osworkflow中 常用的一些方法

 轉自:snake_liu專欄

1、啟動流程

  Workflow workflow = new BasicWorkflow(userID);//userID啟動流程的使用者
  DefaultConfiguration config = new DefaultConfiguration();
  workflow.setConfiguration(config);
   workflowId = workflow.initialize("myworkflow", 0, null); //myworkflow--workflow.xml中定義的流程名

2、將流程流轉到指定的步驟

  Workflow workflow = new BasicWorkflow(userID);
  DefaultConfiguration config = new DefaultConfiguration();
  workflow.setConfiguration(config);
   workflow.doAction(workflowId, actionId, null);//actionID指定的action

3、查詢已經完成的流程號

Query類：getCompleted() 方法：
public List getCompleted() {
              
  FieldExpression fe = new FieldExpression(FieldExpression.STATE,
   FieldExpression.ENTRY,
   FieldExpression.EQUALS,
   new Integer(WorkflowEntry.COMPLETED));
  List list = null;
  try {
   list = getPersistence().query(new WorkflowExpressionQuery(fe));
  } catch (StoreException e) {
   e.printStackTrace();
  }

  return list;
 }

頁面顯示：

<%
Query query = new Query();
List completed = query.getCompleted();
for(int i=0; i<completed.size(); i++) {
 Long wfId = (Long) completed.get(i);
 out.println("workflow id => " + wfId + "<br>");
}
%>

4、取得使用者的代辦資訊：

public List getPendingJob(String userID){
   
        List list = null;
       
        WorkflowExpressionQuery weq = new WorkflowExpressionQuery(new FieldExpression(FieldExpression.OWNER,
                FieldExpression.CURRENT_STEPS,FieldExpression.EQUALS,userID));
       
        try {
   list = getPersistence().query(weq);
   System.out.println(list.size());
  } catch (StoreException e) {
   e.printStackTrace();
  }
  return list;
    }

頁面顯示：

<%
List pd = query.getPendingJob(request.getParameter("userID"));
for(int i=0; i<pd.size(); i++) {
 Long wfId = (Long) pd.get(i);
 out.println("workflow id => " + wfId + "<br>");
}
%>
