OAuth2授权框架详解

OAuth2基础概念

OAuth2是一种开放的授权标准，允许第三方应用在用户授权的情况下访问资源服务器上的资源。在Spring Security 6.0中，OAuth2支持得到了全面增强。

客户端配置

@Configuration
@EnableOAuth2Client
public class OAuth2ClientConfig {
    
    @Bean
    public ClientRegistrationRepository clientRegistrationRepository() {
        ClientRegistration clientRegistration = ClientRegistration.withRegistrationId("google")
            .clientId("your-client-id")
            .clientSecret("your-client-secret")
            .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")
            .scope("openid", "profile", "email")
            .redirectUri("{baseUrl}/login/oauth2/code/{registrationId}")
            .build();
            
        return new InMemoryClientRegistrationRepository(clientRegistration);
    }
    
    @Bean
    public OAuth2AuthorizedClientManager authorizedClientManager(
            ClientRegistrationRepository clientRegistrationRepository,
            OAuth2AuthorizedClientService authorizedClientService) {
        
        OAuth2AuthorizedClientManager authorizedClientManager = 
            new DefaultOAuth2AuthorizedClientManager(
                clientRegistrationRepository, authorizedClientService);
        
        return authorizedClientManager;
    }
}

服务器端配置

@Configuration
@EnableWebSecurity
public class OAuth2ServerConfig {
    
    @Bean
    public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
        http
            .authorizeHttpRequests(authorize -> authorize
                .requestMatchers("/oauth2/**").permitAll()
                .anyRequest().authenticated()
            )
            .oauth2ResourceServer(oauth2 -> oauth2
                .jwt(jwt -> jwt.decoder(jwtDecoder()))
            )
            .oauth2Login(oauth2 -> oauth2
                .loginPage("/login")
                .defaultSuccessUrl("/dashboard")
            );
        
        return http.build();
    }
    
    @Bean
    public JwtDecoder jwtDecoder() {
        NimbusJwtDecoder jwtDecoder = new NimbusJwtDecoder(jwkSetUri());
        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().before(new Date())) {
                    throw new JwtValidationException("Token has expired");
                }
            }
        };
    }
}

JWT令牌生成与验证

JWT配置基础

@Configuration
public class JwtConfig {
    
    @Value("${jwt.secret}")
    private String secret;
    
    @Value("${jwt.expiration}")
    private Long expiration;
    
    @Bean
    public JwtDecoder jwtDecoder() {
        return new NimbusJwtDecoder(jwtProcessor());
    }
    
    @Bean
    public JwtProcessor<SecurityContext> jwtProcessor() {
        // 创建JWT处理器
        JWKSet jwkSet = loadJwkSet();
        JWKSecurityContextJwsKeySelector<SecurityContext> keySelector = 
            new JWKSecurityContextJwsKeySelector<>(JWSAlgorithm.RS256, jwkSet);
        
        DefaultJWTProcessor<SecurityContext> jwtProcessor = 
            new DefaultJWTProcessor<>(keySelector);
        
        jwtProcessor.setJWTClaimsSetVerifier(new NoOpJWTClaimsSetVerifier<>());
        jwtProcessor.setJWSTokenVerifier(new DefaultJWSTokenVerifier<>());
        
        return jwtProcessor;
    }
    
    private JWKSet loadJwkSet() {
        // 从配置文件或数据库加载JWK Set
        return new JWKSet();
    }
}

JWT令牌生成器

@Component
public class JwtTokenGenerator {
    
    private final String secret;
    private final Long expiration;
    
    public JwtTokenGenerator(@Value("${jwt.secret}") String secret,
                           @Value("${jwt.expiration}") Long expiration) {
        this.secret = secret;
        this.expiration = expiration;
    }
    
    public String generateToken(UserDetails userDetails) {
        Date now = new Date();
        Date expiryDate = new Date(now.getTime() + expiration * 1000);
        
        return Jwts.builder()
            .setSubject(userDetails.getUsername())
            .setIssuedAt(new Date())
            .setExpiration(expiryDate)
            .claim("authorities", userDetails.getAuthorities().stream()
                .map(GrantedAuthority::getAuthority)
                .collect(Collectors.toList()))
            .signWith(SignatureAlgorithm.HS512, secret)
            .compact();
    }
    
    public String generateRefreshToken(UserDetails userDetails) {
        Date now = new Date();
        Date expiryDate = new Date(now.getTime() + 24 * 60 * 60 * 1000); // 24小时
        
        return Jwts.builder()
            .setSubject(userDetails.getUsername())
            .setIssuedAt(new Date())
            .setExpiration(expiryDate)
            .signWith(SignatureAlgorithm.HS512, secret)
            .compact();
    }
    
    public boolean validateToken(String token) {
        try {
            Jwts.parser().setSigningKey(secret).parseClaimsJws(token);
            return true;
        } catch (SignatureException e) {
            System.out.println("Invalid JWT signature");
        } catch (MalformedJwtException e) {
            System.out.println("Invalid JWT token");
        } catch (ExpiredJwtException e) {
            System.out.println("JWT token expired");
        } catch (UnsupportedJwtException e) {
            System.out.println("JWT token is unsupported");
        } catch (IllegalArgumentException e) {
            System.out.println("JWT claims string is empty");
        }
        return false;
    }
    
    public String getUsernameFromToken(String token) {
        return Jwts.parser().setSigningKey(secret).parseClaimsJws(token)
            .getBody().getSubject();
    }
}

