我有一个使用 JSF 2.0、Spring 3.0 和 Hibernate 4 的 Web 应用程序。经过两天的设置，我终于在我的数据表中得到了一个列表，但我也遇到了一个问题。我可以这么说，因为我在控制台中看到有关服务类使用的错误：

我的服务等级：

package com.ardia.service; 
@Service("compService")
@Transactional
public class ComposantImp implements ComposantService {


    @Autowired
    SessionFactory sessionFactory;


    @Override
    public void inserComposant(Composant comp) {
        // TODO Auto-generated method stub

        sessionFactory.getCurrentSession().saveOrUpdate(comp);
    }

    @Override
    public Composant getComposantById(int compId) {
        // TODO Auto-generated method stub
        return (Composant) sessionFactory.
                  getCurrentSession().
                  get(Composant.class, compId);
    }

    @Override
    public Composant getComposant(String compname) {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    @SuppressWarnings("unchecked")
    public List<Composant> getComposants() {
        // TODO Auto-generated method stub
        Criteria criteria = sessionFactory.
                  getCurrentSession().
                  createCriteria(Composant.class);
                return criteria.list();
    }

}

我的豆类：

package com.ardia.beans;
import java.util.List;
import javax.annotation.PostConstruct;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.ManagedProperty;
import javax.faces.bean.SessionScoped;
import com.ardia.model.Composant;
import com.ardia.service.ComposantService;

@ManagedBean(name="userMB")
@SessionScoped
public class Composantbeam {

    @ManagedProperty(value="#{compService}")
    ComposantService service;

    private List<Composant> list;

    @PostConstruct
    public void init() {
        list=service.getComposants();
    }

    public List<Composant> getList() {
        return list;
    }

    public void setList(List<Composant> list) {
        this.list = list;
    }

    public ComposantService getService() {
        return service;
    }

    public void setService(ComposantService service) {
        this.service = service;
    }

}

我的面孔-config.xml：

<faces-config
    xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd"

我的 JSF 页面中的数据表工作并返回值列表。

但最终我得到以下错误：

我没有一个名为Lcom.ardia.service但我有一个类com.ardia.service。

我从我的服务类中删除了注释。

通过 Spring 配置手动创建服务解决了我的问题。这是配置的相关部分：

<bean id="compService" class="com.ardia.service.ComposantImp">
    <property name="sessionFactory" ref="SessionFactory" />
</bean>

事实证明，JSF 和 Hibernate 不支持注释......
