Question

亲爱的程序员，

上下文是下一个：完成注册表格并发送后，用户将自动进行身份验证并重定向到主页，而不必返回登录表格即可登录。

应用程序安全性由Spring Security管理。我正在尝试在应用程序中实现此新功能，但是它不起作用。

我在将SpringManager中的authenticationManager注入时特别遇到问题，请看下面的代码：

Class SignUpMB：

@RequestScope
@Component
public class SignUpMB {

    @Autowired
    private UserService userService;

    @Autowired
    private SignupService signUpService;

    private User user = new User();
    private ProfileUser profileUser = new ProfileUser();

    private String confirmPw;

    @RequestMapping(value = "/account/signup", method = RequestMethod.POST)
    public String createNewUser(@ModelAttribute("user") User user, BindingResult result, HttpServletRequest request, HttpServletResponse response) {

        userService.addUser(user, profileUser);


        signUpService.authenticateUserAndSession(user, request);
        return "../index.xhtml";

    }
...
}

Class SignupService：

@Service
public class SignupService {

    @Autowired
    protected AuthenticationManager authenticationManager;

    /*@Autowired
    RequestCache requestCache;*/

    public void authenticateUserAndSession(User user, HttpServletRequest request) {
        String username = user.getMail();
        String password = user.getPassword();
        UsernamePasswordAuthenticationToken token = new UsernamePasswordAuthenticationToken(username, password);

        request.getSession();

        token.setDetails(new WebAuthenticationDetails(request));
        Authentication authenticationUser= authenticationManager.authenticate(token);

        SecurityContextHolder.getContext().setAuthentication(authenticationUser);

    }

}

现在按照错误进行操作：

请问，有什么办法可以解决吗？真是谢谢你。

重写authenticationManagerBean()的{{1}}方法以将WebSecurityConfigurerAdapter手动公开为spring bean。

AuthenticationManager

您只能自动装配Spring托管的bean。

注册用户后自动登录
