[해결] "this.custRepository" is null

문제 상황

CardController 에서 CustomerRepository를 선언하여 getOne을 사용했는데, 에러

 

Whitelabel Error Page

This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Internal Server Error, status=500).

Cannot invoke "com.spring.web.repository.CustomerRepository.getOne(Object)" because "this.custRepository" is null

​

해결:

CardContorller 에서 CustomerRepository를 선언하기 이해 정의할 때,

private CustomerRepository custRepository;

위에 @Autowired 를 붙여줌

​

@Autowired

private CustomerRepository custRepository;
