流程中往往需要特定人接受任務并進行一定操作才能繼續進行下去。

　　代碼如下

import java.io.InputStream;import org.activiti.engine.ProcessEngine; import org.activiti.engine.ProcessEngines; import org.activiti.engine.repository.Deployment; import org.activiti.engine.runtime.Execution; import org.activiti.engine.runtime.ProcessInstance; import org.junit.Test;public class ReceiveTaskTest {ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();/**部署流程定義（從inputStream）*/@Testpublic void deploymentProcessDefinition_inputStream(){InputStream inputStreamBpmn = this.getClass().getResourceAsStream("receiveTask.bpmn");InputStream inputStreamPng = this.getClass().getResourceAsStream("receiveTask.png");Deployment deployment = processEngine.getRepositoryService()//與流程定義和部署對象相關的Service.createDeployment()//創建一個部署對象.name("接收活動任務")//添加部署的名稱.addInputStream("receiveTask.bpmn", inputStreamBpmn)// .addInputStream("receiveTask.png", inputStreamPng)// .deploy();//完成部署System.out.println("部署ID："+deployment.getId());// System.out.println("部署名稱："+deployment.getName());// }/**啟動流程實例+設置流程變量+獲取流程變量+向后執行一步*/@Testpublic void startProcessInstance(){//流程定義的keyString processDefinitionKey = "receiveTask";ProcessInstance pi = processEngine.getRuntimeService()//與正在執行的流程實例和執行對象相關的Service.startProcessInstanceByKey(processDefinitionKey);//使用流程定義的key啟動流程實例，key對應helloworld.bpmn文件中id的屬性值，使用key值啟動，默認是按照最新版本的流程定義啟動System.out.println("流程實例ID:"+pi.getId());//流程實例ID 101System.out.println("流程定義ID:"+pi.getProcessDefinitionId());//流程定義ID helloworld:1:4/**查詢執行對象ID*/Execution execution1 = processEngine.getRuntimeService()// .createExecutionQuery()//創建執行對象查詢.processInstanceId(pi.getId())//使用流程實例ID查詢.activityId("receivetask1")//當前活動的id，對應receiveTask.bpmn文件中的活動節點id的屬性值 .singleResult();/**使用流程變量設置當日銷售額**/processEngine.getRuntimeService().setVariable(execution1.getId(), "匯總當日銷售額", 21000);/**向后執行一步，如果流程處于等待狀態，使得流程繼續執行*/processEngine.getRuntimeService().signal(execution1.getId());/**查詢執行對象ID*/Execution execution2 = processEngine.getRuntimeService()// .createExecutionQuery()//創建執行對象查詢.processInstanceId(pi.getId())//使用流程實例ID查詢.activityId("receivetask2")//當前活動的id，對應receiveTask.bpmn文件中的活動節點id的屬性值 .singleResult();/**從流程變量中獲取匯總當日銷售額的值*/Integer value = (Integer)processEngine.getRuntimeService()// .getVariable(execution2.getId(), "匯總當日銷售額");System.out.println("給老板發送短信：金額是："+value);/**向后執行一步，如果流程處于等待狀態，使得流程繼續執行*/processEngine.getRuntimeService().signal(execution2.getId());}}

　　由于沒有任務id，因此只能由流程進行操作，所以使用getRuntimeService()方法。先由流程實例編號查詢流程1，并進行匯總銷售操作然后進行到下一個流程。同樣，由流程實例編號查詢流程2，匯報給老板并進行到下一步完成整個流程
