Question

我对有关注入物体更改的CDI行为感到有点困惑。

我有一个包含登录名和密码的简单用户类。我为CDI制作了一个对象：

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，登录控制器检查凭据。

@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");
        }
    }
}

当我尝试使用找到的“check”-user覆盖最初生成的currentUser-object时，这不起作用 - 我没有收到错误，但其他类中的注入对象与之前相同。当我调用注入的currentUser-object的setLogin（）/ setPassword（）方法时，这些更改可用于所有其他类。

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的setter？

在第一次尝试时，我在LoginController中使用了@Produces，但当我将其注入Filter时，启动失败。

感谢您的帮助，托拜厄斯

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

像@atamanroman建议的那样，我删除了SessionService并将其添加到LoginController：

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

我使用javax.enterprise.context.SessionScoped作为控制器SessionScope，LoginFilter如下所示：

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，我会得到这个堆栈跟踪：

Answer 1

如果您将当前用户注入@Inject @LoggedIn的其他bean，则容器将始终调用使用@Producer注释的方法，并创建一个新用户（return new User("login", "pass");）。只有在您的SessionService中没有任何内容的LoginController中才会设置正确的用户。我想删除SessionService并在currentUser中为LoginController创建一个标有@Produces @LoggedIn的getter将解决您逻辑中的问题。

真正的问题似乎是注入您的过滤器不起作用。请问您是否可以验证是否使用了正确的@SessionScoped注释（而不是来自jsf）并显示了详细的过滤器实现错误信息？

如前所述here，您必须使用@WebFilter / @ Named而不是@ManagedBean来注释您的Filter类，否则@Inject将无效。混合两者可能会导致意外的头痛。
