodeLocatorService" ref="nodeLocatorService" />
</bean>

当我循环访问NodeRef的孩子时，我看到根文件夹结构（我不是因为我用英语命名它们）：数据字典，访客目录，用户家庭空间，已发布等等。但是当我在工作流程中运行代码时，我需要获取附加到工作流程的文件。这样做的方法是什么？我也对配置工作流模型感兴趣，因为在tutorial中有关于bpm：package的信息很少，bpm:packageItemActionGroup是唯一可以找到bpm：包的地方。这够了吗？

<type name="scwf:activitiApprovedNotification">
    <parent>bpm:workflowTask</parent>
    <overrides>
        <property name="bpm:packageItemActionGroup">
            <default>read_package_item_actions</default>
        </property>
    </overrides>
</type>

？所以有两个问题：访问bpm：package的内容的方法是什么？是否为此目的提供了工作流模型的上述部分？

访问工作流内容的一种方法是为其编写webscript。以下是java支持的webscript访问某些工作流程详细信息的示例：

<强> workflowdetails.get.json.ftl

<webscript>
   <shortname>Get Workflow Task</shortname>
   <description>Retrieves all the workflow tasks which are in progress</description>
   <url>/workflow/details</url>
   <format default="json"/>
   <authentication>user</authentication>
   <transaction allow="readonly">required</transaction>
   <lifecycle>public_api</lifecycle>
</webscript>

<强> WorkflowActiveTaskDetails.java

package util.workflow;

public class WorkflowActiveTaskDetails extends DeclarativeWebScript {
    ServiceRegistry serviceRegistry;

    public void setServiceRegistry(ServiceRegistry serviceRegistry) {
        this.serviceRegistry = serviceRegistry;
    }

    protected Map<String, Object> executeImpl(WebScriptRequest arg0, Status status, Cache cache) {
        WorkflowService workflowService = serviceRegistry.getWorkflowService();
        NodeService nodeService=serviceRegistry.getNodeService();
        JSONArray arr = new JSONArray();
        Map<String, Object> model = new HashMap<String, Object>();

        WorkflowTaskQuery tasksQuery = new WorkflowTaskQuery();
        tasksQuery.setTaskState(WorkflowTaskState.IN_PROGRESS);
        tasksQuery.setActive(true);
        List<WorkflowTask> tasks = workflowService.queryTasks(tasksQuery);

        for(int i=0;i<tasks.size();i++) {
            JSONObject jsondata = new JSONObject();
            Map<QName, Serializable> properties= tasks.get(i).getProperties();
            try {
                Date dueDate=tasks.get(i).getPath().getInstance().getDueDate();
                jsondata.put("duedate", dueDate!=null?dueDate.toString().split(" ")[0]:"");
                jsondata.put("priority",tasks.get(i).getPath().getInstance().getPriority());    jsondata.put("initiator",nodeService.getProperty(tasks.get(i).getPath().getInstance().getInitiator(),ContentModel.PROP_FIRSTNAME));
                jsondata.put("description",properties.get(WorkflowModel.PROP_DESCRIPTION));
                arr.put(jsondata);
            } catch (JSONException e) {
                e.printStackTrace();
            }
        }
        model.put("data", arr);
        return model;
    }
}

<强> workflowdetails.get.json.ftl

{data}

Bean配置：

<bean id="webscript.util.workflow.WorkflowActiveTaskDetails.get" class="util.workflow.WorkflowActiveTaskDetails" parent="webscript">
    <property name="serviceRegistry" ref="ServiceRegistry" />
</bean>

你会得到像

这样的回复

[{"initiator":"test5","description":"Test Workflow","priority":2,"duedate":"2014-03-29"},{"initiator":"test5","description":"Test Workflow2","priority":1,"duedate":"2014-03-31"}]

如何从java访问当前工作流的bpm包？
