***************************
APPLICATION FAILED TO START
***************************

Description:

Parameter 0 of constructor in com.fangly.upms.impl.controller.SysMenuController required a single bean, but 2 were found:
	- sysMenuServiceImpl: defined in file [D:\myProject\fangly-scafford-project\fangly-scaffold\fangly-upms\fangly-upms-impl\target\classes\com\fangly\upms\impl\service\impl\SysMenuServiceImpl.class]
	- sysMenuService: defined in file [D:\myProject\fangly-scafford-project\fangly-scaffold\fangly-upms\fangly-upms-impl\target\classes\com\fangly\upms\impl\service\SysMenuService.class]


Action:

Consider marking one of the beans as @Primary, updating the consumer to accept multiple beans, or using @Qualifier to identify the bean that should be consumed

Disconnected from the target VM, address: '127.0.0.1:64008', transport: 'socket'

Process finished with exit code 1

搭项目的时候遇到报错，觉得很奇怪，然后进行问题排查，发现是@mapperScan的扫描范围过大导致，把扫描范围改小就好了。

将其改为：

@MapperScan("com.fangly.upms.impl.mapper")

报错消失。
