二、发布流程
1 /** 2 * 2、发布一个流程 3 */ 4 @Test 5 public void testDeployProcess() { 6 RepositoryService repositoryService = processEngine.getRepositoryService(); 7 DeploymentBuilder builder = repositoryService.createDeployment(); 8 // 加载发布资源 9 builder.name("判断分支结点流程测试") // 设置流程显示别名 10 .addClasspathResource("travel.bpmn") // 设置流程规则文件 11 .addClasspathResource("travel.png"); // 设置流程规则的图片 12 // 发布流程 13 builder.deploy(); 14 }
三、运行、测试流程
1 /** 2 * 3、启动流程、执行任务，并查看状态 3 */ 4 @Test 5 public void testExcusiveGateway() { 6 // 获取服务对象的实例 7 RuntimeService runtimeService = processEngine.getRuntimeService(); 8 9 String processDefinitionKey = "确定旅游地点"; 10 // 自动执行与Key相对应的流程的最高版本 11 ProcessInstance processInstance = runtimeService.startProcessInstanceByKey(processDefinitionKey); 12 13 String processInstanceId = processInstance.getId(); 14 logger.info("processInstanceId:" + processInstance.getId()); 15 16 //获取当前流程下Execution对象 17 Execution e1 = runtimeService 18 .createExecutionQuery() 19 .processInstanceId(processInstanceId) //每个流程的唯一标识 20 .activityId("申请旅游经费") //每个活动的唯一标识 21 .singleResult(); 22 Assert.assertNotNull(e1); 23 //执行逻辑，请领导批示旅游经费 24 Double money =11500d; 25 //把金额放入变量中 26 runtimeService.setVariable(e1.getId(), "money", money); 27 logger.info("领导批示的旅游经费是: " + money); 28 29 //推动流程流转 30 logger.info("executionId: " + e1.getId()); 31 runtimeService.signal(e1.getId()); 32 33 if (money >= 10000d) { 34 Execution e2 = runtimeService 35 .createExecutionQuery() 36 .processInstanceId(processInstanceId) //每个流程的唯一标识 37 .activityId("国外游") //每个活动的唯一标识 38 .singleResult(); 39 Assert.assertNotNull(e2); 40 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!" ); 41 42 //推动流程流转 43 runtimeService.signal(e2.getId()); 44 } else if ( money > 1000d && money < 10000d ) { 45 Execution e2 = runtimeService 46 .createExecutionQuery() 47 .processInstanceId(processInstanceId) //每个流程的唯一标识 48 .activityId("国内游") //每个活动的唯一标识 49 .singleResult(); 50 Assert.assertNotNull(e2); 51 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!" ); 52 53 //推动流程流转 54 runtimeService.signal(e2.getId()); 55 } else { 56 Execution e2 = runtimeService 57 .createExecutionQuery() 58 .processInstanceId(processInstanceId) //每个流程的唯一标识 59 .activityId("省内游") //每个活动的唯一标识 60 .singleResult(); 61 Assert.assertNotNull(e2); 62 logger.info("由于领导指示的经费是：" + runtimeService.getVariable(e2.getId(), "money") + ",所以你可以省内游!" ); 63 64 //推动流程流转 65 runtimeService.signal(e2.getId()); 66 } 67 68 //检查结束状态 69 ProcessInstance pInstance = runtimeService 70 .createProcessInstanceQuery() 71 .processInstanceId(processInstanceId) 72 .singleResult(); 73 Assert.assertNull(pInstance); 74 logger.info("判断分支结点流程成功执行！"); 75 }
四、运行结果

[INFO][2015-12-02 14:39:58,641][com.mcs.activiti.test.TestExclusiveGateway]领导批示的旅游经费是: 11500.0
[INFO][2015-12-02 14:39:58,642][com.mcs.activiti.test.TestExclusiveGateway]executionId: 170001
[INFO][2015-12-02 14:39:58,816][com.mcs.activiti.test.TestExclusiveGateway]由于领导指示的经费是：11500.0,所以你可以国外游!
