java - 错误创建名为“ModelAccess”的 bean 自动装配依赖注入失败；无法自动装配字段

问题描述

这是我的项目的结构：

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 包中连接到 oracle 数据库。它包含一些类，问题在于 ModelAccess 类：

@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：

创建名为“ModelAccess”的 bean 时出错：注入自动装配的依赖项失败；嵌套异常是 org.springframework.beans.factory.BeanCreationException：无法自动装配字段：com.company.myproject.impl.ProjectRepository com.company.myProject.impl.ModelAccess.jpaRepository；嵌套异常是 org.springframework.beans.factory.NoSuchBeanDefinitionException：没有为依赖找到 [com.company.myproject.impl.ProjectRepository] 类型的合格 bean：预计至少有 1 个 bean 有资格作为此依赖的自动装配候选者。依赖注解：{@org.springframework.beans.factory.annotation.Autowired(required=true)}

==================================================== ==========================这是我的pom文件的一部分：
