@Configuration
@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();
    }
}

OAuth2协议集成详解

2.1 OAuth2认证流程分析

OAuth2作为一种开放的授权框架，为应用提供了安全的授权机制。在Spring Security 6.0中，OAuth2集成主要支持以下几种模式：

授权码模式（Authorization Code）：适用于Web应用
隐式模式（Implicit）：适用于浏览器端应用
客户端凭证模式（Client Credentials）：适用于服务间通信
资源所有者密码凭证模式（Resource Owner Password Credentials）：适用于信任的应用

2.2 客户端配置实现

@Configuration
@EnableOAuth2Client
public class OAuth2ClientConfig {
    
    @Bean
    public ClientRegistrationRepository clientRegistrationRepository() {
        ClientRegistration clientRegistration = ClientRegistration.withRegistrationId("google")
            .clientId("your-client-id")
            .clientSecret("your-client-secret")
            .clientAuthenticationMethod(ClientAuthenticationMethod.CLIENT_SECRET_BASIC)
            .authorizationGrantType(AuthorizationGrantType.AUTHORIZATION_CODE)
            .redirectUri("{baseUrl}/login/oauth2/code/{registrationId}")
            .scope("openid", "profile", "email")
            .authorizationUri("https://accounts.google.com/o/oauth2/auth")
            .tokenUri("https://oauth2.googleapis.com/token")
            .userInfoUri("https://www.googleapis.com/oauth2/v2/userinfo")
            .userNameAttributeName("sub")
            .clientName("Google")
            .build();
            
        return new InMemoryClientRegistrationRepository(clientRegistration);
    }
    
    @Bean
    public OAuth2AuthorizedClientManager authorizedClientManager(
            ClientRegistrationRepository clientRegistrationRepository,
            OAuth2AuthorizedClientService authorizedClientService) {
        
        OAuth2AuthorizedClientManager authorizedClientManager = 
            new DefaultOAuth2AuthorizedClientManager(
                clientRegistrationRepository, authorizedClientService);
        
        authorizedClientManager.setAuthorizedClientProvider(
            new OAuth2AuthorizedClientProviderBuilder()
                .authorizationCode()
                .refreshToken()
                .clientCredentials()
                .build());
        
        return authorizedClientManager;
    }
}

2.3 资源服务器配置

@Configuration
@EnableWebSecurity
public class ResourceServerConfig {
    
    @Bean
    public SecurityFilterChain resourceServerFilterChain(HttpSecurity http) throws Exception {
        http
            .authorizeHttpRequests(authorize -> authorize
                .requestMatchers("/api/public/**").permitAll()
                .requestMatchers("/api/secure/**").authenticated()
                .anyRequest().authenticated()
            )
            .oauth2ResourceServer(oauth2 -> oauth2
                .jwt(jwt -> jwt.decoder(jwtDecoder()))
                .authenticationEntryPoint(new BearerTokenAuthenticationEntryPoint())
                .accessDeniedHandler(new BearerTokenAccessDeniedHandler())
            );
        return http.build();
    }
    
    @Bean
    public JwtDecoder jwtDecoder() {
        NimbusJwtDecoder jwtDecoder = new NimbusJwtDecoder(jwkSetUri());
        // 配置JWT验证器
        jwtDecoder.setJwtValidator(jwtValidator());
        return jwtDecoder;
    }
    
    private String jwkSetUri() {
        return "https://your-auth-server.com/.well-known/jwks.json";
    }
    
    private JwtValidator jwtValidator() {
        return new JwtValidator() {
            @Override
            public void validate(Jwt jwt) throws JwtValidationException {
                // 自定义JWT验证逻辑
                if (jwt.getExpiresAt().isBefore(Instant.now())) {
                    throw new JwtValidationException("Token has expired");
                }
                // 添加更多验证逻辑
            }
        };
    }
}

JWT令牌管理最佳实践

3.1 JWT令牌生成与解析

JWT（JSON Web Token）作为现代认证机制的核心组件，在Spring Security 6.0中得到了全面支持：

@Component
public class JwtTokenProvider {
    
    private final String secretKey = "your-secret-key-here";
    private final long validityInMilliseconds = 3600000; // 1小时
    
    @PostConstruct
    protected void init() {
        secretKey = Base64.getEncoder().encodeToString(secretKey.getBytes());
    }
    
    public String createToken(Authentication authentication) {
        UserDetails user = (UserDetails) authentication.getPrincipal();
        
        Date now = new Date();
        Date validity = new Date(now.getTime() + validityInMilliseconds);
        
        return Jwts.builder()
                .setSubject(user.getUsername())
                .claim("roles", user.getAuthorities())
                .setIssuedAt(now)
                .setExpiration(validity)
                .signWith(SignatureAlgorithm.HS512, secretKey)
                .compact();
    }
    
    public Authentication getAuthentication(String token) {
        Claims claims = Jwts.parser()
                .setSigningKey(secretKey)
                .parseClaimsJws(token)
                .getBody();
        
