JWT令牌机制实现

JWT基础概念

JSON Web Token (JWT) 是一个开放标准(RFC 7519)，用于在各方之间安全地传输信息。JWT由三部分组成：Header、Payload和Signature，这三部分通过点号(.)连接成一个字符串。

JWT在Spring Security中的集成

@Configuration
@EnableWebSecurity
public class JwtSecurityConfig {
    
    @Bean
    public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
        http
            .csrf().disable()
            .authorizeHttpRequests(authz -> authz
                .requestMatchers("/auth/**").permitAll()
                .anyRequest().authenticated()
            )
            .addFilterBefore(new JwtAuthenticationFilter(), UsernamePasswordAuthenticationFilter.class);
        
        return http.build();
    }
}

JWT生成与验证工具类

@Component
public class JwtTokenUtil {
    
    private String secret = "mySecretKey";
    private int jwtExpiration = 86400; // 24小时
    
    public String generateToken(UserDetails userDetails) {
        Map<String, Object> claims = new HashMap<>();
        return createToken(claims, userDetails.getUsername());
    }
    
    private String createToken(Map<String, Object> claims, String subject) {
        return Jwts.builder()
                .setClaims(claims)
                .setSubject(subject)
                .setIssuedAt(new Date(System.currentTimeMillis()))
                .setExpiration(new Date(System.currentTimeMillis() + jwtExpiration * 1000))
                .signWith(SignatureAlgorithm.HS512, secret)
                .compact();
    }
    
    public Boolean validateToken(String token, UserDetails userDetails) {
        final String username = getUsernameFromToken(token);
        return (username.equals(userDetails.getUsername()) && !isTokenExpired(token));
    }
    
    public String getUsernameFromToken(String token) {
        return getClaimFromToken(token, Claims::getSubject);
    }
    
    public Date getExpirationDateFromToken(String token) {
        return getClaimFromToken(token, Claims::getExpiration);
    }
    
    private <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();
    }
    
    private Boolean isTokenExpired(String token) {
        final Date expiration = getExpirationDateFromToken(token);
        return expiration.before(new Date());
    }
}

OAuth2授权框架集成

OAuth2核心概念

OAuth2是一个开放的授权框架，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：最安全的模式，适用于Web应用
隐式模式：适用于浏览器中的JavaScript应用
密码模式：适用于信任的应用
客户端凭证模式：适用于服务器到服务器的通信

OAuth2资源服务器配置

@Configuration
@EnableResourceServer
public class ResourceServerConfig {
    
    @Bean
    public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
        http
            .authorizeHttpRequests(authz -> authz
                .requestMatchers("/api/public/**").permitAll()
                .requestMatchers("/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解析器
        return jwtDecoder;
    }
}

OAuth2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://www.googleapis.com/oauth2/v4/token")
            .userInfoUri("https://www.googleapis.com/oauth2/v2/userinfo")
            .userNameAttributeName("sub")
            .scope("openid", "profile", "email")
            .clientName("Google")
            .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;
    }
}

RBAC权限模型实现

RBAC基础概念

基于角色的访问控制(RBAC)是一种广泛使用的权限管理模型。它通过将用户分配到角色，然后给角色分配权限来实现访问控制。RBAC的核心组件包括：

用户(User)：系统中的实体
角色(Role)：一组权限的集合
权限(Permission)：具体的操作权限
资源(Resource)：被保护的对象

RBAC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(255) NOT NULL,
    email VARCHAR(100),
    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
);

-- 权限表
CREATE TABLE permissions (
    id BIGINT PRIMARY KEY AUTO_INCREMENT,
    name VARCHAR(100) UNIQUE NOT NULL,
    description TEXT,
    resource VARCHAR(100),
    action VARCHAR(50)
);

-- 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)
);

-- 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)
);

RBAC权限管理服务

@Service
@Transactional
public class RbacPermissionService {
    
    @Autowired
    private UserRepository userRepository;
    
    @Autowired
    private RoleRepository roleRepository;
    
