@EnableWebSecurity
public class SecurityConfig {
    
    @Bean
    public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
        http
            .authorizeHttpRequests(authz -> authz
                .requestMatchers("/public/**").permitAll()
                .anyRequest().authenticated()
            )
            .oauth2ResourceServer(oauth2 -> oauth2
                .jwt(jwt -> jwt.decoder(jwtDecoder()))
            );
        return http.build();
    }
}

2. OAuth2.0支持增强

新版框架对OAuth2.0协议的支持更加完善，包括Authorization Server、Resource Server等核心组件的标准化实现。

3. JWT集成原生化

Spring Security 6.0将JWT处理能力深度集成到框架中，提供了更加简洁的配置方式和更强的安全性保障。

OAuth2.0授权服务器配置详解

授权服务器架构设计

在Spring Security 6.0中，OAuth2.0授权服务器的配置需要遵循新的安全架构模式。授权服务器主要负责令牌的颁发、验证以及用户身份认证等核心功能。

核心配置实现

@Configuration
@EnableAuthorizationServer
public class AuthorizationServerConfig {
    
    @Bean
    public RegisteredClientRepository registeredClientRepository() {
        RegisteredClient registeredClient = RegisteredClient.withId(UUID.randomUUID().toString())
            .clientId("client-app")
            .clientSecret("{noop}secret")
            .authorizationGrantType(AuthorizationGrantType.AUTHORIZATION_CODE)
            .authorizationGrantType(AuthorizationGrantType.REFRESH_TOKEN)
            .authorizationGrantType(AuthorizationGrantType.CLIENT_CREDENTIALS)
            .redirectUri("http://localhost:8080/login/oauth2/code/client-app")
            .scope(OidcScopes.OPENID)
            .scope("read")
            .scope("write")
            .clientSettings(ClientSettings.builder()
                .requireAuthorizationConsent(true)
                .build())
            .build();
        
        return new InMemoryRegisteredClientRepository(registeredClient);
    }
    
    @Bean
    public JWKSetExporter jwkSetExporter() {
        RSAKey rsaKey = this.generateRsa();
        JWKSet jwkSet = new JWKSet(rsaKey);
        return new JWKSetExporter(jwkSet);
    }
    
    private RSAKey generateRsa() {
        KeyPair keyPair = KeyGeneratorUtils.generateRsaKey();
        RSAPublicKey publicKey = (RSAPublicKey) keyPair.getPublic();
        RSAPrivateKey privateKey = (RSAPrivateKey) keyPair.getPrivate();
        
        return new RSAKey.Builder(publicKey)
            .privateKey(privateKey)
            .keyID(UUID.randomUUID().toString())
            .build();
    }
}

授权流程完整实现

@RestController
public class AuthorizationController {
    
    @GetMapping("/oauth2/authorize")
    public String authorize(
            @RequestParam String response_type,
            @RequestParam String client_id,
            @RequestParam String redirect_uri,
            @RequestParam(required = false) String scope,
            @RequestParam(required = false) String state,
            HttpServletRequest request) {
        
        // 验证客户端
        if (!isValidClient(client_id)) {
            return "Invalid client";
        }
        
        // 检查用户是否已登录
        Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
        if (authentication == null || !authentication.isAuthenticated()) {
            // 重定向到登录页面
            return "redirect:/login?oauth2=true&client_id=" + client_id;
        }
        
        // 生成授权码
        String authorizationCode = generateAuthorizationCode();
        
        // 存储授权码（实际应用中应使用数据库）
        storeAuthorizationCode(authorizationCode, client_id, authentication.getName());
        
        // 重定向回客户端
        return "redirect:" + redirect_uri + "?code=" + authorizationCode + "&state=" + state;
    }
    
    private boolean isValidClient(String clientId) {
        // 实现客户端验证逻辑
        return true;
    }
    
    private String generateAuthorizationCode() {
        return UUID.randomUUID().toString();
    }
    
    private void storeAuthorizationCode(String code, String clientId, String username) {
        // 存储授权码逻辑
    }
}

