## 优化方案设计 |
|||
|
|||
### 1. 数据库连接优化 |
|||
|
|||
#### 连接池配置改进 |
|||
```javascript |
|||
// knexfile.mjs 优化配置 |
|||
export default { |
|||
development: { |
|||
client: "sqlite3", |
|||
connection: { |
|||
filename: "./database/development.sqlite3", |
|||
}, |
|||
pool: { |
|||
min: 1, |
|||
max: 3, // 适当增加连接数 |
|||
acquireTimeoutMillis: 60000, |
|||
createTimeoutMillis: 30000, |
|||
destroyTimeoutMillis: 5000, |
|||
idleTimeoutMillis: 30000, |
|||
reapIntervalMillis: 1000, |
|||
createRetryIntervalMillis: 200, |
|||
afterCreate: (conn, done) => { |
|||
conn.run("PRAGMA journal_mode = WAL", done) |
|||
conn.run("PRAGMA synchronous = NORMAL", done) |
|||
conn.run("PRAGMA cache_size = 1000", done) |
|||
conn.run("PRAGMA temp_store = MEMORY", done) |
|||
}, |
|||
}, |
|||
} |
|||
} |
|||
``` |
|||
|
|||
#### 健康检查机制 |
|||
```javascript |
|||
// db/index.js 添加健康检查 |
|||
export const checkHealth = async () => { |
|||
try { |
|||
await db.raw("SELECT 1") |
|||
return { status: "healthy", timestamp: new Date() } |
|||
} catch (error) { |
|||
return { status: "unhealthy", error: error.message, timestamp: new Date() } |
|||
} |
|||
} |
|||
``` |
|||
|
|||
### 2. 模型设计优化 |
|||
|
|||
#### 统一基础模型类 |
|||
```javascript |
|||
// db/models/BaseModel.js |
|||
class BaseModel { |
|||
static get tableName() { |
|||
throw new Error("tableName must be defined") |
|||
} |
|||
|
|||
static async findById(id) { |
|||
const result = await db(this.tableName).where("id", id).first() |
|||
return result || null |
|||
} |
|||
|
|||
static async findAll(options = {}) { |
|||
const { page = 1, limit = 10, orderBy = "id", order = "desc" } = options |
|||
const offset = (page - 1) * limit |
|||
|
|||
return db(this.tableName) |
|||
.orderBy(orderBy, order) |
|||
.limit(limit) |
|||
.offset(offset) |
|||
} |
|||
|
|||
static async create(data) { |
|||
const [result] = await db(this.tableName) |
|||
.insert({ |
|||
...data, |
|||
created_at: db.fn.now(), |
|||
updated_at: db.fn.now(), |
|||
}) |
|||
.returning("*") |
|||
return result |
|||
} |
|||
|
|||
static async update(id, data) { |
|||
const [result] = await db(this.tableName) |
|||
.where("id", id) |
|||
.update({ |
|||
...data, |
|||
updated_at: db.fn.now(), |
|||
}) |
|||
.returning("*") |
|||
return result |
|||
} |
|||
|
|||
static async delete(id) { |
|||
return db(this.tableName).where("id", id).del() |
|||
} |
|||
|
|||
static async count(conditions = {}) { |
|||
const result = await db(this.tableName).where(conditions).count("id as count").first() |
|||
return parseInt(result.count) |
|||
} |
|||
} |
|||
``` |
|||
|
|||
#### 关联查询方法 |
|||
```javascript |
|||
// 扩展模型关联查询 |
|||
class ArticleModel extends BaseModel { |
|||
static get tableName() { return "articles" } |
|||
|
|||
// 获取作者相关文章 |
|||
static async findByAuthorWithProfile(author) { |
|||
return db(this.tableName) |
|||
.select("articles.*", "users.name as author_name", "users.avatar as author_avatar") |
|||
.leftJoin("users", "articles.author", "users.username") |
