3. 安全配置API改进

新的安全配置API更加简洁和直观，提供了更好的类型安全性和开发体验。通过引入新的DSL（领域特定语言）语法，开发者可以更轻松地配置复杂的安全策略。

OAuth2认证流程详解

1. OAuth2认证基础概念

OAuth2是一种开放的授权框架，允许第三方应用在用户授权的前提下访问用户的资源。在Spring Security 6.0中，OAuth2认证流程得到了全面的优化和简化。

2. OAuth2客户端配置

@Configuration
@EnableWebSecurity
public class OAuth2ClientConfig {
    
    @Bean
    public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
        http
            .oauth2Client(withDefaults())
            .oauth2Login(withDefaults())
            .authorizeHttpRequests(authz -> authz
                .anyRequest().authenticated()
            );
        return http.build();
    }
    
    @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);
    }
}

3. OAuth2认证流程解析

在Spring Security 6.0中，OAuth2认证流程包括以下关键步骤：

用户访问受保护资源：用户尝试访问需要认证的资源
重定向到认证服务器：系统将用户重定向到OAuth2认证服务器
用户授权：用户在认证服务器上进行登录和授权
回调处理：认证服务器将授权码回调到应用
令牌获取：应用使用授权码获取访问令牌
用户信息获取：应用使用访问令牌获取用户信息
认证完成：用户成功认证，获得访问权限

JWT令牌生成与验证实战

1. JWT令牌配置

@Configuration
public class JwtConfig {
    
    @Value("${jwt.secret}")
    private String secret;
    
    @Value("${jwt.expiration}")
    private Long expiration;
    
    @Bean
    public JwtDecoder jwtDecoder() {
        return NimbusJwtDecoder.withSecret(secret.getBytes(StandardCharsets.UTF_8))
            .build();
    }
    
    @Bean
    public JwtEncoder jwtEncoder() {
        JWKSet jwkSet = new JWKSet(new RSAKey.Builder((RSAPublicKey) getPublicKey())
            .privateKey((RSAPrivateKey) getPrivateKey())
            .build());
        return new NimbusJwtEncoder(jwkSet);
    }
    
    private PublicKey getPublicKey() {
        // 获取公钥的逻辑
        return null;
    }
    
    private PrivateKey getPrivateKey() {
        // 获取私钥的逻辑
        return null;
    }
}

2. JWT令牌生成服务

@Service
public class JwtTokenService {
    
    @Value("${jwt.secret}")
    private String secret;
    
    @Value("${jwt.expiration}")
    private Long expiration;
    
    public String generateToken(UserDetails userDetails) {
        Map<String, Object> claims = new HashMap<>();
        claims.put("authorities", userDetails.getAuthorities().stream()
            .map(GrantedAuthority::getAuthority)
            .collect(Collectors.toList()));
            
        return Jwts.builder()
            .setSubject(userDetails.getUsername())
            .setIssuedAt(new Date(System.currentTimeMillis()))
            .setExpiration(new Date(System.currentTimeMillis() + expiration * 1000))
            .addClaims(claims)
            .signWith(SignatureAlgorithm.HS512, secret)
            .compact();
    }
    
    public String getUsernameFromToken(String token) {
        return getClaimFromToken(token, Claims::getSubject);
    }
    
    public Date getExpirationDateFromToken(String token) {
        return getClaimFromToken(token, Claims::getExpiration);
    }
    
    public <T> T getClaimFromToken(String token, Function<Claims, T> claimsResolver) {
        final Claims claims = getAllClaimsFromToken(token);
        return claimsResolver.apply(claims);
    }
    
    private Claims getAllClaimsFromToken(String token) {
        return Jwts.parser().setSigningKey(secret).parseClaimsJws(token).getBody();
    }
    
    public Boolean isTokenExpired(String token) {
        final Date expiration = getExpirationDateFromToken(token);
        return expiration.before(new Date());
    }
}

3. JWT令牌验证过滤器

@Component
public class JwtAuthenticationFilter extends OncePerRequestFilter {
    
    @Autowired
    private JwtTokenService jwtTokenService;
    
    @Autowired
    private UserDetailsService userDetailsService;
    
