OAuth2与JWT核心概念解析

OAuth2协议框架

OAuth2（开放授权2.0）是一个基于令牌的认证授权协议，其核心角色包括：

mermaid

OAuth2支持四种授权模式，适用于不同场景：

授权模式	适用场景	安全性	实现复杂度
授权码模式	第三方应用	高	中
密码模式	内部系统	中	低
客户端模式	服务间通信	低	低
简化模式	前端应用	低	中

JWT数据结构

JWT（JSON Web Token）是一种轻量级的令牌格式，由三部分组成：

eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkiLCJuYW1lIjoiSm9obiBEb2UifQ.SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c

Header（头部）：指定加密算法

{
  "alg": "HS256",
  "typ": "JWT"
}

Payload（载荷）：存储声明信息

{
  "sub": "123456789",
  "name": "John Doe",
  "iat": 1516239022,
  "exp": 1516242622
}

Signature（签名）：防止令牌被篡改

HMACSHA256(
  base64UrlEncode(header) + "." +
  base64UrlEncode(payload),
  secret
)

    implementation 'org.springframework:spring-web:5.3.14'
}

OAuth2授权服务器配置

授权码模式实现

AuthorizationServerConfig.java

@Configuration
@EnableAuthorizationServer
public class AuthorizationServerConfig extends AuthorizationServerConfigurerAdapter {

    @Autowired
    private AuthenticationManager authenticationManager;
    
    @Autowired
    private UserDetailsService userDetailsService;
    
    @Value("${jwt.secret}")
    private String jwtSecret;

    @Override
    public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
        clients.inMemory()
            // 客户端配置
            .withClient("web-client")
            .secret(passwordEncoder.encode("secret"))
            .authorizedGrantTypes("authorization_code", "refresh_token")
            .scopes("read", "write")
            .redirectUris("http://localhost:8080/login/oauth2/code/web-client")
            .accessTokenValiditySeconds(3600)
            .refreshTokenValiditySeconds(86400);
    }

    @Override
    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
        endpoints
            .authenticationManager(authenticationManager)
            .userDetailsService(userDetailsService)
            .accessTokenConverter(jwtAccessTokenConverter());
    }

    @Bean
    public JwtAccessTokenConverter jwtAccessTokenConverter() {
        JwtAccessTokenConverter converter = new JwtAccessTokenConverter();
        converter.setSigningKey(jwtSecret);
        return converter;
    }
    
    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }
}

密码模式配置

添加密码授权类型

@Override
public void configure(ClientDetailsServiceConfigurer clients) throws Exception {
    clients.inMemory()
        .withClient("mobile-client")
        .secret(passwordEncoder.encode("mobile-secret"))
        .authorizedGrantTypes("password", "refresh_token") // 添加密码模式
        .scopes("read")
        .accessTokenValiditySeconds(1800);
}

JWT令牌配置与安全增强

JWT令牌定制

CustomJwtTokenEnhancer.java

@Component
public class CustomJwtTokenEnhancer implements TokenEnhancer {

    @Override
    public OAuth2AccessToken enhance(OAuth2AccessToken accessToken, OAuth2Authentication authentication) {
        Map<String, Object> additionalInfo = new HashMap<>();
        
        // 添加自定义声明
        UserDetails userDetails = (UserDetails) authentication.getPrincipal();
        additionalInfo.put("username", userDetails.getUsername());
        additionalInfo.put("authorities", userDetails.getAuthorities().stream()
                .map(GrantedAuthority::getAuthority)
                .collect(Collectors.toList()));
        
        // 添加时间戳
        additionalInfo.put("issued_at", System.currentTimeMillis());
        
        ((DefaultOAuth2AccessToken) accessToken).setAdditionalInformation(additionalInfo);
        return accessToken;
    }
}

集成令牌增强器

@Bean
public TokenEnhancerChain tokenEnhancerChain() {
    TokenEnhancerChain chain = new TokenEnhancerChain();
    chain.setTokenEnhancers(Arrays.asList(customJwtTokenEnhancer, jwtAccessTokenConverter()));
    return chain;
}

@Override
public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {
    endpoints
        .authenticationManager(authenticationManager)
        .userDetailsService(userDetailsService)
        .accessTokenConverter(jwtAccessTokenConverter())
        .tokenEnhancer(tokenEnhancerChain()); // 添加令牌增强器
}

JWT安全最佳实践

使用非对称加密算法

@Bean
public JwtAccessTokenConverter jwtAccessTokenConverter() {
    JwtAccessTokenConverter converter = new JwtAccessTokenConverter();
    Resource resource = new ClassPathResource("jwt-public-key.pem");
    try (InputStream inputStream = resource.getInputStream()) {
        converter.setVerifierKey(IOUtils.toString(inputStream, StandardCharsets.UTF_8));
    } catch (IOException e) {
        throw new RuntimeException(e);
    }
    return converter;
}