|||
.where("articles.author", author) |
|||
.where("articles.status", "published") |
|||
} |
|||
} |
|||
|
|||
class BookmarkModel extends BaseModel { |
|||
static get tableName() { return "bookmarks" } |
|||
|
|||
// 获取用户书签（包含用户信息） |
|||
static async findByUserWithProfile(userId) { |
|||
return db(this.tableName) |
|||
.select("bookmarks.*", "users.username", "users.name") |
|||
.leftJoin("users", "bookmarks.user_id", "users.id") |
|||
.where("bookmarks.user_id", userId) |
|||
} |
|||
} |
|||
``` |
|||
|
|||
### 3. 查询缓存优化 |
|||
|
|||
#### 改进缓存键生成策略 |
|||
```javascript |
|||
// db/index.js 缓存优化 |
|||
const getCacheKeyForBuilder = (builder) => { |
|||
if (builder._customCacheKey) return String(builder._customCacheKey) |
|||
|
|||
// 改进键生成策略 |
|||
const sql = builder.toString() |
|||
const tableName = builder._single.table || 'unknown' |
|||
const hash = require('crypto').createHash('md5').update(sql).digest('hex') |
|||
|
|||
return `${tableName}:${hash}` |
|||
} |
|||
|
|||
// 添加缓存统计 |
|||
export const getCacheStats = () => { |
|||
let valid = 0 |
|||
let expired = 0 |
|||
let totalSize = 0 |
|||
|
|||
for (const [key, entry] of queryCache.entries()) { |
|||
if (isExpired(entry)) { |
|||
expired++ |
|||
} else { |
|||
valid++ |
|||
totalSize += JSON.stringify(entry.value).length |
|||
} |
|||
} |
|||
|
|||
return { |
|||
totalKeys: queryCache.size, |
|||
validKeys: valid, |
|||
expiredKeys: expired, |
|||
totalSize, |
|||
hitRate: valid / (valid + expired) || 0 |
|||
} |
|||
} |
|||
``` |
|||
|
|||
#### 缓存一致性策略 |
|||
```javascript |
|||
// 数据变更时自动清理相关缓存 |
|||
buildKnex.QueryBuilder.extend("invalidateCache", function() { |
|||
const tableName = this._single.table |
|||
if (tableName) { |
|||
DbQueryCache.clearByPrefix(`${tableName}:`) |
|||
} |
|||
return this |
|||
}) |
|||
|
|||
// 在模型的 CUD 操作后自动清理缓存 |
|||
class BaseModel { |
|||
static async create(data) { |
|||
const result = await db(this.tableName).insert(data).returning("*") |
|||
await db(this.tableName).invalidateCache() |
|||
return result[0] |
|||
} |
|||
|
|||
static async update(id, data) { |
|||
const result = await db(this.tableName) |
|||
.where("id", id) |
|||
.update(data) |
|||
.returning("*") |
|||
await db(this.tableName).invalidateCache() |
|||
return result[0] |
|||
} |
|||
|
|||
static async delete(id) { |
|||
const result = await db(this.tableName).where("id", id).del() |
|||
await db(this.tableName).invalidateCache() |
|||
return result |
|||
} |
|||
} |
|||
``` |
|||
|
|||
### 4. 事务处理优化 |
|||
|
|||
#### 事务工具函数 |
|||
```javascript |
|||
// db/transaction.js |
|||
export const withTransaction = async (callback) => { |
|||
const trx = await db.transaction() |
|||
try { |
|||
const result = await callback(trx) |
|||
await trx.commit() |
|||
return result |
|||
} catch (error) { |
|||
await trx.rollback() |
|||
throw error |
|||
} |
|||
} |
|||
|
|||
// 使用示例 |
|||
export const createUserWithProfile = async (userData, profileData) => { |
|||
return withTransaction(async (trx) => { |
