Question

我已经创建了一个添加方法，我使用了jsf和hibarnate框架，但是出现了一个值得注意的例外，她阻止了我。

这是我的班级豆类

package controller;

import java.io.Serializable;
import javax.faces.bean.RequestScoped; 
import org.springframework.beans.factory.annotation.Autowired;
import model.Client;
import javax.faces.bean.ManagedBean;
import service.ClientService;

@ManagedBean(name="clientBean")
@RequestScoped
public class ClientBeanManger implements Serializable {

    private static final long serialVersionUID = 1L;
    private static final String SUCCESS = "success";
    private static final String ERROR   = "error";

    //Spring User Service is injected...
    @Autowired
    ClientService clientService;
    private Client client;




    public Client getClient() {
        return client;
    }


    public void setClient(Client client) {
        this.client = client;
    }


    public ClientBeanManger() {

    }

    private int idClient;
    private String nomClient;
    private String adresseClient;
    private String telephoneClient;
    private String mailClient; 



    // Add client @return String - Response Message

    public void addClient(Client client) {
        client.setIdClient(idClient);
        client.setNomClient(nomClient);
        client.setAdresseClient(adresseClient);
        client.setTelephoneClient(telephoneClient);
        client.setMailClient(mailClient);
        clientService.add(client);          
    }


    //Getter and  setter 
    public ClientService getClientService() {
        return clientService;
    }

    public void setClientService(ClientService clientService) {
        this.clientService = clientService;
    }

    public int getIdClient() {
        return idClient;
    }

    public void setIdClient(int idClient) {
        this.idClient = idClient;
    }

    public String getNomClient() {
        return nomClient;
    }

    public void setNomClient(String nomClient) {
        this.nomClient = nomClient;
    }

    public String getAdresseClient() {
        return adresseClient;
    }

    public void setAdresseClient(String adresseClient) {
        this.adresseClient = adresseClient;
    }

    public String getTelephoneClient() {
        return telephoneClient;
    }

    public void setTelephoneClient(String telephoneClient) {
        this.telephoneClient = telephoneClient;
    }

    public String getMailClient() {
        return mailClient;
    }

    public void setMailClient(String mailClient) {
        this.mailClient = mailClient;
    }


}

           </tr>
          </table>
         </h:form>
    </h:body>
    </html>

错误：

Etat HTTP 500 - javax.el.PropertyNotFoundException: /pages/index.xhtml @35,97 action="#{clientBean.client.addClient}": Target Unreachable, 'client' returned null

我知道还有很多其他问题都有相同的标题，但没有一个有效.plz plz帮帮我，我开始放手了我

@AutoWired不会将spring bean注入jsf bean;他们处于两种不同的环境中。

只有当@Autowired也是Spring MVC管理的bean时，Spring才能使用ClientBeanManger注入bean。从你的问题编写方式和评论来看，我认为你需要探索连接Spring bean和JSF bean的基础知识。

看看以下
