vue下基于elementui自定义表单-后端篇

自定义表单目前数据表单设计是基于数据量不大的信息单据场景，因为不考虑数据量带来的影响。

数据表有: 1.表单模版表，2.表单实例表，3.表单实例项明细表，4表单审批设计绑定表

以FormJson存储设计好的表单JSON信息，创建实例时冗余当前的模版JSON，记录表单数据Json，便于在重新打开单据时能动态组装页面与加载数据。

实例明细表用来纵向动态存储表单内容项，便于有统计与分析需求的时候使用。

表单模版关联审批，发起表单时自动绑定审批流程，流程结束变更表单审批状态。

附件处理：统一附件上传入口，上传后返回附件地址与表单内容一起保存。

所有表单数据都存在表单实例中，可按实际情况进行分表处理。

 数据JSON:

 {"applicant":"刘仪","department":"技术管理","startDate":"2022-11-01","startTime":"08:30","endTime":"12:30","meetRoom":"NO.4","title":"技術連絡","fd_1660786142984":"","fd_1661955389858":"","fd_1661955304719":"","id":4099124702193258500,"docNum":"HY20221008"}

 前端通过表单模版数据动态加载组装表单组件，然后通过数据JSON填入表单form内容。