    @Autowired
    private PermissionRepository permissionRepository;
    
    @Autowired
    private UserRolesRepository userRolesRepository;
    
    @Autowired
    private RolePermissionsRepository rolePermissionsRepository;
    
    public void assignRoleToUser(Long userId, Long roleId) {
        // 检查用户和角色是否存在
        if (!userRepository.existsById(userId)) {
            throw new EntityNotFoundException("User not found");
        }
        if (!roleRepository.existsById(roleId)) {
            throw new EntityNotFoundException("Role not found");
        }
        
        // 检查是否已分配
        if (userRolesRepository.existsByUserIdAndRoleId(userId, roleId)) {
            return;
        }
        
        UserRoles userRoles = new UserRoles();
        userRoles.setUserId(userId);
        userRoles.setRoleId(roleId);
        userRolesRepository.save(userRoles);
    }
    
    public List<String> getUserPermissions(Long userId) {
        List<String> permissions = new ArrayList<>();
        
        // 获取用户所有角色
        List<Long> roleIds = userRolesRepository.findRoleIdsByUserId(userId);
        
        if (roleIds.isEmpty()) {
            return permissions;
        }
        
        // 获取所有角色的权限
        List<Permission> userPermissions = rolePermissionsRepository.findPermissionsByRoleIds(roleIds);
        
        for (Permission permission : userPermissions) {
            permissions.add(permission.getName());
        }
        
        return permissions;
    }
    
    public boolean hasPermission(Long userId, String permissionName) {
        List<String> userPermissions = getUserPermissions(userId);
        return userPermissions.contains(permissionName);
    }
}

自定义权限表达式

@Target({ElementType.METHOD, ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
@PreAuthorize("@rbacPermissionService.hasPermission(principal.id, #permission)")
public @interface RequirePermission {
    String permission();
}

// 使用示例
@RestController
@RequestMapping("/api/admin")
public class AdminController {
    
    @GetMapping("/users")
    @RequirePermission(permission = "user:read")
    public List<User> getUsers() {
        return userService.getAllUsers();
    }
    
    @PostMapping("/users")
    @RequirePermission(permission = "user:create")
    public User createUser(@RequestBody User user) {
        return userService.createUser(user);
    }
}

完整的安全认证流程实现

登录验证流程

@RestController
@RequestMapping("/auth")
public class AuthController {
    
    @Autowired
    private AuthenticationManager authenticationManager;
    
    @Autowired
    private JwtTokenUtil jwtTokenUtil;
    
    @Autowired
    private UserService userService;
    
    @PostMapping("/login")
    public ResponseEntity<?> login(@RequestBody LoginRequest loginRequest) {
        try {
            // 验证用户凭据
            Authentication authentication = authenticationManager.authenticate(
                new UsernamePasswordAuthenticationToken(
                    loginRequest.getUsername(),
                    loginRequest.getPassword()
                )
            );
            
            // 生成JWT令牌
            UserDetails userDetails = (UserDetails) authentication.getPrincipal();
            String token = jwtTokenUtil.generateToken(userDetails);
            
            // 获取用户权限信息
            List<String> permissions = rbacPermissionService.getUserPermissions(
                userService.findByUsername(loginRequest.getUsername()).getId()
            );
            
            LoginResponse response = new LoginResponse();
            response.setToken(token);
            response.setTokenType("Bearer");
            response.setPermissions(permissions);
            response.setUsername(userDetails.getUsername());
            
            return ResponseEntity.ok(response);
            
        } catch (AuthenticationException e) {
            return ResponseEntity.status(HttpStatus.UNAUTHORIZED)
                .body(new ErrorResponse("Invalid credentials"));
        }
    }
    
