接着 BPMN 2.0 - Activiti, 我们以请假的工作流为例, 开始测试流程变量的设置于获取.

发布工作流程

/**
   * 发布一个流程
   *
   * @throws  IOException  exception
   */
  @Test public void test2DeployTask() throws IOException {
    myService.createDynamicWorkflow(WORKFLOW_PROCESS_DEPLOYMENT_NAME, BPMNResourceType.BPMN_20,
      bpmnXML);

    // search workflow process
    List<Deployment> deployments = myService.findDeploymentByDeploymentName(WORKFLOW_PROCESS_DEPLOYMENT_NAME);
    Assert.assertEquals(1, deployments.size());

    deployments = myService.findDeploymentByProcessDefinitionKey(WORKFLOW_PROCESS_DEFINITION_KEY);
    Assert.assertEquals(1, deployments.size());

    // get last deployment
    Deployment deployment = deployments.get(0);

    List<String> resourceNames = myService.findDeploymentResourceNamesByDeploymentId(deployment.getId());
    printResources(deployment.getId(), resourceNames);
  }

启动工作流程, 创建工作流实例:

String          assignee        = "Tom";
ProcessInstance processInstance = myService.startProcess(WORKFLOW_PROCESS_DEFINITION_KEY, assignee);

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

获取分配给当前用户的任务:

// 获取TaskService服务对象的实例
List<Task> tasks = myService.getTasks(assignee);
Assert.assertEquals(1, tasks.size());

Task task = tasks.get(0);
logger.info("taskName:" + task.getName());
logger.info("taskAssignee:" + task.getAssignee());
Assert.assertEquals("提交申请", task.getName());

设置流程变量

int    days   = 7;
Date   date   = new Date();
String reason = "回家过年";

// 1.设置流程变量，使用基本数据类型
myService.setTaskVariable(task.getId(), "请假天数", days); // 与任务ID邦德
myService.setTaskVariable(task.getId(), "请假日期", date);
myService.setTaskVariable(task.getId(), "请假原因", reason);

获取流程变量

Map<String, Object> taskVariables = myService.getTaskVariables(task.getId());
Assert.assertEquals(taskVariables.get("请假天数"), days);
Assert.assertEquals(taskVariables.get("请假日期"), date);
Assert.assertEquals(taskVariables.get("请假原因"), reason);

这两个步骤的可以给流程设置一些