|||
const [user] = await trx("users").insert(userData).returning("*") |
|||
const [profile] = await trx("user_profiles") |
|||
.insert({ ...profileData, user_id: user.id }) |
|||
.returning("*") |
|||
return { user, profile } |
|||
}) |
|||
} |
|||
``` |
|||
|
|||
#### 批量操作优化 |
|||
```javascript |
|||
// 批量插入优化 |
|||
class BaseModel { |
|||
static async createMany(dataArray, batchSize = 100) { |
|||
const results = [] |
|||
for (let i = 0; i < dataArray.length; i += batchSize) { |
|||
const batch = dataArray.slice(i, i + batchSize) |
|||
const batchResults = await db(this.tableName) |
|||
.insert(batch) |
|||
.returning("*") |
|||
results.push(...batchResults) |
|||
} |
|||
await db(this.tableName).invalidateCache() |
|||
return results |
|||
} |
|||
|
|||
static async updateMany(conditions, data) { |
|||
const result = await db(this.tableName) |
|||
.where(conditions) |
|||
.update({ ...data, updated_at: db.fn.now() }) |
|||
await db(this.tableName).invalidateCache() |
|||
return result |
|||
} |
|||
} |
|||
``` |
|||
|
|||
### 5. 索引优化建议 |
|||
|
|||
#### 添加必要索引 |
|||
```javascript |
|||
// 新增迁移文件：add_performance_indexes.mjs |
|||
export const up = async (knex) => { |
|||
// 用户表索引 |
|||
await knex.schema.alterTable("users", (table) => { |
|||
table.index(["email"]) |
|||
table.index(["username"]) |
|||
table.index(["status", "created_at"]) |
|||
}) |
|||
|
|||
// 文章表索引 |
|||
await knex.schema.alterTable("articles", (table) => { |
|||
table.index(["author", "status"]) |
|||
table.index(["category", "published_at"]) |
|||
table.index(["status", "view_count"]) |
|||
table.index(["tags"]) // 用于标签搜索 |
|||
}) |
|||
|
|||
// 书签表索引 |
|||
await knex.schema.alterTable("bookmarks", (table) => { |
|||
table.index(["user_id", "created_at"]) |
|||
table.index(["url"]) // 用于URL查重 |
|||
}) |
|||
|
|||
// 联系人表索引 |
|||
await knex.schema.alterTable("contacts", (table) => { |
|||
table.index(["email", "created_at"]) |
|||
table.index(["status", "created_at"]) |
|||
}) |
|||
} |
|||
``` |
|||
|
|||
### 6. 错误处理优化 |
|||
|
|||
#### 统一错误处理机制 |
|||
```javascript |
|||
// db/errors.js |
|||
export class DatabaseError extends Error { |
|||
constructor(message, code, originalError) { |
|||
super(message) |
|||
this.name = "DatabaseError" |
|||
this.code = code |
|||
this.originalError = originalError |
|||
} |
|||
} |
|||
|
|||
export const handleDatabaseError = (error) => { |
|||
if (error.code === "SQLITE_CONSTRAINT") { |
|||
return new DatabaseError("数据约束违反", "CONSTRAINT_VIOLATION", error) |
|||
} |
|||
if (error.code === "SQLITE_BUSY") { |
|||
return new DatabaseError("数据库忙，请稍后重试", "DATABASE_BUSY", error) |
|||
} |
|||
return new DatabaseError("数据库操作失败", "DATABASE_ERROR", error) |
|||
} |
|||
|
|||
// 在模型中使用 |
|||
class BaseModel { |
|||
static async findById(id) { |
|||
try { |
|||
return await db(this.tableName).where("id", id).first() |
|||
} catch (error) { |
|||
throw handleDatabaseError(error) |
|||
} |
|||
} |
|||
} |
|||
``` |
|||
|
|||
### 7. 性能监控优化 |
|||
|
