springCloud集成activiti5.22.0流程引擎

帮助别人的同时更是丰富自己的良机。

一.Spring boot2.x与Activiti 5.22.0整合

1.POM文件中添加依赖

<dependency><groupId>org.activiti</groupId><artifactId>activiti-spring-boot-starter-basic</artifactId><version>5.22.0</version><exclusions><!-- 排除activiti的mybatis，避免和外面的mybatis-plus冲突 --><exclusion><artifactId>mybatis</artifactId><groupId>org.mybatis</groupId></exclusion></exclusions>
</dependency>

二.制作bpmn流程文件

创建bpmn文件

右键该文件夹New–>BPMN File 创建名为leave_flow的流程文件

文件名"xxx.bpmn" 更改为 “xxx.bpmn.xml”
注: 因为activiti的默认流程图格式是bpmn, 但是idea必须xml格式才能生成图片, 所以改为这样, 后面部署流程的时候才可以部署上去, 否则是存不进数据库.

三.流程演示

分支审批

 @Overridepublic void assginLeaveWorkFlow(String processInstanceId,int isAccept,String userId) {Map<String,Object> map = new HashMap<>();//得到当前实例下的taskTask task = taskService.createTaskQuery().processInstanceId(processInstanceId).singleResult();taskService.addComment(task.getId(), processInstanceId, "审核人是否同意该请假流程");if(isAccept == 0){map.put("accept","同意");task.setAssignee(userId);map.put("userId", userId);}else{map.put("accept","驳回");//审核驳回后task.setAssignee("发起人");map.put("auditor","发起人");}task.setDescription("请假的描述信息");//执行当前这个工作流任务taskService.saveTask(task);taskService.complete(task.getId(), map);}
