Maven+Spring+SpringBoot+MyBatis实现单表，连表的增删改查

文末有源码连接

1.项目结构

注意。此处Biz，Dao，Controller，Model包应在Com.yang包下面 Application.java不在父目录，由于项目加载的时候@SpringBootApplication注解会去扫描当前目录以及子目录的文件，

如果其不是父目录，则无法扫描到对应的文件，然后运行项目就会出现访问Controller访问不了。因为压根就扫描不到

controller层里的文件，又谈何访问，所以就会404not found

 这个小项目有两个表factions 和member表
