来自其他Bean的JSF Bean属性

我尝试将一个ManagedBean（SessionScoped）（loginBean）的属性带到另一个（RequestScoped）ManagedBean（newsBean）中：

和新闻豆：

public class NewsBean {

@ManagedProperty("#{loginBean.user.nickname}")
private String nickname;

private String title;
private String description;

/**
 * Creates a new instance of NewsBean
 */
public NewsBean() {
}

是的，我还为user中的昵称声明了getter/setter

就用吧

美好的谢谢-从未听说过：我对此有问题：ManagedBeanCreationException:不知道为什么：/？也许你忘了塞特？好吧，等等：我在我的问题中发布了一个完整的豆子声明；）setter也应该在

NewsBean

中，正如异常消息试图告诉您的那样。JSF还应该如何设置它？

@ManagedBean
@SessionScoped
public class LoginBean {
public LoginBean() {
    email = "";
    pwd = "";
    device = "";
    user = null;
}

private String email;
private String pwd;
private User user;
private String device;
/**
 * @return the user
 */
public User getUser() {
    return user;
}

/**
 * @param user the user to set
 */
public void setUser(User user) {
    this.user = user;
}

public class NewsBean {

@ManagedProperty("#{loginBean.user.nickname}")
private String nickname;

private String title;
private String description;

/**
 * Creates a new instance of NewsBean
 */
public NewsBean() {
}

@ManagedBean
@ViewScoped
public class NewsBean {

    @ManagedProperty("#{loginBean.user.nickname}")
    private String author;

    // ...
}
