JBPM4服務(wù)詳解

流程引擎ProcessEngine的構(gòu)建方式:

ProcessEngine pe = Configuration.getProcessEngine();
ProcessEngine pe = new Configuration().buildProcessEngine();
ProcessEngine pe = new Configuration().setResource("my.jbpm.cfg.xml").buildProcessEngine();

ProcessEngine pe = Configuration.getProcessEngine();
ProcessEngine pe = new Configuration().buildProcessEngine();
ProcessEngine pe = new Configuration().setResource("my.jbpm.cfg.xml").buildProcessEngine();

流程引擎的服務(wù)接口:

[java] view plain copy print ?

RepositoryService rs = pe.getRepositoryService();
ExecutionService es = pe.getExectionService();
TaskService ts = pe.getTaskService();
HistoryService hs = pe.getHistoryService();
ManagementService ms = pe.getManagementService();

RepositoryService rs = pe.getRepositoryService();
ExecutionService es = pe.getExectionService();
TaskService ts = pe.getTaskService();
HistoryService hs = pe.getHistoryService();
ManagementService ms = pe.getManagementService();

流程資源RepositoryService:包含了管理流程資源的所有方法.

1)部署流程

[java] view plain copy print ?

//通過(guò)classpath加載
rs.createDeployment().addResourceFromClasspath(path).deploy();
//通過(guò)File類加載
rs.createDeployment().addResourceFromFile(file).deploy();
//通過(guò)URL加載
rs.createDeployment().addResourceFromUrl(url).deploy();
//通過(guò)ZIP文件流加載
rs.createDeployment().addResourceFromZipInputStream(zip).deploy();
//通過(guò)字符串加載
rs.createDeployment().addResourceFromString(resourceName, string).deploy();

//通過(guò)classpath加載
rs.createDeployment().addResourceFromClasspath(path).deploy();
//通過(guò)File類加載
rs.createDeployment().addResourceFromFile(file).deploy();
//通過(guò)URL加載
rs.createDeployment().addResourceFromUrl(url).deploy();
//通過(guò)ZIP文件流加載
rs.createDeployment().addResourceFromZipInputStream(zip).deploy();
//通過(guò)字符串加載
rs.createDeployment().addResourceFromString(resourceName, string).deploy();

2)刪除流程

[java] view plain copy print ?

//刪除流程定義,如果該流程還存在活動(dòng)的流程實(shí)例,將拋出異常
rs.deleteDeployment(deploymentId);
//級(jí)聯(lián)刪除所有該流程相關(guān)的內(nèi)容
rs.deleteDeploymentCascade(deploymentId);

//刪除流程定義,如果該流程還存在活動(dòng)的流程實(shí)例,將拋出異常
rs.deleteDeployment(deploymentId);
//級(jí)聯(lián)刪除所有該流程相關(guān)的內(nèi)容
rs.deleteDeploymentCascade(deploymentId);

3)掛起/恢復(fù)流程

[java] view plain copy print ?

//掛起流程后,發(fā)起新流程或更新實(shí)例數(shù)據(jù)都會(huì)拋出異常
rs.suspendDeployment(deploymentId);
//恢復(fù)流程
rs.resumeDeployment(deploymentId);

//掛起流程后,發(fā)起新流程或更新實(shí)例數(shù)據(jù)都會(huì)拋出異常
rs.suspendDeployment(deploymentId);
//恢復(fù)流程
rs.resumeDeployment(deploymentId);

4)查詢流程定義信息

[java] view plain copy print ?

ProcessDefinitionQuery pdq = rs.createProcessDefinitionQuery();
List<ProcessDefinition> pdList = pdq.processDefinitionKey("xxx").list();

ProcessDefinitionQuery pdq = rs.createProcessDefinitionQuery();
List<ProcessDefinition> pdList = pdq.processDefinitionKey("xxx").list();

5)獲取流程定義圖片

[java] view plain copy print ?

//前提條件是圖片也發(fā)布到了數(shù)據(jù)庫(kù)中
rs.getResourceAsStream(deploymentId,"xxx.png");

//前提條件是圖片也發(fā)布到了數(shù)據(jù)庫(kù)中
rs.getResourceAsStream(deploymentId,"xxx.png");

執(zhí)行服務(wù)ExecutionService:主要用于維護(hù)流程實(shí)例,包含流程實(shí)例的查詢和流程變量的操作.

1)啟動(dòng)新的流程

[java] view plain copy print ?

//指定KEY,默認(rèn)最新版本
es.startProcessInstanceByKey("VMIN");
//指定KEY-流程版本
es.startProcessInstanceById("VMIN-2");
//指定流程實(shí)例ID
es.startProcessInstanceByKey("VMIN","CGD0008");
//傳遞流程變量
Map map = new HashMap();
es.startProcessInstanceByKey("VMIN", map);

//指定KEY,默認(rèn)最新版本
es.startProcessInstanceByKey("VMIN");
//指定KEY-流程版本
es.startProcessInstanceById("VMIN-2");
//指定流程實(shí)例ID
es.startProcessInstanceByKey("VMIN","CGD0008");
//傳遞流程變量
Map map = new HashMap();
es.startProcessInstanceByKey("VMIN", map);

2)執(zhí)行等待的流程

[java] view plain copy print ?

es.signalExecutionById(executeId);

es.signalExecutionById(executeId);

任務(wù)服務(wù)TaskService

1)任務(wù)列表訪問(wèn)

[java] view plain copy print ?

//查找指定用戶的任務(wù)列表
List<Task> list = ts.findPersonalTasks("marker");
//查找指定組的任務(wù)列表
List<Task> list = ts.findGroupTasks("hr-group");

//查找指定用戶的任務(wù)列表
List<Task> list = ts.findPersonalTasks("marker");
//查找指定組的任務(wù)列表
List<Task> list = ts.findGroupTasks("hr-group");

2)讀取相關(guān)數(shù)據(jù)

[java] view plain copy print ?

ts.getVariable(taskId, variableName);
ts.getVariables(taskId, variableNames);
ts.getVariableNames(taskId);
ts.getVariables(taskId, variables);

ts.getVariable(taskId, variableName);
ts.getVariables(taskId, variableNames);
ts.getVariableNames(taskId);
ts.getVariables(taskId, variables);

3)完成任務(wù)

[java] view plain copy print ?

ts.completeTask(taskId);
ts.completeTask(taskId, variables);
ts.completeTask(taskId, outcome);
ts.completeTask(taskId, outcome, variables);

ts.completeTask(taskId);
ts.completeTask(taskId, variables);
ts.completeTask(taskId, outcome);
ts.completeTask(taskId, outcome, variables);

歷史服務(wù)HistoryService:查詢歷史流程實(shí)例

[java] view plain copy print ?

hs.createHistoryProcessInstanceQuery().processDefinitionId(pdId).orderAsc(HistoryProcessInstanceQuery.PROPERTY_STARTTIME).list();

hs.createHistoryProcessInstanceQuery().processDefinitionId(pdId).orderAsc(HistoryProcessInstanceQuery.PROPERTY_STARTTIME).list();

管理服務(wù)ManagementServcie:管理Job

[java] view plain copy print ?

Job job = ms.createJobQuery().processInstanceId(processInstanceId).uniqueResult();
ms.executeJob(job.getId);
