org.springframework.beans.factory.UnsatisfiedDependencyException

Question

MVC06 소스 톰캣 실행 시 아래 오류가 발생합니다.   ERROR: org.springframework.web.servlet.DispatcherServlet - Context initialization failed org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'memberController': Unsatisfied dependency expressed through field 'memberUserDetailsService'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type ' kr.ody.apps.security .MemberUserDetailsService' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)} at org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor$AutowiredFieldElement.inject( AutowiredAnnotationBeanPostProcessor.java:586 ) at org.springframework.beans.factory.annotation.InjectionMetadata.inject( InjectionMetadata.java:91 ) at org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor.postProcessPropertyValues( AutowiredAnnotationBeanPostProcessor.java:372 ) at org.springframework.beans.factory.support .AbstractAutowireCapableBeanFactory.populateBean( AbstractAutowireCapableBeanFactory.java:1344 ) at org.springframework.beans.factory.support .AbstractAutowireCapableBeanFactory.doCreateBean( AbstractAutowireCapableBeanFactory.java:582 ) at org.springframework.beans.factory.support .AbstractAutowireCapableBeanFactory.createBean( AbstractAutowireCapableBeanFactory.java:502 )   구글링으로 파악이 안되네요. 원인이 무엇일까요?

자답   @Controller public class MemberController { @Autowired MemberMapper memberMapper; @Autowired(required=false) // required를 false로 하여 주입 안받아도 예외처리 하지 않도록 함. MemberUserDetailsService memberUserDetailsService;
