Activiti工作流--流程变量的应用之二：排他网关--之八

流程的业务描述

财务报账审批流程:
a: 如果报账金额大于5000和小于10000时,财务审批以后,交由财务主管审批,然后结束流程
b: 如果报账金额大于或者等于10000,财务审批完以后交由财务经理审批,然后结束流程
c: 如果是其他情况,直接结束流程

先获取连接

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

流程定义与部署

@Test
public void tetsProcessDelopment(){
	Deployment deployment = processEngine.getRepositoryService()
					.createDeployment()
					.addClasspathResource("diagram/exclusiveGateWay.bpmn")
					.addClasspathResource("diagram/exclusiveGateWay.png")
					.name("排他网关审批")
					.deploy();
	System.out.println("流程部署ID："+deployment.getId());//127501
	System.out.println("流程部署名称：" +deployment.getName());
}

启动流程

@Test
public void testStartProcess(){
	String processDefinitionKey = "exclusiveGateWay";
	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());//145001
}

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 = "张三";
	String processInstanceId = "145001";
	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());//145004
			System.out.println("任务名称："+task.getName());
			System.out.println("任务创建时间："+task.getCreateTime());
		}
	}
}

/**
 * 流程处理过程：完成个人任务
 */
@Test
public void testCompleteTask(){
	String taskId = "145004";
	Map<String, Object> map = new HashMap<String,Object>();
	map.put("money", 3000);
	processEngine.getTaskService().complete(taskId,map);
	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 = "145001";
	ProcessInstance singleResult = processEngine.getRuntimeService()
										.createProcessInstanceQuery()
										.processInstanceId(processInstanceId)
										.singleResult();
	if (singleResult != null) {
		System.out.println("流程执行到："+singleResult.getActivityId());
	}else{
		System.out.println("流程执行完毕");
	}
}

总结:

在排他网关当中,如果不符合设置了条件的连线,则会通过设置的默认连线继续执行流程
注意:执行默认连线还是需要设置流程变量
