Activiti学习笔记11 — 判断节点的使用

一、 创建流程

/**
* 3、启动流程、执行任务，并查看状态
*/
@Test
public void testExcusiveGateway() {
// 获取服务对象的实例
RuntimeService runtimeService = processEngine.getRuntimeService();

String processDefinitionKey = "确定旅游地点";
// 自动执行与Key相对应的流程的最高版本
ProcessInstance processInstance = runtimeService.startProcessInstanceByKey(processDefinitionKey);

String processInstanceId = processInstance.getId();
logger.info("processInstanceId:" + processInstance.getId());

//获取当前流程下Execution对象
Execution e1 = runtimeService
.createExecutionQuery()
.processInstanceId(processInstanceId) //每个流程的唯一标识
.activityId("申请旅游经费")    //每个活动的唯一标识
.singleResult();
Assert.assertNotNull(e1);
//执行逻辑，请领导批示旅游经费
Double money =11500d;
//把金额放入变量中
runtimeService.setVariable(e1.getId(), "money", money);
logger.info("领导批示的旅游经费是: " + money);

//推动流程流转
logger.info("executionId: " + e1.getId());
runtimeService.signal(e1.getId());

if (money >= 10000d) {
Execution e2 = runtimeService
.createExecutionQuery()
.processInstanceId(processInstanceId) //每个流程的唯一标识
.activityId("国外游")    //每个活动的唯一标识
.singleResult();
Assert.assertNotNull(e2);
logger.info("由于领导指示的经费是：" + runtimeService.getVariable(e2.getId(), "money") + ",所以你可以国外游!" );

//推动流程流转
runtimeService.signal(e2.getId());
} else if ( money > 1000d && money < 10000d ) {
Execution e2 = runtimeService
.createExecutionQuery()
.processInstanceId(processInstanceId) //每个流程的唯一标识
.activityId("国内游")    //每个活动的唯一标识
.singleResult();
Assert.assertNotNull(e2);
logger.info("由于领导指示的经费是：" + runtimeService.getVariable(e2.getId(), "money") + ",所以你可以国内游!" );

//推动流程流转
runtimeService.signal(e2.getId());
} else {
Execution e2 = runtimeService
.createExecutionQuery()