|||
#### 查询性能监控 |
|||
```javascript |
|||
// db/monitor.js |
|||
const queryStats = new Map() |
|||
|
|||
export const logQuery = (sql, duration) => { |
|||
const key = sql.split(' ')[0].toUpperCase() // SELECT, INSERT, UPDATE, DELETE |
|||
if (!queryStats.has(key)) { |
|||
queryStats.set(key, { count: 0, totalTime: 0, avgTime: 0 }) |
|||
} |
|||
|
|||
const stats = queryStats.get(key) |
|||

# BaseController 使用指南 |
|||
|
|||
`BaseController` 是项目的基础控制器类，提供了一套完整的 Web 开发常用功能，包括错误处理、参数验证、分页、权限检查等。所有控制器都应该继承此类以保持代码的一致性和可维护性。 |
|||
|
|||
## 特性概览 |
|||
|
|||
- 🛡️ **统一异常处理** - 自动捕获和格式化错误响应 |
|||
- ✅ **参数验证** - 内置常用参数验证规则 |
|||
- 📄 **分页支持** - 标准化分页参数处理 |
|||
- 🔐 **权限控制** - 用户权限和资源所有权检查 |
|||
- 📁 **文件上传** - 文件上传处理助手 |
|||
- 🎨 **响应格式化** - 统一的 JSON 和视图响应 |
|||
|
|||
## 基本用法 |
|||
|
|||
### 1. 继承 BaseController |
|||
|
|||
```javascript |
|||
import BaseController from \"@/base/BaseController.js\" |
|||
import Router from \"utils/router.js\" |
|||
import YourService from \"services/YourService.js\" |
|||
|
|||
class YourController extends BaseController { |
|||
constructor() { |
|||
super() // 必须调用 super() |
|||
this.yourService = new YourService() |
|||
} |
|||
|
|||
// 控制器方法 |
|||
async yourMethod(ctx) { |
|||
// 业务逻辑 |
|||
} |
|||
|
|||
// 路由定义 |
|||
static createRoutes() { |
|||
const controller = new YourController() |
|||
const router = new Router({ prefix: '/api/your-resource' }) |
|||
|
|||
router.get('/', controller.handleRequest(controller.yourMethod)) |
|||
|
|||
return router |
|||
} |
|||
} |
|||
``` |
|||
|
|||
### 2. 使用异常处理装饰器 |
|||
|
|||
**推荐方式**：使用 `handleRequest` 包装控制器方法，自动处理异常： |
|||
|
|||
```javascript |
|||
// 路由注册时使用 handleRequest |
|||
router.get('/', controller.handleRequest(controller.yourMethod)) |
|||
|
|||
// 控制器方法正常编写，无需 try-catch |
|||
async yourMethod(ctx) { |
|||
const data = await this.yourService.getData() |
|||
return this.success(ctx, data, \"获取数据成功\") |
|||
} |
|||
``` |
|||
|
|||
**手动方式**：如果需要自定义异常处理： |
|||
|
|||
```javascript |
|||
async yourMethod(ctx) { |
|||
try { |
|||
const data = await this.yourService.getData() |
|||
return this.success(ctx, data, \"获取数据成功\") |
|||
} catch (error) { |
|||
if (error instanceof CommonError) { |
|||
return this.error(ctx, error.message, null, 400) |
|||
} |
|||
return this.error(ctx, \"系统内部错误\", null, 500) |
|||
} |
|||
} |
|||
``` |
|||
|
|||
## 核心方法详解 |
|||
|
|||
### 响应方法 |
|||
|
|||
#### `success(ctx, data, message, statusCode)` |
|||
生成成功响应 |
|||
```javascript |
|||
return this.success(ctx, { id: 1, name: 'test' }, \"操作成功\", 200) |
|||
// 响应: { success: true, data: {...}, error: \"操作成功\" } |
|||
``` |
|||
|
|||
#### `error(ctx, message, data, statusCode)` |
|||
生成错误响应 |
|||
```javascript |
|||
return this.error(ctx, \"数据不存在\", null, 404) |
|||
// 响应: { success: false, data: null, error: \"数据不存在\" } |
|||
``` |
|||
|
|||
#### `paginated(ctx, paginationResult, message)` |
|||
生成分页响应 |
|||
```javascript |
|||
const result = await this.service.getDataWithPagination(page, limit) |
|||
