activiti查询

一  1.根据当前任务id获得当前任务对象
  Task task = processEngine.getTaskService().createTaskQuery().taskId(taskId).singleResult();
2.根据流程id获得流程实例

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

3.根据任务id获得流程实例id

task.getProcessInstanceId();

4.根据任务id获得流程定义id

task.getProcessDefinitionId();

5.更具流程实例id获得流程

HistoricProcessInstance historicProcessInstance = historyService.createHistoricProcessInstanceQuery()

.processInstanceId(pProcessInstanceId).singleResult();

6.根据任务名字获得所有任务

List<Task> list = taskService.createTaskQuery()

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

7.添加批注信息

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

8.查询批注信息

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

9.获取历史流程实例

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

10.获得流程定义(根据历史流程实例id)

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

11.获得流程实例中已执行的节点

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

12.查询流程定

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