JWT令牌生成与验证机制

JWT配置基础

在Spring Security 6.0中，JWT令牌的生成和验证通过JwtDecoder和JwtEncoder来实现。这种设计使得令牌处理更加灵活和安全。

@Configuration
public class JwtConfig {
    
    @Bean
    public JwtDecoder jwtDecoder() {
        return new NimbusJwtDecoder(jwtProcessor());
    }
    
    @Bean
    public JwtEncoder jwtEncoder() {
        JWKSet jwkSet = loadJwkSet();
        RSAKey rsaKey = jwkSet.getKeyByKeyId("key-id");
        RSAPublicKey publicKey = rsaKey.toRSAPublicKey();
        RSAPrivateKey privateKey = rsaKey.toRSAPrivateKey();
        
        JWKSource<SecurityContext> jwkSource = new ImmutableJWKSet<>(jwkSet);
        return new NimbusJwtEncoder(jwkSource);
    }
    
    private RSAKey loadJwkSet() {
        // 加载JWK集的逻辑
        return null;
    }
    
    private JwtProcessor<SecurityContext> jwtProcessor() {
        // 配置JWT处理器
        return null;
    }
}

自定义JWT令牌生成器

@Component
public class CustomJwtTokenGenerator {
    
    private final JwtEncoder jwtEncoder;
    private final JwtDecoder jwtDecoder;
    
    public CustomJwtTokenGenerator(JwtEncoder jwtEncoder, JwtDecoder jwtDecoder) {
        this.jwtEncoder = jwtEncoder;
        this.jwtDecoder = jwtDecoder;
    }
    
    public String generateToken(Authentication authentication, List<String> scopes) {
        Instant now = Instant.now();
        
        // 设置JWT声明
        JwtClaimsSet claims = JwtClaimsSet.builder()
            .issuer("https://auth-server.com")
            .issuedAt(now)
            .expiresAt(now.plus(1, ChronoUnit.HOURS))
            .subject(authentication.getName())
            .claim("scope", scopes)
            .claim("roles", getRolesFromAuthentication(authentication))
            .build();
        
        // 生成JWT令牌
        return jwtEncoder.encode(JwtEncoderParameters.from(claims)).getTokenValue();
    }
    
    public Jwt decodeToken(String token) {
        try {
            return jwtDecoder.decode(token);
        } catch (JwtException e) {
            throw new BadCredentialsException("Invalid JWT token", e);
        }
    }
    
    private List<String> getRolesFromAuthentication(Authentication authentication) {
        return authentication.getAuthorities().stream()
            .map(GrantedAuthority::getAuthority)
            .collect(Collectors.toList());
    }
}

JWT令牌验证过滤器

@Component
public class JwtAuthenticationFilter extends OncePerRequestFilter {
    
    private final JwtDecoder jwtDecoder;
    private final UserDetailsService userDetailsService;
    
    public JwtAuthenticationFilter(JwtDecoder jwtDecoder, UserDetailsService userDetailsService) {
        this.jwtDecoder = jwtDecoder;
        this.userDetailsService = userDetailsService;
    }
    
    @Override
    protected void doFilterInternal(HttpServletRequest request, 
                                  HttpServletResponse response, 
                                  FilterChain filterChain) throws ServletException, IOException {
        
        String authHeader = request.getHeader("Authorization");
        
        if (authHeader == null || !authHeader.startsWith("Bearer ")) {
            filterChain.doFilter(request, response);
            return;
        }
        
        try {
            String token = authHeader.substring(7);
            Jwt jwt = jwtDecoder.decode(token);
            
            String username = jwt.getSubject();
            Collection<GrantedAuthority> authorities = extractAuthorities(jwt);
            
            UsernamePasswordAuthenticationToken authentication = 
                new UsernamePasswordAuthenticationToken(username, null, authorities);
            
