每次使用@Inject都会注入一个新实例 [英] @Inject is injecting a new instance every time i use it

问题描述

我有以下问题。
（jboss 7.1 as，jsf 2和myFaces扩展过滤器）

I have the following issue. (jboss 7.1 as, jsf 2 and myFaces extension filter)

两个托管bean。 （我已经清理了代码）。我想从NextBean检索LoginBean。问题在于，每次我注入bean时，都会得到一个LoginBean的新实例，而不是当前实例。我已经尝试过@Named（ name）之类的东西。 Bean本身（都是）都从jsf页面调用，并且所有数据都已设置，但是每次都注入一个新实例，而我无法弄清楚自己在做什么错！！！ $ b

Two managed beans. (I have cleaned up the code). I want to retrieve LoginBean from NextBean. The problem is that every time i inject the bean i get a new instance of LoginBean and not the current one. I have tried things like @Named("name"). The bean itself (both) are invoked from the jsf pages and all data is set, but a new instance is injected every time and i cant figure out what i'm doing wrong!!!

@Named
@SessionScoped
public class LoginBean implements Serializable {

    private static final long serialVersionUID = -8825740128333470396L;

    @EJB private UserDetailDao userDetailDao;

    private String description;
    public String getDscription() { return description; }

    public String submit() {
        userDetailDao.doSomething("test");

        description = "testing";

        return "next.xhtml";
    }
}

和第二个bean

@Named
@SessionScoped
public class NextBean extends SomeBean implements Serializable {

    private static final long serialVersionUID = -4654827059950265300L;

    @Inject private LoginBean loginBean;

    public String submit() {
        String description = loginBean.getDscription();

        return "login.xhtml";
    }
}

已设置说明，我可以看到在jsf页面中，但是我无法从NextBean访问它，因为它每次都会注入一个新实例！但是数据在会话中！

The "Description" is set and i can see it in the jsf page, but i cant access it from NextBean since it injects a new instance every time! But the data is in the session!

有什么提示吗？
预先感谢！

Any tips? Thanks in advance!

推荐答案

我在给豆子命名错误！并且未使用正确的@Produces：/

I was naming the beans wrong! and did not use proper @Produces :/

感谢您的时间小伙子们。

Thanks for your time lads.
