我在AutoWired注释中有一个问题，我是 Spring 天的新手请通过下面的代码并帮助我解决这个代码与JSF和Hibenate的完美结合现在我正在集成Spring框架工作 . 和我正在使用的依赖关系请指导我是否需要对UserDetailsVO和UserDetailsHelper类使用componentsnet注释我也使用了服务和Repository注释，并且我在managedbean setter中制作了限定符和AutoWired（required = true）方法，但仍然没有用 .

在Spring上下文加载调度程序servlet.xml文件时，正在加载用于泛型Crud操作的Abstract Dao类
public abstract class AbstractDao<T, ID extends Serializable> implements Dao<T, ID> {
private final Class<T> persistentClass;
// private SessionFactory sessionFactory = HibernateUtil.getSessionFactory();
@Autowired
private SessionFactory sessionFactory;
@SuppressWarnings("unchecked")
public AbstractDao(){
this.persistentClass =(Class<T>) ((ParameterizedType)this.getClass().getGenericSuperclass()).getActualTypeArguments()[0];
}
protected Session getSession(){
return this.sessionFactory.getCurrentSession();
}
public Class<T> getPersistentClass(){
return persistentClass;
}
@Override
public T findById(ID id) {
this.getSession().getTransaction().begin();
return (T) this.getSession().load(this.getPersistentClass(), id);
}
}
通用接口的Dao接口我也需要注释接口（我不这么认为）
public interface Dao<T, ID> {
public List<T> findAll();
public T findById(ID id);
}
用户详细信息Dao接口特定类接口
public interface UserDetailsDao extends Dao<UserDetails, String> {
}
The UserDetailsDao Impl and its Implemetation
@Repository("userDetailsDaoImpl")
public class UserDetailsDaoImpl extends AbstractDao<UserDetails, String>
implements UserDetailsDao {
}
UserDetailsService接口是服务接口
public interface UserDetailsService extends UserDetailsDao {
}
用户详细信息Dao Service Impl及其实现Spring Service类，如标准所示，并将接口注释为自动连线是否正确？
@Service("userDetailsServiceImpl")
@Transactional
public class UserDetailsServiceImpl implements UserDetailsService {
@Autowired
UserDetailsDao userDetailsDao;
@Override
public List<UserDetails> findAll() {
return userDetailsDao.findAll();
}
@Override
public UserDetails findById(String id) {
return userDetailsDao.findById(id);
}
}
UserDetailsVo用于Do to Vo转换的Pojo类这简单地用于DO对象之间的简单转换，这是用hibernate注释复制的
@Component("userVo")
public class UserDetailsVo implements Serializable {
private String userId;
private String userName;
private String emailId;
private boolean status;
private String userLevel;
public String getUserId() {
return userId;
}
public void setUserId(String userId) {
this.userId = userId;
}
//
}
The Helper Class
@Service("userHelper") // the helper class to used for business logics and some convertions please help me with below code style i'm following is it correct as i'm passing new object when converting to VO to DO vice versa
public class UserDetailsHelpler实现Serializable {
private static final Logger logger = Logger.getLogger(UserDetailsHelpler.class);
/**
*
*/
private static final long serialVersionUID = 1L;
private UserDetailsServiceImpl usersImpl;
@Autowired
public void setUsersImpl(UserDetailsServiceImpl usersImpl) {
this.usersImpl = usersImpl;
}
public UserDetailsVo saveUserDetails(UserDetailsVo vo) {
return userDetailsDOTOVOConvertor(usersImpl.save(userDetailsVOTODOConvertor(new UserDetails(), vo, vo.getUserId())), new UserDetailsVo());
}
}
Managed Bean类JSF ManagedBean类与JSF2.2只有注释，在faces配置中我也添加了 spring 视图解析器 .
@ManagedBean(name="userDetailsManagedBean")
@SessionScoped
public class UserDetailsMangedBean implements Serializable {
private static final long serialVersionUID = 1L;
private static final Logger logger = Logger.getLogger(UserDetailsMangedBean.class);
private UserDetailsVo users;
private UserDetailsHelpler helpler;
private String loadValidValues;
private boolean readOnce;
private List<UserDetailsVo> usersList;
public UserDetailsMangedBean() {
logger.info("Inside the UserdetailsManagedBean:" );
if(null == users) users = new UserDetailsVo();
}
public String getLoadValidValues() {
if(!readOnce) {
logger.info("Helper value " + helpler);
usersList = helpler.readUserDetails();
readOnce = true;
}
return loadValidValues;
}
public void setLoadValidValues(String loadValidValues) {
this.loadValidValues = loadValidValues;
}
public UserDetailsVo getUsers() {
return users;
}
@Autowired
public void setUsers(UserDetailsVo users) {
this.users = users;
}
public UserDetailsHelpler getHelpler() {
return helpler;
}
@Autowired
public void setHelpler(UserDetailsHelpler helpler) {
this.helpler = helpler;
}
public List<UserDetailsVo> getUsersList() {
return usersList;
}
public void setUsersList(List<UserDetailsVo> usersList) {
this.usersList = usersList;
}
}
Stack跟踪明确表示它未能将HelperClass创建为bean，而UserDetails服务Impl存在依赖性问题，这是我迷路的地方我尝试了一些更改，如autowired（required = true）限定符（“userHelper”） ）将服务注释添加到UserDetailsHelper和UserDetailsVo等但仍然是同一个问题 .
