activity5工作流相关内置对象获取与应用

• activity5 流程初始化，与启动

Map<String, Object> variables = new HashMap<String,Object>();variables.put("userid", "1");//设置用户variables.put("auditValue", "ok");//设置审批结果// 加载配置文件activiti.cfg.xml，创建引擎，如果出现null，多半是加载路径不是根目录。 //获取配置文件后，引擎开始创建数据库。//ProcessEngine engine = ProcessEngines.getDefaultProcessEngine();// 获取流程储存服务组件 RepositoryService rs=engine.getRepositoryService();// 获取运行时服务组件 RuntimeService rse=engine.getRuntimeService();// 获取流程中的任务TASK组件 TaskService ts=engine.getTaskService();// 部署流程，只要是符合BPMN2规范的XML文件，理论上都可以被ACTIVITI部署//rs.createDeployment().addClasspathResource("/diagrams/event/event_new.bpmn").deploy();// 开启流程，myprocess是流程的ID ProcessInstance pi = rse.startProcessInstanceByKey("event_new", variables);//获取流程定义对象ProcessDefinitionEntity pde= (ProcessDefinitionEntity) engine.getRepositoryService().getProcessDefinition(pi.getProcessDefinitionId());//获取环节对象ActivityImpl activityImpl = pde.findActivity("eventAudit");//获取来往sequenceflow路线List<PvmTransition> inpvmlist = pde.findActivity("eventAudit").getIncomingTransitions();//获取去往sequenceflow路线List<PvmTransition> outpvmlist = pde.findActivity("eventAudit").getOutgoingTransitions();//不知道得到nullIOSpecification iOSpecification = pde.findActivity("eventAudit").getIoSpecification();//获取流程定义范围ScopeImpl scopeImpl = pde.findActivity("eventAudit").getParent();//获取父节点ActivityImpl pActivityImpl = pde.findActivity("eventAudit").getParentActivity();//获取sequenceflowTransitionImpl transitionImpl = pde.findActivity("eventAudit").findOutgoingTransition("flow37");

• 获取任务ID

// 获取运行时服务组件 RuntimeService rse=engine.getRuntimeService();// 获取流程中的任务TASK组件 TaskService ts=engine.getTaskService();String processInstanceId = request.getParameter("processInstanceId");List<IdentityLink> linkList =rse.getIdentityLinksForProcessInstance(processInstanceId);List<Task> taskList = ts.createTaskQuery().processInstanceId(processInstanceId).list();String taskId = taskList.get(0).getId();

• 流程审批

// 获取流程中的任务TASK组件 TaskService ts=engine.getTaskService();String taskId = request.getParameter("taskId");String processInstanceId = request.getParameter("processInstanceId");String auditResult = request.getParameter("auditResult");Map<String, Object> resultMap = new HashMap<String, Object>();resultMap.put("userid", "1");resultMap.put("auditValue", auditResult);ts.complete(taskId, resultMap);
