JWT认证机制实现

2.1 JWT基础概念

JWT（JSON Web Token）是一种开放标准（RFC 7519），用于在各方之间安全地传输信息。JWT由三部分组成：头部（Header）、载荷（Payload）和签名（Signature）。

2.2 JWT配置实现

@Configuration
@EnableWebSecurity
public class JwtSecurityConfig {
    
    @Bean
    public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
        http
            .csrf().disable()
            .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS)
            .and()
            .authorizeHttpRequests(authz -> authz
                .requestMatchers("/auth/**").permitAll()
                .anyRequest().authenticated()
            )
            .addFilterBefore(new JwtAuthenticationFilter(), UsernamePasswordAuthenticationFilter.class);
        
        return http.build();
    }
    
    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }
}

2.3 JWT生成与验证工具类

@Component
public class JwtTokenProvider {
    
    private String secretKey = "mySecretKey12345678901234567890";
    private int validityInMilliseconds = 3600000; // 1 hour
    
    @PostConstruct
    protected void init() {
        secretKey = Base64.getEncoder().encodeToString(secretKey.getBytes());
    }
    
    public String createToken(String username, List<String> roles) {
        Claims claims = Jwts.claims().setSubject(username);
        claims.put("roles", roles);
        
        Date now = new Date();
        Date validity = new Date(now.getTime() + validityInMilliseconds);
        
        return Jwts.builder()
                .setClaims(claims)
                .setIssuedAt(now)
                .setExpiration(validity)
                .signWith(SignatureAlgorithm.HS256, secretKey)
                .compact();
    }
    
    public String getUsername(String token) {
        return Jwts.parser().setSigningKey(secretKey).parseClaimsJws(token).getBody().getSubject();
    }
    
    public boolean validateToken(String token) {
        try {
            Jwts.parser().setSigningKey(secretKey).parseClaimsJws(token);
            return true;
        } catch (JwtException | IllegalArgumentException e) {
            throw new CustomAuthenticationException("Expired or invalid JWT token");
        }
    }
}

2.4 JWT认证过滤器实现

@Component
public class JwtAuthenticationFilter extends OncePerRequestFilter {
    
    @Autowired
    private JwtTokenProvider tokenProvider;
    
    @Autowired
    private UserDetailsService userDetailsService;
    
    @Override
    protected void doFilterInternal(HttpServletRequest request, 
                                  HttpServletResponse response, 
                                  FilterChain filterChain) throws ServletException, IOException {
        
        String token = resolveToken(request);
        
        if (token != null && tokenProvider.validateToken(token)) {
            String username = tokenProvider.getUsername(token);
            UserDetails userDetails = userDetailsService.loadUserByUsername(username);
            
            UsernamePasswordAuthenticationToken authentication = 
                new UsernamePasswordAuthenticationToken(userDetails, null, userDetails.getAuthorities());
            
            SecurityContextHolder.getContext().setAuthentication(authentication);
        }
        
        filterChain.doFilter(request, response);
    }
    
    private String resolveToken(HttpServletRequest request) {
        String bearerToken = request.getHeader("Authorization");
        if (bearerToken != null && bearerToken.startsWith("Bearer ")) {
            return bearerToken.substring(7);
        }
        return null;
    }
}

OAuth2协议集成

3.1 OAuth2安全模型

OAuth2是一种开放的授权框架，允许第三方应用在用户授权的情况下访问资源。Spring Security 6.0提供了完整的OAuth2支持，包括：

OAuth2客户端支持
OAuth2服务端支持

资源服务器配置

3.2 OAuth2客户端配置

@Configuration
@EnableWebSecurity
public class OAuth2ClientConfig {
    
    @Bean
    public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
        http
            .oauth2Login(oauth2 -> oauth2
                .loginPage("/login")
                .defaultSuccessUrl("/dashboard")
                .failureUrl("/login?error=true")
                .authorizationEndpoint(authz -> authz
                    .baseUri("/oauth2/authorize")
                    .authorizationRequestRepository(cookieAuthorizationRequestRepository())
                )
                .redirectionEndpoint(redir -> redir
                    .baseUri("/oauth2/callback/*")
                )
                .userInfoEndpoint(userInfo -> userInfo
                    .userAuthoritiesMapper(userAuthoritiesMapper())
                )
                .successHandler(customOAuth2SuccessHandler())
            )
            .oauth2Client(oauth2 -> oauth2
                .clientRegistrationRepository(clientRegistrationRepository())
                .authorizedClientRepository(authorizedClientRepository())
            );
        
        return http.build();
    }
    
    @Bean
    public ClientRegistrationRepository clientRegistrationRepository() {
        return new InMemoryClientRegistrationRepository(googleClientRegistration());
    }
    
