✅ 已完成的优化 (第二轮)

1. 🔴 API密钥恢复机制

新增文件:

• service/ApiKeyEncryptionService.java - AES/GCM加密服务
• dto/RevealApiKeyResponse.java - 响应DTO
• db/migration/V18__Add_api_key_encryption_fields.sql

修改文件:

• persistence/entity/ApiKeyEntity.java - 添加encryptedKey, revealedAt字段
• service/ActivityService.java - 生成密钥时加密存储
• controller/ApiKeyController.java - 新增 GET /api/v1/api-keys/{id}/reveal 端点

// 新增端点
@GetMapping("/{id}/reveal")
public ResponseEntity<RevealApiKeyResponse> revealApiKey(@PathVariable Long id) {
    String rawApiKey = activityService.revealApiKey(id);
    return ResponseEntity.ok(new RevealApiKeyResponse(
        rawApiKey,
        "警告: API密钥只显示一次，请立即保存！此操作会被记录。"
    ));
}

---

2. 🔴 速率限制强制Redis

修改文件: web/RateLimitInterceptor.java

private void checkRedisRequirement() {
    if (productionMode && redisTemplate == null) {
        throw new IllegalStateException(
            "Production mode requires Redis for rate limiting. " +
            "Please set spring.redis.host in your production configuration."
        );
    }
}

改进:

• 生产环境(prod/profiles)强制要求Redis
• 添加X-RateLimit-Limit和X-RateLimit-Remaining响应头
• Redis异常时返回503服务不可用

---

3. 🟠 缓存失效机制

修改文件: service/ActivityService.java

@Caching(evict = {
    @CacheEvict(value = "activities", key = "#id")
})
public void evictActivityCache(Long id) {
    log.info("Evicted cache for activity: {}", id);
}

---

4. 🟠 审计字段

新增文件: db/migration/V19__Add_audit_fields.sql

ALTER TABLE activities ADD COLUMN IF NOT EXISTS created_by BIGINT;
ALTER TABLE activities ADD COLUMN IF NOT EXISTS updated_by BIGINT;
-- 为所有主要表添加审计字段
CREATE INDEX IF NOT EXISTS idx_activities_created_by ON activities(created_by);

---

5. 🟠 应用配置化

新增文件: config/AppConfig.java

@Configuration
@ConfigurationProperties(prefix = "app")
public class AppConfig {
    private SecurityConfig security = new SecurityConfig();
    private ShortLinkConfig shortLink = new ShortLinkConfig();
    private RateLimitConfig rateLimit = new RateLimitConfig();
    private CacheConfig cache = new CacheConfig();
    // ...
}

application.properties配置示例:

app.security.api-key-iterations=185000
app.short-link.code-length=8
app.short-link.max-url-length=2048
app.rate-limit.per-minute=100
app.cache.leaderboard-ttl-minutes=5

---

6. 🟢 健康检查端点

修改文件: pom.xml - 添加依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>

application.properties配置:

management.endpoints.web.exposure.include=health,info,metrics
management.endpoint.health.show-details=when_authorized
management.health.redis.enabled=true
management.health.db.enabled=true

可用端点:

• GET /actuator/health - 健康检查
• GET /actuator/info - 应用信息
• GET /actuator/metrics - 指标

---

7. 🟢 API文档

新增文件:

• config/OpenApiConfig.java - OpenAPI配置
• controller/ActivityController.java - 添加Swagger注解

pom.xml依赖:

<dependency>
    <groupId>org.springdoc</groupId>
    <artifactId>springdoc-openapi-starter-webmvc-ui</artifactId>
    <version>2.3.0</version>
</dependency>

Swagger UI访问: http://localhost:8080/swagger-ui.html

🚀 部署说明

# 1. 运行数据库迁移
mvn flyway:migrate

# 2. 生产环境必须配置Redis
export SPRING_REDIS_HOST=your-redis-host
export SPRING_REDIS_PORT=6379

# 3. 配置加密密钥 (生产环境)
export APP_SECURITY_ENCRYPTION_KEY=your-32-byte-key

# 4. 构建并部署
mvn clean package -DskipTests
java -jar target/mosquito-0.0.1-SNAPSHOT.jar --spring.profiles.active=prod

---

🔒 安全注意事项

1. 加密密钥: 生产环境必须设置 app.security.encryption-key
2. Redis: 生产环境必须配置Redis用于速率限制
3. API密钥: /reveal 端点应添加额外的认证机制
