目标
创建一个大众流程（请假流程）并且可以跑起来。
需要的预备知识
camunda数据库表的基本认识 表介绍链接
流程图的制作
- 下载camunda的绘图工具 流程图工具地址
-
绘制请假流程图（XML去掉了布局元素）

流程的部署
- 复制如上的流程图xml信息到classpath目录下
- 部署流程
/**
* 部署bpmn。xml资源文件
*/
public void bpmnImport() {
Deployment deploy = repositoryService
.createDeployment()
// .name("请假申请")
.addClasspathResource("diagram_1.bpmn")
.deploy();
log.info(deploy.getName());
log.info(deploy.getId());
}
运行后如下表会一些基本信息
运行后结果-未设置name.png
运行后结果-设置name.png
流程的运行
/**
* 开始一个流程实例
*/
public void startBpm(String proInsId) {
ProcessInstance processInstance = runtimeService.startProcessInstanceByKey(proInsId);
String id = processInstance.getId();
log.info(id);
}

流程的审批
/**
* 完成一个任务 不带参数
* @param taskId
*/
public void comTask(String taskId) {
taskService.complete(taskId);
}
运行结果
/**
* 完成一个任务， 并且可以设置变量参数
* @param taskId
*/
public void comTask(String taskId, Map map) {
taskService.complete(taskId, map);
}
带参数测试结果
结束语
至此一个简单固定的流程就可以成功完成！

}
/**

*/
@Test

resService.comTask("5cbe9b2b-0a0d-11eb-9439-c81f66132ec7", map);
