springboot+idea+maven多模块项⽬搭建的详细过程（连接数据库进⾏测试）创建之前项⽬之前记得改⼀下 maven 提⾼下载Pom速度
记得 setting 中要改 maven 改成阿⾥云的。具体⽅法⽹上查第⼀步搭建parents 项⽬，为maven项⽬，不为springboot 项⽬记得修改groupId
第⼆步搭建多个⼦模块， honor-dao honor-manager honor-common记得创建 honor-manager 的时候要把他的gruopId 改成com.honor.manager
这⾥爆红的原因是因为我做到后⾯然后忘记截屏了，返回来做。实际我已经创建了，所以这个步骤是对的。按照这个做法，创建 honor-dao honor-manager honor-common，记得创建 honor-manager 的时候要把他的gruopId 改成com.honor.manager
第三步在 honor-manager 下分别创建 honor-manager-fc（maven） honor-manager-user（maven） honor-manager-boot (springboot，记得要使⽤springboot创建)创建时候有两个坑第⼀个是⽗级别选错。他⼀般会默认选第⼀级别，就是 honor 但是我们要继承的是 honor-manager第⼆个是路径别写错
第四步开始对各⼤ Pom 进⾏整合 dao 中⼀般需要引⼊ common ，common ⼀般不需要引其他模块，然后呢 manager 中要同时引⼊dao 和 common第⼀个是 honor ⽗级的 pom
