Activit已办任务查询

Activit已办任务查询功能：

//获得当前用户

User user = (User) SecurityUtils.getSubject().getSession()

.getAttribute("userInfo");

//获得当前用户处理的历史流程实例

List<HistoricTaskInstance>  hisTaskList = historyService.createHistoricTaskInstanceQuery().taskAssignee(user.getId()).orderByTaskId().desc().list();

StringBuffer sbTask = new StringBuffer("");

Set<String> processInstanceIds = new HashSet<String>();

for(HistoricTaskInstance t : hisTaskList){

String processId = t.getProcessInstanceId();

sbTask.append("'").append(processId).append("',");

if(!processInstanceIds.contains(processId)){

processInstanceIds.add(processId);

}

}

System.out.println("***********sbTask="+sbTask.toString());

StringBuffer sbProcess = new StringBuffer("");

//根据历史流程实例，获得业务key

List<HistoricProcessInstance>  hisProcessList = historyService.createHistoricProcessInstanceQuery().processInstanceIds(processInstanceIds).orderByProcessInstanceId().desc().list();

for(HistoricProcessInstance p : hisProcessList){

String bizKey = p.getBusinessKey(); 

sbProcess.append("'").append(bizKey).append("',");

}

System.out.println("***********sbProcess="+sbProcess.toString());
