Question

这是我项目的结构：

scr / main / java / com / company / configuration

scr / main / java / com / company / controller

scr / main / java / com / company / myProject

scr / main / java / com / company / exception

在配置中，我有3个类：ProjectInitializer，ProjectConfiguration和ProjectContextListener。

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = {"com.company"})
 @EnableJpaRepositories("com.company")
public class ProjectConfiguration {

}

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

public class ProjectInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {

    @Override
    protected Class<?>[] getRootConfigClasses() {
        return new Class[] { ProjectConfiguration.class };
    }

    @Override
    protected Class<?>[] getServletConfigClasses() {
        return null;
    }

    @Override
    protected String[] getServletMappings() {
        return new String[] { "/" };
    }

    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {
        super.onStartup(servletContext);
        servletContext.addListener(new ProjectContextListener());

    }
}

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

公共类ProjectContextListener实现ServletContextListener {

public void contextInitialized(ServletContextEvent servletContextEvent) {
    Security.addProvider(new BouncyCastleProvider());
    Security.addProvider(new FlexiCoreProvider());
    Security.addProvider(new FlexiECProvider());
    javax.net.ssl.HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier() {
        public boolean verify(String s, SSLSession sslSession) {
            return true;
        }
    });
}

public void contextDestroyed(ServletContextEvent servletContextEvent) {
    System.out.println("Shutting down!");
}

}

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

我想在myproject包中建立到oracle数据库的连接。它包含一些类，问题出在ModelAccess类上：

@Service
public class ModelAccess {
    @Autowired
    ProjectRepository jpaRepository;
    protected JpaRepository<ProjectEnt, Long> getJpaRepository() {
        return jpaRepository;
    }
}

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

@Transactional
public interface ProjectRepository extends
        JpaRepository<ProfileEnt, Long>,IProjectRepository{


}

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

@Repository
public interface IProjectRepository extends IGenericRepository<ProfileEnt> {
}

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

这是我在tomcat中部署项目时的堆栈跟踪：

创建名称为'ModelAccess'的bean时出错：自动连接的依赖项注入失败；嵌套的异常是org.springframework.beans.factory.BeanCreationException：无法自动装配字段： com.company.myproject.impl.ProjectRepository com.company.myProject.impl.ModelAccess.jpaRepository; 嵌套的异常是org.springframework.beans.factory.NoSuchBeanDefinitionException：找不到依赖项类型为[com.company.myproject.impl.ProjectRepository]的合格Bean：期望至少有1个bean符合此依赖项的自动装配条件。依赖注释： {@ org.springframework.beans.factory.annotation.Autowired（required = true）}

Answer 1

IProjectRepository不是JpaRepository的问题。而且，看起来您不需要它。要解决此问题，只需删除IProjectRepository并改用ProjectRepository。

创建名称为'ModelAccess'的bean时出错注入自动绑定的依赖项失败；无法自动连线栏位
