Activiti5工作流笔记三


组任务

直接指定办理人

流程图如下:

使用类

相关表:

act_id_group  组

act_id_membership  组员

连线

之前的流程图都是错的,只是为了演示如何快速使用,下面通过连线学习如何画一个正确的流程图

接收活动(receiveTask,即等待活动)

不需要审批的流程,例如审批后的归档操作

 例子:

package com.itheima10.activiti.receivetask;import org.activiti.engine.ProcessEngine;import org.activiti.engine.ProcessEngines;import org.junit.Test;/** * receiveTask不需要人工干预,不需要审批,直接把当前的事情做完以后,流向下一个节点即可 * @author zd * */public class ReceiveTaskTest {    @Test    public void testDeploy(){        ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();        processEngine.getRepositoryService()        .createDeployment()        .addClasspathResource("com/itheima10/activiti/receivetask/receivetask.bpmn")        .deploy();    }        @Test    /**     * act_ru_task表中不会有新的记录,因为不需要人审批此流程     * 在act_ru_execution表中可以看到当前流程实例     */    public void testStartPI(){        ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();        processEngine.getRuntimeService()        .startProcessInstanceById("receive:1:4304");    }        @Test    public void testNextNode(){        ProcessEngine processEngine = ProcessEngines.getDefaultProcessEngine();        processEngine.getRuntimeService()        /**         * 给当前的流程实例发一个信号:往下一个节点走         */        .signal("4401");    }}