return this.paginated(ctx, result, \"获取列表成功\") |
|||
// 响应: { success: true, data: { list: [...], pagination: {...} } } |
|||
``` |
|||
|
|||
### 参数处理 |
|||
|
|||
#### `validateParams(ctx, rules)` |
|||
验证请求参数（支持 body、query、params） |
|||
|
|||
```javascript |
|||
const data = this.validateParams(ctx, { |
|||
title: { |
|||
required: true, |
|||
minLength: 1, |
|||
maxLength: 100, |
|||
label: '标题' |
|||
}, |
|||
email: { |
|||
required: false, |
|||
type: 'email', |
|||
label: '邮箱' |
|||
}, |
|||
age: { |
|||
required: true, |
|||
type: 'number', |
|||
label: '年龄' |
|||
} |
|||
}) |
|||
``` |
|||
|
|||
**验证规则说明**： |
|||
- `required`: 是否必填 |
|||
- `type`: 数据类型（'number', 'email'） |
|||
- `minLength`/`maxLength`: 字符串长度限制 |
|||
- `label`: 字段显示名称（用于错误消息） |
|||
|
|||
#### `getPaginationParams(ctx, defaults)` |
|||
获取分页参数 |
|||
```javascript |
|||
const params = this.getPaginationParams(ctx, { |
|||
page: 1, |
|||
limit: 20, |
|||
orderBy: 'created_at', |
|||
order: 'desc' |
|||
}) |
|||
// 返回: { page: 1, limit: 20, orderBy: 'created_at', order: 'desc' } |
|||
``` |
|||
|
|||
#### `getSearchParams(ctx)` |
|||
获取搜索参数 |
|||
```javascript |
|||
const params = this.getSearchParams(ctx) |
|||
// 从 query 中提取: keyword, status, category, author |
|||
``` |
|||
|
|||
### 权限控制 |
|||
|
|||
#### `getCurrentUser(ctx)` |
|||
获取当前登录用户 |
|||
```javascript |
|||
const user = this.getCurrentUser(ctx) |
|||
if (!user) { |
|||
throw new CommonError(\"用户未登录\") |
|||
} |
|||
``` |
|||
|
|||
#### `checkPermission(ctx, permission)` |
|||
检查用户权限（需要根据业务实现权限逻辑） |
|||
```javascript |
|||
this.checkPermission(ctx, 'article.create') |
|||
``` |
|||
|
|||
#### `checkOwnership(ctx, resource, ownerField)` |
|||
检查资源所有权 |
|||
```javascript |
|||
const article = await this.articleService.getById(id) |
|||
this.checkOwnership(ctx, article, 'author') // 检查 article.author 是否为当前用户 |
|||
``` |
|||
|
|||
### 视图和文件处理 |
|||
|
|||
#### `render(ctx, template, data, options)` |
|||
渲染视图模板 |
|||
```javascript |
|||
return this.render(ctx, 'articles/detail', { |
|||
article, |
|||
title: article.title |
|||
}, { |
|||
includeSite: true, |
|||
includeUser: true |
|||
}) |
|||
``` |
|||
|
|||
#### `redirect(ctx, url, message)` |
|||
页面重定向 |
|||
```javascript |
|||
this.redirect(ctx, '/articles', '文章创建成功') |
|||
``` |
|||
|
|||
#### `getUploadedFile(ctx, fieldName)` |
|||
处理文件上传 |
|||
```javascript |
|||
const file = this.getUploadedFile(ctx, 'avatar') |
|||
if (file) { |
|||
console.log('文件名:', file.name) |
|||
console.log('文件大小:', file.size) |
|||
console.log('文件类型:', file.type) |
|||
console.log('文件路径:', file.path) |
|||
} |
|||
``` |
|||
|
|||

## 最佳实践 |
|||
|
|||
### 1. 统一错误处理 |
|||
- ✅ 使用 `handleRequest` 包装所有控制器方法 |
|||
- ✅ 业务异常抛出 `CommonError` |
|||
- ✅ 让 BaseController 自动处理系统异常 |
|||
|
|||
### 2. 参数验证 |
|||
- ✅ 总是验证用户输入 |
|||
- ✅ 使用有意义的字段标签 |
|||
- ✅ 根据业务需求设置合适的验证规则 |
|||
|
|||
### 3. 权限控制 |
|||
- ✅ 在需要的地方调用 `checkPermission` |
|||
- ✅ 对用户资源使用 `checkOwnership` |
|||
- ✅ 在路由级别设置基础权限要求 |
|||
|
|||
