[Error] Field repository in required a bean of type 'xxx' that could not be found.

# Error

Intellij에서 @Autowired를 통해서 CrudRpository를 상속받는 인터페이스를 사용할 때 아래와 같은 error가 발생한다.

Field repository in com.example.SpringDataJDBCSample.SpringDataJdbcSampleApplication required a bean of type 'xxx' that could not be found. 

 

# Solution

@EnableJdbcRespositories을 통해 JDBC Repository 를 활성화 할 수 있다.

@SpringBootApplication
@EnableJdbcRepositories(basePackages = { "path of target package ex) com.demo" })
public class SpringDataJdbcSampleApplication {
	public static void main(String[] args) {
		...
	}

	@Autowired
	Sample repository;
}
