jsf 2 @managedProperty永远不会在wildfly 8中设置

Question

使用此bean

处理模型

@ManagedBean(name="login")
@SessionScoped
public class LoginBean {

private String login ;
private String pwd ;

public String getLogin() {
    return login;
}
public void setLogin(String login) {
    this.login = login;
}
public String getPwd() {
    return pwd;
}
public void setPwd(String pwd) {
    this.pwd = pwd;
}

虚拟登录后，我需要使用我的@managedProperty来设置我的下一个bean：

//Only for proving concepts
@ManagedProperty(value="#{login}")
private LoginBean loginBean;

public LoginBean getLoginBean() {
    return loginBean;
}

public void setLoginBean(LoginBean loginBean) {
    this.loginBean = loginBean;
}

我需要设置nextPage的bean调用它：

@PostConstruct
public void init() {
  if (loginBean.getLogin()) {
     ...
  }
}

但是这个bean保持为null：

Caused by: java.lang.NullPointerException
at fr.maf.vega.web.control.RechercheDossierBean.init(RechercheDossierBean.java:441)

感谢您的建议...

注意： 使用以下方法获取@SessionScoped loginBean效果很好（但它似乎不属于最佳实践）：

 public static Object getManagedBean(final String beanName) {
    FacesContext fc = FacesContext.getCurrentInstance();
    Object bean;

    try {
        ELContext elContext = fc.getELContext();
        bean = elContext.getELResolver()
                .getValue(elContext, null, beanName);
    } catch (RuntimeException e) {
        throw new FacesException(e.getMessage(), e);
    }

    if (bean == null) {
        throw new FacesException(
                "Managed bean with name '"
                        + beanName
                        + "' was not found. Check your faces-config.xml or @ManagedBean annotation.");
    }

    return bean;
}