### 4. 响应格式 |
|||
- ✅ 使用统一的响应方法 |
|||
- ✅ 提供有意义的消息 |
|||
- ✅ 分页数据使用 `paginated` 方法 |
|||
|
|||
### 5. 代码组织 |
|||
- ✅ 保持控制器方法简洁 |
|||
- ✅ 业务逻辑放在 Service 层 |
|||
- ✅ 使用静态 `createRoutes` 方法定义路由 |
|||
|
|||
通过遵循这些模式，您可以创建一致、可维护且健壮的控制器代码。 |

# 配置抽离优化总结 |
|||
|
|||
## 🎯 优化目标 |
|||
|
|||
将路由性能监控中间件的硬编码配置抽离到通用配置系统中，实现配置的集中管理和环境变量支持。 |
|||
|
|||
## ✅ 完成的优化 |
|||
|
|||
### 1. 配置系统重构 |
|||
|
|||
**原来的问题**： |
|||
- 配置分散在各个组件中 |
|||
- 硬编码的配置值 |
|||
- 缺乏环境变量支持 |
|||
- 配置更新困难 |
|||
|
|||
**优化后的方案**： |
|||
- ✅ 集中配置管理 (`src/config/index.js`) |
|||
- ✅ 支持环境变量覆盖 |
|||
- ✅ 配置文件与环境变量双重支持 |
|||
- ✅ 运行时配置更新 |
|||
|
|||
### 2. 新增配置结构 |
|||
|
|||
```javascript |
|||
// src/config/index.js |
|||
export default { |
|||
routePerformance: { |
|||
// 基础配置 |
|||
enabled: process.env.NODE_ENV === 'production' || process.env.PERFORMANCE_MONITOR === 'true', |
|||
windowSize: parseInt(process.env.PERFORMANCE_WINDOW_SIZE) || 100, |
|||
slowRouteThreshold: parseInt(process.env.SLOW_ROUTE_THRESHOLD) || 500, |
|||
cleanupInterval: parseInt(process.env.PERFORMANCE_CLEANUP_INTERVAL) || 5 * 60 * 1000, |
|||
|
|||
// 高级配置 |
|||
dataRetentionTime: parseInt(process.env.PERFORMANCE_DATA_RETENTION) || 10 * 60 * 1000, |
|||
minAnalysisDataCount: parseInt(process.env.MIN_ANALYSIS_DATA_COUNT) || 10, |
|||
cacheHitRateWarningThreshold: parseFloat(process.env.CACHE_HIT_RATE_WARNING) || 0.5, |
|||
enableOptimizationSuggestions: process.env.ENABLE_OPTIMIZATION_SUGGESTIONS !== 'false', |
|||
maxRouteReportCount: parseInt(process.env.MAX_ROUTE_REPORT_COUNT) || 50 |
|||
} |
|||
} |
|||
``` |
|||
|
|||

|||
PERFORMANCE_WINDOW_SIZE=100 |
|||
SLOW_ROUTE_THRESHOLD=500 |
|||
|
|||
# 高级配置 |
|||
PERFORMANCE_CLEANUP_INTERVAL=300000 |
|||
PERFORMANCE_DATA_RETENTION=600000 |
|||
MIN_ANALYSIS_DATA_COUNT=10 |
|||
CACHE_HIT_RATE_WARNING=0.5 |
|||
ENABLE_OPTIMIZATION_SUGGESTIONS=true |
|||
MAX_ROUTE_REPORT_COUNT=50 |
|||
``` |
|||
|
|||
## 🚀 功能增强 |
|||
|
|||
### 1. 智能优化建议 |
|||
|
|||
新增了 `generateOptimizationSuggestions` 方法： |
|||
|
|||
```javascript |
|||
generateOptimizationSuggestions(routeKey, avgDuration, cacheHitRate) { |
|||
const suggestions = [] |
|||
|
|||
if (cacheHitRate < 0.3) { |
|||
suggestions.push('考虑增加路由缓存策略') |
|||
} |
|||
|
|||
if (avgDuration > this.config.slowRouteThreshold * 2) { |
|||
suggestions.push('考虑优化数据库查询或业务逻辑') |
|||
} |
|||
|
|||
if (cacheHitRate < 0.5 && avgDuration > this.config.slowRouteThreshold) { |
|||
suggestions.push('建议启用或优化响应缓存') |
|||
} |
|||
|
|||
if (suggestions.length > 0) { |
|||
logger.info(`[性能监控] ${routeKey} 优化建议: ${suggestions.join('; ')}`) |
|||
} |
|||
} |
|||
``` |
|||
|
|||

const oldEnabled = this.config.enabled |
|||
|
|||
// 合并配置 |
|||
this.config = { ...this.config, ...newConfig } |
|||
|
|||
// 如果启用状态发生变化，重新初始化 |
|||
if (oldEnabled !== this.config.enabled) { |
|||
if (this.config.enabled) { |
|||
this.startPeriodicCleanup() |
|||
} else { |
|||
this.performanceStats.clear() |
|||
} |
|||
} |
|||
} |
|||
``` |
|||
|

|||
|
|||
路由缓存已自动集成到路由系统中，无需额外配置： |
|||
|
