我正在将SpringMVC用于Web应用程序以及为Hibernate注入sessionFactory。
当我运行我的应用程序时，我收到以下错误......

userManagementController的代码是......
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;
}
}
userService是userService.java ...
import org.assessme.com.entity.User;
public interface UserService {
public User getById(Long id);
}
用于......
@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);
}
}
任何人都可以给我任何指示吗？我需要添加到我的XML中吗？我正在研究教程......

我不知道他们如何自动装载
@Autowired
private ArticleService articleService;
谢谢，

答案 0 :(得分：26)
我认为它来自XML文件中的这一行：
<context:component-scan base-package="org.assessme.com.controller." />
将其替换为：
<context:component-scan base-package="org.assessme.com." />
这是因为Spring不会扫描您的Autowired服务，因为它不在正确的包中。
答案 1 :(得分：7)
看起来您的Spring组件扫描Base缺少UserServiceImpl
<context:component-scan base-package="org.assessme.com.controller." />
