RuntimeService 運行服務類
支持啟動的方式

流程定義: 從這里獲取資源文件.

執行實例: 流程實例中執行的每個環節.流程實例: 一個流程實例包括所有運行的節點,一個流程中流程實例只有一個.

啟動一個實例:

public void startProcessInstanceByKey() {String processDefinitionKey = "leave";ProcessInstance processInstance = runtimeService.startProcessInstanceByKey(processDefinitionKey);System.out.println(processInstance.getId() + "," + processInstance.getActivityId());}

查詢該受理人的任務:

public void queryMyTask() {String processDefinitionKey = "leave";String assignee = "王五";List<Task> list = taskService.createTaskQuery().taskAssignee(assignee).processDefinitionKey(processDefinitionKey).list();}

完成任務:

public void completeMyTask() {String taskId = "54502";taskService.complete(taskId);}

查找運行實例的狀態:
方式1:

public void queryProcessInstanceState() {ProcessInstance processInstance = runtimeService.createProcessInstanceQuery().processInstanceId("59501")//.deploymentId().singleResult();if (processInstance != null) {System.out.println("當前流程實例正在運行");} else {System.out.println("當前流程實例已經結束");}}

方式2:

public void queryProcessInstanceState2() {String processInstanceId = "59501";HistoricProcessInstance historicProcessInstance = historyService.createHistoricProcessInstanceQuery().processInstanceId(processInstanceId).singleResult();if (historicProcessInstance.getEndTime() == null) {System.out.println("當前流程實例正在運行");} else {System.out.println("當前流程實例已經結束");}}

流程實例執行完成,相應的execution表中數據將被刪除.

查詢執行實例

public void createExecutionQuery() {List<Execution> executions = runtimeService.createExecutionQuery().list();for (Execution execution : executions) {System.out.println(execution.getId() + "," + execution.getActivityId());}}

查詢歷史流程實例:

public void createHistoricProcessInstanceQuery() {String processInstanceId = "59501";HistoricProcessInstance hpi = historyService.createHistoricProcessInstanceQuery().processInstanceId(processInstanceId).singleResult();System.out.println("流程定義ID：" + hpi.getProcessDefinitionId());System.out.println("流程實例ID：" + hpi.getId());System.out.println(hpi.getStartTime());System.out.println(hpi.getStartActivityId());System.out.println(hpi.getEndTime());}

查詢歷史活動實例:

public void createHistoricActivityInstanceQuery() {List<HistoricActivityInstance> list = historyService.createHistoricActivityInstanceQuery().list();for (HistoricActivityInstance hai : list) {System.out.println(hai.getId());}}

查詢歷史任務實例:

//select distinct RES.* from ACT_HI_TASKINST RES order by RES.ID_ ascpublic void createHistoricTaskInstanceQuery() {List<HistoricTaskInstance> list = historyService.createHistoricTaskInstanceQuery().list();}

設置流程發起人:

方式1 :

public void setAuthenticatedUserId1() {String authenticatedUserId = "朱元璋";identityService.setAuthenticatedUserId(authenticatedUserId);String processDefinitionKey = "leave";ProcessInstance processInstance = runtimeService.startProcessInstanceByKey(processDefinitionKey);System.out.println(processInstance.getId() + "," + processInstance.getActivityId());}

方式2 :

public void setAuthenticatedUserId2() {String authenticatedUserId = "朱重八";Authentication.setAuthenticatedUserId(authenticatedUserId);String processDefinitionKey = "leave";ProcessInstance processInstance = runtimeService.startProcessInstanceByKey(processDefinitionKey);System.out.println(processInstance.getId() + "," + processInstance.getActivityId());}

initiator結合流程實例啟動人使用:

啟動一個流程實例后會發現act_ru_variable會多出一條參數數據.

dataobject的使用:

部署相關的流程,啟動流程后variable表中添加3條數據

log4j.properties中配置(打印variable的日志信息):
獲取DataObject參數:

方式1:

/*** select * from ACT_RU_VARIABLE where EXECUTION_ID_ = ? and NAME_= ? and TASK_ID_ is null* - ==> Parameters: 77001(String), day(String)*/@Testpublic void getDataObject() {String executionId = "77001";String dataObject = "天數";DataObject dataObject1 = runtimeService.getDataObject(executionId, dataObject);if (dataObject1 != null) {System.out.println(dataObject1.getDataObjectDefinitionKey());System.out.println(dataObject1.getDescription());System.out.println(dataObject1.getExecutionId());System.out.println(dataObject1.getName());System.out.println(dataObject1.getValue());System.out.println(dataObject1.getType());}}