    @Bean
    public OAuth2AuthorizedClientRepository authorizedClientRepository() {
        return new InMemoryOAuth2AuthorizedClientRepository();
    }
    
    private ClientRegistration googleClientRegistration() {
        return ClientRegistration.withRegistrationId("google")
                .clientId("your-client-id")
                .clientSecret("your-client-secret")
                .clientAuthenticationMethod(ClientAuthenticationMethod.CLIENT_SECRET_BASIC)
                .authorizationGrantType(AuthorizationGrantType.AUTHORIZATION_CODE)
                .redirectUri("{baseUrl}/oauth2/callback/{registrationId}")
                .scope("openid", "profile", "email")
                .authorizationUri("https://accounts.google.com/o/oauth2/auth")
                .tokenUri("https://www.googleapis.com/oauth2/v4/token")
                .userInfoUri("https://www.googleapis.com/oauth2/v2/userinfo")
                .userNameAttributeName("sub")
                .clientName("Google")
                .build();
    }
}

3.3 自定义OAuth2成功处理器

@Component
public class CustomOAuth2SuccessHandler implements AuthenticationSuccessHandler {
    
    @Override
    public void onAuthenticationSuccess(HttpServletRequest request, 
                                       HttpServletResponse response,
                                       Authentication authentication) throws IOException, ServletException {
        
        OAuth2AuthenticationToken oauth2Token = (OAuth2AuthenticationToken) authentication;
        String provider = oauth2Token.getAuthorizedClientRegistrationId();
        
        // 获取用户信息
        OAuth2User oauth2User = authentication.getPrincipal();
        String email = (String) oauth2User.getAttributes().get("email");
        String name = (String) oauth2User.getAttributes().get("name");
        
        // 创建本地用户或更新用户信息
        // ... 用户管理逻辑
        
        // 重定向到用户主页
        response.sendRedirect("/dashboard");
    }
}

RBAC权限控制实现

4.1 RBAC基础概念

基于角色的访问控制（Role-Based Access Control, RBAC）是一种广泛使用的企业级权限管理模型。在RBAC中，权限与角色相关联，用户通过分配角色获得相应的权限。

4.2 权限管理实体设计

@Entity
@Table(name = "users")
public class User {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    
    @Column(unique = true, nullable = false)
    private String username;
    
    @Column(nullable = false)
    private String password;
    
    @Column(unique = true, nullable = false)
    private String email;
    
    @ManyToMany(fetch = FetchType.EAGER)
    @JoinTable(
        name = "user_roles",
        joinColumns = @JoinColumn(name = "user_id"),
        inverseJoinColumns = @JoinColumn(name = "role_id")
    )
    private Set<Role> roles = new HashSet<>();
    
    // getters and setters
}

@Entity
@Table(name = "roles")
public class Role {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    
    @Column(unique = true, nullable = false)
    private String name;
    
    @ManyToMany(mappedBy = "roles")
    private Set<User> users = new HashSet<>();
    
    @ManyToMany(fetch = FetchType.EAGER)
    @JoinTable(
        name = "role_permissions",
        joinColumns = @JoinColumn(name = "role_id"),
        inverseJoinColumns = @JoinColumn(name = "permission_id")
    )
    private Set<Permission> permissions = new HashSet<>();
    
    // getters and setters
}

@Entity
@Table(name = "permissions")
public class Permission {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    
    @Column(unique = true, nullable = false)
    private String name;
    
    @Column(nullable = false)
    private String description;
    
    // getters and setters
}

4.3 权限检查实现

@Component
public class PermissionEvaluator {
    
    @Autowired
    private UserRepository userRepository;
    
    public boolean hasPermission(Authentication authentication, String permission) {
        if (authentication == null || !(authentication instanceof UsernamePasswordAuthenticationToken)) {
            return false;
        }
        
        String username = authentication.getName();
        User user = userRepository.findByUsername(username);
        
        if (user == null) {
            return false;
        }
        
        return user.getRoles().stream()
                .flatMap(role -> role.getPermissions().stream())
                .anyMatch(p -> p.getName().equals(permission));
    }
    
    public boolean hasRole(Authentication authentication, String role) {
        if (authentication == null || !(authentication instanceof UsernamePasswordAuthenticationToken)) {
            return false;
        }
        
        String username = authentication.getName();
        User user = userRepository.findByUsername(username);
        
        if (user == null) {
            return false;
        }
        
        return user.getRoles().stream()
                .anyMatch(r -> r.getName().equals(role));
    }
}

@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
@PreAuthorize("@permissionEvaluator.hasPermission(authentication, #permission)")
public @interface HasPermission {
    String permission();
}

4.4 基于注解的权限控制

@RestController
@RequestMapping("/api/admin")
public class AdminController {
    
    @GetMapping("/users")
    @PreAuthorize("hasRole('ADMIN')")
    public List<User> getAllUsers() {
        // 实现逻辑
        return userService.getAllUsers();
    }
    
    @PostMapping("/users")
    @PreAuthorize("@permissionEvaluator.hasPermission(authentication, 'USER_CREATE')")
    public User createUser(@RequestBody User user) {
        // 实现逻辑
        return userService.createUser(user);
    }
    
    @DeleteMapping("/users/{id}")
    @PreAuthorize("hasRole('ADMIN') and @permissionEvaluator.hasPermission(authentication, 'USER_DELETE')")
    public ResponseEntity<?> deleteUser(@PathVariable Long id) {
        // 实现逻辑
        userService.deleteUser(id);
        return ResponseEntity.ok().build();
    }
}

