test(cache): 修复CacheConfigTest边界值测试
- 修改 shouldVerifyCacheManager_withMaximumIntegerTtl 为 shouldVerifyCacheManager_withMaximumAllowedTtl - 使用正确的最大TTL值（10080分钟，7天）而不是 Integer.MAX_VALUE - 新增 shouldThrowException_whenTtlExceedsMaximum 测试验证边界检查 - 所有1266个测试用例通过 - 覆盖率: 指令81.89%, 行88.48%, 分支51.55% docs: 添加项目状态报告 - 生成 PROJECT_STATUS_REPORT.md 详细记录项目当前状态 - 包含质量指标、已完成功能、待办事项和技术债务

# 🦟 蚊子项目优化报告
|
||||
|
||||
**优化日期**: 2026-01-20
|
||||
**基于**: CODE_REVIEW_REPORT.md
|
||||
**工具**: superpowers, security, code-review skills
|
||||
|

|
||||
|
||||
## ✅ 已完成的优化
|
||||
|
||||
### 1. 🔴 SSRF漏洞修复 (Critical)
|
||||
|
||||
**新增文件**: `src/main/java/com/mosquito/project/web/UrlValidator.java`
|
||||
|
||||
```java
|
||||
@Component
|
||||
public class UrlValidator {
|
||||
public boolean isAllowedUrl(String url) {
|
||||
// 验证URL协议只允许 http/https
|
||||
// 阻止内部IP访问 (10.x, 172.16-31.x, 192.168.x)
|
||||
// 阻止 localhost 变体
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**修改文件**: `ShortLinkController.java`
|
||||
- 添加URL验证逻辑
|
||||
- 修复X-Forwarded-For头处理（取第一个IP）
|
||||
- 替换静默异常为日志记录
|
||||
|
||||
```java
|
||||
@GetMapping("/r/{code}")
|
||||
public ResponseEntity<Void> redirect(@PathVariable String code, HttpServletRequest request) {
|
||||
// 1. URL白名单验证
|
||||
if (!urlValidator.isAllowedUrl(originalUrl)) {
|
||||
log.warn("Blocked malicious redirect: {}", originalUrl);
|
||||
return ResponseEntity.status(HttpStatus.BAD_REQUEST).build();
|
||||
}
|
||||
// 2. X-Forwarded-For 取第一个IP
|
||||
String ip = request.getHeader("X-Forwarded-For");
|
||||
if (ip != null && !ip.isBlank()) {
|
||||
ip = ip.split(",")[0].trim();
|
||||
}
|
||||
// 3. 异常日志记录
|
||||
} catch (Exception ex) {
|
||||
log.error("Failed to record link click: {}", ex.getMessage(), ex);
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 2. 🟠 输入验证增强 (Medium)
|
||||
|
||||
**修改文件**: `ShortenRequest.java`
|
||||
|
||||
```java
|
||||
public class ShortenRequest {
|
||||
@NotBlank(message = "原始URL不能为空")
|
||||
@Size(min = 10, max = 2048, message = "URL长度必须在10-2048个字符之间")
|
||||
private String originalUrl;
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 3. 🟡 数据库完整性 (Medium)
|
||||
|
||||
**新增文件**: `db/migration/V17__Add_foreign_key_constraints.sql`
|
||||
|
||||
```sql
|
||||
-- 添加外键约束
|
||||
ALTER TABLE api_keys
|
||||
ADD CONSTRAINT fk_api_keys_activity
|
||||
FOREIGN KEY (activity_id) REFERENCES activities(id)
|
||||
ON DELETE SET NULL;
|
||||
|
||||
ALTER TABLE short_links
|
||||
ADD CONSTRAINT fk_short_links_activity
|
||||
FOREIGN KEY (activity_id) REFERENCES activities(id)
|
||||
ON DELETE SET NULL;
|
||||
|
||||
-- 添加查询优化索引
|
||||
CREATE INDEX IF NOT EXISTS idx_user_invites_activity_invitee
|
||||
ON user_invites(activity_id, invitee_user_id);
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 4. 🔒 缓存序列化安全 (Medium)
|
||||
|
||||
**修改文件**: `CacheConfig.java`
|
||||
|
||||
```java
|
||||
@Bean
|
||||
public RedisCacheManager cacheManager(RedisConnectionFactory connectionFactory) {
|
||||
ObjectMapper objectMapper = new ObjectMapper();
|
||||
objectMapper.activateDefaultTyping(
|
||||
LaissezFaireSubTypeValidator.instance,
|
||||
ObjectMapper.DefaultTyping.NON_FINAL,
|
||||
JsonTypeInfo.As.PROPERTY
|
||||
);
|
||||
|
||||
RedisCacheConfiguration defaultConfig = RedisCacheConfiguration.defaultCacheConfig()
|
||||
.entryTtl(Duration.ofMinutes(5))
|
||||
.serializeValuesWith(RedisSerializationContext.SerializationPair.fromSerializer(
|
||||
new GenericJackson2JsonRedisSerializer(objectMapper)
|
||||
))
|
||||
.disableCachingNullValues()
|
||||
.prefixCacheNameWith("mosquito:");
|
||||
}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### 5. ⚙️ 应用配置增强 (Low)
|
||||
|
||||
**修改文件**: `application.properties`
|
||||
|
||||
```properties
|
||||
# Database Connection Pool (HikariCP)
|
||||
spring.datasource.hikari.maximum-pool-size=20
|
||||
spring.datasource.hikari.minimum-idle=5
|
||||
spring.datasource.hikari.connection-timeout=30000
|
||||
spring.datasource.hikari.idle-timeout=600000
|
||||
spring.datasource.hikari.max-lifetime=1800000
|
||||
spring.datasource.hikari.pool-name=MosquitoHikariPool
|
||||
|
||||
# Application Configuration
|
||||
app.rate-limit.per-minute=100
|
||||
app.short-link.code-length=8
|
||||
app.short-link.max-url-length=2048
|
||||
app.security.api-key-iterations=185000
|
||||
|
||||
# Logging Configuration
|
||||
logging.level.com.mosquito.project.web=DEBUG
|
||||
```

||||

|
||||
## 🧪 测试验证
|
||||
|
||||
```bash
|
||||
# 运行ShortLinkController测试
|
||||
mvn test -Dtest=ShortLinkControllerTest
|
||||
|
||||
# 结果: 4/4 tests passed
|
||||
# - shouldCreateShortLink_andReturn201
|
||||
# - shouldRedirect_whenCodeExists
|
||||
# - should404_whenCodeNotFound
|
||||
# - shouldBlockMaliciousUrl (新增)
|
||||
```
|
||||

|
||||
|
||||
## 🚀 下一步建议
|
||||
|
||||
### 还需要修复的问题 (未包含在本次优化中)
|
||||
|
||||
1. **API密钥恢复机制** - 实现加密存储和重新显示功能
|
||||
2. **速率限制强制Redis** - 生产环境必须使用Redis
|
||||
3. **缓存失效机制** - 添加@CacheEvict注解
|
||||
4. **API版本控制** - 实现v2版本API
|
||||
|
||||
### 部署注意事项
|
||||
|
||||
```bash
|
||||
# 1. 运行数据库迁移
|
||||
mvn flyway:migrate
|
||||
|
||||
# 2. 更新配置 (生产环境)
|
||||
# 设置 REDIS_HOST 环境变量
|
||||
# 配置数据库连接池参数
|
||||
|
||||
# 3. 构建并部署
|
||||
mvn clean package -DskipTests
|
||||
java -jar target/mosquito-0.0.1-SNAPSHOT.jar
|
||||
```
