專案中，兩個模組中都放了 Mapper，如下所示

@MapperScan(basePackages ={"com.vipsoft.his.mapper","com.vipsoft.his.sdfyy.mapper"} )

為了方便，兩個合成了一個，

@MapperScan(basePackages ={"com.vipsoft.his"} )

問題來了

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

Description:

Field fromHisApi in
 
 com.vipsoft.his.web.controller.CustodyController required a single bean, but 2 were found:
  - fromHisApiImpl: defined in file [D:\Projects\80.HIS\Test\Master\vipsoft-his-sdfyy\target\classes\com\vipsoft\his\sdfyy\service\impl\FromHisApiImpl.class]
  - IFromHisApi: defined in file [D:\Projects\80.HIS\Test\Master\vipsoft-his-api\target\classes\com\vipsoft\his\api\IFromHisApi.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

解決辦法【不好】：在實現類上增加@Primary，或者在呼叫的地方加上@Qualifier("fromHisApiImpl")
