Spring 4.2.6 NoSuchBeanDefinitionException

Question

我正在努力找到发生此错误的原因。

org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [de.my.package.web.repository.ContactFormRepository] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

如标题中所述，我在带有Java 1.7的Tomcat 7上使用Spring 4.2.6。

以下是我已经尝试解决的更多代码。

这是ContactFormRepository：

@Repository
public interface ContactFormRepository extends JpaRepository<FooterContactForm, Long> {
   List<FooterContactForm> findByCountryName(String countryName);
}

我尝试使用CrudRepository来换取JpaRepository（我可能只需要Crud）。 我删除了@Repository，并将@Repository更改为@Component。两者都没用。

存储库用于此类：

@Service
public class SaveDataService {
public static final Class<?> LOGGER = SaveDataService.class;

  @Autowired
  private ContactFormRepository contactFormRepository;

  @Autowired
  private MailService mailService;

  public void saveDataContact(FooterContactForm form, String content){
      contactFormRepository.save(form);
  }

}

在我的app-config.xml中，我有以下几行，我认为应该足够了。

编辑2：添加了完整的web.xml和完整的app-config.xml

Answer 1

我可能错了，但是你的web.xml中的这个声明

<servlet>
    <servlet-name>DispatcherServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/app-config.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

告诉它只限于DispatcherServlet。可以尝试在项目中创建另一个applicationContext.xml文件，例如/META-INF/spring/applicationContext.xml，在那里移动模型，存储库和服务层相关的bean。然后将以下内容添加到web.xml

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath*:META-INF/spring/applicationContext.xml</param-value>
</context-param>

我试图将此作为评论发布，但字符有限。
