java - Spring应用程序中的NoSuchBeanDefinitionException

转载作者：太空宇宙更新时间：2023-11-04 14:34:11

我正在创建一个使用 REST 的应用程序。目前我的 Controller 是使用 ServiceMockImplementation 实现的，但我打算使用数据库(而不是对联系人的值进行硬编码)。当由模拟实现使用时， Restful 客户端工作正常(并在服务器上运行)，但当我添加 DAO 实现时，它崩溃并给我一个 NoSuchBeanDefinitionException 即使 bean“contactDao”被注释作为我的 DAOImplementation 类中的 @Repository("contactDao")。

这是我的RestfulClientMain:

public class RestfulClientMain {

    private static final String URL_GET_ALL_CONTACTS = "http://localhost:8080/Contact/contacts";
    private static final String URL_GET_CONTACT_BY_ID = "http://localhost:8080/Contact/contacts/{id}";
    private static final String URL_CREATE_CONTACT = "http://localhost:8080/Contact/contacts/";
    private static final String URL_UPDATE_CONTACT = "http://localhost:8080/Contact/contacts/{id}";
    private static final String URL_DELETE_CONTACT = "http://localhost:8080/Contact/contacts/{id}"; 

    public static void main(String[] args) {

        GenericXmlApplicationContext ctx = new GenericXmlApplicationContext();
        ctx.load("classpath:restful-client-app-context.xml");
        ctx.refresh();

        Contacts contacts;
        Contact contact;
        RestTemplate restTemplate = ctx.getBean("restTemplate", RestTemplate.class);

        // Test retrieve all contacts
        System.out.println("Testing retrieve all contacts:");
        contacts = restTemplate.getForObject(URL_GET_ALL_CONTACTS, Contacts.class);
        listContacts(contacts); 

        // Test retrieve contact by id
        System.out.println("Testing retrieve a contact by id :");
        contact = restTemplate.getForObject(URL_GET_CONTACT_BY_ID, Contact.class, 1);
        System.out.println(contact);
        System.out.println("");

        // Test update contact
        contact = restTemplate.getForObject(URL_UPDATE_CONTACT, Contact.class, 1);
        contact.setFirstName("Kim Fung");
        System.out.println("Testing update contact by id :");
        restTemplate.put(URL_UPDATE_CONTACT, contact, 1);
        System.out.println("Contact update successfully: " + contact);
        System.out.println(""); 

        // Testing delete contact
        restTemplate.delete(URL_DELETE_CONTACT, 1);
        System.out.println("Testing delete contact by id :");
        contacts = restTemplate.getForObject(URL_GET_ALL_CONTACTS, Contacts.class);
        listContacts(contacts);

        // Testing create contact
        System.out.println("Testing create contact :");
        Contact contactNew = new Contact();
        contactNew.setFirstName("JJ");
        contactNew.setLastName("Gosling");
        contactNew.setBirthDate(new Date());
        contactNew = restTemplate.postForObject(URL_CREATE_CONTACT, contactNew, Contact.class);
        System.out.println("Contact created successfully: " + contactNew);       

    }

    private static void listContacts(Contacts contacts) {
        for (Contact contact: contacts.getContacts()) {
            System.out.println(contact);
        }   
        System.out.println("");
    }

}

这是我的ContactController:

import javax.servlet.http.HttpServletResponse;
import org.slf4j.*;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.*;
import org.springframework.web.context.request.WebRequest;
import com.aucklanduni.spring.webservices.domain.*;
import com.aucklanduni.spring.webservices.service.ContactService;


@Controller
@RequestMapping(value="/contacts")
public class ContactController {

    final Logger logger = LoggerFactory.getLogger(ContactController.class);


    @Autowired
    private ContactService contactService;

    @RequestMapping(method = RequestMethod.GET)
    @ResponseBody
    public Contacts listData(WebRequest webRequest) {
        return new Contacts(contactService.findAll());
    }   

    @RequestMapping(value="/{id}", method=RequestMethod.GET)
    @ResponseBody
    public Contact findContactById(@PathVariable Long id) {     
        return contactService.findById(id);
    }

    @RequestMapping(value="/", method=RequestMethod.POST)
    @ResponseBody
    public Contact create(@RequestBody Contact contact, HttpServletResponse response) {
        logger.info("Creating contact: " + contact);
        contactService.save(contact);
        logger.info("Contact created successfully with info: " + contact);
        response.setHeader("Location",  "/contacts/" + contact.getId());
        return contact;
    }

    @RequestMapping(value="/{id}", method=RequestMethod.PUT)
    @ResponseBody
    public void update(@RequestBody Contact contact, @PathVariable Long id) {
        logger.info("Updating contact: " + contact);
        contactService.save(contact);
        logger.info("Contact updated successfully with info: " + contact);
        //return contact;
    }   

    @RequestMapping(value="/{id}", method=RequestMethod.DELETE)
    @ResponseBody
    public void delete(@PathVariable Long id) {
        logger.info("Deleting contact with id: " + id);
        Contact contact = contactService.findById(id);
        contactService.delete(contact);
        logger.info("Contact deleted successfully");
    }   

