Activiti目录（三）部署流程、发起流程

目录

Activiti（一）入门了解

Activiti（二）整合

Activiti零零碎碎的坑

一、BPMN流程

内容讲解：
applyState：0学生发起请假 1老师审核通过 2老师领导审核通过 3院长审核通过结束 4请假驳回 6学生重新申请
applyExamine：驳回后学生重新申请到谁
Gareway:必须要满足一个条件不如会报错

二、部署流程

 /** * 部署流程 * TODO 1：获取配置对象 * TODO 2：创建核心引擎 * TODO 3：获取仓库服务 * TODO 4：部署流程（指向BPMN文件、BPMN图地址） * @author hjj */
    public Result deploymentProcess() {
    
        // 部署
        Deployment deployment = repositoryService // 获取部署相关Service
                .createDeployment() // 创建部署
                .key("struApplyProcess") //设置部署流程键值
                .addClasspathResource("bpmn/struApply.bpmn20.xml") //添加bpmn文件
// .addClasspathResource("bpmn/struApply.png") //添加png文件
                .name("学生请假流程") //设置流程名称
                .deploy(); // 部署
       return Result.success("流程部署ID:"+deployment.getId() + " - " + "流程部署Name:"+deployment.getName()+ " - " + "流程部署KEY:"+deployment.getKey());

三、发起流程

/** * 启动一个流程 * TODO 1：查询用户 * TODO 2：启动申请流程设置流程实例ID及审核人员 * TODO 3：根据流程实例ID获取流程实例申请任务 * TODO 4：设置申请任务执行人 * TODO 5：发起申请任务 * TODO 6：根据流程实例ID关联业务信息并添加业务信息(一对一) * TODO 7：返回申请是否成功状态 * @param apply 申请记录信息 * @return * @author hjj */
