Error creating bean with name

Question

I'm using SpringMVC for a web app as well as to inject my sessionFactory for Hibernate.

When I run my application, I get the following error...

I'm not sure why the autoInject isn't working. I have put all my XML configuration into servlet-context...

The code for the userManagementController is...

import java.text.DateFormat; import java.util.Date; import java.util.Locale;  import org.assessme.com.dao.UserDaoImpl; import org.assessme.com.entity.User; import org.assessme.com.service.UserService; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.ResponseBody;  @Controller @RequestMapping(value = "/userManagement") public class UserManagementController {      private static final Logger logger = LoggerFactory             .getLogger(HomeController.class);      @Autowired     private UserService userService;      /**      * Simply selects the home view to render by returning its name.      */     @RequestMapping(value = "/", method = RequestMethod.GET)     public Object home(Locale locale, Model model) {          logger.info("User management view controller loaded...");          return "userManagement";     }      @RequestMapping(value = "/getUser", method = RequestMethod.GET)     @ResponseBody     public User data(Locale locale, Model model) {         logger.info("getUser controller loaded...");         User user = userService.getById(1L);         System.out.println("firstName is " + user.getFirstName());         return user;      }  } 

The userService is userService.java...

import org.assessme.com.entity.User;  public interface UserService {     public User getById(Long id); } 

which is used by...

@Service("userService") @Transactional(propagation = Propagation.SUPPORTS, readOnly = true) public class UserServiceImpl implements UserService {      @Autowired     private UserDao userDao;       public UserServiceImpl() {     }      @Transactional(propagation = Propagation.REQUIRED, readOnly = true)     public User getById(Long id) {         return userDao.getById(id);     }  } 

Can anyone give me any pointers? Is there something I need to add to my XML? I'm working off the tutorial on...

http://www.roseindia.net/tutorial/spring/spring3/web/spring-3-mvc-and-hibernate3-example-part3.html

And I don't see how they autowire

@Autowired     private ArticleService articleService; 

in ArticleController.java

Thanks,

David

Answer 1

I think it comes from this line in your XML file:

<context:component-scan base-package="org.assessme.com.controller." /> 

Replace it by:

<context:component-scan base-package="org.assessme.com." /> 

It is because your Autowired service is not scanned by Spring since it is not in the right package.

Answer 2

It looks like your Spring component scan Base is missing UserServiceImpl

<context:component-scan base-package="org.assessme.com.controller." />