    @PostMapping("/refresh")
    public ResponseEntity<?> refreshToken(@RequestHeader("Authorization") String authHeader) {
        try {
            String token = authHeader.substring(7); // 去掉Bearer前缀
            String username = jwtTokenUtil.getUsernameFromToken(token);
            
            if (username != null && !jwtTokenUtil.isTokenExpired(token)) {
                UserDetails userDetails = userDetailsService.loadUserByUsername(username);
                String newToken = jwtTokenUtil.generateToken(userDetails);
                
                return ResponseEntity.ok(new TokenResponse(newToken));
            }
            
            return ResponseEntity.status(HttpStatus.UNAUTHORIZED)
                .body(new ErrorResponse("Invalid token"));
        } catch (Exception e) {
            return ResponseEntity.status(HttpStatus.UNAUTHORIZED)
                .body(new ErrorResponse("Token refresh failed"));
        }
    }
}

安全过滤器实现

@Component
public class JwtAuthenticationFilter extends OncePerRequestFilter {
    
    @Autowired
    private UserDetailsService userDetailsService;
    
    @Autowired
    private JwtTokenUtil jwtTokenUtil;
    
    @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 = jwtTokenUtil.getUsernameFromToken(jwtToken);
            } catch (IllegalArgumentException e) {
                logger.error("Unable to get JWT Token");
            } catch (Exception e) {
                logger.error("JWT Token has expired");
            }
        } else {
            logger.warn("JWT Token does not begin with Bearer String");
        }
        
        if (username != null && SecurityContextHolder.getContext().getAuthentication() == null) {
            UserDetails userDetails = this.userDetailsService.loadUserByUsername(username);
            
            if (jwtTokenUtil.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);
    }
}

    http.headers(headers -> headers
        .frameOptions(frameOptions -> frameOptions.deny())
        .contentTypeOptions(contentTypeOptions -> contentTypeOptions.disable())
        .httpStrictTransportSecurity(hsts -> hsts
            .maxAgeInSeconds(31536000)
            .includeSubdomains(true)
            .preload(true)
        )
    );
    
    return http.build();
}

最佳实践与安全建议

密码安全策略

@Bean
public PasswordEncoder passwordEncoder() {
    return new BCryptPasswordEncoder(12); // 使用12轮加密强度
}

// 配置密码策略
@Bean
public DelegatingPasswordEncoder passwordEncoder() {
    Map<String, PasswordEncoder> encoders = new HashMap<>();
    encoders.put("bcrypt", new BCryptPasswordEncoder(12));
    encoders.put("noop", NoOpPasswordEncoder.getInstance());
    
    return new DelegatingPasswordEncoder("bcrypt", encoders);
}

日志审计配置

@Component
public class SecurityAuditLogger {
    
    private static final Logger logger = LoggerFactory.getLogger(SecurityAuditLogger.class);
    
    public void logAuthenticationSuccess(String username, String ipAddress) {
        logger.info("Successful authentication for user: {}, IP: {}", username, ipAddress);
    }
    
    public void logAuthenticationFailure(String username, String ipAddress) {
        logger.warn("Failed authentication attempt for user: {}, IP: {}", username, ipAddress);
    }
    
    public void logAuthorizationFailure(String username, String resource, String action) {
        logger.warn("Authorization denied for user: {}, resource: {}, action: {}", 
                   username, resource, action);
    }
}

异常处理机制

@RestControllerAdvice
public class SecurityExceptionHandler {
    
    @ExceptionHandler(DisabledException.class)
    public ResponseEntity<ErrorResponse> handleDisabled(Exception ex) {
        return ResponseEntity.status(HttpStatus.FORBIDDEN)
            .body(new ErrorResponse("Account disabled"));
    }
    
    @ExceptionHandler(UsernameNotFoundException.class)
    public ResponseEntity<ErrorResponse> handleNotFound(Exception ex) {
        return ResponseEntity.status(HttpStatus.UNAUTHORIZED)
            .body(new ErrorResponse("User not found"));
    }
    
    @ExceptionHandler(AccessDeniedException.class)
    public ResponseEntity<ErrorResponse> handleAccessDenied(Exception ex) {
        return ResponseEntity.status(HttpStatus.FORBIDDEN)
            .body(new ErrorResponse("Access denied"));
    }
}