JWT过滤器实现

@Component
public class JwtAuthenticationFilter extends OncePerRequestFilter {
    
    @Autowired
    private JwtTokenGenerator jwtTokenGenerator;
    
    @Autowired
    private UserDetailsService userDetailsService;
    
    @Override
    protected void doFilterInternal(HttpServletRequest request, 
                                  HttpServletResponse response, 
                                  FilterChain filterChain) throws ServletException, IOException {
        
        String requestTokenHeader = request.getHeader("Authorization");
        
        String username = null;
        String jwtToken = null;
        
        if (requestTokenHeader != null && requestTokenHeader.startsWith("Bearer ")) {
            jwtToken = requestTokenHeader.substring(7);
            try {
                username = jwtTokenGenerator.getUsernameFromToken(jwtToken);
            } catch (IllegalArgumentException e) {
                System.out.println("Unable to get JWT Token");
            } catch (Exception e) {
                System.out.println("JWT Token has expired");
            }
        }
        
        if (username != null && SecurityContextHolder.getContext().getAuthentication() == null) {
            UserDetails userDetails = this.userDetailsService.loadUserByUsername(username);
            
            if (jwtTokenGenerator.validateToken(jwtToken, userDetails)) {
                UsernamePasswordAuthenticationToken usernamePasswordAuthenticationToken = 
                    new UsernamePasswordAuthenticationToken(
                        userDetails, null, userDetails.getAuthorities());
                usernamePasswordAuthenticationToken.setDetails(
                    new WebAuthenticationDetailsSource().buildDetails(request));
                SecurityContextHolder.getContext().setAuthentication(usernamePasswordAuthenticationToken);
            }
        }
        filterChain.doFilter(request, response);
    }
}

RBAC权限控制实现

权限模型设计

@Entity
@Table(name = "roles")
public class Role {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    
    @Column(unique = true)
    private String name;
    
    @ManyToMany(mappedBy = "roles")
    private Set<User> users;
    
    // getters and setters
}

@Entity
@Table(name = "permissions")
public class Permission {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    
    @Column(unique = true)
    private String name;
    
    @ManyToMany
    @JoinTable(
        name = "permission_role",
        joinColumns = @JoinColumn(name = "permission_id"),
        inverseJoinColumns = @JoinColumn(name = "role_id")
    )
    private Set<Role> roles;
    
    // getters and setters
}

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

权限验证服务

@Service
public class PermissionService {
    
    @Autowired
    private UserRepository userRepository;
    
    @Autowired
    private RoleRepository roleRepository;
    
    @Autowired
    private PermissionRepository permissionRepository;
    
    public boolean hasPermission(String username, String permissionName) {
        User user = userRepository.findByUsername(username);
        if (user == null) {
            return false;
        }
        
        Set<Role> roles = user.getRoles();
        for (Role role : roles) {
            Set<Permission> permissions = role.getPermissions();
            for (Permission permission : permissions) {
                if (permission.getName().equals(permissionName)) {
                    return true;
                }
            }
        }
        return false;
    }
    
    public boolean hasAnyPermission(String username, Collection<String> permissionNames) {
        User user = userRepository.findByUsername(username);
        if (user == null) {
            return false;
        }
        
        Set<Role> roles = user.getRoles();
        for (Role role : roles) {
            Set<Permission> permissions = role.getPermissions();
            for (Permission permission : permissions) {
                if (permissionNames.contains(permission.getName())) {
                    return true;
                }
            }
        }
        return false;
    }
    
    public boolean hasRole(String username, String roleName) {
        User user = userRepository.findByUsername(username);
        if (user == null) {
            return false;
        }
        
        Set<Role> roles = user.getRoles();
        for (Role role : roles) {
            if (role.getName().equals(roleName)) {
                return true;
            }
        }
        return false;
    }
}

基于注解的权限控制

@Target({ElementType.METHOD, ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
@PreAuthorize("@permissionService.hasPermission(principal.username, 'READ_USER')")
public @interface RequireReadUserPermission {
}

@Target({ElementType.METHOD, ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
@PreAuthorize("@permissionService.hasRole(principal.username, 'ADMIN')")
public @interface RequireAdminRole {
}

