springboot、mybatisplus框架整合搭建
目录结构
- 通过https://start.spring.io创建spingboot项目并导入idea
- maven添加mybatisplus、spring、mysql依赖

#MybatisPlus配置
mybatis-plus:

type-aliases-package: com.love.entity
type-aliases-super-type: java.lang.Object
server:
port: 8081
##数据库url
spring:
datasource:
url: jdbc:mysql://127.0.0.1:3306/****?characterEncoding=utf8&useSSL=false
username: ***
password: ***
driver-class-name: com.mysql.cj.jdbc.Driver
