一个简单的activiti请假流程的完整DEMO：

1.  创建Activiti流程引擎对象

ProcessEngineConfiguration cfg = ProcessEngineConfiguration
                    .createStandaloneProcessEngineConfiguration();
    cfg.setJdbcUrl("jdbc:mysql://localhost:3306/activiti?useSSL=false");
    cfg.setJdbcUsername("root");
    cfg.setJdbcPassword("root");
    cfg.setJdbcDriver("com.mysql.jdbc.Driver");
    ProcessEngine processEngine = cfg.buildProcessEngine();

1.  部署流程定义

RepositoryService repositoryService = processEngine.getRepositoryService();
    
    Deployment deployment = repositoryService.createDeployment()
        .addClasspathResource("Leave.bpmn20.xml")
        .deploy();
        
    String deploymentId = deployment.getId();

1.  启动流程实例

RuntimeService runtimeService = processEngine.getRuntimeService();
    ProcessInstance processInstance = runtimeService
        .startProcessInstanceByKey("leave");

1.  获取任务并完成任务

TaskService taskService = processEngine.getTaskService();
    List<Task> tasks = taskService.createTaskQuery().taskCandidateGroup("manager").list();
    
    for (Task task : tasks) {
        
      System.out.println("Task available: " + task.getName());
      taskService.claim(task.getId(), "user");
    }
    
    tasks = taskService.createTaskQuery().taskAssignee("user").list();
    for (Task task : tasks) {
        
      System.out.println("Task for user : " + task.getName());
      taskService.complete(task.getId());
    }

1.  输出流程结束时间

HistoricProcessInstance historicProcessInstance = historyService.createHistoricProcessInstanceQuery()
                  .processInstanceId(processInstance.getId())
                  .singleResult();
    System.out.println("Process instance end time: " + historicProcessInstance.getEndTime());

注意，以上仅仅是一个常规的请假流程演示，实际情况下可能更加复杂，并且需要根据实际业务进行更改。可以将上述代码放到一个main()函数中执行，也可以将其封装成一个独立的类以便于调用。
