安全配置的现代化

Spring Boot 3.0对安全配置进行了简化和优化：

# application.yml
spring:
  security:
    oauth2:
      client:
        registration:
          google:
            client-id: ${GOOGLE_CLIENT_ID}
            client-secret: ${GOOGLE_CLIENT_SECRET}
            scope: openid,profile,email
        provider:
          google:
            issuer-uri: https://accounts.google.com

配置类重构

@Configuration
@EnableWebSecurity
public class SecurityConfig {

    @Bean
    public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
        http
            .authorizeHttpRequests(authz -> authz
                .requestMatchers("/public/**").permitAll()
                .requestMatchers("/admin/**").hasRole("ADMIN")
                .anyRequest().authenticated()
            )
            .oauth2Login(oauth2 -> oauth2
                .defaultSuccessUrl("/dashboard")
                .failureUrl("/login?error=true")
            );
        return http.build();
    }
}

Spring Security 6.0 核心安全机制

认证机制升级

Spring Security 6.0在认证机制方面进行了重大改进，主要体现在：

基于角色的认证优化

@Configuration
@EnableWebSecurity
public class AuthenticationConfig {

    @Bean
    public AuthenticationManager authenticationManager(
            AuthenticationConfiguration authConfig) throws Exception {
        return authConfig.getAuthenticationManager();
    }

    @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")
                .anyRequest().authenticated()
            )
            .formLogin(form -> form
                .loginPage("/login")
                .defaultSuccessUrl("/dashboard")
                .permitAll()
            )
            .logout(logout -> logout
                .permitAll()
                .logoutSuccessUrl("/login?logout")
            );
        return http.build();
    }
}

自定义认证提供者

@Component
public class CustomAuthenticationProvider implements AuthenticationProvider {

    @Autowired
    private UserService userService;

    @Override
    public Authentication authenticate(Authentication authentication) 
            throws AuthenticationException {
        
        String username = authentication.getName();
        String password = authentication.getCredentials().toString();

        UserDetails userDetails = userService.loadUserByUsername(username);
        
        if (userDetails != null && passwordEncoder.matches(password, userDetails.getPassword())) {
            return new UsernamePasswordAuthenticationToken(
                username, password, userDetails.getAuthorities());
        }
        
        throw new BadCredentialsException("Authentication failed");
    }

    @Override
    public boolean supports(Class<?> authentication) {
        return UsernamePasswordAuthenticationToken.class.isAssignableFrom(authentication);
    }
}

授权体系重构

Spring Security 6.0的授权体系更加灵活和强大：

基于表达式的授权

@Configuration
@EnableMethodSecurity(prePostEnabled = true)
public class MethodSecurityConfig {

    @Bean
    public MethodSecurityExpressionHandler expressionHandler() {
        DefaultMethodSecurityExpressionHandler handler = 
            new DefaultMethodSecurityExpressionHandler();
        handler.setPermissionEvaluator(new CustomPermissionEvaluator());
        return handler;
    }
}

@Service
public class UserService {
    
    @PreAuthorize("hasRole('ADMIN')")
    public List<User> getAllUsers() {
        // 实现逻辑
        return userRepository.findAll();
    }
    
    @PreAuthorize("@customPermissionEvaluator.hasPermission(authentication, #userId)")
    public User getUserById(Long userId) {
        // 实现逻辑
        return userRepository.findById(userId);
    }
}

动态授权决策

@Component
public class DynamicAuthorizationManager implements AuthorizationManager<RequestAuthorizationContext> {

    @Override
    public AuthorizationDecision check(
            Supplier<Authentication> authentication, 
            RequestAuthorizationContext context) {
        
        HttpServletRequest request = context.getRequest();
        String role = getRoleFromRequest(request);
        
        return authentication.get()
            .getAuthorities()
            .stream()
            .anyMatch(grantedAuthority -> grantedAuthority.getAuthority().equals(role))
            ? new AuthorizationDecision(true)
            : new AuthorizationDecision(false);
    }
    
    private String getRoleFromRequest(HttpServletRequest request) {
        // 从请求中提取角色信息
        return request.getHeader("X-User-Roles");
    }
}

OAuth2 集成与实现

客户端配置优化

Spring Security 6.0对OAuth2客户端支持进行了重大改进：

# application.yml
spring:
  security:
    oauth2:
      client:
        registration:
          github:
            client-id: ${GITHUB_CLIENT_ID}
            client-secret: ${GITHUB_CLIENT_SECRET}
            scope: read:user,user:email
            redirect-uri: "{baseUrl}/login/oauth2/code/{registrationId}"
          google:
            client-id: ${GOOGLE_CLIENT_ID}
            client-secret: ${GOOGLE_CLIENT_SECRET}
            scope: openid,profile,email
        provider:
          github:
            issuer-uri: https://github.com/login/oauth/authorize
          google:
            issuer-uri: https://accounts.google.com