    @Override
    protected void doFilterInternal(HttpServletRequest request, 
                                  HttpServletResponse response, 
                                  FilterChain filterChain) throws ServletException, IOException {
        
        final String requestTokenHeader = request.getHeader("Authorization");
        
        String username = null;
        String jwtToken = null;
        
        if (requestTokenHeader != null && requestTokenHeader.startsWith("Bearer ")) {
            jwtToken = requestTokenHeader.substring(7);
            try {
                username = jwtTokenService.getUsernameFromToken(jwtToken);
            } catch (IllegalArgumentException e) {
                logger.error("Unable to get JWT Token");
            } catch (Exception e) {
                logger.error("JWT Token has expired");
            }
        }
        
        if (username != null && SecurityContextHolder.getContext().getAuthentication() == null) {
            UserDetails userDetails = this.userDetailsService.loadUserByUsername(username);
            
            if (jwtTokenService.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

1. RBAC模型设计

基于角色的访问控制（RBAC）是一种广泛使用的权限管理模型。在Spring Security 6.0中，我们可以轻松实现完整的RBAC系统：

@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_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)
    private String name;
    
    @ManyToMany(mappedBy = "roles")
    private Set<User> users = new HashSet<>();
    
    // 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 = "role_permissions",
        joinColumns = @JoinColumn(name = "permission_id"),
        inverseJoinColumns = @JoinColumn(name = "role_id")
    )
    private Set<Role> roles = new HashSet<>();
    
    // getters and setters
}

2. 权限控制配置

@Configuration
@EnableWebSecurity
public class SecurityConfig {
    
    @Bean
    public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
        http
            .authorizeHttpRequests(authz -> authz
                .requestMatchers("/api/public/**").permitAll()
                .requestMatchers("/api/admin/**").hasRole("ADMIN")
                .requestMatchers("/api/user/**").hasAnyRole("USER", "ADMIN")
                .requestMatchers("/api/manager/**").hasAnyRole("MANAGER", "ADMIN")
                .anyRequest().authenticated()
            )
            .oauth2ResourceServer(oauth2 -> oauth2
                .jwt(jwt -> jwt.decoder(jwtDecoder()))
            )
            .sessionManagement(session -> session
                .sessionCreationPolicy(SessionCreationPolicy.STATELESS)
            );
        return http.build();
    }
    
    @Bean
    public JwtDecoder jwtDecoder() {
        return new NimbusJwtDecoder(jwkSet());
    }
    
    private JWKSet jwkSet() {
        // 返回JWK Set配置
        return new JWKSet();
    }
}

3. 自定义权限表达式

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

@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;
        }
        
        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)) {
                if (authority.contains(permission)) {
                    return true;
                }
            }
        }
        return false;
    }
}

完整安全认证实现示例

1. 用户认证服务

@Service
public class CustomUserDetailsService implements UserDetailsService {
    
    @Autowired
    private UserRepository userRepository;
    
    @Override
    public UserDetails loadUserByUsername(String username) throws UsernameNotFoundException {
        User user = userRepository.findByUsername(username)
            .orElseThrow(() -> new UsernameNotFoundException("User not found: " + username));
            
        return org.springframework.security.core.userdetails.User.builder()
            .username(user.getUsername())
            .password(user.getPassword())
            .authorities(getAuthorities(user.getRoles()))
            .accountExpired(false)
            .accountLocked(false)
            .credentialsExpired(false)
            .disabled(false)
            .build();
    }
    
    private Collection<? extends GrantedAuthority> getAuthorities(Set<Role> roles) {
        return roles.stream()
            .flatMap(role -> role.getPermissions().stream())
            .map(permission -> new SimpleGrantedAuthority(permission.getName()))
            .collect(Collectors.toList());
    }
}

2. 认证控制器

@RestController
@RequestMapping("/api/auth")
public class AuthController {
    
    @Autowired
    private AuthenticationManager authenticationManager;
    
    @Autowired
    private JwtTokenService jwtTokenService;
    
    @Autowired
    private UserService userService;
    
    @PostMapping("/login")
    public ResponseEntity<?> authenticateUser(@Valid @RequestBody LoginRequest loginRequest) {
        Authentication authentication = authenticationManager.authenticate(
            new UsernamePasswordAuthenticationToken(loginRequest.getUsername(), loginRequest.getPassword())
        );
        