@RestController
@RequestMapping("/api/users")
public class UserController {
    
    @GetMapping("/{id}")
    @RequireReadUserPermission
    public ResponseEntity<User> getUser(@PathVariable Long id) {
        // 实现获取用户逻辑
        return ResponseEntity.ok(userService.findById(id));
    }
    
    @DeleteMapping("/{id}")
    @RequireAdminRole
    public ResponseEntity<Void> deleteUser(@PathVariable Long id) {
        // 实现删除用户逻辑
        userService.deleteById(id);
        return ResponseEntity.noContent().build();
    }
}

安全配置最佳实践

完整的安全配置类

@Configuration
@EnableWebSecurity
@EnableMethodSecurity(prePostEnabled = true)
public class SecurityConfig {
    
    @Autowired
    private JwtAuthenticationFilter jwtAuthenticationFilter;
    
    @Bean
    public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
        http
            .csrf(csrf -> csrf.disable())
            .cors(cors -> cors.configurationSource(corsConfigurationSource()))
            .sessionManagement(session -> session
                .sessionCreationPolicy(SessionCreationPolicy.STATELESS)
            )
            .authorizeHttpRequests(authz -> authz
                .requestMatchers("/api/auth/**").permitAll()
                .requestMatchers("/api/public/**").permitAll()
                .requestMatchers("/api/admin/**").hasRole("ADMIN")
                .anyRequest().authenticated()
            )
            .oauth2ResourceServer(oauth2 -> oauth2
                .jwt(jwt -> jwt.decoder(jwtDecoder()))
            )
            .addFilterBefore(jwtAuthenticationFilter, UsernamePasswordAuthenticationFilter.class);
        
        return http.build();
    }
    
    @Bean
    public CorsConfigurationSource corsConfigurationSource() {
        CorsConfiguration configuration = new CorsConfiguration();
        configuration.setAllowedOriginPatterns(Arrays.asList("*"));
        configuration.setAllowedMethods(Arrays.asList("GET", "POST", "PUT", "DELETE", "OPTIONS"));
        configuration.setAllowedHeaders(Arrays.asList("*"));
        configuration.setAllowCredentials(true);
        
        UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
        source.registerCorsConfiguration("/**", configuration);
        return source;
    }
    
    @Bean
    public JwtDecoder jwtDecoder() {
        NimbusJwtDecoder jwtDecoder = new NimbusJwtDecoder(jwkSetUri());
        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 {
                // 自定义验证逻辑
                if (jwt.getExpiresAt().before(new Date())) {
                    throw new JwtValidationException("Token has expired");
                }
                // 可以添加更多验证逻辑
            }
        };
    }
    
    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }
    
    @Bean
    public AuthenticationManager authenticationManager(
            AuthenticationConfiguration authConfig) throws Exception {
        return authConfig.getAuthenticationManager();
    }
}

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是加密强度
    }
    
    @Bean
    public DelegatingPasswordEncoder passwordEncoder() {
        Map<String, PasswordEncoder> encoders = new HashMap<>();
        encoders.put("bcrypt", new BCryptPasswordEncoder(12));
        encoders.put("noop", NoOpPasswordEncoder.getInstance());
        
        DelegatingPasswordEncoder passwordEncoder = new DelegatingPasswordEncoder("bcrypt", encoders);
        passwordEncoder.setDefaultPasswordEncoderForMatches(new BCryptPasswordEncoder(12));
        
        return passwordEncoder;
    }
}

性能优化与监控

缓存机制实现

@Service
public class CachedPermissionService {
    
    @Autowired
    private PermissionService permissionService;
    
    @Cacheable(value = "permissions", key = "#username")
    public Set<String> getUserPermissions(String username) {
        // 从数据库获取权限信息
        return permissionService.getUserPermissions(username);
    }
    
    @CacheEvict(value = "permissions", key = "#username")
    public void clearUserPermissions(String username) {
        // 清除用户权限缓存
    }
    
    @CacheEvict(value = "permissions", allEntries = true)
    public void clearAllPermissions() {
        // 清除所有权限缓存
    }
}

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("Authentication successful for user: {}, IP: {}, Time: {}", 
                   username, ipAddress, new Date());
    }
    
    public void logAuthenticationFailure(String username, String ipAddress) {
        logger.warn("Authentication failed for user: {}, IP: {}, Time: {}", 
                   username, ipAddress, new Date());
    }
    
    public void logAuthorizationSuccess(String username, String resource, String action) {
        logger.info("Authorization successful for user: {}, Resource: {}, Action: {}, Time: {}", 
                   username, resource, action, new Date());
    }
    
    public void logAuthorizationFailure(String username, String resource, String action) {
        logger.warn("Authorization failed for user: {}, Resource: {}, Action: {}, Time: {}", 
                   username, resource, action, new Date());
    }
}