方式2:

/*** select * from ACT_RU_VARIABLE where EXECUTION_ID_ = ? and TASK_ID_ is null*/@Testpublic void getDataObject2() {String executionId = "77001";Map<String, DataObject> dataObject1 = runtimeService.getDataObjects(executionId);Set<Map.Entry<String, DataObject>> entries = dataObject1.entrySet();for (Map.Entry<String, DataObject> dataObjectEntry : entries) {DataObject dataObject = dataObjectEntry.getValue();if (dataObject != null) {System.out.println(dataObject.getDataObjectDefinitionKey());System.out.println(dataObject.getDescription());System.out.println(dataObject.getExecutionId());System.out.println(dataObject.getName());System.out.println(dataObject.getValue());System.out.println(dataObject.getType());}}}

流程實例的刪除以及級聯刪除:

@Testpublic void deleteProcessInstance() {String processInstanceId = "72001";String deleteReason = "我想刪除";runtimeService.deleteProcessInstance(processInstanceId, deleteReason);}//級聯刪除@Testpublic void deleteProcessInstanceCascade() {String processInstanceId = "69501";String deleteReason = "我想刪除";//processEngineConfiguration方式// ProcessEngineConfigurationImpl processEngineConfiguration = //(ProcessEngineConfigurationImpl) processEngine.getProcessEngineConfiguration(); //processEngineConfiguration.getExecutionEntityManager()//.deleteProcessInstance(processInstanceId,deleteReason,true);//DeleteProcessInstanceCaCadeCmd方式刪除managementService.executeCommand(new DeleteProcessInstanceCaCadeCmd(processInstanceId, deleteReason));}

獲取流程實例運行節點:

public void getActiveActivityIds() {String executionId = "77005";List<String> activeActivityIds = runtimeService.getActiveActivityIds(executionId); }

租戶方式部署以及啟動:

//根據流程定義的id啟動 public void startProcessInstanceById() {String processDefinitionId = "dataobject:1:74504";ProcessInstance processInstance = runtimeService.startProcessInstanceById(processDefinitionId); } //根據流程定義的key和租戶id public void startProcessInstanceByKeyAndTenantId() {ProcessInstance processInstance = runtimeService.startProcessInstanceByKeyAndTenantId("leave", "001"); }

自定義流程實例助手類:
首先,重寫里面的方法

//重寫MyProcessInstanceHelper集成ProcessInstanceHelper ,并重寫里面的方法 public class MyProcessInstanceHelper extends ProcessInstanceHelper {@Overridepublic ProcessInstance createProcessInstance(ProcessDefinition processDefinition, String businessKey, String processInstanceName, Map<String, Object> variables, Map<String, Object> transientVariables) {return super.createProcessInstance(processDefinition, businessKey, processInstanceName, variables, transientVariables);}@Overridepublic ProcessInstance createProcessInstance(ProcessDefinition processDefinition, String businessKey, String processInstanceName, String overrideDefinitionTenantId, Map<String, Object> variables, Map<String, Object> transientVariables, String callbackId, String callbackType, boolean startProcessInstance) {System.out.println("MyProcessInstanceHelper:createProcessInstance");return super.createProcessInstance(processDefinition, businessKey, processInstanceName, overrideDefinitionTenantId, variables, transientVariables, callbackId, callbackType, startProcessInstance);} }

然后,通過配置文件注入進來

<property name="processInstanceHelper" ><bean class="com.heima.bpmn.MyProcessInstanceHelper"></bean> </property>

流程定義的掛起與激活:

判斷流程定義是否被掛起

public void isProcessDefinitionSuspended() {String processDefinitionId = "leave:2:67004";boolean processDefinitionSuspended = repositoryService.isProcessDefinitionSuspended(processDefinitionId);System.out.println(processDefinitionSuspended); }

掛起一個流程實例

public void suspendProcessDefinitionById() {String processDefinitionId = "leave:2:67004";repositoryService.suspendProcessDefinitionById(processDefinitionId,true,null); }

釋放流程實例

public void activateProcessDefinitionById() {String processDefinitionId = "leave:2:67004";repositoryService.activateProcessDefinitionById(processDefinitionId); '}
