前言

最近在做springboot 一直踩坑

问题描述

在整合mybatis时只是生成了两个insert()函数，并且提示
[WARNING] Cannot obtain primary key information from the database, generated objects may be incomplete

解决方法

在jdbc连接url上加nullCatalogMeansCurrent=true

url=jdbc:mysql://localhost:3306/helloword?useUnicode=true&characterEncoding=utf-8&nullCatalogMeansCurrent=true

亲测已经解决
