用户认证机制详解

基于内存的认证实现

@Configuration
@EnableWebSecurity
public class SecurityConfig {
    
    @Bean
    public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
        http
            .authorizeHttpRequests(authz -> authz
                .requestMatchers("/public/**").permitAll()
                .anyRequest().authenticated()
            )
            .formLogin(form -> form
                .loginPage("/login")
                .permitAll()
            )
            .logout(logout -> logout.permitAll());
        
        return http.build();
    }
    
    @Bean
    public UserDetailsService userDetailsService() {
        UserDetails user = User.builder()
            .username("user")
            .password("{bcrypt}$2a$10$GRLdNijSQKU8r7AjKj6Zz.ZI2Y0X3Vf18iL49nB5CgOqDQHvZ9s3W")
            .roles("USER")
            .build();
            
        UserDetails admin = User.builder()
            .username("admin")
            .password("{bcrypt}$2a$10$GRLdNijSQKU8r7AjKj6Zz.ZI2Y0X3Vf18iL49nB5CgOqDQHvZ9s3W")
            .roles("USER", "ADMIN")
            .build();
            
        return new InMemoryUserDetailsManager(user, admin);
    }
}

基于数据库的认证实现

@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(user.getRoles().stream()
                .map(role -> new SimpleGrantedAuthority(role.getName()))
                .collect(Collectors.toList()))
            .accountExpired(false)
            .accountLocked(false)
            .credentialsExpired(false)
            .disabled(false)
            .build();
    }
}

@Configuration
@EnableWebSecurity
public class DatabaseSecurityConfig {
    
    @Autowired
    private CustomUserDetailsService userDetailsService;
    
    @Bean
    public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
        http
            .authorizeHttpRequests(authz -> authz
                .requestMatchers("/api/public/**").permitAll()
                .requestMatchers("/api/admin/**").hasRole("ADMIN")
                .anyRequest().authenticated()
            )
            .httpBasic(withDefaults())
            .sessionManagement(session -> session
                .sessionCreationPolicy(SessionCreationPolicy.IF_REQUIRED)
            );
            
        return http.build();
    }
    
    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }
}

权限控制机制

基于角色的访问控制(RBAC)

@RestController
@RequestMapping("/api/admin")
@PreAuthorize("hasRole('ADMIN')")
public class AdminController {
    
    @GetMapping("/users")
    @PreAuthorize("hasAuthority('USER_READ')")
    public List<User> getAllUsers() {
        return userService.findAll();
    }
    
    @PostMapping("/users")
    @PreAuthorize("hasAuthority('USER_CREATE')")
    public User createUser(@RequestBody User user) {
        return userService.save(user);
    }
    
    @DeleteMapping("/users/{id}")
    @PreAuthorize("hasAuthority('USER_DELETE')")
    public ResponseEntity<?> deleteUser(@PathVariable Long id) {
        userService.deleteById(id);
        return ResponseEntity.ok().build();
    }
}

基于方法级别的安全控制

@Service
public class UserService {
    
    @PreAuthorize("hasRole('ADMIN')")
    public List<User> findAll() {
        return userRepository.findAll();
    }
    
    @PostAuthorize("returnObject.username == authentication.name")
    public User findById(Long id) {
        return userRepository.findById(id).orElse(null);
    }
    
    @PreAuthorize("@userSecurityService.canUpdate(authentication, #user)")
    public User update(User user) {
        return userRepository.save(user);
    }
}

自定义权限表达式

@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
@PreAuthorize("@customPermissionEvaluator.hasPermission(authentication, #id, 'USER')")
public @interface CheckUserPermission {
    String value() default "";
}

@RestController
public class UserController {
    
    @GetMapping("/users/{id}")
    @CheckUserPermission
    public User getUser(@PathVariable Long id) {
        return userService.findById(id);
    }
}

JWT令牌管理实战

JWT配置与生成

@Component
public class JwtTokenProvider {
    
    private String secretKey = "mySecretKeyForJWTTokenGeneration";
    private int validityInMilliseconds = 3600000; // 1 hour
    
    @PostConstruct
    public void init() {
        secretKey = Base64.getEncoder().encodeToString(secretKey.getBytes());
    }
    
    public String createToken(Authentication authentication) {
        UserPrincipal userPrincipal = (UserPrincipal) authentication.getPrincipal();
        
        Date now = new Date();
        Date validity = new Date(now.getTime() + validityInMilliseconds);
        
        return Jwts.builder()
            .setSubject(userPrincipal.getUsername())
            .setIssuedAt(new Date())
            .setExpiration(validity)
            .signWith(SignatureAlgorithm.HS512, secretKey)
            .compact();
    }
    
    public String getUsernameFromToken(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");
        }
    }
}

