java - 注册用户后自动登录

Question

亲爱的程序员 friend 们，

接下来的上下文是:用户填写并发送注册表后，将自动进行身份验证并重定向到主页，而不必返回登录表单进行登录。

应用程序安全性由 Spring Security 管理。 我正在尝试在我的应用程序中实现这个新功能，但它不起作用。

我在将authenticationManager注入(inject)到我的SpringService中时遇到了问题，请看下面的代码:

类 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";

    }
...
}

类注册服务:

@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:

请问您知道如何解决这个问题吗？非常感谢。

重写WebSecurityConfigurerAdapter的authenticationManagerBean()方法以手动将AuthenticationManager公开为Spring bean。

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {
   @Bean(name = BeanIds.AUTHENTICATION_MANAGER)
   @Override
   public AuthenticationManager authenticationManagerBean() throws Exception {
       return super.authenticationManagerBean();
   }
}

您只能 Autowiring Spring 托管 bean。
