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
/**
* @param processInstanceId 流程实例
* @param isAccept 0:同意 1：驳回
* @param userId 审批人
*/
@Override
public void assginLeaveWorkFlow(String processInstanceId,int isAccept,String userId) {
Map<String,Object> map = new HashMap<>();
//得到当前实例下的task
Task 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);
}
