OAuth2授权服务器配置
授权服务器基础配置
Spring Security 6.0引入了专门的OAuth2授权服务器支持，通过spring-boot-starter-oauth2-authorization-server依赖实现。
@Configuration
@EnableWebSecurity
public class AuthorizationServerConfig {
@Bean
public ClientRegistrationRepository clientRegistrationRepository() {
RegisteredClient registeredClient = RegisteredClient.withId(UUID.randomUUID().toString())
.clientId("client-id")
.clientSecret("{noop}client-secret")
.authorizationGrantType(AuthorizationGrantType.AUTHORIZATION_CODE)
.authorizationGrantType(AuthorizationGrantType.REFRESH_TOKEN)
.redirectUri("http://localhost:8080/login/oauth2/code/client")
.scope("read")
.scope("write")
.clientAuthenticationMethod(ClientAuthenticationMethod.CLIENT_SECRET_BASIC)
.build();
return new InMemoryClientRegistrationRepository(registeredClient);
}
@Bean
public JWKSetRepository jwkSetRepository() {
RSAKey rsaKey = generateRsa();
JWKSet jwkSet = new JWKSet(rsaKey);
return new ImmutableJWKSet<>(jwkSet);
}
private RSAKey generateRsa() {
KeyPair keyPair = KeyGeneratorUtils.generateRsaKey();
RSAPublicKey publicKey = (RSAPublicKey) keyPair.getPublic();
RSAPrivateKey privateKey = (RSAPrivateKey) keyPair.getPrivate();
return new RSAKey.Builder(publicKey)
.privateKey(privateKey)
.keyID(UUID.randomUUID().toString())
.build();
}
}
授权服务器安全配置
@Configuration
public class AuthorizationServerSecurityConfig {
@Bean
public SecurityFilterChain authorizationServerSecurityFilterChain(HttpSecurity http)
throws Exception {
OAuth2AuthorizationServerConfiguration.applyDefaultSecurity(http);
http.getConfigurer(OAuth2AuthorizationServerConfigurer.class)
.oidc(Customizer.withDefaults());
return http.build();
}
@Bean
public RegisteredClientRepository registeredClientRepository() {
// 注册客户端信息
RegisteredClient registeredClient = RegisteredClient.withId(UUID.randomUUID().toString())
.clientId("client-id")
.clientSecret("{noop}client-secret")
.authorizationGrantType(AuthorizationGrantType.AUTHORIZATION_CODE)
.redirectUri("http://localhost:8080/login/oauth2/code/client")
.scope(OidcScopes.OPENID)
.scope(OidcScopes.PROFILE)
.clientAuthenticationMethod(ClientAuthenticationMethod.CLIENT_SECRET_BASIC)
.build();
return new InMemoryRegisteredClientRepository(registeredClient);
}
}
JWT令牌生成与验证
JWT配置类实现
@Component
public class JwtConfig {
@Value("${jwt.secret}")
private String secret;
@Value("${jwt.expiration}")
private Long expiration;
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() + expiration * 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);
}
public <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());
}
}
JWT认证过滤器实现
@Component
public class JwtAuthenticationFilter extends OncePerRequestFilter {
@Autowired
private JwtConfig jwtConfig;
@Autowired
private UserDetailsService userDetailsService;
@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 = jwtConfig.getUsernameFromToken(jwtToken);
} catch (IllegalArgumentException e) {
logger.error("无法获取JWT令牌", e);
} catch (Exception e) {
logger.error("JWT令牌无效", e);
}
} else {
logger.warn("JWT令牌不以Bearer开头");
}
if (username != null && SecurityContextHolder.getContext().getAuthentication() == null) {
UserDetails userDetails = this.userDetailsService.loadUserByUsername(username);
if (jwtConfig.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);
}
}
RBAC权限控制实现
权限实体定义
@Entity
@Table(name = "roles")
public class Role {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
@Enumerated(EnumType.STRING)
@Column(length = 20)
private RoleName name;
// 构造函数、getter、setter
}
@Entity
@Table(name = "permissions")
public class Permission {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
@Column(length = 100)
private String name;
