Spring Security 6.0新特性概览

核心改进

Spring Security 6.0在安全性方面进行了重大升级，主要体现在以下几个方面：

默认启用HTTPS：所有配置都默认使用HTTPS协议
密码编码器升级：默认使用BCryptPasswordEncoder
WebSecurityConfigurerAdapter废弃：采用新的基于Java配置方式
增强的OAuth2支持：提供更完整的OAuth2实现

配置方式变化

@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();
    }
}

JWT令牌认证机制详解

JWT基础概念

JSON Web Token (JWT) 是一个开放标准(RFC 7519)，定义了一种紧凑且自包含的方式，用于在各方之间安全地传输信息作为JSON对象。

JWT结构组成

JWT由三部分组成，用点(.)分隔：

{
  "header": {
    "alg": "HS256",
    "typ": "JWT"
  },
  "payload": {
    "sub": "1234567890",
    "name": "John Doe",
    "iat": 1516239022,
    "exp": 1516242622
  },
  "signature": "HMACSHA256(...)="
}

Spring Security中的JWT实现

@Component
public class JwtTokenProvider {
    
    private final String secretKey = "mySecretKey";
    private final int validityInMilliseconds = 3600000; // 1 hour
    
    @PostConstruct
    protected void init() {
        secretKey = Base64.getEncoder().encodeToString(secretKey.getBytes());
    }
    
    public String createToken(String username, List<String> roles) {
        Claims claims = Jwts.claims().setSubject(username);
        claims.put("roles", roles);
        
        Date now = new Date();
        Date validity = new Date(now.getTime() + validityInMilliseconds);
        
        return Jwts.builder()
                .setClaims(claims)
                .setIssuedAt(now)
                .setExpiration(validity)
                .signWith(SignatureAlgorithm.HS256, secretKey)
                .compact();
    }
    
    public String getUsername(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

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

完整的JWT安全配置

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

OAuth2授权框架深度解析

OAuth2核心概念

OAuth2是一种开放的授权标准，允许第三方应用获取对HTTP服务的有限访问权限。它定义了四种授权模式：

授权码模式：最安全，适用于服务器端应用
隐式模式：适用于浏览器端应用
密码模式：适用于信任的应用
客户端凭证模式：适用于服务器间通信

OAuth2 Resource Server配置

@Configuration
@EnableResourceServer
public class OAuth2ResourceServerConfig {
    
    @Bean
    public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
        http
            .authorizeRequests(authz -> authz
                .antMatchers("/api/public/**").permitAll()
                .antMatchers("/api/admin/**").hasRole("ADMIN")
                .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 OAuth2TokenValidator<Jwt>() {
            @Override
            public OAuth2Error validate(Jwt token) {
                if (token.getExpiresAt().isBefore(Instant.now())) {
                    return new OAuth2Error("invalid_token", "Token has expired", null);
                }
                return null;
            }
        });
        return jwtDecoder;
    }
}

自定义OAuth2认证处理

@Component
public class CustomOAuth2UserService implements OAuth2UserService<OAuth2UserRequest, OAuth2User> {
    
    @Override
    public OAuth2User loadUser(OAuth2UserRequest userRequest) throws OAuth2AuthenticationException {
        OAuth2User oauth2User = super.loadUser(userRequest);
        
        String username = oauth2User.getAttribute("email");
        String fullName = oauth2User.getAttribute("name");
        
        // 根据用户信息创建Spring Security的UserDetails
        Collection<SimpleGrantedAuthority> authorities = 
            Arrays.asList(new SimpleGrantedAuthority("ROLE_USER"));
            
        return new User(username, "", authorities);
    }
}

OAuth2客户端配置

@Configuration
@EnableOAuth2Client
public class OAuth2ClientConfig {
    
    @Bean
    public ClientRegistrationRepository clientRegistrationRepository() {
        ClientRegistration googleClientRegistration = ClientRegistration.withRegistrationId("google")
            .clientId("your-client-id")
            .clientSecret("your-client-secret")
            .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")
            .authorizationGrantType(AuthorizationGrantType.AUTHORIZATION_CODE)
            .redirectUri("{baseUrl}/login/oauth2/code/{registrationId}")
            .build();
            
        return new InMemoryClientRegistrationRepository(googleClientRegistration);
    }
}

RBAC权限控制实现

RBAC核心概念

基于角色的访问控制(Role-Based Access Control, RBAC)是一种广泛使用的权限管理模型。它通过将权限分配给角色，然后将角色分配给用户来实现访问控制。

数据库设计

-- 用户表
CREATE TABLE users (
    id BIGINT PRIMARY KEY AUTO_INCREMENT,
    username VARCHAR(50) UNIQUE NOT NULL,
    password VARCHAR(100) NOT NULL,
    email VARCHAR(100),
    enabled BOOLEAN DEFAULT TRUE,
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

-- 角色表
CREATE TABLE roles (
    id BIGINT PRIMARY KEY AUTO_INCREMENT,
    name VARCHAR(50) UNIQUE NOT NULL,
    description TEXT
);

-- 用户角色关联表
CREATE TABLE user_roles (
    user_id BIGINT,
    role_id BIGINT,
    PRIMARY KEY (user_id, role_id),
    FOREIGN KEY (user_id) REFERENCES users(id),
    FOREIGN KEY (role_id) REFERENCES roles(id)
);

