NoSuchBeanDefinitionException SessionFactory 빈을 초기화하는 방법?

나는 질문이있다. Spring과 Hibernate를 사용하여 웹 응용 프로그램을 실행하려했는데 이상한 오류가 있습니다. NoSuchBeanDefinitionException. 스택 트레이스 :

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.hibernate.SessionFactory] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
at org.springframework.beans.factory.support.DefaultListableBeanFactory.raiseNoSuchBeanDefinitionException(DefaultListableBeanFactory.java:967)
at org.springframework.beans.factory.support.DefaultListableBeanFactory.doResolveDependency(DefaultListableBeanFactory.java:837)

at org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor$AutowiredFieldElement.inject(AutowiredAnnotationBeanPostProcessor.java:486)

이유는 모르겠다. 왜냐하면 내 servlet-context.xml에서 SessionFacory bean을 선언했기 때문이다.

또한 모든 DAO 구현과 서비스 구현에 주석을 달았습니다. 어떤 아이디어?

추가됨

이것은 내 코드의 일부입니다.

@Repository
public class HibernateUserDAO implements UserDAO {
   @Autowired
   private SessionFactory sessionFactory;
   ...
}

서비스 클래스 :

@Service
public class UserServiceImpl implements UserService, UserDetailsService {
@Autowired
private UserDAO userDAO;

@Override
@Transactional
public void create(User user) throws SQLException {
    userDAO.create(user);
}

해결법

==============================

1.구성을 정리하는 것으로 시작하겠습니다.

구성을 정리하는 것으로 시작하겠습니다.

이

<context:component-scan base-package="com.example" />

이 모든 것을 포함합니다.

<context:component-scan base-package="com.example" />
<context:component-scan base-package="com.example.service" />
<context:component-scan base-package="com.example.service.impl" />
<context:component-scan base-package="com.example.dao" />
<context:component-scan base-package="com.example.dao.impl.hibernate" />
<context:component-scan base-package="com.example.web.controller" />
<context:component-scan base-package="com.example.entity" />

구성 요소 검색을 사용하고 있으므로 모든 Bean을 명시 적으로 정의 할 필요가 없습니다 (여전히 필요한 경우 구성 요소 검색을 거의 쓸모 없게 만듭니다).

다음에이 두 콩

<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />

<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" />

이미

기본적으로 당신에게 이것을 남긴다.

<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">

</bean>

구성이 불완전하지만 구성이 잘못된 위치에 있기 때문에 오류가 발생하지 않기 때문에 문제가 해결되지는 않습니다. 데이터 소스, sessionFactory, transactionManager 및 은 applicationContext.xml로 이동해야합니다. Nex에는 applicationContext.xml에도 컨트롤러를 제외한 모든 항목을 검색하는 구성 요소 검색이 포함되어야합니다.

    <context:component-scan base-package="com.example">
    <context:exclude-filter type="annotation" value="org.springframework.stereotype.Controller" />
</context:component-scan">

servlet-context.xml의 을 다음과 같이 변경하십시오.

<context:component-scan base-package="com.example" use-default-filters="false">
    <context:include-filter type="annotation" value="org.springframework.stereotype.Controller" />
</context:component-scan">

@Service 및 @Repository 빈의 중복 인스턴스화를 방지하기 위해. ContextLoaderListener와 DispatcherServlet이 같은 bean을 로딩하고 생성하고 있습니다. 좋은 예외와 다른 메모리로의 각 bean의 인스턴스가 2 개씩 있습니다.

==============================

2.때때로 Spring이 실제로 말하고자하는 것은 :

때때로 Spring이 실제로 말하고자하는 것은 :

There are multiple bean definitions...

나는이 문제가 있었다 :

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'metadataGeneratorFilter' is defined

한 번 내가 어디서 이런 XML 파일을 가지고 :

<security:custom-filter ref="metadataGeneratorFilter" before="CHANNEL_FILTER"/>

<beans:bean id="metadataGeneratorFilter"
            class="org.springframework.security.saml.metadata.  MetadataGeneratorFilter">
    <beans:constructor-arg ref="metadataGenerator"/>
</beans:bean>

==============================

@Autowired를 사용하면 컨텍스트에서 속성처럼 선언 할 필요가 없습니다. 그러나 컨텍스트에 있어야합니다. ---> NoSuchBeanDefinition -> 찾지 못했습니다.
```
<bean id="userService" class="com.example.service.impl.UserServiceImpl">
    <property name="userDAO" ref="userDAO" /> 
</bean>
```
속성 컨텍스트에서 userDAO를 제거하십시오. 자동 라우트하면 컨텍스트에서 필요하지 않습니다.

그러나 문제는이 콩에있는 것처럼 보인다.
```
<bean id="userDAO" class="com.example.dao.impl.hibernate.HibernateUserDAO" />
```
sessionFactory의 종속성을 주입 할 수는 없지만 모든 것이 올바른 것처럼 보입니다. 세션 팩토리에서 @autowired를 제거하려고하지 마십시오. hibernateUserDao의 컨텍스트에서 add 속성 참조를 가져 오거나 설정하십시오.
