错误集成jsf +spring +hibernate +managedbean

Question

我有一个使用jsf 2.0和spring 3.0 +hibernate的web应用程序，问题是:jsf管理的bean不能使用使用依赖注入的spring bean。

Rq当我改变Mybean @ManagedBean(name="userMB")@RequestScoped我把@ManagedProperty(value="#{Service}")，它被识别在jsf页面，但有错误

package com.ardia.service;
import java.util.List;
import com.ardia.model.Composant;
public interface ComposantService {
    void inserComposant(Composant comp);
    Composant getComposantById(int compId);
    Composant getComposant(String compname);
    List<Composant> getComposants();
}

这是我的服务

package com.ardia.service;
import java.util.List;
import org.hibernate.Criteria;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
import com.ardia.model.Composant;
@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();
    }
}

This is My Managed Bean

package ardia.beans;
import java.io.Serializable;
import java.util.List;
import javax.annotation.PostConstruct;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Component;
import com.ardia.model.Composant;
import com.ardia.service.ComposantService;
@Component("compBean")
@Scope("session")
public class CoposantBean implements Serializable{
@Autowired
private 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;
}
}

this is My application context spring

和当我试图有一个列表与datatable . managedbean它不被识别

 <p:dataTable id="cars" var="fab" value=***"#{here is not figure*** paginator="true" rows="10"  >  

Answer 1

持有spring立体类型bean的类(这里是支持bean持有它们)应该通过spring工厂实例化，但是支持bean是由JSF框架创建的。只需为JSF使用Spring EL解析器就可以克服这个问题。他是一个相关的讨论和文档

另外，确保在web应用程序上下文中配置了spring引导，通过web.xml

加载。