令牌存储安全

// 前端存储示例 - 使用HttpOnly Cookie
response.addHeader("Set-Cookie", "access_token=" + token + "; HttpOnly; Secure; SameSite=Strict; Path=/");

敏感信息过滤

// 移除JWT中的敏感信息
additionalInfo.remove("password");
additionalInfo.remove("social_security_number");

资源服务器配置

JWT令牌验证

ResourceServerConfig.java

@Configuration
@EnableResourceServer
public class ResourceServerConfig extends ResourceServerConfigurerAdapter {

    @Value("${jwt.public-key}")
    private String publicKey;

    @Override
    public void configure(ResourceServerSecurityConfigurer resources) throws Exception {
        resources
            .resourceId("api-resources")
            .tokenStore(tokenStore());
    }

    @Override
    public void configure(HttpSecurity http) throws Exception {
        http
            .authorizeRequests()
            .antMatchers("/api/public/**").permitAll()
            .antMatchers("/api/user/**").hasRole("USER")
            .antMatchers("/api/admin/**").hasRole("ADMIN")
            .anyRequest().authenticated();
    }

    @Bean
    public TokenStore tokenStore() {
        return new JwtTokenStore(jwtAccessTokenConverter());
    }

    @Bean
    public JwtAccessTokenConverter jwtAccessTokenConverter() {
        JwtAccessTokenConverter converter = new JwtAccessTokenConverter();
        converter.setVerifierKey(publicKey);
        return converter;
    }
}

分布式系统中的令牌传递

配置RestTemplate传递令牌

@Bean
public RestTemplate oauth2RestTemplate(OAuth2ClientContext oauth2ClientContext,
                                      OAuth2ProtectedResourceDetails resourceDetails) {
    return new OAuth2RestTemplate(resourceDetails, oauth2ClientContext);
}

服务间调用示例

@Service
public class OrderService {

    @Autowired
    private RestTemplate oauth2RestTemplate;

    public UserDto getUserInfo(Long userId) {
        return oauth2RestTemplate.getForObject(
            "http://user-service/api/users/" + userId, 
            UserDto.class
        );
    }
}

Spring Security集成与权限控制

安全配置类

SecurityConfig.java

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Autowired
    private UserDetailsService userDetailsService;

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(userDetailsService)
            .passwordEncoder(passwordEncoder());
    }

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http
            .csrf().disable()
            .authorizeRequests()
            .antMatchers("/oauth/**").permitAll()
            .anyRequest().authenticated()
            .and()
            .formLogin().permitAll();
    }

    @Bean
    @Override
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }
    
    @Bean
    public PasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }
}

方法级权限控制

使用注解实现细粒度权限控制

@RestController
@RequestMapping("/api/orders")
public class OrderController {

    @PreAuthorize("hasRole('ADMIN') or @orderSecurityService.isOwner(#orderId, principal.username)")
    @GetMapping("/{orderId}")
    public OrderDto getOrder(@PathVariable Long orderId) {
        // 业务逻辑
    }
    
    @PreAuthorize("hasPermission(#order, 'WRITE')")
    @PutMapping
    public OrderDto updateOrder(@RequestBody OrderDto order) {
        // 业务逻辑
    }
}

前端集成与令牌管理

React应用集成示例

OAuth2授权流程

// login.js
const loginWithOAuth2 = () => {
  const clientId = "web-client";
  const redirectUri = "http://localhost:3000/callback";
  const scope = "read write";
  const authUrl = `http://localhost:8080/oauth/authorize?client_id=${clientId}&redirect_uri=${redirectUri}&response_type=code&scope=${scope}`;
  
  window.location.href = authUrl;
};

// callback.js
const handleCallback = async () => {
  const code = new URLSearchParams(window.location.search).get('code');
  
  // 交换令牌
  const tokenResponse = await fetch('http://localhost:8080/oauth/token', {
    method: 'POST',
    headers: {
      'Content-Type': 'application/x-www-form-urlencoded',
      'Authorization': 'Basic ' + btoa('web-client:secret')
    },
    body: new URLSearchParams({
      grant_type: 'authorization_code',
      code: code,
      redirect_uri: 'http://localhost:3000/callback'
    })
  });
  
  const { access_token, refresh_token } = await tokenResponse.json();
  
  // 存储令牌
  localStorage.setItem('access_token', access_token);
  localStorage.setItem('refresh_token', refresh_token);
  
  // 重定向到主页
  window.location.href = '/';
};