安全头配置优化

5.1 安全头重要性

HTTP安全头是保护Web应用免受常见攻击的重要手段，包括XSS、点击劫持、数据泄露等。Spring Security 6.0提供了内置的安全头配置支持。

5.2 安全头配置实现

@Configuration
@EnableWebSecurity
public class SecurityHeadersConfig {
    
    @Bean
    public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
        http
            .headers(headers -> headers
                .frameOptions().deny()
                .contentTypeOptions().and()
                .xssProtection().and()
                .cacheControl().and()
                .httpStrictTransportSecurity().maxAgeInSeconds(31536000).includeSubdomains(true).preload(true)
                .and()
                .contentSecurityPolicy("default-src 'self'; script-src 'self' 'unsafe-inline'; style-src 'self' 'unsafe-inline'")
            )
            .csrf().disable()
            .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS);
        
        return http.build();
    }
}

5.3 自定义安全头配置

@Component
public class CustomSecurityHeadersFilter implements Filter {
    
    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
            throws IOException, ServletException {
        
        HttpServletResponse httpResponse = (HttpServletResponse) response;
        
        httpResponse.setHeader("X-Content-Type-Options", "nosniff");
        httpResponse.setHeader("X-Frame-Options", "DENY");
        httpResponse.setHeader("X-XSS-Protection", "1; mode=block");
        httpResponse.setHeader("Strict-Transport-Security", "max-age=31536000; includeSubDomains");
        httpResponse.setHeader("Referrer-Policy", "strict-origin-when-cross-origin");
        
        chain.doFilter(request, response);
    }
}

安全最佳实践

6.1 密码安全策略

@Configuration
public class PasswordSecurityConfig {
    
    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder(12); // 使用12轮加密
    }
    
    @Bean
    public PasswordValidationService passwordValidationService() {
        return new PasswordValidationService() {
            @Override
            public boolean isValid(String password) {
                // 密码强度检查
                if (password.length() < 8) return false;
                if (!password.matches(".*[0-9].*")) return false;
                if (!password.matches(".*[a-z].*")) return false;
                if (!password.matches(".*[A-Z].*")) return false;
                if (!password.matches(".*[!@#$%^&*()_+\\-=\\[\\]{};':\"\\\\|,.<>\\/?].*")) return false;
                return true;
            }
        };
    }
}

6.2 会话管理安全

@Bean
public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
    http
        .sessionManagement(session -> session
            .sessionCreationPolicy(SessionCreationPolicy.IF_REQUIRED)
            .maximumSessions(1)
            .maxSessionsPreventsLogin(false)
            .sessionRegistry(sessionRegistry())
        )
        .sessionFixation().migrateSession()
        .and()
        .logout(logout -> logout
            .logoutUrl("/logout")
            .logoutSuccessUrl("/login?logout")
            .invalidateHttpSession(true)
            .clearAuthentication(true)
            .deleteCookies("JSESSIONID")
        );
    
    return http.build();
}

@Bean
public SessionRegistry sessionRegistry() {
    return new SessionRegistryImpl();
}

6.3 异常处理机制

@ControllerAdvice
public class SecurityExceptionHandler {
    
    @ExceptionHandler(AuthenticationException.class)
    public ResponseEntity<ErrorResponse> handleAuthenticationException(AuthenticationException ex) {
        ErrorResponse error = new ErrorResponse("AUTHENTICATION_FAILED", ex.getMessage());
        return ResponseEntity.status(HttpStatus.UNAUTHORIZED).body(error);
    }
    
    @ExceptionHandler(AccessDeniedException.class)
    public ResponseEntity<ErrorResponse> handleAccessDeniedException(AccessDeniedException ex) {
        ErrorResponse error = new ErrorResponse("ACCESS_DENIED", "Access denied");
        return ResponseEntity.status(HttpStatus.FORBIDDEN).body(error);
    }
    
    @ExceptionHandler(InvalidBearerTokenException.class)
    public ResponseEntity<ErrorResponse> handleInvalidToken(InvalidBearerTokenException ex) {
        ErrorResponse error = new ErrorResponse("INVALID_TOKEN", "Invalid or expired token");
        return ResponseEntity.status(HttpStatus.UNAUTHORIZED).body(error);
    }
}

public class ErrorResponse {
    private String code;
    private String message;
    private long timestamp;
    
    public ErrorResponse(String code, String message) {
        this.code = code;
        this.message = message;
        this.timestamp = System.currentTimeMillis();
    }
    
    // getters and setters
}

    @EventListener
    public void handleLogout(LogoutSuccessEvent event) {
        logger.info("User logged out: {}", event.getAuthentication().getPrincipal());
    }
}

7.2 安全配置验证

@Component
public class SecurityConfigurationValidator {
    
    public void validateSecurityConfiguration() {
        // 检查是否启用了CSRF保护
        // 检查是否正确配置了安全头
        // 检查密码编码器强度
        // 检查会话管理配置
        // 检查权限控制策略
    }
}
