Activiti的画图插件的安装

工作流的流程步骤
（1）画出业务流程图
（2）部署流程
（3）启动流程实例
（4）查询当前办理人的个人任务
（5）完成任务
业务流程图（学生请假）

创建Activiti的表，Activiti跟Spring结合，在项目初始化就可以创建了
部署流程的两种方式（）

  /**
       * 部署流程定义使用ClassPath方式（添加）
       * 表的变化：
       * act_re_deployment  流程部署表
       * act_re_procdef  流程定义表
       * act_ge_bytearray  资源文件表
       * act_ge_property   系统配置表
       * */

       @Test
       public void TestflowWithClassPath(){
           private ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();//获取流程引擎对象（Activiti的核心对象）

            Deployment deployment =  processEngine.getRepositoryService()  //根据调用流程引擎对象的RepositoryService方法获得 deployment 对象
           .createDeployment()
           .addClasspathResource("diragrams/studentLeaveProcess.bpmn")
           .addClasspathResource("diragrams/studentLeaveProcess.png")
           .name("学生请假流程")
           .deploy();
            //查询流程部署表（以下数据信息）
            System.out.println("流程部署id:"+deployment.getId());
            System.out.println("流程部署名称:"+deployment.getName());
        }

   /**
    * 部署流程定义使用Zip方式（添加）
    *
    * 
    * 
    * */

   @Test
   public void TestFlowWithZip(){
       InputStream inputStream = this.getClass()         //获取当前类对象
           .getClassLoader()  //获取类加载器
           .getResourceAsStream("diragrams/HelloWord.zip");  //获取指定文件资源
       ZipInputStream zipInputStream = new ZipInputStream(inputStream);
       Deployment deployment =  processEngine.getRepositoryService()
       .createDeployment().addZipInputStream(zipInputStream)
       .name("lmy1")
       .deploy();
       System.out.println("流程部署id:"+deployment.getId());
       System.out.println("流程部署名称:"+deployment.getName());

   }

启动流程

 /**
    * 启动流程实例
    * 表的变化：
    * act_ru_excutioon  执行对象表
    * act_ru_identitylink 身份联系表
    * act_ru_task        任务表
    * act_hi_actinst  活动节点历史表
    * act_hi_identitylink  身份联系历史表
    * act_hi_procinst      流程实例历史表
    * act_hi_taskinst    历史任务表
    * */
   @Test
   public void Start(){
              // RuntimeService：在Activiti中，每当一个流程定义被启动一次之后，都会生成一个相应的流程对象实例。RuntimeService提供了启动流程、查询流程实例、设置获取流程实例变量等功能。此外它还提供了对流程部署，流程定义和流程实例的存取服务。
      ProcessInstance pi = processEngine.getRuntimeService()  //使用流程定义的key启动流程
       .startProcessInstanceByKey("myFirstProcess");
       System.out.println("流程实例id:"+pi.getId());
       System.out.println("流程定义id:"+pi.getProcessDefinitionId());
   }

查询当前人的任务

   @Test
   public void Tasklmy(){
// TaskService: 在Activiti中业务流程定义中的每一个执行节点被称为一个Task，对流程中的数据存取，状态变更等操作均需要在Task中完成。TaskService提供了对用户Task 和Form相关的操作。它提供了运行时任务查询、领取、完成、删除以及变量设置等功能。
       List<Task> taskList =  processEngine.getTaskService()
       .createTaskQuery()
       .taskAssignee("lmy")
       .list();
       for (Task task:taskList) {
           System.out.println("任务id"+task.getId());
           System.out.println("任务name"+task.getName());
           System.out.println("任务创建时间"+task.getCreateTime());
           System.out.println("任务委派人"+task.getAssignee());
           System.out.println("流程实例id"+task.getProcessInstanceId());
       }
   }

完成任务

 /**
    * 结束流程
    * 表的变化：
    * 带有re_的数据清空
    * 历史表的（hi_）数据修改或者添加
    * 
    * 
    * */
   @Test
   public void completeTask(){
       processEngine.getTaskService()
       .complete("25004");//任务的id 
   }
