인프런 커뮤니티 질문&답변

안녕하세요 강의잘보고있습니다.:)

강의내용을 그대로 따라하고 있는데, 강의에서는 안나는 오류가 해결되지않아서 질문드립니다.ㅠㅠㅠ

1. CoreApplication을 빌드시,

Parameter 1 of constructor in hello.core.Order.OrderServiceImpl required a single bean, but 2 were found:

- rateDiscountPolicy: defined in file [C:\core\core\out\production\classes\hello\core\discount\RateDiscountPolicy.class]

- DiscountPolicy: defined by method 'DiscountPolicy' in class path resource [hello/core/AppConfig.class]

위와 같은 오류가 납니다

2. Run All test 시,

CoreApplicationTest의 contextLoads()에서,

와 같이 에러가 납니다.

두가지 오류가 한군데에서 나는것 같은데, 어디가 문제인지잘 모르겠습니다,,