自定义OAuth2登录处理器

@Component
public class CustomOAuth2SuccessHandler implements AuthenticationSuccessHandler {

    @Autowired
    private JwtTokenProvider jwtTokenProvider;

    @Override
    public void onAuthenticationSuccess(
            HttpServletRequest request, 
            HttpServletResponse response,
            Authentication authentication) throws IOException, ServletException {
        
        OAuth2User oauth2User = (OAuth2User) authentication.getPrincipal();
        
        // 构建JWT令牌
        String token = jwtTokenProvider.generateToken(authentication);
        
        // 重定向到前端应用
        String redirectUrl = "/dashboard?token=" + token;
        response.sendRedirect(redirectUrl);
    }
}

@Configuration
public class OAuth2Config {
    
    @Bean
    public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
        http
            .oauth2Login(oauth2 -> oauth2
                .successHandler(customOAuth2SuccessHandler)
                .failureUrl("/login?error=true")
                .defaultSuccessUrl("/dashboard")
            );
        return http.build();
    }
}

OAuth2资源服务器配置

@Configuration
@EnableMethodSecurity
public class ResourceServerConfig {
    
    @Bean
    public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
        http
            .authorizeHttpRequests(authz -> authz
                .requestMatchers("/api/public/**").permitAll()
                .requestMatchers("/api/secure/**").authenticated()
                .anyRequest().authenticated()
            )
            .oauth2ResourceServer(oauth2 -> oauth2
                .jwt(jwt -> jwt
                    .decoder(jwtDecoder())
                )
            );
        return http.build();
    }
    
    @Bean
    public JwtDecoder jwtDecoder() {
        NimbusJwtDecoder jwtDecoder = new NimbusJwtDecoder(jwkSetUri);
        // 配置JWT验证器
        jwtDecoder.setJwtValidator(new CustomJwtValidator());
        return jwtDecoder;
    }
}

JWT 令牌管理与安全实现

JWT 令牌生成器

@Component
public class JwtTokenProvider {
    
    private final String secretKey = "mySecretKeyForJWTGeneration";
    private final int validityInMilliseconds = 3600000; // 1小时
    
    @Bean
    public JwtEncoder jwtEncoder() {
        return new NimbusJwtEncoder(new JWKSet<>(new RSAKey.Builder(generateKeyPair())
            .keyUse(KeyUse.SIGNATURE)
            .algorithm(JWSAlgorithm.RS256)
            .build()));
    }
    
    public String generateToken(Authentication authentication) {
        UserDetails user = (UserDetails) authentication.getPrincipal();
        
        Instant now = Instant.now();
        Instant expiry = now.plusSeconds(validityInMilliseconds / 1000);
        
        JwtClaimsSet claims = JwtClaimsSet.builder()
            .issuer("my-app")
            .issuedAt(now)
            .expiresAt(expiry)
            .subject(user.getUsername())
            .claim("roles", user.getAuthorities().stream()
                .map(GrantedAuthority::getAuthority)
                .collect(Collectors.toList()))
            .build();
            
        return jwtEncoder.encode(JwtEncoderParameters.from(claims)).getTokenValue();
    }
    
    public String getUsernameFromToken(String token) {
        try {
            Jwt jwt = jwtDecoder.decode(token);
            return jwt.getSubject();
        } catch (JwtException e) {
            throw new InvalidJwtTokenException("Invalid JWT token", e);
        }
    }
}

            HttpServletRequest request, 
            HttpServletResponse response, 
            FilterChain filterChain) throws ServletException, IOException {
        
        String token = resolveToken(request);
        
        if (token != null && jwtTokenProvider.validate(token)) {
            Authentication auth = getAuthentication(token);
            SecurityContextHolder.getContext().setAuthentication(auth);
        }
        
        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;
    }
}

    }
}

@Component
public class RateLimitingFilter extends OncePerRequestFilter {
    
    private final RateLimiter rateLimiter = RateLimiter.create(10.0); // 10次/秒
    
    @Override
    protected void doFilterInternal(
            HttpServletRequest request, 
            HttpServletResponse response, 
            FilterChain filterChain) throws ServletException, IOException {
        
        if (!rateLimiter.tryAcquire()) {
            response.setStatus(HttpStatus.TOO_MANY_REQUESTS.value());
            response.getWriter().write("Rate limit exceeded");
            return;
        }
        
        filterChain.doFilter(request, response);
    }
}