|||
```javascript |
|||
// 控制器示例 |
|||
export default class UserController extends BaseController { |
|||
async getUser(ctx) { |
|||
// 第一次访问会进行路由匹配并缓存 |
|||
// 后续相同路径的请求将直接使用缓存 |
|||
return this.success(ctx, user) |
|||
} |
|||
|
|||
static createRoutes() { |
|||
const controller = new UserController() |
|||
const router = new Router({ prefix: '/api/users' }) |
|||
|
|||
router.get('/:id', controller.handleRequest(controller.getUser)) |
|||
return router |
|||
} |
|||
} |
|||
``` |
|||
|
|||
### 2. 手动缓存管理 |
|||
|
|||
```javascript |
|||
import routeCache from 'utils/cache/RouteCache.js' |
|||
|
|||
// 获取缓存统计 |
|||
const stats = routeCache.getStats() |
|||
console.log('缓存命中率:', stats.hitRate) |
|||
|
|||
// 清除特定文件的缓存 |
|||
routeCache.clearByFile('/path/to/controller.js') |
|||
|
|||
// 禁用缓存（开发调试） |
|||
routeCache.disable() |
|||
``` |
|||
|
|||
### 3. 性能监控 |
|||
|
|||
```javascript |
|||
import performanceMonitor from 'middlewares/RoutePerformance/index.js' |
|||
|
|||
// 获取性能报告 |
|||
const report = performanceMonitor.getPerformanceReport() |
|||
console.log('慢路由:', report.routes.filter(r => r.isSlowRoute)) |
|||
|
|||
// 获取慢路由列表 |
|||
const slowRoutes = performanceMonitor.getSlowRoutes() |
|||
``` |
|||
|
|||
## 性能优化建议 |
|||
|
|||
### 1. 生产环境配置 |
|||
|
|||
```javascript |
|||
// 生产环境建议配置 |
|||
{ |
|||
routeCache: { |
|||
enabled: true, |
|||
maxMatchCacheSize: 2000, // 增加缓存大小 |
|||
maxControllerCacheSize: 200, |
|||
maxMiddlewareCacheSize: 500, |
|||
performance: { |
|||
enabled: true, |
|||
slowRouteThreshold: 300 // 降低慢路由阈值 |
|||
} |
|||
} |
|||
} |
|||
``` |
|||
|
|||
### 2. 开发环境配置 |
|||
|
|||
```javascript |
|||
// 开发环境建议配置 |
|||
{ |
|||
routeCache: { |
|||
enabled: false, // 禁用缓存以便调试 |
|||
performance: { |
|||
enabled: true, // 保持性能监控 |
|||
slowRouteThreshold: 1000 |
|||
} |
|||
} |
|||
} |
|||
``` |
|||
|
|||
### 3. 缓存预热 |
|||
|
|||
```javascript |
|||
// 应用启动时预热常用路由 |
|||
const commonRoutes = [ |
|||
{ method: 'GET', path: '/api/users' }, |
|||
{ method: 'GET', path: '/api/articles' } |
|||
] |
|||
|
|||
commonRoutes.forEach(route => { |
|||
// 模拟请求以预热缓存 |
|||
// 实际实现可以在应用启动时发送内部请求 |
|||
}) |
|||
``` |
|||
|
|||
## 监控和调试 |
|||
|
|||
### 1. 日志输出 |
|||
|
|||
``` |
|||
[路由缓存] 初始化完成，缓存状态: 启用 |
|||
[路由注册] ✅ CommonController.js - 路由创建成功，已缓存 |
|||
[路由缓存] 缓存状态: 启用, 总命中率: 87.3% |
|||
[性能监控] 发现慢路由: GET:/api/complex-query, 平均响应时间: 832.15ms, 缓存命中率: 23.5% |
|||
``` |
|||
|
|||
### 2. 健康检查 |
|||
|
|||
系统会自动检查： |
|||
- 缓存命中率是否过低 |
|||
- 缓存大小是否过大 |
|||
- 是否存在性能问题 |
|||
|
|||
### 3. 告警和优化建议 |
|||
|
|||
当检测到问题时，系统会提供优化建议： |
|||
- 调整缓存策略 |
|||
- 增加缓存大小 |
|||
- 优化慢路由逻辑 |
|||
|
|||
## 注意事项 |
|||
|
|||
1. **内存使用**: 缓存会占用内存，需要根据服务器资源调整缓存大小 |
|||
2. **开发调试**: 开发环境建议禁用缓存以避免代码更改不生效 |
|||
3. **集群部署**: 当前是内存缓存，集群部署时每个实例独立缓存 |
|||
4. **缓存失效**: 文件变更会自动失效相关缓存，但手动修改需要重启应用 |
|||
|
|||
## 扩展功能 |
|||
|
|||
### 1. Redis 缓存适配 |
|||
|
|||
```javascript |
|||
// 未来可以扩展为 Redis 缓存 |
|||
class RedisRouteCache extends RouteCache { |
|||
// 实现 Redis 存储逻辑 |
|||
} |
|||
``` |
|||
|
|||