-- 权限表
CREATE TABLE permissions (
    id BIGINT PRIMARY KEY AUTO_INCREMENT,
    name VARCHAR(100) UNIQUE NOT NULL,
    description TEXT
);

-- 角色权限关联表
CREATE TABLE role_permissions (
    role_id BIGINT,
    permission_id BIGINT,
    PRIMARY KEY (role_id, permission_id),
    FOREIGN KEY (role_id) REFERENCES roles(id),
    FOREIGN KEY (permission_id) REFERENCES permissions(id)
);

实体类定义

@Entity
@Table(name = "users")
public class User {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    
    @Column(unique = true, nullable = false)
    private String username;
    
    @Column(nullable = false)
    private String password;
    
    @Column(unique = true)
    private String email;
    
    @Column(name = "enabled")
    private Boolean enabled = true;
    
    @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, nullable = false)
    private String name;
    
    @Column
    private String description;
    
    @ManyToMany(fetch = FetchType.EAGER)
    @JoinTable(
        name = "role_permissions",
        joinColumns = @JoinColumn(name = "role_id"),
        inverseJoinColumns = @JoinColumn(name = "permission_id")
    )
    private Set<Permission> permissions = new HashSet<>();
    
    // getters and setters
}

@Entity
@Table(name = "permissions")
public class Permission {
    @Id
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private Long id;
    
    @Column(unique = true, nullable = false)
    private String name;
    
    @Column
    private String description;
    
    // getters and setters
}

权限服务实现

@Service
@Transactional
public class PermissionService {
    
    @Autowired
    private UserRepository userRepository;
    
    @Autowired
    private RoleRepository roleRepository;
    
    @Autowired
    private PermissionRepository permissionRepository;
    
    public Set<String> getUserPermissions(String username) {
        User user = userRepository.findByUsername(username)
            .orElseThrow(() -> new UsernameNotFoundException("User not found"));
            
        Set<String> permissions = new HashSet<>();
        
        for (Role role : user.getRoles()) {
            for (Permission permission : role.getPermissions()) {
                permissions.add(permission.getName());
            }
        }
        
        return permissions;
    }
    
    public boolean hasPermission(String username, String permission) {
        Set<String> userPermissions = getUserPermissions(username);
        return userPermissions.contains(permission);
    }
    
    @PreAuthorize("hasRole('ADMIN')")
    public void assignPermissionToRole(Long roleId, Long permissionId) {
        Role role = roleRepository.findById(roleId)
            .orElseThrow(() -> new EntityNotFoundException("Role not found"));
            
        Permission permission = permissionRepository.findById(permissionId)
            .orElseThrow(() -> new EntityNotFoundException("Permission not found"));
            
        role.getPermissions().add(permission);
        roleRepository.save(role);
    }
}

RBAC安全配置

@Configuration
@EnableWebSecurity
public class RbacSecurityConfig {
    
    @Bean
    public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
        http
            .authorizeHttpRequests(authz -> authz
                .requestMatchers("/admin/**").hasRole("ADMIN")
                .requestMatchers("/user/**").hasAnyRole("USER", "ADMIN")
                .requestMatchers("/public/**").permitAll()
                .requestMatchers("/api/secure/**").authenticated()
                .anyRequest().denyAll()
            )
            .formLogin(form -> form
                .loginPage("/login")
                .defaultSuccessUrl("/dashboard")
                .permitAll()
            )
            .logout(logout -> logout
                .logoutUrl("/logout")
                .logoutSuccessUrl("/login?logout")
                .permitAll()
            );
            
        return http.build();
    }
    
    @Bean
    public AuthenticationManager authenticationManager(
            AuthenticationConfiguration authConfig) throws Exception {
        return authConfig.getAuthenticationManager();
    }
}

自定义权限表达式

@Target(ElementType.METHOD)
@Retention(RetentionPolicy.RUNTIME)
@PreAuthorize("@permissionService.hasPermission(principal.username, #permission)")
public @interface HasPermission {
    String permission();
}

// 使用示例
@RestController
@RequestMapping("/api")
public class UserController {
    
    @GetMapping("/users/{id}")
    @HasPermission(permission = "user:read")
    public User getUser(@PathVariable Long id) {
        return userService.findById(id);
    }
    
    @PostMapping("/users")
    @HasPermission(permission = "user:create")
    public User createUser(@RequestBody User user) {
        return userService.save(user);
    }
}

最佳实践与安全建议

安全配置最佳实践

使用HTTPS：确保所有通信都通过HTTPS进行
适当设置超时时间：避免令牌过期时间过长
定期轮换密钥：定期更新JWT签名密钥
实施速率限制：防止暴力破解攻击

性能优化建议

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

异常处理机制

@ControllerAdvice
public class SecurityExceptionHandler {
    
    @ExceptionHandler(AuthenticationException.class)
    public ResponseEntity<ErrorResponse> handleAuthenticationError(
            AuthenticationException ex) {
        ErrorResponse error = new ErrorResponse("Authentication failed");
        return ResponseEntity.status(HttpStatus.UNAUTHORIZED).body(error);
    }
    
    @ExceptionHandler(AccessDeniedException.class)
    public ResponseEntity<ErrorResponse> handleAccessDenied(
            AccessDeniedException ex) {
        ErrorResponse error = new ErrorResponse("Access denied");
        return ResponseEntity.status(HttpStatus.FORBIDDEN).body(error);
    }
}
