使用 mongo 支持的数据库与基于 Spring Security 的身份验证混淆

Question

我正在尝试将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控制器代码的原因，该代码有效：

@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);
  }
}

用户身份验证服务：

@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;
  }

修改后的控制器：

@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>

提供的所有代码都更少地从另一个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>它时仍然将我重定向到登录表单。我也在log.debug(..)里面放了一些UserAuthenticationService，但我根本看不到任何一个..在大多数其他例子中，我什至看不到映射到的基本控制器方法\login，但我认为这是因为spring做了这个4我幕后？！

请注意，我没有使用任何权限和/或角色，因为它还没有在 db 中建模。在使用 spring security 时，这是必须的，因为大多数示例都包含角色和权限。

更新：（我在上面提到的代码上尝试过的东西）：

1）设置其他会话策略：（不起作用）

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) 用 @Autowired 注释替换 @Override（从另一个 SO 帖子中得到的 - 不工作）：

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

Answer 1

我可以解决这个问题..通过阅读这篇博客文章，事实证明，它是必要的！指定usernameParameter(..), passwordParameter(..)in config(HttpSecurity http)，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

如果没有这些参数设置，UserDetailsService则不会触发实现。

希望它对任何人都有帮助。
