Activiti学习笔记9 — UserTask共有任务的使用

1、创建流程引擎对象

private ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();

2、发布一个流程

    /**
     * 2、发布一个流程
     */
    @Test
    public void  testDeployProcess() {
        RepositoryService repositoryService = processEngine.getRepositoryService();
        DeploymentBuilder builder = repositoryService.createDeployment();
        // 加载发布资源
        builder.name("UserTask共有任务流程测试") // 设置流程显示别名
                .addClasspathResource("userPublicTask.bpmn") // 设置流程规则文件
                .addClasspathResource("userPublicTask.png"); // 设置流程规则的图片
        // 发布流程
        builder.deploy();
    }

3、启动流程、执行任务，并查看状态

    /**
     * 3、启动流程、执行任务，并查看状态
     */
    @Test
    public void testUserTask() {        
        //1.获取RuntimeService服务对象的实例
        RuntimeService runtimeService = processEngine.getRuntimeService();
        String processDefinitionKey = "userPublicTask";
        //2.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());
        
        //3.获取TaskService服务对象的实例
        TaskService taskService = processEngine.getTaskService();
        //4.私有任务执行
        //4.1、获取私有任务
        String assignee = "取号";
        List<Task> tasks = taskService.createTaskQuery().taskAssignee(assignee).list();
        Assert.assertEquals(1, tasks.size());
        Task task = tasks.get(0);        
        logger.info("taskName:" + task.getName());
        Assert.assertEquals("取号",task.getName());
        
        //4.2完成任务
        taskService.complete(task.getId());        
        
        //4.3检查流程状态
        ProcessInstance p1 = runtimeService.createProcessInstanceQuery().processInstanceId(processInstanceId).singleResult();
        Assert.assertNotNull(p1);
        logger.info("取号私有任务流程成功执行！");        
        
        
        //5、共有任务执行
        //5.1、确认柜员1私有任务列表中没有相关任务
        String assignee1 = "柜员1";
        List<Task> tasks1 = taskService.createTaskQuery().taskAssignee(assignee1).list();
        Assert.assertEquals(0, tasks1.size());
        logger.info("柜员1的私有任务数量：" + tasks1.size());
        
        //5.2、确认柜员2私有任务列表中没有相关任务
        String assignee2 = "柜员2";
        List<Task> tasks2 = taskService.createTaskQuery().taskAssignee(assignee2).list();
        Assert.assertEquals(0, tasks2.size());
        logger.info("柜员2的私有任务数量：" + tasks1.size());
        
        //5.3、获取共有任务列表
        //5.3.1、获取柜员1共有任务列表
        String candidateUser1 = "柜员1";
        List<Task> tasks3 = taskService.createTaskQuery().taskCandidateUser(candidateUser1).orderByTaskCreateTime().desc().list();        
        Task task3 = tasks3.get(0);
        logger.info("柜员1的共有任务数量：" + tasks3.size() + " ID: " + task3.getId() + " Name: " + task3.getName());
        
        //5.3.2、获取柜员2共有任务列表
        String candidateUser2 = "柜员2";
        List<Task> tasks4 = taskService.createTaskQuery().taskCandidateUser(candidateUser2).orderByTaskCreateTime().desc().list();        
        Task task4 = tasks4.get(0);
        logger.info("柜员2的共有任务数量：" + tasks4.size() + " ID: " + task4.getId() + " Name: " + task4.getName());
        
        //5.4、柜员2受理任务        
        taskService.claim(task4.getId(), "柜员2"); 
        logger.info("柜员2受理任务!");
        
        //5.5、查看柜员1和柜员2的私有与共有任务数量
        String assignee3 = "柜员1";
        List<Task> tasks5 = taskService.createTaskQuery().taskAssignee(assignee3).list();
        logger.info("柜员1的私有任务数量：" + tasks5.size());
        
        String assignee4 = "柜员2";
        List<Task> tasks6 = taskService.createTaskQuery().taskAssignee(assignee4).list();
        logger.info("柜员2的私有任务数量：" + tasks6.size());
        
        String candidateUser3 = "柜员1";
        List<Task> tasks7 = taskService.createTaskQuery().taskCandidateUser(candidateUser3).orderByTaskCreateTime().desc().list();        
        logger.info("柜员1的共有任务数量：" + tasks7.size());
        
        String candidateUser4 = "柜员2";
        List<Task> tasks8 = taskService.createTaskQuery().taskCandidateUser(candidateUser4).orderByTaskCreateTime().desc().list();        
        logger.info("柜员2的共有任务数量：" + tasks8.size());
        
        //5.6、柜员2完成任务
        taskService.complete(task4.getId());
        
        //5.6检查结束状态
        ProcessInstance p2 = runtimeService.createProcessInstanceQuery().processInstanceId(processInstanceId).singleResult();
        Assert.assertNull(p2);
        logger.info("UserTask共有任务流程成功执行！");        
    }
