SpringBoot集成MybatisPlus, Redis,hikari ,swagger2 带配置写法
工具idea ， 模块化项目搭建
1:先创建一个project 删掉其中的src等多余目录 ,留一个 pom.xml
pom.xml 如下:
4.0.0
com.text
demo
1.0-SNAPSHOT
org.springframework.boot
spring-boot-starter-parent
2.0.4.RELEASE
2:右键项目，创建一个module 项目 【demoAdmin】 , 注:创建项目后,外层pom会多个 modules
此模块 pom.xml 如下:
demo
com.text
1.0-SNAPSHOT
4.0.0
demoAdmin
org.springframework.boot
spring-boot-starter-web
org.projectlombok
lombok
true
com.baomidou

3-2 common 包结构class如下图:
类文件解释:
ApiCommonController: 自定义父类 ，封装了自定义异常监控
