覆盖注入对象

我对关于注入对象改变的CDI行为有点困惑。覆盖注入对象

我有一个简单的用户级包含登录名和密码。我为CDI生成一个对象：

public class SessionService { 

    @LoggedIn 
    @Produces @SessionScoped 
    public User loggedInUser() { 
     return new User("login", "pass"); 
    } 
}

在下一步中，用户打开登录视图，登录控制器检查凭证。

@Named 
@SessionScoped 
public class LoginController extends Controller implements Serializable { 

    private static final long serialVersionUID = 6047784887724513434L; 

    @Inject 
    UserService userService; 

    @Inject 
    Credentials credentials; 

    @Inject 
    @LoggedIn 
    User currentUser; 

    public void doLogin() { 
     User check = userService.findUser(credentials.getLogin()); 
     if((check != null) && (check.getPasswort().equals(SHA256.hash(credentials.getPasswort())))) { 
      currentUser = check; 
      FacesRedirect.fromOutcome("login.success"); 
     } else { 
      addErrorMessage("loginFailed"); 
     } 
    } 
}

当我试着使用覆盖最初产生currentUser对象的“校验” - 用户这并不工作 - 我没有得到一个错误，但在其他类被注入的对象是一样的像之前一样。当我调用注入的currentUser对象的setLogin（）/ setPassword（）方法时，所有其他类都可以使用这些更改。

currentUser.setId(check.getId()); 
currentUser.setLogin(check.getLogin()); 
currentUser.setPasswort(check.getPassword());

是否有另一种方法来覆盖整个对象而不是调用所有setters？

第一次尝试我在LoginController中使用@Produces，但是当我将它注入Filter时，启动失败。

感谢您的帮助，托比亚斯

====================编辑============== ======

像@atamanroman建议，我删除了SessionService并已将此添加的LoginController：

@Produces 
@LoggedIn 
public User getCurrentUser() { 
    return currentUser; 
}

我用javax.enterprise.context.SessionScoped为控制器SessionScope，该LoginFilter看起来是这样的：

package de.mad_onion.thweb.util; 

import java.io.IOException; 

import javax.inject.Inject; 
import javax.inject.Named; 
import javax.servlet.Filter; 
import javax.servlet.FilterChain; 
import javax.servlet.FilterConfig; 
import javax.servlet.ServletException; 
import javax.servlet.ServletRequest; 
import javax.servlet.ServletResponse; 
import javax.servlet.annotation.WebFilter; 
import javax.servlet.http.HttpServletRequest; 
import javax.servlet.http.HttpServletResponse; 
import javax.servlet.http.HttpSession; 

import de.mad_onion.thweb.domain.User; 

@Named("loginFilter") 
@WebFilter(filterName = "LoginFilter", urlPatterns = {"/einsatz.xhtml"}) 
public class LoginFilter implements Filter { 

    @Inject 
    @LoggedIn 
    User currentUser; 

    @Override 
    public void destroy() { 
     // TODO Auto-generated method stub 

    } 

    @Override 
    public void doFilter(ServletRequest request, ServletResponse response, 
      FilterChain fc) throws IOException, ServletException { 

     HttpServletResponse httpResponse = (HttpServletResponse)response; 
     HttpServletRequest httpRequest = (HttpServletRequest)request; 
     HttpSession httpSession = httpRequest.getSession(); 

     if(currentUser == null) { 
      System.out.println("No user"); 
     } else { 
      System.out.println("User:"); 
      System.out.println(currentUser.toString()); 
     } 
     fc.doFilter(request, response); 

    } 

    @Override 
    public void init(FilterConfig arg0) throws ServletException { 
     System.out.println("Filter initialized"); 
    } 
}

如果我尝试部署应用程序，我得到这个堆栈跟踪：

如何将当前用户注入其他类？如果他们从你的LoginController中得到它，覆盖用户对象应该没问题，如果他们在登录后得到它。 – atamanroman 2012-07-16 12:20:53

我只需通过@Inject @LoggedIn User currentUser注入它。该视图在登录后也被调用，但不能像上面描述的那样工作。 – 2012-07-16 12:46:32

如果注入其他豆类当前用户与@Inject @LoggedIn容器总是会调用与@Producer注释的方法唉创建新用户（return new User("login", "pass");）。只有在您的LoginController中才会设置正确的用户，这与您的SessionService完全没有关系。我想删除SessionService并创建currentUserLoginController这是用@Produces @LoggedIn标记将解决您的逻辑问题的吸气剂。

真正的问题似乎是注入到您的过滤器不起作用。请问您是否可以验证您是否使用了正确的@SessionScoped注释（不是来自jsf）并使用详细的错误消息显示您的过滤器实现？

正如here所述，您必须用@WebFilter/@命名而不是@ManagedBean注释您的Filter类，否则@Inject将不起作用。混合两者可能会导致不必要的头痛。

我更新了关于你的想法的最初问题。 – 2012-07-16 16:07:15

我不确定'@WebServlet'和'@ Named'是否一起工作。 '@ WebServlet'应该足够了。你有没有尝试直接将'LoginController'注入到servlet中并从那里调用getter？ – atamanroman 2012-07-16 16:28:48

我删除了@Named，和以前一样有异常。现在我直接注入LoginController并调用getCurrentUser（）方法，一切都像魅力一样... – 2012-07-16 16:48:16

我有几个“奇特”的方法来做到这一点，但老实说，使用setter是最干净的方式来做到这一点。
