我有使用 jsf 2.0 和 spring 3.0 +hibernate 4 的 web 应用程序问题是:jsf managed beans can't use spring beans using dependency injection 还有我的配置文件:

Rq 当我像 @ManagedBean(name="userMB") @RequestScoped 那样更改 Mybean 并放入 @ManagedProperty(value="#{Service}") 它在 jsf 页面上被识别但有错误

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();
    }

}

这是我的托管 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;
}
}

这是我的应用程序上下文春天

持有 spring 立体类型 bean 的类(这里你的支持 bean 持有它们)应该通过 Spring 工厂实例化,但支持 bean 是由 JSF 框架创建的。只需使用 Spring EL Resolvers for JSF 来克服这个问题。他是一个相关的讨论文档

此外,请确保您在通过 web.xml 加载的 Web 应用程序上下文中配置了 spring bootstrap