@Column(length = 200)
private String description;
// 构造函数、getter、setter
}
@Entity
@Table(name = "role_permissions")
public class RolePermission {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private Long id;
@ManyToOne
@JoinColumn(name = "role_id")
private Role role;
@ManyToOne
@JoinColumn(name = "permission_id")
private Permission permission;
// 构造函数、getter、setter
}
权限服务实现
@Service
@Transactional
public class PermissionService {
@Autowired
private RoleRepository roleRepository;
@Autowired
private UserRepository userRepository;
public boolean hasPermission(String username, String permissionName) {
User user = userRepository.findByUsername(username)
.orElseThrow(() -> new UsernameNotFoundException("User not found"));
return user.getRoles().stream()
.flatMap(role -> role.getRolePermissions().stream())
.map(RolePermission::getPermission)
.anyMatch(permission -> permission.getName().equals(permissionName));
}
public boolean hasAnyRole(String username, List<String> roles) {
User user = userRepository.findByUsername(username)
.orElseThrow(() -> new UsernameNotFoundException("User not found"));
return user.getRoles().stream()
.map(Role::getName)
.anyMatch(roleName -> roles.contains(roleName.toString()));
}
public Set<Permission> getUserPermissions(String username) {
User user = userRepository.findByUsername(username)
.orElseThrow(() -> new UsernameNotFoundException("User not found"));
return user.getRoles().stream()
.flatMap(role -> role.getRolePermissions().stream())
.map(RolePermission::getPermission)
.collect(Collectors.toSet());
}
}
基于方法的权限控制
@PreAuthorize("hasRole('ADMIN')")
@RequestMapping("/admin")
public class AdminController {
@GetMapping("/dashboard")
public ResponseEntity<String> getDashboard() {
return ResponseEntity.ok("Admin Dashboard");
}
@PostMapping("/user/create")
@PreAuthorize("hasPermission('USER_CREATE')")
public ResponseEntity<String> createUser(@RequestBody User user) {
return ResponseEntity.ok("User created successfully");
}
}
@PreAuthorize("hasAnyRole('ADMIN', 'MANAGER')")
@RequestMapping("/manager")
public class ManagerController {
@GetMapping("/reports")
public ResponseEntity<List<Report>> getReports() {
return ResponseEntity.ok(reportService.getReports());
}
}
完整的安全配置类
@Configuration
@EnableWebSecurity
@EnableMethodSecurity(prePostEnabled = true)
public class SecurityConfig {
@Autowired
private JwtAuthenticationFilter jwtAuthenticationFilter;
@Autowired
private UserDetailsService userDetailsService;
@Bean
public PasswordEncoder passwordEncoder() {
return new BCryptPasswordEncoder();
}
@Bean
public AuthenticationManager authenticationManager(
AuthenticationConfiguration authConfig) throws Exception {
return authConfig.getAuthenticationManager();
}
@Bean
public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
http.cors().and().csrf().disable()
.exceptionHandling()
.and()
.sessionManagement()
.sessionCreationPolicy(SessionCreationPolicy.STATELESS)
.and()
.authorizeHttpRequests(authz -> authz
.requestMatchers("/api/auth/**").permitAll()
.requestMatchers("/api/public/**").permitAll()
.requestMatchers("/api/admin/**").hasRole("ADMIN")
.anyRequest().authenticated()
);
http.addFilterBefore(jwtAuthenticationFilter, UsernamePasswordAuthenticationFilter.class);
return http.build();
}
@Bean
public CorsConfigurationSource corsConfigurationSource() {
CorsConfiguration configuration = new CorsConfiguration();
configuration.setAllowedOriginPatterns(Arrays.asList("*"));
configuration.setAllowedMethods(Arrays.asList("GET", "POST", "PUT", "DELETE"));
configuration.setAllowedHeaders(Arrays.asList("*"));
configuration.setAllowCredentials(true);
UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
