Activiti工作流--并行网关--之九

流程的业务描述 会议记录会签

并行网关是不需要设置流程变量的，并行网关不在流程变量的范围内

比如:
在开完某个产品设计会以后,需要对会议约定一些事项进行签字画押涉及到两个部门(产品部/研发部)的主管和经理
确认的顺序:
a:产品部的主管确认然后产品部的经理确认
b:研发部的主管确认 然后研发部的经理确认
注意:以上两个处理步骤可以同时进行,都完成以后,代表流程结束

先获取连接

private ProcessEngine processEngine;
	
@Before
public void intiProcessEngine(){
	processEngine = ProcessEngines.getDefaultProcessEngine();
}

流程定义与部署

@Test
public void testProcessEngine(){
	Deployment deployment = processEngine.getRepositoryService()
								.createDeployment()
								.addClasspathResource("diagram/parallelGateWay.bpmn")
								.addClasspathResource("diagram/parallelGateWay.png")
								.name("并行会签")
								.deploy();
	System.out.println("流程部署ID："+deployment.getId());//152501
	System.out.println("流程部署名称："+deployment.getName());
}

启动流程

@Test
public void testStartTask(){
	String processDefinitionKey = "parallelGateWay";
	ProcessInstance processInstance = processEngine.getRuntimeService()
			.startProcessInstanceByKey(processDefinitionKey);
	System.out.println("流程部署ID："+processInstance.getDeploymentId());
	System.out.println("流程定义ID："+processInstance.getProcessDefinitionId());
	System.out.println("流程实例ID："+processInstance.getProcessInstanceId());//155001
}

查询个人,完成个人任务

/**
 * 流程处理过程：查询个人任务
 */
@Test
public void testTaskQuery(){
	String assignee = "赵六";
	String processInstanceId = "155001";
	List<Task> taskList = processEngine.getTaskService()
							.createTaskQuery()
							.taskAssignee(assignee)
							.processInstanceId(processInstanceId)
							.list();
	if (taskList != null && taskList.size() > 0) {
		for (Task task : taskList) {
			System.out.println("流程定义ID："+task.getProcessDefinitionId());
			System.out.println("流程实例ID："+task.getProcessInstanceId());
			System.out.println("执行对象ID："+task.getExecutionId());
			System.out.println("任务ID："+task.getId());//155007

}

/**

 */
@Test
public void testCompleteTask(){
	String taskId = "162502";
	processEngine.getTaskService().complete(taskId);
	System.out.println("财务主管审批完成");
}

/**
 * 在流程的执行过程中，我们需要查询流程执行到了哪一个状态
 * 查询的是act_ru_execution  流程实例表
 * 当流程结束了  那么在act_ru_execution 在这张表中就没有了数据记录
 */
@Test
public void testQueryProinsatanceState(){
	String processInstanceId = "155001";
	ProcessInstance singleResult = processEngine.getRuntimeService()
										.createProcessInstanceQuery()
										.processInstanceId(processInstanceId)
										.singleResult();
	if (singleResult != null) {

总结

并行网关的分支和汇聚都是同一个图元符号(图标)
并行网关不会解析条件,所以流程变量的设置不会引起流程的其他选择
并行网关的分支里面可以再进行分支和聚合
