2、错误原因

 

public interface UserDao
{
       public List<User> findAll();
}

@Repository
public class UserDaoImpl implements UserDao
{
       @Override
       public List<User> findAll()
       {
             return null;
       }
}

public interface UserService
{
       public List<User> findAll();
}

public class UserServiceImpl implements UserService
{
      @Autowired
      private UserDao userDao;

      @Override
      public List<User> findAll()
      {
             return userDao.findAll();
      }
}

@Controller
@RequestMapping("/user")
public class UserController
{
      @Autowired
      private UserService userService;

      @RequestMapping(value = "findAll")
      public void findAll() 
      {
	userService.findAll();
      }
}

 

     导致这个错误的原因是Service实现缺少@Service

 

3、解决办法

 

public interface UserDao
{
       public List<User> findAll();
}

@Repository
public class UserDaoImpl implements UserDao
{
       @Override
       public List<User> findAll()
       {
             return null;
       }
}

public interface UserService
{
       public List<User> findAll();
}

@Service
public class UserServiceImpl implements UserService
{
      @Autowired
      private UserDao userDao;

      @Override
      public List<User> findAll()
      {
             return userDao.findAll();
      }
}

@Controller
@RequestMapping("/user")
public class UserController
{
      @Autowired
      private UserService userService;

      @RequestMapping(value = "findAll")
      public void findAll() 
      {
	userService.findAll();
      }
}
