Activiti学习笔记7 — ReceiveTask机器自动任务的使用

一、 创建流程规则,如下图

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("机器自动执行流程测试") // 设置流程显示别名
10                 .addClasspathResource("receiveTask.bpmn") // 设置流程规则文件
11                 .addClasspathResource("receiveTask.png"); // 设置流程规则的图片
12         // 发布流程
13         builder.deploy();
14     }

三、启动流程,并自动执行任务

 1 /**
 2      * 3、启动流程,并自动执行任务
 3      */
 4     @Test
 5     public void testStartProcess() {
 6         // 获取服务对象的实例
 7         RuntimeService runtimeService = processEngine.getRuntimeService();
 8 
 9         String processDefinitionKey = "receiveTask";
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         
15         logger.info("Id:" + processInstance.getId());
16         
17         //获取当前流程下Execution对象
18         Execution e1 = runtimeService
19                                             .createExecutionQuery()
20                                             .processInstanceId(processInstanceId) //每个流程的唯一标识
21                                             .activityId("汇总当天销售额")    //每个活动的唯一标识
22                                             .singleResult();
23         Assert.assertNotNull(e1);
24         //自动逻辑的绑定-汇总当天销售额,进行一堆逻辑后,得到金额money
25         Double money = 888888.88d;
26         //把金额放入变量中
27         runtimeService.setVariable(e1.getId(), "销售额", money);
28         logger.info("汇总后当天的销售额是: " +  money);
29         
30         //推动流程流转
31         runtimeService.signal(e1.getId());
32         
33         //判断当前流程,是否仪在一个节点ID是“发短信给老板”的活动节点
34         Execution e2 = runtimeService
35                 .createExecutionQuery()
36                 .processInstanceId(processInstanceId) //每个流程的唯一标识
37                 .activityId("发短信给老板")    //每个活动的唯一标识
38                 .singleResult();
39         Assert.assertNotNull(e2);
40         Double m = (Double) runtimeService.getVariable(e2.getId(), "销售额");
41         logger.info("老板,今天的销售额是:" +m);
42         
43         //推动流程流转
44         runtimeService.signal(e2.getId());
45         
46         //检查结束状态
47         ProcessInstance pInstance = runtimeService
48                                                         .createProcessInstanceQuery()
49                                                         .processInstanceId(processInstanceId)
50                                                         .singleResult();
51         Assert.assertNull(pInstance);
52         logger.info("机器自动任务流程成功执行!");        
53     }

四、执行后的结果如下:

[INFO][2015-12-01 17:34:46,411][com.mcs.activiti.test.TestReceiveTask]Id:60001
[INFO][2015-12-01 17:34:46,570][com.mcs.activiti.test.TestReceiveTask]汇总后当天的销售额是: 888888.88
[INFO][2015-12-01 17:34:46,625][com.mcs.activiti.test.TestReceiveTask]老板,今天的销售额是:888888.88
[INFO][2015-12-01 17:34:46,783][com.mcs.activiti.test.TestReceiveTask]机器自动任务流程成功执行!