JWT过滤器实现

public class JwtAuthenticationFilter extends OncePerRequestFilter {
    
    @Autowired
    private JwtTokenProvider jwtTokenProvider;
    
    @Autowired
    private CustomUserDetailsService userDetailsService;
    
    @Override
    protected void doFilterInternal(HttpServletRequest request, 
                                  HttpServletResponse response, 
                                  FilterChain filterChain) throws ServletException, IOException {
        
        String token = resolveToken(request);
        
        if (token != null && jwtTokenProvider.validateToken(token)) {
            String username = jwtTokenProvider.getUsernameFromToken(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;
    }
}

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

OAuth2协议集成实战

OAuth2客户端配置

@Configuration
@EnableWebSecurity
public class OAuth2ClientConfig {
    
    @Bean
    public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
        http
            .authorizeHttpRequests(authz -> authz
                .requestMatchers("/oauth2/**").permitAll()
                .anyRequest().authenticated()
            )
            .oauth2Login(oauth2 -> oauth2
                .loginPage("/login")
                .defaultSuccessUrl("/dashboard", true)
                .failureUrl("/login?error=true")
                .authorizationEndpoint(authz -> authz
                    .baseUri("/oauth2/authorize")
                    .authorizationRequestRepository(cookieAuthorizationRequestRepository())
                )
                .redirectionEndpoint(redir -> redir.baseUri("/oauth2/callback/*"))
                .userInfoEndpoint(userInfo -> userInfo
                    .userAuthoritiesMapper(userAuthoritiesMapper())
                )
            );
            
        return http.build();
    }
    
    @Bean
    public CookieSameSiteSupplier cookieSameSiteSupplier() {
        return CookieSameSiteSupplier.ofLax();
    }
    
    private OAuth2AuthorizedClientService authorizedClientService(
            ClientRegistrationRepository clientRegistrationRepository) {
        return new InMemoryOAuth2AuthorizedClientService(clientRegistrationRepository);
    }

        return converter;
    }
}

安全最佳实践

密码安全策略

@Configuration
public class PasswordSecurityConfig {
    
    @Bean
    public PasswordEncoder passwordEncoder() {
        BCryptPasswordEncoder encoder = new BCryptPasswordEncoder(12);
        
        // 自定义密码策略
        return new DelegatingPasswordEncoder("bcrypt", 
            Map.of("bcrypt", encoder));
    }
    
    @Bean
    public PasswordValidationService passwordValidationService() {
        return new PasswordValidationService() {
            @Override
            public boolean isValid(String password) {
                if (password == null || password.length() < 8) {
                    return false;
                }
                
                // 检查复杂度要求
                return password.matches("^(?=.*[0-9])(?=.*[a-z])(?=.*[A-Z])(?=.*[@#$%^&+=])(?=\\S+$).*$");
            }
        };
    }
}

安全头配置

@Configuration
public class SecurityHeadersConfig {
    
    @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.block(true))
                .cacheControl(cache -> cache.disable())
            );
            
        return http.build();
    }
}

会话管理策略

@Configuration
public class SessionManagementConfig {
    
    @Bean
    public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
        http
            .sessionManagement(session -> session
                .sessionCreationPolicy(SessionCreationPolicy.IF_REQUIRED)
                .maximumSessions(1)
                .maxSessionsPreventsLogin(false)
                .sessionRegistry(sessionRegistry())
            );
            
        return http.build();
    }
    
    @Bean
    public SessionRegistry sessionRegistry() {
        return new SessionRegistryImpl();
    }
}

性能优化与监控

缓存认证结果

@Service
public class CachedAuthenticationService {
    
    private final Cache<String, Authentication> cache = 
        Caffeine.newBuilder()
            .maximumSize(1000)
            .expireAfterWrite(30, TimeUnit.MINUTES)
            .build();
    
    public Authentication getAuthentication(String username) {
        return cache.getIfPresent(username);
    }
    
    public void putAuthentication(String username, Authentication authentication) {
        cache.put(username, authentication);
    }
    
    public void invalidateCache(String username) {
        cache.invalidate(username);
    }
}

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_LOGIN: User {} authenticated from IP {}", 
            username, ipAddress);
    }
    
    public void logAuthenticationFailure(String username, String ipAddress) {
        logger.warn("FAILED_LOGIN: Failed authentication attempt for user {} from IP {}", 
            username, ipAddress);
    }
    
    public void logAuthorizationFailure(String username, String resource, String action) {
        logger.warn("AUTHORIZATION_FAILURE: User {} attempted to {} on resource {}",
            username, action, resource);
    }
}
