2.准备流程文件one-task-process.bpmn20.xml
-----------------------------------------------------------------------------------------------------------------------
3.准备SpringBoot属性文件application.properties

-----------------------------------------------------------------------------------------------------------------------
4.实体类
包名：com.springboot.demo.domain
类名：Leave
实现：
package com.springboot.demo.domain;
import lombok.Data;
import java.io.Serializable;
import java.util.Date;
/**
* @ClassName Leave
* @Description TODO
* @Author yunshuodeng
* @Date 2019-05-05 15:47
* @Version 1.0
**/
@Data
public class Leave implements Serializable {
private String userId;
private Boolean submit;
private String startDate;
private String endDate;
private float totalDay;

private String taskName;
private String approver1;
private Boolean agree1;
private String approveDesc1;
private String approver2;
private Boolean agree2;
private String approveDesc2;

}
-----------------------------------------------------------------------------------------------------------------------
5.控制器

6.启动应用，并按如下顺序进行访问
1）启动流程
访问地址：http://localhost:8082/level/v1/start?userId=10
返回结果：{"processId":"10001"}
2）填写请假单申请
访问地址：http://localhost:8082/level/v1/apply
参数列表：
{
"desc":"测试",
"startDate":"2019-05-05",
"endDate":"2019-05-09",
"totalDay":4,
"approver1":11,
"approver2":12,
"submit":true,
"processId":"10001"
}
返回结果：
{
"taskId": "10010"
}
3）查看流程中待办任务列表
访问地址：http://localhost:8082/level/v1/find?userId=11
返回结果：{"datas":[{"userId":"10","submit":true,"startDate":"2019-05-05","endDate":"2019-05-09","totalDay":4.0,"desc":"测试","taskId":"10016","taskName":"approve1","approver1":"11","agree1":null,"approveDesc1":null,"approver2":"12","agree2":null,"approveDesc2":null,"processId":null}]}
4）直接领导审批
访问地址：http://localhost:8082/level/v1/approve1
请求参数：
{
"taskId":10016,
"approveDesc1":"同意",
"agree1":true
}
返回结果：{
"taskId": "10016"
}
5）部门领导审批
查看流程中待办任务列表
访问地址：http://localhost:8082/level/v1/find?userId=12
返回结果：
{"datas":[{"userId":"10","submit":true,"startDate":"2019-05-05","endDate":"2019-05-09","totalDay":4.0,"desc":"测试","taskId":"10022","taskName":"approve2","approver1":"11","agree1":true,"approveDesc1":"同意","approver2":"12","agree2":null,"approveDesc2":null,"processId":null}]}
执行审批操作
访问地址：http://localhost:8082/level/v1/approve2
请求参数：
{
"taskId":10022,
"approveDesc2":"同意",
"agree2":true
}
返回结果：
{
"taskId": "10022"
}