            SecurityContextHolder.getContext().setAuthentication(authentication);
        } catch (JwtException e) {
            response.setStatus(HttpStatus.UNAUTHORIZED.value());
            response.getWriter().write("Invalid token");
            return;
        }
        
        filterChain.doFilter(request, response);
    }
    
    private Collection<GrantedAuthority> extractAuthorities(Jwt jwt) {
        List<String> scopes = jwt.getClaimAsStringList("scope");
        if (scopes == null) {
            return Collections.emptyList();
        }
        
        return scopes.stream()
            .map(SimpleGrantedAuthority::new)
            .collect(Collectors.toList());
    }
}

RBAC权限控制实现

权限模型设计

基于Spring Security 6.0的RBAC（Role-Based Access Control）权限控制需要结合JWT令牌中的角色信息来实现细粒度的访问控制。

@Configuration
@EnableMethodSecurity(prePostEnabled = true)
public class MethodSecurityConfig {
    
    @Bean
    public MethodSecurityExpressionHandler methodSecurityExpressionHandler() {
        DefaultMethodSecurityExpressionHandler handler = new DefaultMethodSecurityExpressionHandler();
        handler.setPermissionEvaluator(new CustomPermissionEvaluator());
        return handler;
    }
}

@Component
public class CustomPermissionEvaluator implements PermissionEvaluator {
    
    @Override
    public boolean hasPermission(Authentication authentication, Object targetDomainObject, Object permission) {
        if (authentication == null || !(targetDomainObject instanceof String)) {
            return false;
        }
        
        String targetType = targetDomainObject.toString().toLowerCase();
        String userRole = getUserRole(authentication);
        
        // 基于角色的权限检查
        return checkPermissionByRole(userRole, targetType, permission.toString());
    }
    
    @Override
    public boolean hasPermission(Authentication authentication, Serializable targetId, String targetType, Object permission) {
        if (authentication == null || !(targetId instanceof String)) {
            return false;
        }
        
        String userRole = getUserRole(authentication);
        return checkPermissionByRole(userRole, targetType.toLowerCase(), permission.toString());
    }
    
    private String getUserRole(Authentication authentication) {
        Collection<? extends GrantedAuthority> authorities = authentication.getAuthorities();
        for (GrantedAuthority authority : authorities) {
            if (authority.getAuthority().startsWith("ROLE_")) {
                return authority.getAuthority().substring(5); // 移除ROLE_前缀
            }
        }
        return "USER";
    }
    
    private boolean checkPermissionByRole(String userRole, String targetType, String permission) {
        Map<String, Set<String>> rolePermissions = getRolePermissions();
        Set<String> permissions = rolePermissions.get(userRole);
        
        if (permissions == null) {
            return false;
        }
        
        return permissions.contains(targetType + ":" + permission);
    }
    
    private Map<String, Set<String>> getRolePermissions() {
        // 配置角色权限映射
        Map<String, Set<String>> rolePermissions = new HashMap<>();
        
        rolePermissions.put("ADMIN", Set.of(
            "user:read", "user:write", "user:delete",
            "role:read", "role:write"
        ));
        
        rolePermissions.put("USER", Set.of(
            "user:read",
            "profile:read", "profile:write"
        ));
        
        return rolePermissions;
    }
}

基于注解的权限控制

@RestController
@RequestMapping("/api")
public class UserController {
    
    @GetMapping("/users")
    @PreAuthorize("hasRole('ADMIN')")
    public List<User> getAllUsers() {
        // 只有ADMIN角色可以访问
        return userService.getAllUsers();
    }
    
    @GetMapping("/users/{id}")
    @PreAuthorize("@permissionEvaluator.hasPermission(authentication, #id, 'user', 'read')")
    public User getUserById(@PathVariable Long id) {
        // 基于自定义权限评估器的访问控制
        return userService.getUserById(id);
    }
    
    @PostMapping("/users")
    @PreAuthorize("hasRole('ADMIN') and hasPermission('user', 'write')")
    public User createUser(@RequestBody User user) {
        // 需要ADMIN角色和写权限
        return userService.createUser(user);
    }
    
