[Spring & mybatis] org.springframework.beans.factory.NoSuchBeanDefinitionException

Spring Framework을 사용하면서 다음과 같은 에러가 발생하는 경우. 당황하지 말~고, 차근차근 설정파일을 훑어보도록 하자.

 

 

servlet-context.xml 에 다음의 설정 항목이 정상적으로 추가하였는지 확인.

아래의 설정은 다른 설정보다 우선하여 설정파일의 상위에 위치하도록 한다. 보통 <annotation-driven /> 다음에 위치시킨다.

<resources mapping="/resources/**" location="/resources/" />

 

 

다음으로 mybatis 설정 파일에서 다음과 같은 식으로 basePackage의 값을 클래스들이 위치하는 상위의 package 명을 기입하도록 한다.

 

그렇지 않을 경우 @Autowired 를 사용한 클래스를 Bean에 등록하려고 시도할때 MapperScanner는 해당 클래스찾지 못하고 org.springframework.beans.factory.NoSuchBeanDefinitionException 오류를 발생시킬 것이 확실하다.

 

 <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
  <property name="basePackage" value="com.kool.test" />
 </bean>