}

这是我的 ContactMockImplementation。目前，您可以看到它包含硬编码值，但作为注释，我已经包含了解决此错误后代码实际应该执行的操作。即与 DAO 交互(从数据库中检索联系人)。

import java.util.*;
import org.joda.time.DateTime;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.*;
import com.aucklanduni.spring.webservices.domain.*;

@Service("contactService")
@Component
public class ContactServiceMockImplementation implements ContactService {

    private Contacts _contacts;

    //private ContactDao contactDao;

    public ContactServiceMockImplementation() {
        Contact contact1 = new Contact();
        contact1.setId(1L);
        contact1.setVersion(1);
        contact1.setFirstName("Clint");
        contact1.setLastName("Eastwood");
        contact1.setBirthDate(new Date());

        Contact contact2 = new Contact();
        contact2.setId(1L);
        contact2.setVersion(1);
        contact2.setFirstName("Robert");
        contact2.setLastName("Redford");
        contact2.setBirthDate(new Date());

        Contact contact3 = new Contact();
        contact3.setId(1L);
        contact3.setVersion(1);
        contact3.setFirstName("Michael");
        contact3.setLastName("Caine");
        contact3.setBirthDate(new Date());

        List<Contact> contactList = new ArrayList<Contact>();
        contactList.add(contact1);
        contactList.add(contact2);
        contactList.add(contact3);

        _contacts = new Contacts(contactList);
    }

    @Override
    public List<Contact> findAll() {
        return _contacts.getContacts();
        //return contactDao.findAll();
    }

//  @Override
//  public List<Contact> findByFirstName(String firstName) {
//      List<Contact> results = new ArrayList<Contact>();
//      
//      for(Contact contact : _contacts.getContacts()) {
//          if(contact.getFirstName().equals(firstName)) {
//              results.add(contact);
//          }
//      }
//      return results;
//  }

    @Override
    public Contact findById(Long id) {
        Contact result = null;

        for(Contact contact : _contacts.getContacts()) {
            if(contact.getId() == id) {
                result = contact;
                break;
            }
        }
        return result;
        //return contactDao.findById(id);
    }

    @Override
    public Contact save(Contact contact) {
        return contact;
        //return contactDao.save(contact);
    }

    @Override
    public void delete(Contact contact) {
        // TODO Auto-generated method stub
        //contactDao.delete(contact);
    }

}

这是我的 ContactDao - 这就是给我带来错误的原因。

import java.util.List;
import javax.annotation.Resource;
import org.hibernate.SessionFactory;
import org.slf4j.*;
import org.springframework.stereotype.*;
import org.springframework.transaction.annotation.Transactional;
import com.aucklanduni.spring.webservices.domain.Contact;

@Repository("contactDao")
@Component
@Transactional
public class ContactDaoImpl implements ContactDao {

    private Logger _logger = LoggerFactory.getLogger(ContactDaoImpl.class);

    private SessionFactory _sessionFactory; 

    public SessionFactory getSessionFactory() {
        return _sessionFactory;
    }

    @Resource
    public void setSessionFactory(SessionFactory sessionFactory) {
        this._sessionFactory = sessionFactory;
        _logger.debug("SessionFactory class: " + sessionFactory.getClass().getName());
    }

    @Transactional(readOnly=true)
    public List<Contact> findAll() {
        List<Contact> result = _sessionFactory.getCurrentSession().createQuery("from Contact c").list();
        return result;
    }

    public List<Contact> findAllWithDetail() {
        return _sessionFactory.getCurrentSession().getNamedQuery("Contact.findAllWithDetail").list();
    }

    public Contact findById(Long id) {
        return (Contact) _sessionFactory.getCurrentSession().
                getNamedQuery("Contact.findById").setParameter("id", id).uniqueResult();
    }

    public Contact save(Contact contact) {
        _sessionFactory.getCurrentSession().saveOrUpdate(contact);
        _logger.info("Contact saved with id: " + contact.getId());
        return contact;
    }

    public void delete(Contact contact) {
        _sessionFactory.getCurrentSession().delete(contact);
        _logger.info("Contact deleted with id: " + contact.getId());
    }

}

启动服务器时，这是我收到的错误:

ERROR: org.springframework.web.servlet.DispatcherServlet - Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'contactDao': Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.hibernate.SessionFactory] found for dependency: expected at least 1 bean which qualifies as

我目前陷入困境，因为我不太确定如何将我的 ContactService 与我的 ContactDao 链接起来(而不是使用 MockImplementation 方法)。任何帮助都感激不尽。谢谢!

最佳答案

@Resource 似乎是在按名称接线的基础上工作，而不是允许按类型接线。您可以使用 @Autowired 代替，或者如果您确实想坚持使用符合 JSR-250 的注释，请使用 @Resource(name="springSessionFactory")。最后一种选择是将 bean 重命名为 sessionFactory，这样就可以修复所有内容。
