OAuth2认证机制实现

OAuth2认证流程详解

OAuth2是一种开放的授权标准，允许第三方应用在用户授权的情况下访问用户资源。在Spring Security 6.0中，我们可以通过以下步骤实现完整的OAuth2认证流程：

@Configuration
@EnableWebSecurity
public class OAuth2SecurityConfig {

    @Bean
    public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
        http
            .oauth2Login(oauth2 -> oauth2
                .loginPage("/login")
                .defaultSuccessUrl("/dashboard")
                .failureUrl("/login?error=true")
                .permitAll()
            )
            .oauth2Client(withDefaults())
            .authorizeHttpRequests(authz -> authz
                .requestMatchers("/login", "/oauth2/**").permitAll()
                .anyRequest().authenticated()
            );
        return http.build();
    }
}

Google OAuth2集成示例

@Configuration
public class OAuth2ClientConfig {
    
    @Bean
    @Primary
    public ClientRegistrationRepository clientRegistrationRepository() {
        ClientRegistration googleClientRegistration = ClientRegistration.withRegistrationId("google")
            .clientId("your-google-client-id")
            .clientSecret("your-google-client-secret")
            .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}")
            .scope("openid", "profile", "email")
            .build();
            
        return new InMemoryClientRegistrationRepository(googleClientRegistration);
    }
}

自定义OAuth2用户服务

@Service
public class CustomOAuth2UserService implements OAuth2UserService<OAuth2AuthenticationToken, OAuth2User> {
    
    @Autowired
    private UserRepository userRepository;
    
    @Override
    public OAuth2User loadUser(OAuth2AuthenticationToken authentication) throws OAuth2AuthenticationException {
        OAuth2User oAuth2User = new DefaultOAuth2User(
            Collections.singleton(new SimpleGrantedAuthority("ROLE_USER")),
            authentication.getPrincipal().getAttributes(),
            "sub"
        );
        
        String email = oAuth2User.getAttribute("email");
        String name = oAuth2User.getAttribute("name");
        
        User user = userRepository.findByEmail(email)
            .orElseGet(() -> {
                User newUser = new User();
                newUser.setEmail(email);
                newUser.setName(name);
                newUser.setProvider("google");
                newUser.setCreatedAt(LocalDateTime.now());
                return userRepository.save(newUser);
            });
            
        return new CustomUserDetails(user, oAuth2User.getAttributes());
    }
}

JWT令牌管理与安全实现

JWT基础概念与优势

JWT（JSON Web Token）是一种开放标准（RFC 7519），用于在各方之间安全地传输信息。JWT令牌的优势包括：

无状态：服务器不需要存储会话信息
跨域支持：可以在不同域之间传递
信息丰富：可以在令牌中包含用户信息
安全性高：通过签名保证数据完整性

JWT配置与生成

@Component
public class JwtTokenProvider {
    
    @Value("${jwt.secret}")
    private String secretKey;
    
    @Value("${jwt.expiration}")
    private Long validityInMilliseconds;
    
    @PostConstruct
    protected void init() {
        secretKey = Base64.getEncoder().encodeToString(secretKey.getBytes());
    }
    
    public String createToken(UserDetails userDetails, List<String> roles) {
        Claims claims = Jwts.claims().setSubject(userDetails.getUsername());
        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.HS512, secretKey)
            .compact();
    }
    
    public String getUsername(String token) {
        return Jwts.parser()
            .setSigningKey(secretKey)
            .parseClaimsJws(token)
            .getBody()
            .getSubject();
    }
    
    public boolean validateToken(String token) {
        try {
            Jws<Claims> claims = Jwts.parser()
                .setSigningKey(secretKey)
                .parseClaimsJws(token);
            return !claims.getBody().getExpiration().before(new Date());
        } catch (JwtException | IllegalArgumentException e) {
            return false;
        }
    }
}

