三、报错原因
-
报错原因：Controller层方法的请求路径冲突（@GetMapping(’/’)），导致项目启动失败，关键错误信息：public
com.inspur.vista.ylt.common.entity.R
com.inspur.vista.ylt.conver.api.controller.HomeController.getDeptDetailByDeptId(int)
to {[/getOrgDetail],methods=[GET]}: There is already ‘/home’ bean
method -
Ctrl+c和Ctrl+v的后果：
四、解决办法
- 修改重复的接口请求路径就OK