        Collection<? extends GrantedAuthority> authorities =
                Arrays.stream(claims.get("roles").toString().split(","))
                        .map(SimpleGrantedAuthority::new)
                        .collect(Collectors.toList());
        
        UserDetails principal = new User(claims.getSubject(), "", authorities);
        return new UsernamePasswordAuthenticationToken(principal, token, authorities);
    }
    
    public boolean validateToken(String token) {
        try {
            Jwts.parser().setSigningKey(secretKey).parseClaimsJws(token);
            return true;
        } catch (JwtException | IllegalArgumentException e) {
            return false;
        }
    }
}

3.2 JWT令牌刷新机制

@RestController
@RequestMapping("/auth")
public class AuthController {
    
    @Autowired
    private JwtTokenProvider tokenProvider;
    
    @PostMapping("/refresh")
    public ResponseEntity<?> refreshToken(@RequestHeader("Authorization") String token) {
        try {
            if (token != null && token.startsWith("Bearer ")) {
                String refreshToken = token.substring(7);
                String username = tokenProvider.getUsernameFromToken(refreshToken);
                
                if (username != null && tokenProvider.validateToken(refreshToken)) {
                    // 生成新的访问令牌
                    String newToken = tokenProvider.createToken(username);
                    return ResponseEntity.ok(new JwtResponse(newToken));
                }
            }
            return ResponseEntity.status(HttpStatus.UNAUTHORIZED).build();
        } catch (Exception e) {
            return ResponseEntity.status(HttpStatus.UNAUTHORIZED).build();
        }
    }
    
    @Data
    @AllArgsConstructor
    public static class JwtResponse {
        private String token;
        private String type = "Bearer";
    }
}

3.3 JWT安全配置

@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()
                .requestMatchers("/api/public/**").permitAll()
                .anyRequest().authenticated()
            )
            .addFilterBefore(new JwtAuthenticationFilter(), UsernamePasswordAuthenticationFilter.class)
            .exceptionHandling().and()
            .headers().frameOptions().sameOrigin();
        
        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;
    }
}

RBAC权限控制体系

4.1 基于角色的访问控制实现

RBAC（Role-Based Access Control）是企业应用中最常见的权限控制模型。Spring Security 6.0提供了完善的RBAC支持：

@Service
public class UserService {
    
    @Autowired
    private UserRepository userRepository;
    
    @Autowired
    private RoleRepository roleRepository;
    
    @Transactional
    public User createUser(String username, String password, List<String> roles) {
        User user = new User();
        user.setUsername(username);
        user.setPassword(passwordEncoder.encode(password));
        user.setEnabled(true);
        
        Set<Role> userRoles = new HashSet<>();
        for (String roleName : roles) {
            Role role = roleRepository.findByName(roleName)
                .orElseThrow(() -> new RuntimeException("Role not found: " + roleName));
            userRoles.add(role);
        }
        user.setRoles(userRoles);
        
        return userRepository.save(user);
    }
    
    @PreAuthorize("hasRole('ADMIN')")
    public List<User> getAllUsers() {
        return userRepository.findAll();
    }
    
    @PreAuthorize("hasAnyRole('ADMIN', 'USER')")
    public User getUserById(Long id) {
        return userRepository.findById(id)
            .orElseThrow(() -> new RuntimeException("User not found"));
    }
}

4.2 自定义权限注解

@Target({ElementType.METHOD, ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
@PreAuthorize("@permissionEvaluator.hasPermission(authentication, #resource, 'READ')")
public @interface ReadPermission {
    String resource() default "";
}

@Target({ElementType.METHOD, ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
@PreAuthorize("@permissionEvaluator.hasPermission(authentication, #resource, 'WRITE')")
public @interface WritePermission {
    String resource() default "";
}

@Component
public class CustomPermissionEvaluator implements PermissionEvaluator {
    
    @Override
    public boolean hasPermission(Authentication authentication, Object targetDomainObject, Object permission) {
        if (authentication == null || targetDomainObject == null || !(permission instanceof String)) {
            return false;
        }
        
        String targetType = targetDomainObject.getClass().getSimpleName().toUpperCase();
        return hasPrivilege(authentication, targetType, permission.toString().toUpperCase());
    }
    
    @Override
    public boolean hasPermission(Authentication authentication, Serializable targetId, String targetType, Object permission) {
        if (authentication == null || targetId == null || !(permission instanceof String)) {
            return false;
        }
        
        String target = targetId.toString().toUpperCase();
        return hasPrivilege(authentication, targetType.toUpperCase(), permission.toString().toUpperCase());
    }
    
    private boolean hasPrivilege(Authentication authentication, String targetType, String permission) {
        for (GrantedAuthority grantedAuth : authentication.getAuthorities()) {
            String authority = grantedAuth.getAuthority();
            if (authority.startsWith(targetType)) {
                return authority.contains(permission);
            }
        }
        return false;
    }
}

