在过去的4-5天里，我一直试图让我的头围绕spring & hibernate，我觉得我差不多他们......我真的很困惑为什么我收到这些auto-wire错误。
我试图创建一个rest api，所以我已经使用了 mvc 模式。
有没有人知道我为什么会收到这些错误？我在下面提供了我的设置和堆栈跟踪。
@Controller
@RequestMapping("/")
@Component
public class userController {
@Autowired
userService userService;
@RequestMapping(value = { "/", "/list" }, method = RequestMethod.GET)
public String listUsers(ModelMap model) {
List<user> users = userService.findAll();
model.addAttribute("users", users);
return "userslist";
}
}
import hibernate.dao.userDAO;
@Service("userService")
@Transactional
public class userServiceImpl implements userService {
@Autowired
userDAO dao;
public List<user> findAll() {
return dao.list();
}
public user findById() {
return null;
}
public void saveuser(user p) { }
public void updateuser(user p) {}
}
public interface userService {
List<user> findAll();
user findById();
void saveuser(user p);
void updateuser(user p);
}
@Repository("userDAO")
public class userDAOImpl extends AbstractDao<Integer, user> implements userDAO {
public List<user> list() {
Criteria criteria = createEntityCriteria().addOrder(Order.asc("firstName"));
criteria.setResultTransformer(Criteria.DISTINCT_ROOT_ENTITY);//To avoid duplicates.
List<user> users = (List<user>) criteria.list();
return users;
}
public void save(user ps) {
persist(ps);
}
}
public abstract class AbstractDao<PK extends Serializable, T> {
private final Class<T> persistentClass;
@SuppressWarnings("unchecked")
public AbstractDao(){
this.persistentClass =(Class<T>) ((ParameterizedType) this.getClass().getGenericSuperclass
()).getActualTypeArguments()[1];
}
@Autowired
private SessionFactory sessionFactory;
protected Session getSession(){
return sessionFactory.getCurrentSession();
}
@SuppressWarnings("unchecked")

我尝试删除@Repository("userDAO")中的标签并将其设为@Repository。如其中一个答案所示。
这并没有改变任何事情。
这是我的主要课程：
import org.hibernate.HibernateException;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.hibernate.service.ServiceRegistry;
import org.hibernate.service.ServiceRegistryBuilder;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class Main {
private static final SessionFactory ourSessionFactory;
private static final ServiceRegistry serviceRegistry;
static {
try {
Configuration configuration = new Configuration();
configuration.configure();
serviceRegistry = new ServiceRegistryBuilder().applySettings(configuration.getProperties()).buildServiceRegistry();
ourSessionFactory = configuration.buildSessionFactory(serviceRegistry);
} catch (Throwable ex) {
throw new ExceptionInInitializerError(ex);
}
}
public static Session getSession() throws HibernateException {
return ourSessionFactory.openSession();
}
public static void main(final String[] args) throws Exception {
SpringApplication.run(Main.class, args);
}
}
在尝试了m.deinum的解决方案后，我得到了以下堆栈跟踪...删除daoImpl和abstractImpl是一个好主意。但是我仍然不断创建名为 X 的创建bean的错误：注册自动连接的依赖失败例外...
在调整我的代码以适应以下答案后的堆栈跟踪：

答案 0 :(得分：1)
对于初学者来说，目前你的applicationContext.xml几乎没用。如果你要删除它，重新启动，你仍然会得到相同的异常。这是由于Spring Boot（默认情况下）的工作原理。
您的Main课程已在spring包中定义。 Spring Boot会自动扫描此软件包及其所有子软件包。但是你的dao等在hibernate中没有被Spring Boot组件扫描覆盖。
添加@ImportResource("location-of-your/applicationContext.xml")或只是将@ComponentScan({"spring","hibernate"})添加到您的主类，或将您的DAO移动到spring的子包。
你的代码也有缺陷，你使用Spring然后使用Spring，不要自己配置hibernate。为此使用LocalSessionFactoryBean让Spring为您处理所有这些。
@SpringBootApplication
public class Main {
public static void main(final String[] args) throws Exception {
SpringApplication.run(Main.class, args);
}
@Bean
public LocalSessionFactoryBean sessionFactory() {
return new LocalSessionFactoryBean();
}
}
然而，我建议你删除所有这些，而不是使用普通的Hibernate并滚动另一个抽象的dao。将JPA与Spring Data JPA一起使用，可以为您节省大量代码。 （删除用户userDaoImpl和AbstractDao以及随附的所有接口。
您的userDao会是这样的。
public interface userDao extends JpaRepository<User, Integer> {}
（是的，没有什么比这更好了，是的没有实施）。
然后，您还可以从sessionFactory课程中删除Main方法。您的userService需要更改，才能使用findAll代替list。
@Service("userService")
@Transactional
public class userServiceImpl implements userService {
@Autowired
userDAO dao;
public List<user> findAll() {
return dao.findAll();
}
...
}
一般建议是使用框架（并首先阅读一些文档），而不是尝试使用新框架的旧方法。
专业提示：使用已接受的命名约定userServiceImpl等在Java版本中不是真正的自定义，以大写字母UserServiceImpl开头。

答案 2 :(得分：0)
这可能是由您定义的多个<component-scan>引起的。最新的<context:component-scan base-package="spring.service" />正在生效。从例外情况来看，Spring确实在实例化服务bean。
只需使用
<context:component-scan base-package="spring.controller, hibernate.dao, hibernate.model,spring.service" />
答案 3 :(得分：0)
请在以下位置使用@Qualifier注释：
public class userController {
@Autowired
@Qualifier("userService")
userService userService;
和
@Service("userService")
@Transactional
public class userServiceImpl implements userService {
@Autowired
@Qualifier("userDAO")
userDAO dao;
并检查。