### 2. 分布式缓存 |
|||
|
|||
```javascript |
|||
// 支持集群间缓存同步 |
|||
class DistributedRouteCache extends RouteCache { |
|||
// 实现分布式缓存逻辑 |
|||
} |
|||
``` |
|||
|
|||
### 3. 更多性能指标 |
|||
|
|||
- 内存使用监控 |
|||
- 缓存空间利用率 |
|||
- 自动缓存优化算法 |

|
|||
// 搜索书签 |
|||
const searchResults = await bookmarkService.searchUserBookmarks(1, 'Google') |
|||
``` |
|||
|
|||
### 4. SiteConfigService - 站点配置服务 |
|||
管理站点的各种配置信息，如站点名称、描述、主题等。 |
|||
|
|||
**主要功能：** |
|||
- 配置的增删改查 |
|||
- 配置值验证 |
|||
- 批量操作支持 |
|||
- 默认配置初始化 |
|||
- 配置统计和搜索 |
|||
|
|||
**使用示例：** |
|||
```javascript |
|||
import { siteConfigService } from '../services/index.js' |
|||
|
|||
// 获取配置 |
|||
const siteName = await siteConfigService.get('site_name') |
|||
|
|||
// 设置配置 |
|||
await siteConfigService.set('site_name', '我的新网站') |
|||
|
|||
// 批量设置配置 |
|||
await siteConfigService.setMany({ |
|||
'site_description': '网站描述', |
|||
'posts_per_page': 20 |
|||
}) |
|||
|
|||
// 初始化默认配置 |
|||
await siteConfigService.initializeDefaultConfigs() |
|||
``` |
|||
|
|||
### 5. JobService - 任务服务 |
|||
处理后台任务和定时任务的管理。 |
|||
|
|||
**主要功能：** |
|||
- 任务调度和管理 |
|||
- 任务状态监控 |
|||
- 任务日志记录 |
|||
|
|||
## 错误处理 |
|||
|
|||
所有服务都使用统一的错误处理机制： |
|||
|
|||
```javascript |
|||
import CommonError from 'utils/error/CommonError.js' |
|||
|
|||
try { |
|||
const result = await userService.getUserById(1) |
|||
} catch (error) { |
|||
if (error instanceof CommonError) { |
|||
// 业务逻辑错误 |
|||
console.error(error.message) |
|||
} else { |
|||
// 系统错误 |
|||
console.error('系统错误:', error.message) |
|||
} |
|||
} |
|||
``` |
|||
|
|||
## 数据验证 |
|||
|
|||
服务层负责数据验证，确保数据的完整性和正确性： |
|||
|
|||
- **输入验证**：检查必填字段、格式验证等 |
|||
- **业务验证**：检查业务规则，如用户名唯一性 |
|||
- **权限验证**：确保用户只能操作自己的数据 |
|||
|
|||
## 事务支持 |
|||
|
|||
对于涉及多个数据库操作的方法，服务层支持事务处理： |
|||
|
|||
```javascript |
|||
// 在需要事务的方法中使用 |
|||
async createUserWithProfile(userData, profileData) { |
|||
// 这里可以添加事务支持 |
|||
const user = await this.createUser(userData) |
|||
// 创建用户档案... |
|||
return user |
|||
} |
|||
``` |
|||
|
|||
## 缓存策略 |
|||
|
|||
服务层可以集成缓存机制来提高性能： |
|||
|
|||
```javascript |
|||
// 示例：缓存用户信息 |
|||
async getUserById(id) { |
|||
const cacheKey = `user:${id}` |
|||
let user = await cache.get(cacheKey) |
|||
|
|||
if (!user) { |
|||
user = await UserModel.findById(id) |
|||
await cache.set(cacheKey, user, 3600) // 缓存1小时 |
|||
} |
|||
|
|||
return user |
|||
} |
|||
``` |
|||
|
|||
## 使用建议 |
|||
|
|||
1. **控制器层调用服务**：控制器应该调用服务层方法，而不是直接操作模型 |
|||
2. **错误处理**：在控制器中捕获服务层抛出的错误并返回适当的HTTP响应 |
|||
3. **数据转换**：服务层负责数据格式转换，控制器负责HTTP响应格式 |
|||
4. **业务逻辑**：复杂的业务逻辑应该放在服务层，保持控制器的简洁性 |
|||
|
|||
## 扩展指南 |
|||
|
|||
添加新的服务： |
|||
|
|||
1. 创建新的服务文件（如 `NewService.js`） |
|||
2. 继承或实现基础服务接口 |
|||
3. 在 `index.js` 中导出新服务 |
|||
4. 添加相应的测试用例 |
|||
5. 更新文档 |
|||
|
|||
```javascript |
|||
// 新服务示例 |
|||
class NewService { |
|||
async doSomething(data) { |
|||
try { |
|||
// 业务逻辑 |
|||
return result |
|||
} catch (error) { |
|||
throw new CommonError(`操作失败: ${error.message}`) |
|||
} |
|||
} |
|||
} |
|||
``` |
