JBPM4基础篇-IdentityService实现组织机构

使用IdentityService实现用户和用户组之间的关系对应。

     public TaskTest() {
         processEngine = Configuration.getProcessEngine();
         IdentityService identityService = processEngine.getIdentityService(); // 身份验证
         identityService.createGroup("dev"); // 创建一个组，需要在XML中指定一个task的type为candidate-groups，expression为"dev"
         identityService.createUser("user1", "user1", "user1"); // 创建用户1

     }

     public void test() {
         RepositoryService repositoryService = processEngine.getRepositoryService();
         TaskService taskService = processEngine.getTaskService();
         ExecutionService executionService = processEngine.getExecutionService();

         ProcessInstance processInstance = executionService.startProcessInstanceByKey("task"); // 开始执行一个流程
         assertEquals(1, taskService.findGroupTasks("user1").size()); // 判断某一个用户的任务列表中任务的个数
         assertEquals(1, taskService.findGroupTasks("user2").size());

         List taskList = taskService.findGroupTasks("user1"); // 获取user1的任务列表
         Task task = taskList.get(0);
         taskService.takeTask(task.getId(), "user1"); // 执行任务
         taskService.completeTask(task.getId()); // 完成任务
     }