source.registerCorsConfiguration("/**", configuration);
return source;

}
实际应用场景
用户认证流程
@RestController
@RequestMapping("/api/auth")
public class AuthController {
@Autowired
private AuthenticationManager authenticationManager;
@Autowired
private JwtConfig jwtConfig;
@Autowired
private UserService userService;
@PostMapping("/login")
public ResponseEntity<?> login(@RequestBody LoginRequest loginRequest) {
try {
Authentication authentication = authenticationManager.authenticate(
new UsernamePasswordAuthenticationToken(
loginRequest.getUsername(),
loginRequest.getPassword()
)
);
SecurityContextHolder.getContext().setAuthentication(authentication);
String jwt = jwtConfig.generateToken((UserDetails) authentication.getPrincipal());
return ResponseEntity.ok(new JwtResponse(jwt));
} catch (AuthenticationException e) {
return ResponseEntity.status(HttpStatus.UNAUTHORIZED)
.body("用户名或密码错误");
}
}
@PostMapping("/register")
public ResponseEntity<?> register(@RequestBody RegisterRequest registerRequest) {
if (userService.existsByUsername(registerRequest.getUsername())) {
return ResponseEntity.badRequest()
.body("用户名已存在");
}
User user = userService.createUser(registerRequest);
return ResponseEntity.ok("用户注册成功");
}
}
OAuth2认证端点
@RestController
public class OAuth2Controller {
@GetMapping("/oauth2/authorization/{clientRegistrationId}")
public void authorizeClient(@PathVariable String clientRegistrationId,
HttpServletRequest request,
HttpServletResponse response) throws IOException {
// 处理OAuth2授权请求
String redirectUri = "http://localhost:8080/login/oauth2/code/client";
// 实现具体的授权逻辑
}
@GetMapping("/oauth2/callback")
public ResponseEntity<?> handleCallback(@RequestParam String code,
@RequestParam String state) {
// 处理OAuth2回调
return ResponseEntity.ok("OAuth2认证成功");
}
}
安全最佳实践
密码安全策略
@Configuration
public class PasswordSecurityConfig {
@Bean
public PasswordEncoder passwordEncoder() {
// 使用BCrypt加密，强度为12
return new BCryptPasswordEncoder(12);
}
@Bean
public DelegatingPasswordEncoder passwordEncoder() {
Map<String, PasswordEncoder> encoders = new HashMap<>();
encoders.put("bcrypt", new BCryptPasswordEncoder());
encoders.put("noop", NoOpPasswordEncoder.getInstance());
return new DelegatingPasswordEncoder("bcrypt", encoders);
}
}
安全头配置
@Bean
public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
http.headers().frameOptions().deny();
http.headers().xssProtection().enable();
http.headers().contentTypeOptions().disable();
// 设置安全头
http.headers(headers -> headers
.httpStrictTransportSecurity(hsts -> hsts
.maxAgeInSeconds(31536000)
.includeSubdomains(true)
.preload(true)
)
.frameOptions(frameOptions -> frameOptions
.deny()
)
.contentTypeOptions(contentTypeOptions -> contentTypeOptions
.disable()
)
);
return http.build();
}
性能优化建议
缓存策略
@Service
public class CachedPermissionService {
@Autowired
private PermissionService permissionService;
@Cacheable(value = "userPermissions", key = "#username")
public Set<Permission> getUserPermissions(String username) {
return permissionService.getUserPermissions(username);
}
@CacheEvict(value = "userPermissions", key = "#username")
public void invalidateUserPermissions(String username) {
// 清除缓存
}
}
JWT令牌刷新机制
@RestController
@RequestMapping("/api/auth")
public class RefreshTokenController {
@PostMapping("/refresh")
public ResponseEntity<?> refreshToken(@RequestBody RefreshTokenRequest request) {
try {
String refreshToken = request.getRefreshToken();
// 验证刷新令牌
String newJwtToken = jwtConfig.refreshToken(refreshToken);
return ResponseEntity.ok(new JwtResponse(newJwtToken));
} catch (Exception e) {
return ResponseEntity.status(HttpStatus.UNAUTHORIZED)
.body("刷新令牌无效");
}
}
}
