java - 与基于 Spring Security 的身份验证与 mongodb 后端数据库混淆

Question

我正在尝试让用户登录到一个网页，其中凭据存储在 mongodb 中。 我正在使用 spring boot 并且不知道 spring 安全功能。

这就是我最终使用以下有效 Controller 代码的原因:

@RequestMapping("/auth")
String auth(@ModelAttribute("credential") Credential credential) throws AuthenticationFailedException {
    handler.authenticateUser(credential);
    log.debug("user: " + credential.getUsername() + " authenticated successfully via /auth");
    return "main";
}

处理程序:

@Autowired
private UserRepository repository;

public boolean authenticateUser(Credential credential) throws AuthenticationFailedException {        
    User authenticatedUser = repository.findByCredentialUsername(credential.getUsername());

    if (authenticatedUser == null)
        throw new AuthenticationFailedException(
                "cant find any user with name: " + credential.getUsername());

    boolean matches = EncryptionUtils.matchEncryptedPassword(credential.getPassword(),
            authenticatedUser);

    if (!matches)
        throw new AuthenticationFailedException(
                "provided password is not matching password stored in database");

    return matches;
}

在意识到使用 spring-security 设置 servlet 过滤器等相对容易之后，我更改了我的代码，所以我最终得到了这个:

配置:

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

  @Autowired
  UserAuthenticationService userAuthService;

  @Bean
  public DaoAuthenticationProvider daoAuthenticationProvider() {
    DaoAuthenticationProvider provider = new DaoAuthenticationProvider();
    provider.setUserDetailsService(userAuthService);
    provider.setPasswordEncoder(new BCryptPasswordEncoder());
    return provider;
  }

  @Override
  protected void configure(HttpSecurity http) throws Exception {
    http.userDetailsService(userAuthService).authorizeRequests()
            .antMatchers("/register", "/", "/css/**", "/images/**", "/js/**", "/login")
            .permitAll().anyRequest().authenticated().and().
            formLogin().loginPage("/").and().sessionManagement()
            .sessionCreationPolicy(SessionCreationPolicy.STATELESS).and().csrf().disable();

  }

  @Override
  protected void configure(AuthenticationManagerBuilder auth) throws Exception {
    auth.authenticationProvider(daoAuthenticationProvider());
  }

安全网络初始化:

public class SecurityWebInit extends AbstractSecurityWebApplicationInitializer {
  public SecurityWebInit() {
    super(SecurityConfig.class);
  }
}

用户认证服务:

@Component
public class UserAuthenticationService implements UserDetailsService {
  private static final Logger log = Logger.getLogger(UserAuthenticationService.class);
  @Autowired
  private UserRepository repository;

  @Override
  public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        User user = repository.findByCredentialUsername(username);
        log.debug("called user auth service..");
        if (user == null)
            throw new UsernameNotFoundException("username :"+username+" not found.");
        else {
            AuthenticatedUser authUser = new AuthenticatedUser(user);
            return authUser;
        }
  }
}

AuthenticatedUser - 型号:

public class AuthenticatedUser implements UserDetails {  
  private User user; // user is my own model, not of spring-framework
  private static final Logger log = Logger.getLogger(AuthenticatedUser.class);

  public AuthenticatedUser(User user) {
      this.user = user;
  }
  .. //rest of interface impl. (any method returns true)

  //no roles or authorities modeled, yet
  @Override 
  public Collection<? extends GrantedAuthority> getAuthorities() {
      return null;
  }

修改后的 Controller :

@RequestMapping(method=RequestMethod.POST, value="/login")
String auth2(@RequestParam("username") String username, @RequestParam("password") String password) throws AuthenticationFailedException {
    Credential cred = new Credential();
    cred.setUsername(username);
    cred.setPassword(password);        
    handler.authenticateUser(cred);
    log.debug("user: " + cred.getUsername() + " authenticated successfully via /login");
    return "main";
}

模板:

<form method="post" action="/login" th:object="${credential}">
    <div class="form-group">
     <input type="email" th:field="*{username}" class="form-control"
      id="username" placeholder="Username/Email" />
    </div>
    <div class="form-group">
     <input type="password" th:field="*{password}"
      class="form-control" id="password" placeholder="Password" />
    </div>
    <button type="submit" class="btn btn-default login-button">Submit</button>
</form>

所有提供的代码，更多的是从其他教程和示例中聚集在一起。 当我通过基于表单的登录进行身份验证时，它确实有效。但是在我登录后，当我导航到 localhost:8080/<anyRestrictedUrl> 时它仍然将我重定向到登录表单。 我还放了一些 log.debug(..) UserAuthenticationService 内部, 但我根本看不到他们中的任何一个.. 在大多数其他示例中，我什至看不到映射到 \login 的基本 Controller 方法。 ，但我认为这是因为 spring 在幕后做了这 4 个我？!

请注意，我没有使用任何权限和/或角色，因为它们还没有在数据库中建模。在使用 spring security 时，这是必须具备的吗，因为大多数示例都包含角色和权限。

更新:(我在上述代码中尝试过的内容):

1) 设置其他 session 策略:(不工作)

http.userDetailsService(userAuthService).authorizeRequests()
    .antMatchers("/register", "/", "/css/**", "/images/**", "/js/**", "/login")
    .permitAll().anyRequest().authenticated().and().
    formLogin().loginPage("/").and().sessionManagement().sessionCreationPolicy(SessionCreationPolicy.ALWAYS).and().csrf().disable();

2) 将@Override 替换为@Autowired 注释(从另一个 SO 帖子中获取 - 不起作用):

@Autowired
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
    auth.authenticationProvider(daoAuthenticationProvider());
}

Answer 1

我可以解决这个问题.. 随着阅读this blog post事实证明，这是需要的!在 config(HttpSecurity http) 中指定 usernameParameter(..), passwordParameter(..)，这与许多基本示例或教程中的做法不同。所以依赖默认值是我的遗憾。我必须附加:

formLogin().loginPage("/")
       .loginProcessingUrl("/login")
       .failureUrl("/")
       .defaultSuccessUrl("/main")
       .usernameParameter("username") //needed, if custom login page
       .passwordParameter("password") //needed, if custom login page

没有这些参数设置，UserDetailsS​​ervice 实现不会被触发。

希望对大家有帮助。
