OpenShif-JSF2.0,Primefaces4 e CDI焊接-控制器解析为null

Question

嗨，我对OpenShift有个问题。错误是：

PropertyNotFoundException：目标不可达，标识符“登录控制器”解析为空

public class Login {
    private int codigo;
    private String username;
    private String password;
    // getters and setters
}

import javax.enterprise.context.SessionScoped;    
import javax.inject.Inject;
import javax.inject.Named;
//others imports

@Named
@SessionScoped
public class LoginController implements Serializable {    
    private static final long serialVersionUID = 4560576357452534579L;    
    @Inject
    private LoginDAO loginDao;        
    private Login login;

    // others fields        
    // getters and setters of Login    
}

<p:inputText class="form-control" id="username" value="#{loginController.login.username}" />
<p:password class="form-control" id="password" value="#{loginController.login.password}" />

您注入的是loginDao但不是login。但你引用的是登录。除非你在其他地方初始化登录，否则你会得到一个NPE。