    @PutMapping("/users/{id}")
    @PreAuthorize("hasRole('ADMIN') or #userId == authentication.principal.id")
    public User updateUser(@PathVariable Long id, @RequestBody User user) {
        // ADMIN可以更新所有用户，普通用户只能更新自己的信息
        return userService.updateUser(id, user);
    }
}

安全配置最佳实践

综合安全配置示例

@Configuration
@EnableWebSecurity
public class SecurityConfiguration {
    
    @Bean
    public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
        http
            .authorizeHttpRequests(authz -> authz
                .requestMatchers("/public/**").permitAll()
                .requestMatchers("/api/public/**").permitAll()
                .requestMatchers("/oauth2/**").permitAll()
                .anyRequest().authenticated()
            )
            .oauth2ResourceServer(oauth2 -> oauth2
                .jwt(jwt -> jwt.decoder(jwtDecoder()))
            )
            .sessionManagement(session -> session
                .sessionCreationPolicy(SessionCreationPolicy.STATELESS)
            )
            .cors(cors -> cors.configurationSource(corsConfigurationSource()))
            .csrf(csrf -> csrf.disable());
        
        return http.build();
    }
    
    @Bean
    public CorsConfigurationSource corsConfigurationSource() {
        CorsConfiguration configuration = new CorsConfiguration();
        configuration.setAllowedOriginPatterns(Arrays.asList("*"));
        configuration.setAllowedMethods(Arrays.asList("GET", "POST", "PUT", "DELETE"));
        configuration.setAllowedHeaders(Arrays.asList("*"));
        configuration.setAllowCredentials(true);
        
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", configuration);
        return source;
    }
    
    @Bean
    public JwtDecoder jwtDecoder() {
        // 配置JWT解码器
        return new NimbusJwtDecoder(jwtProcessor());
    }
    
    private JwtProcessor<SecurityContext> jwtProcessor() {
        // 配置JWT处理器
        return null;
    }
}

安全头配置

@Component
public class SecurityHeadersConfig {
    
    @Bean
    public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
        http.headers(headers -> headers
            .frameOptions(frameOptions -> frameOptions.deny())
            .contentTypeOptions(contentTypeOptions -> contentTypeOptions.disable())
            .httpStrictTransportSecurity(hsts -> hsts
                .maxAgeInSeconds(31536000)
                .includeSubdomains(true)
                .preload(true)
            )
            .xssProtection(xss -> xss.block(true))
        );
        
        return http.build();
    }
}

性能优化与监控

JWT令牌缓存机制

@Component
public class JwtCacheManager {
    
    private final Cache<String, Jwt> jwtCache;
    
    public JwtCacheManager() {
        this.jwtCache = Caffeine.newBuilder()
            .maximumSize(1000)
            .expireAfterWrite(Duration.ofMinutes(30))
            .build();
    }
    
    public void put(String token, Jwt jwt) {
        jwtCache.put(token, jwt);
    }
    
    public Optional<Jwt> get(String token) {
        return Optional.ofNullable(jwtCache.getIfPresent(token));
    }
    
    public void invalidate(String token) {
        jwtCache.invalidate(token);
    }
}

安全审计日志

@Component
public class SecurityAuditLogger {
    
    private static final Logger logger = LoggerFactory.getLogger(SecurityAuditLogger.class);
    
    public void logAuthenticationSuccess(String username, String ipAddress) {
        logger.info("Successful authentication for user: {}, IP: {}", username, ipAddress);
    }
    
    public void logAuthenticationFailure(String username, String ipAddress) {
        logger.warn("Failed authentication attempt for user: {}, IP: {}", username, ipAddress);
    }
    
    public void logAuthorizationSuccess(String username, String resource, String action) {
        logger.info("Successful authorization for user: {}, resource: {}, action: {}", 
                   username, resource, action);
    }
    
    public void logAuthorizationFailure(String username, String resource, String action) {
        logger.warn("Failed authorization attempt for user: {}, resource: {}, action: {}", 
                   username, resource, action);
    }
}