        SecurityContextHolder.getContext().setAuthentication(authentication);
        String jwt = jwtTokenService.generateToken(authentication.getPrincipal());
        
        return ResponseEntity.ok(new JwtResponse(jwt));
    }
    
    @PostMapping("/register")
    public ResponseEntity<?> registerUser(@Valid @RequestBody SignUpRequest signUpRequest) {
        if (userService.existsByUsername(signUpRequest.getUsername())) {
            return ResponseEntity.badRequest()
                .body(new MessageResponse("Error: Username is already taken!"));
        }
        
        User user = userService.createUser(signUpRequest);
        
        return ResponseEntity.ok(new MessageResponse("User registered successfully!"));
    }
}

@Configuration
@EnableWebSecurity
@EnableMethodSecurity(prePostEnabled = true)
public class SecurityConfig {
    
    @Autowired
    private JwtAuthenticationFilter jwtAuthenticationFilter;
    
    @Autowired
    private CustomUserDetailsService userDetailsService;
    
    @Bean
    public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
        http.cors(withDefaults())
            .csrf(csrf -> csrf.disable())
            .authorizeHttpRequests(authz -> authz
                .requestMatchers("/api/auth/**").permitAll()

                .requestMatchers("/api/user/**").hasAnyRole("USER", "ADMIN")
                .requestMatchers("/api/manager/**").hasAnyRole("MANAGER", "ADMIN")
                .anyRequest().authenticated()
            )
            .sessionManagement(session -> session
                .sessionCreationPolicy(SessionCreationPolicy.STATELESS)
            )
            .oauth2ResourceServer(oauth2 -> oauth2
                .jwt(jwt -> jwt.decoder(jwtDecoder()))
            );
            
        http.addFilterBefore(jwtAuthenticationFilter, UsernamePasswordAuthenticationFilter.class);
        return http.build();
    }
    
    @Bean
    public AuthenticationManager authenticationManager(
        AuthenticationConfiguration authConfig) throws Exception {
        return authConfig.getAuthenticationManager();
    }
    
    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }
    
    @Bean
    public JwtDecoder jwtDecoder() {
        return new NimbusJwtDecoder(jwkSet());
    }
    
    private JWKSet jwkSet() {
        // 实现JWK Set配置
        return new JWKSet();
    }
}

最佳实践与安全建议

1. 密码安全策略

@Bean
public PasswordEncoder passwordEncoder() {
    // 使用BCrypt加密，迭代次数为12
    return new BCryptPasswordEncoder(12);
}

// 密码复杂度验证
@Component
public class PasswordValidator {
    
    public boolean isValid(String password) {
        if (password == null || password.length() < 8) {
            return false;
        }
        
        // 检查是否包含大写字母、小写字母、数字和特殊字符
        return password.matches("^(?=.*[a-z])(?=.*[A-Z])(?=.*\\d)(?=.*[@$!%*?&])[A-Za-z\\d@$!%*?&]");
    }
}

2. 令牌安全措施

@Configuration
public class TokenSecurityConfig {
    
    @Bean
    public JwtTokenService jwtTokenService() {
        return new JwtTokenService() {
            @Override
            public String generateToken(UserDetails userDetails) {
                // 添加额外的安全措施
                Map<String, Object> claims = new HashMap<>();
                claims.put("authorities", userDetails.getAuthorities().stream()
                    .map(GrantedAuthority::getAuthority)
                    .collect(Collectors.toList()));
                claims.put("iat", System.currentTimeMillis());
                claims.put("jti", UUID.randomUUID().toString());
                
                return Jwts.builder()
                    .setSubject(userDetails.getUsername())
                    .setIssuedAt(new Date(System.currentTimeMillis()))
                    .setExpiration(new Date(System.currentTimeMillis() + 86400000)) // 24小时
                    .addClaims(claims)
                    .signWith(SignatureAlgorithm.HS512, "your-secret-key")
                    .compact();
            }
        };
    }
}

3. 安全头配置

@Bean
public SecurityFilterChain filterChain(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.xssProtectionEnabled(true))
    );
    return http.build();
}
