一 1.根據當前任務id獲得當前任務對象
Task task = processEngine.getTaskService().createTaskQuery().taskId(taskId).singleResult();
2.根據流程id獲得流程實例

ProcessInstance pi =processEngine.getRuntimeService().createProcessInstanceQuery().processInstanceId(task.getProcessInstanceId()).singleResult();

3.根據任務id獲得流程實例id

task.getProcessInstanceId();

4.根據任務id獲得流程定義id

task.getProcessDefinitionId();

5.更具流程實例id獲得流程

HistoricProcessInstance historicProcessInstance = historyService.createHistoricProcessInstanceQuery()

.processInstanceId(pProcessInstanceId).singleResult();

6.根據任務名字獲得所有任務

List<Task> list = taskService.createTaskQuery()

.taskCandidateOrAssigned("userId").list();

7.添加批註信息

taskService.addComment(taskId, task.getProcessInstanceId(), message);

8.查詢批註信息

List<Comment> list = taskService.getProcessInstanceComments(task.getProcessInstanceId());

9.獲取歷史流程實例

HistoricProcessInstance historicProcessInstance = historyService.createHistoricProcessInstanceQuery()
.processInstanceId(pProcessInstanceId).singleResult();

10.獲得流程定義(根據歷史流程實例id)

ProcessDefinitionEntity processDefinition = (ProcessDefinitionEntity) ((RepositoryServiceImpl) repositoryService)
.getDeployedProcessDefinition(historicProcessInstance.getProcessDefinitionId());

11.獲得流程實例中已執行的節點

List<HistoricActivityInstance> historicActivityInstanceList = historyService.createHistoricActivityInstanceQuery()
.processInstanceId(pProcessInstanceId).orderByHistoricActivityInstanceId().asc().list();

12.查詢流程定

List<ProcessDifintion> list = processEngine.getRepositoryService.CreateProcessDefinitionQuery().processDefinitionId(processDefifinitionId).list();