JWT安全增强措施

@Configuration
public class JwtSecurityConfig {
    
    @Bean
    public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
        http
            .sessionManagement(session -> session
                .sessionCreationPolicy(SessionCreationPolicy.STATELESS)
            )
            .authorizeHttpRequests(authz -> authz
                .requestMatchers("/api/auth/**").permitAll()
                .requestMatchers("/api/public/**").permitAll()
                .anyRequest().authenticated()
            )
            .addFilterBefore(new JwtAuthenticationFilter(), UsernamePasswordAuthenticationFilter.class)
            .exceptionHandling(exceptions -> exceptions
                .authenticationEntryPoint(new JwtAuthenticationEntryPoint())
                .accessDeniedHandler(new JwtAccessDeniedHandler())
            );
        return http.build();
    }
}

JWT认证过滤器实现

@Component
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.getUsername(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;
    }
}

基于角色的访问控制（RBAC）实现

RBAC核心概念

基于角色的访问控制（RBAC）是一种访问控制模型，通过将权限分配给角色，再将角色分配给用户来实现访问控制。RBAC模型包含三个核心组件：

用户（User）：系统中的个体
角色（Role）：权限的集合
权限（Permission）：具体的操作权限

角色权限数据模型

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

RBAC权限控制实现

@Service
public class RBACService {
    
    @Autowired
    private UserRepository userRepository;
    
    @Autowired
    private RoleRepository roleRepository;
    
    @Autowired
    private PermissionRepository permissionRepository;
    
    public boolean hasPermission(String username, String permissionName) {
        User user = userRepository.findByEmail(username)
            .orElseThrow(() -> new UsernameNotFoundException("User not found"));
            
        return user.getRoles().stream()
            .flatMap(role -> role.getPermissions().stream())
            .anyMatch(permission -> permission.getName().equals(permissionName));
    }
    
    public boolean hasRole(String username, String roleName) {
        User user = userRepository.findByEmail(username)
            .orElseThrow(() -> new UsernameNotFoundException("User not found"));
            
        return user.getRoles().stream()
            .anyMatch(role -> role.getName().equals(roleName));
    }
    
    public Set<String> getUserRoles(String username) {
        User user = userRepository.findByEmail(username)
            .orElseThrow(() -> new UsernameNotFoundException("User not found"));
            
        return user.getRoles().stream()
            .map(Role::getName)
            .collect(Collectors.toSet());
    }
}

基于注解的权限控制

@Target({ElementType.METHOD, ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
@PreAuthorize("hasRole('ADMIN')")
public @interface AdminOnly {
}

@Target({ElementType.METHOD, ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
@PreAuthorize("hasAnyRole('ADMIN', 'USER')")
public @interface UserOrAdmin {
}

@RestController
@RequestMapping("/api/admin")
public class AdminController {
    
    @GetMapping("/users")
    @AdminOnly
    public List<User> getAllUsers() {
        // 只有管理员可以访问
        return userService.getAllUsers();
    }
    
    @GetMapping("/reports")
    @UserOrAdmin
    public List<Report> getReports() {
        // 管理员和普通用户都可以访问
        return reportService.getReports();
    }
}

动态权限控制实现

@Component
public class DynamicPermissionEvaluator implements PermissionEvaluator {
    
    @Autowired
    private RBACService rbacService;
    
    @Override
    public boolean hasPermission(Authentication authentication, Object targetDomainObject, Object permission) {
        if (authentication == null || !(targetDomainObject instanceof String)) {
            return false;
        }
        
        String targetType = targetDomainObject.toString().toLowerCase();
        String user = authentication.getName();
        
        // 根据权限名称进行动态检查
        return rbacService.hasPermission(user, (String) permission);
    }
    
    @Override
    public boolean hasPermission(Authentication authentication, Serializable targetId, String targetType, Object permission) {
        if (authentication == null || !(targetType instanceof String)) {
            return false;
        }
        
        String user = authentication.getName();
        return rbacService.hasPermission(user, (String) permission);
    }
}