令牌刷新机制

自动刷新令牌实现

// api-client.js
const apiClient = axios.create({
  baseURL: 'http://localhost:8080/api'
});

// 请求拦截器添加令牌
apiClient.interceptors.request.use(config => {
  const token = localStorage.getItem('access_token');
  if (token) {
    config.headers.Authorization = `Bearer ${token}`;
  }
  return config;
});

// 响应拦截器处理令牌过期
apiClient.interceptors.response.use(
  response => response,
  async error => {
    const originalRequest = error.config;
    
    // 如果是401错误且未尝试刷新
    if (error.response.status === 401 && !originalRequest._retry) {
      originalRequest._retry = true;
      
      try {
        // 刷新令牌
        const refreshToken = localStorage.getItem('refresh_token');
        const response = await axios.post('http://localhost:8080/oauth/token', {
          grant_type: 'refresh_token',
          refresh_token: refreshToken
        }, {
          headers: {
            'Authorization': 'Basic ' + btoa('web-client:secret')
          }
        });
        
        // 更新存储的令牌
        const { access_token } = response.data;
        localStorage.setItem('access_token', access_token);
        
        // 重试原始请求
        originalRequest.headers.Authorization = `Bearer ${access_token}`;
        return apiClient(originalRequest);
      } catch (refreshError) {
        // 刷新令牌失败，需要重新登录
        localStorage.removeItem('access_token');
        localStorage.removeItem('refresh_token');
        window.location.href = '/login';
        return Promise.reject(refreshError);
      }
    }
    
    return Promise.reject(error);
  }
);

安全漏洞防御与最佳实践

常见安全问题及解决方案

安全风险	防御措施	实现示例
令牌劫持	使用HTTPS + HttpOnly Cookie	`response.addHeader("Set-Cookie", "token=...; HttpOnly; Secure")`
重放攻击	添加jti声明 + 令牌黑名单	`additionalInfo.put("jti", UUID.randomUUID().toString())`
权限越界	细粒度RBAC控制	`@PreAuthorize("hasPermission(#resourceId, 'Resource', 'READ')")`
注入攻击	输入验证 + 参数绑定	`@Valid @RequestBody UserDto user`

安全审计与监控

配置审计日志

@Configuration
@EnableAuditing
public class AuditConfig {

    @Bean
    public AuditorAware<String> auditorProvider() {
        return () -> Optional.ofNullable(SecurityContextHolder.getContext().getAuthentication())
                .map(Authentication::getName);
    }
}

// 实体类审计
@Entity
@Audited
public class Order {
    @Id
    private Long id;
    
    private String productName;
    
    @CreatedBy
    private String createdBy;
    
    @CreatedDate
    private LocalDateTime createdDate;
    
    @LastModifiedBy
    private String lastModifiedBy;
    
    @LastModifiedDate
    private LocalDateTime lastModifiedDate;
}

部署与测试策略

多环境配置管理

application.yml

spring:
  profiles:
    active: dev

---
spring:
  profiles: dev
jwt:
  secret: dev-secret-key-for-development-only
  public-key: |
    -----BEGIN PUBLIC KEY-----
    MIIBIjANBgkqhkiG9w0BAQEFAAOCAQ8AMIIBCgKCAQEA...
    -----END PUBLIC KEY-----

---
spring:
  profiles: prod
jwt:
  secret: ${JWT_SECRET}  # 从环境变量获取
  public-key: ${JWT_PUBLIC_KEY}

集成测试示例

OAuth2IntegrationTest.java

@SpringBootTest
@AutoConfigureMockMvc
public class OAuth2IntegrationTest {

    @Autowired
    private MockMvc mockMvc;
    
    @Autowired
    private ObjectMapper objectMapper;

    private String accessToken;
    
    @BeforeEach
    public void setup() throws Exception {
        // 获取令牌
        String response = mockMvc.perform(post("/oauth/token")
                .param("grant_type", "password")
                .param("username", "testuser")
                .param("password", "password")
                .header("Authorization", "Basic " + Base64.getEncoder().encodeToString("mobile-client:mobile-secret".getBytes())))
                .andExpect(status().isOk())
                .andReturn()
                .getResponse()
                .getContentAsString();
                
        accessToken = objectMapper.readTree(response).get("access_token").asText();
    }
    
    @Test
    public void testAuthorizedApiAccess() throws Exception {
        mockMvc.perform(get("/api/user/profile")
                .header("Authorization", "Bearer " + accessToken))
                .andExpect(status().isOk())
                .andExpect(jsonPath("$.username").value("testuser"));
    }
    
    @Test
    public void testUnauthorizedAccess() throws Exception {
        mockMvc.perform(get("/api/admin/stats"))
                .andExpect(status().isUnauthorized());
    }
}