4.3 权限控制配置

@Configuration
@EnableGlobalMethodSecurity(prePostEnabled = true, securedEnabled = true)
public class MethodSecurityConfig {
    
    @Bean
    public MethodSecurityExpressionHandler methodSecurityExpressionHandler() {
        DefaultMethodSecurityExpressionHandler expressionHandler = 
            new DefaultMethodSecurityExpressionHandler();
        expressionHandler.setPermissionEvaluator(new CustomPermissionEvaluator());
        return expressionHandler;
    }
    
    @Bean
    public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
        http
            .authorizeHttpRequests(authz -> authz
                .requestMatchers("/admin/**").hasRole("ADMIN")
                .requestMatchers("/user/**").hasAnyRole("USER", "ADMIN")
                .requestMatchers("/public/**").permitAll()
                .anyRequest().authenticated()
            )
            .formLogin(form -> form
                .loginPage("/login")
                .permitAll()
                .defaultSuccessUrl("/dashboard")
                .failureUrl("/login?error=true")
            )
            .logout(logout -> logout
                .logoutUrl("/logout")
                .logoutSuccessUrl("/login?logout=true")
                .permitAll()
            );
        return http.build();
    }
}

安全加固实践

5.1 密码安全配置

@Configuration
public class PasswordConfig {
    
    @Bean
    public PasswordEncoder passwordEncoder() {
        // Spring Security 6.0默认使用BCryptPasswordEncoder
        return new BCryptPasswordEncoder(12); // 12是成本因子，值越大越安全
    }
    
    @Bean
    public DelegatingPasswordEncoder passwordEncoder() {
        Map<String, PasswordEncoder> encoders = new HashMap<>();
        encoders.put("bcrypt", new BCryptPasswordEncoder(12));
        encoders.put("pbkdf2", new Pbkdf2PasswordEncoder());
        encoders.put("scrypt", new SCryptPasswordEncoder());
        
        DelegatingPasswordEncoder passwordEncoder = new DelegatingPasswordEncoder("bcrypt", encoders);
        passwordEncoder.setDefaultPasswordEncoderForMatches(new BCryptPasswordEncoder(12));
        return passwordEncoder;
    }
}

5.2 安全响应头配置

@Bean
public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
    http
        .headers(headers -> headers
            .frameOptions().deny()
            .contentTypeOptions().and()
            .httpStrictTransportSecurity(hsts -> hsts
                .maxAgeInSeconds(31536000)
                .includeSubdomains(true)
                .preload(true)
            )
            .xssProtection().and()
            .cacheControl().and()
            .contentTypeOptions()
        )
        .sessionManagement(session -> session
            .sessionCreationPolicy(SessionCreationPolicy.IF_REQUIRED)
            .maximumSessions(1)
            .maxSessionsPreventsLogin(false)
        );
    return http.build();
}

5.3 安全审计与监控

@Component
public class SecurityAuditLogger {
    
    private static final Logger logger = LoggerFactory.getLogger(SecurityAuditLogger.class);
    
    @EventListener
    public void handleAuthenticationSuccess(AuthenticationSuccessEvent event) {
        Authentication authentication = event.getAuthentication();
        logger.info("Authentication successful for user: {}", authentication.getName());
    }
    
    @EventListener
    public void handleAuthenticationFailure(AuthenticationFailureEvent event) {
        Authentication authentication = event.getAuthentication();
        logger.warn("Authentication failed for user: {}", authentication.getName());
    }
    
    @EventListener
    public void handleLogout(LogoutSuccessEvent event) {
        Authentication authentication = event.getAuthentication();
        if (authentication != null) {
            logger.info("User logged out: {}", authentication.getName());
        }
    }
}

性能优化与最佳实践

6.1 缓存优化

@Configuration
public class CacheConfig {
    
    @Bean
    public CacheManager cacheManager() {
        CaffeineCacheManager cacheManager = new CaffeineCacheManager();
        cacheManager.setCaffeine(Caffeine.newBuilder()
            .maximumSize(1000)
            .expireAfterWrite(30, TimeUnit.MINUTES)
            .recordStats());
        return cacheManager;
    }
    
    @Cacheable(value = "jwtTokens", key = "#token")
    public String getJwtClaims(String token) {
        // 从缓存中获取JWT声明
        return jwtDecoder.decode(token).getClaims().toString();
    }
}

6.2 并发安全控制

@Component
public class ConcurrentAccessControl {
    
    private final Map<String, AtomicInteger> userAccessCount = new ConcurrentHashMap<>();
    private final int maxConcurrentAccess = 5;
    
    public boolean canAccess(String username) {
        AtomicInteger count = userAccessCount.computeIfAbsent(username, k -> new AtomicInteger(0));
        int currentCount = count.get();
        
        if (currentCount >= maxConcurrentAccess) {
            return false;
        }
        
        return count.compareAndSet(currentCount, currentCount + 1);
    }
    
    public void releaseAccess(String username) {
        AtomicInteger count = userAccessCount.get(username);
        if (count != null) {
            count.decrementAndGet();
        }
    }
}
