+--- + +## 2. 配置管理 + +### 2.1 配置文件结构 + +```yaml +# config.yaml +app: + name: "我的应用" + site_name: "my_app" # 站点别名（重要：多项目共用Redis时区分） + version: "1.0.0" + env: "dev" # dev/test/prod + debug: true +

3. 日志系统 + +### 3.1 初始化日志 + +```go +import "github.com/EthanCodeCraft/xlgo-core/logger" + +// 初始化 +logger.Init(cfg) + +// 程序退出前同步 +defer logger.Sync() +``` + +### 3.2 日志级别 + +```go +// 基础日志 +logger.Debug("调试信息") +logger.Info("普通信息") +logger.Warn("警告信息") +logger.Error("错误信息") + +// 格式化日志 +logger.Infof("用户 %s 登录成功", username) +logger.Warnf("请求失败: %v", err) + +// 致命错误（会终止程序） +logger.Fatalf("数据库连接失败: %v", err) + +// 结构化日志 +logger.Info("用户登录", + zap.String("username", "admin"), + zap.Int("user_id", 123), +) +``` + +### 3.3 彩色控制台输出 + +开发调试时使用彩色输出，一眼识别日志级别： + +```go +import

自定义配置 +c := console.New( + console.WithColor(true), + console.WithTime(true), + console.WithCaller(true, 2), +) +c.Debug("自定义输出") +``` + +--- + +## 4. 数据库操作 + +### 4.1 初始化数据库 + +```go +import "github.com/EthanCodeCraft/xlgo-core/database" + +// 初始化 MySQL +database.InitMySQL(cfg) + +// 关闭连接 +defer database.Close() + +// 获取数据库实例 +db := database.GetDB() +``` + +### 4.2 定义模型 + +```go +import "github.com/EthanCodeCraft/xlgo-core/model" + +type User struct { + model.BaseModel // 包含 ID, CreatedAt, UpdatedAt + Username string `gorm:"size:50;unique" json:"username"` + Email string `gorm:"size:100" json:"email"` + Password string `gorm:"size:255" json:"-"` + Status int `gorm:"default:1" json:"status"` +} + +func (User) TableName() string { + return "users" +} +``` + +### 4.3 使用 Repository（扩展版） + +```go +import "github.com/EthanCodeCraft/xlgo-core/repository" + +// 创建仓库 +userRepo := repository.NewBaseRepo[model.User](database.GetDB()) + +// 基础 CRUD +user, err := userRepo.FindByID(ctx, 1) +users, err := userRepo.FindAll(ctx) +users, err := userRepo.FindByIDs(ctx, []uint{1, 2, 3}) +err := userRepo.Create(ctx, &user) +err := userRepo.Update(ctx, &user) +err := userRepo.Delete(ctx, 1) + +// 统计数量 +count, err := userRepo.Count(ctx) +count, err := userRepo.CountWhere(ctx, "status = ?", 1) + +// 分页查询（内置） +result, err := userRepo.FindPage(ctx, 1, 20) +// result.Items - 数据列表 +// result.Total - 总数 +// result.Page - 当前页 +// result.PageSize - 每页数量 + +// 条件分页查询 +result, err := userRepo.FindPageWhere(ctx, 1, 20, "status = ?", 1) + +// 分页并排序 +result, err := userRepo.FindPageOrdered(ctx, 1, 20, "created_at DESC") + +// 条件查询 +user, err := userRepo.FindOne(ctx, "email = ?", "test@example.com") +users, err := userRepo.FindWhere(ctx, "status = ?", 1) +users, err := userRepo.FindWhereOrdered(ctx, "status = ?", 1, []any{}, "created_at DESC") + +// 排序查询 +users, err := userRepo.FindOrdered(ctx, "created_at DESC", 10) + +// 批量操作 +err := userRepo.CreateBatch(ctx, users) +err := userRepo.UpdateBatch(ctx, []uint{1, 2}, "status", 2) +err := userRepo.DeleteBatch(ctx, []uint{1, 2, 3}) + +// 存在性检查 +exists, err := userRepo.Exists(ctx, 1) +exists, err := userRepo.ExistsWhere(ctx, "email = ?", "test@example.com") + +// 软删除恢复 +err := userRepo.Restore(ctx, 1) +err := userRepo.RestoreBatch(ctx, []uint{1, 2}) + +// 查询已删除的记录 +deletedUsers, err := userRepo.FindDeleted(ctx) + +// 链式查询（灵活构建） +users, err := userRepo.NewQueryBuilder(). + Where("status = ?", 1). + Where("role = ?", "admin"). + Order("created_at DESC"). + Limit(10). + Find(ctx) + +// 链式分页查询 +result, err := userRepo.NewQueryBuilder(). + Where("status = ?", 1). + Order("created_at DESC"). + Page(ctx, 1, 20) + +// 事务支持 +err := userRepo.WithTransaction(ctx, func(txRepo *repository.BaseRepo[model.User]) error { + // 创建用户 + if err := txRepo.Create(ctx, &user); err != nil { + return err + } + // 更新关联数据 + return txRepo.Update(ctx, &profile) +}) +``` + +### 4.4 Model 基础模型 + +```go +import "github.com/EthanCodeCraft/xlgo-core/model" + +// BaseModel 包含 ID、CreatedAt、UpdatedAt、DeletedAt +type User struct { + model.BaseModel // 自动包含 ID、时间戳、软删除 + Username string `gorm:"size:50;unique" json:"username"` + Email string `gorm:"size:100" json:"email"` + Status int `gorm:"default:1" json:"status"` +} + +// BaseModel 字段说明 +// ID uint - 主键 +// CreatedAt time.Time - 创建时间 +// UpdatedAt time.Time - 更新时间 +// DeletedAt gorm.DeletedAt - 软删除时间（不返回给前端） +``` + +--- + +## 5. 缓存与 Redis + +### 5.1 初始化缓存 + +```go +import "github.com/EthanCodeCraft/xlgo-core/cache" + +// 初始化（通常在应用启动时） +cache.Init() + +// 获取缓存实例 +c := cache.GetCache() +``` + +### 5.2 缓存操作 + +```go +// 设置缓存 +c.Set(ctx, "user:1", userData, 30*time.Minute) + +// 获取缓存 +var user User +if c.Get(ctx, "user:1", &user) { + // 缓存命中 +} + +// 删除缓存 +c.Delete(ctx, "user:1") + +// 批量删除（按模式） +c.DeleteByPattern(ctx, "user:*") + +// 检查是否存在 +exists := c.Exists(ctx, "user:1") +``` + +### 5.3 键名前缀管理（多站点共用 Redis） + +```go +import "github.com/EthanCodeCraft/xlgo-core/cache" + +// 自动从配置读取 site_name 作为前缀 +// config.yaml: app.site_name: "my_app" + +cache.K("user:1") // → "cache:my_app:user:1" +cache.KTemp("token") // → "temp:my_app:token" +cache.KPerm("config") // → "perm:my_app:config" +cache.KLock("order:123") // → "lock:my_app:order:123" +cache.KCounter("visit") // → "counter:my_app:visit" +cache.KSession("sid") // → "session:my_app:sid" + +// 使用带前缀的缓存 +c.Set(ctx, cache.K("user:1"), userData, ttl) +c.Get(ctx, cache.K("user:1"), &user) +``` + +### 5.4 分布式锁（安全增强版） + +**使用 Lua 脚本 + UUID Token，只有锁的持有者才能释放锁：** + +```go +// 安全加锁（返回 LockToken） +token, err := cache.NewLock(ctx, cache.KLock("pay:123"), 30*time.Second) +if token != nil { + defer cache.Unlock(ctx, token) // 只有持有者能释放 + // 执行业务逻辑 +} + +// 带重试的锁 +token, err := cache.TryLock(ctx, key, ttl, 100*time.Millisecond, 10) +if token != nil { + defer cache.Unlock(ctx, token) +} + +// 自动管理锁（简单场景） +err := cache.WithLock(ctx, key, ttl, func() error { + return nil +}) + +// 自动续期锁（长任务场景） +err := cache.WithLockAutoExtend(ctx, key, 30*time.Second, 10*time.Second, func() error { + // 执行时间超过 TTL 时自动续期 + return nil +}) + +// 续期锁（手动续期） +cache.ExtendLock(ctx, token, 30*time.Second) + +// 检查锁是否被占用 +locked, err := cache.IsLocked(ctx, key) + +// 强制释放锁（管理场景） +cache.ForceUnlock(ctx, key) +``` + +**安全特性：** +- Lua 脚本保证原子性操作 +- UUID Token 标识锁的持有者 +- 只有持有者才能释放锁（防止误释放） +- 支持续期（长任务不会因锁过期而中断） + +### 5.5 计数器 + +```go +// 自增 +n, err := cache.Incr(ctx, cache.KCounter("page_view")) + +// 指定增量 +n, err := cache.IncrBy(ctx, key, 10) + +// 自减 +n, err := cache.Decr(ctx, key) + +// 设置过期时间 +cache.SetExpire(ctx, key, 1*time.Hour) + +// 获取剩余时间 +ttl, err := cache.GetTTL(ctx, key) +``` + +--- + +## 6. 请求处理 + +### 6.1 参数获取 + +```go +import "github.com/EthanCodeCraft/xlgo-core/handler" + +// 类型安全的参数获取（推荐） + +// Query参数 +page := handler.QueryInt(c, "page", 1) // Query参数 → int +id := handler.QueryInt64(c,

+enabled := handler.FormBool(c, "enabled", false) // 表单参数 → bool +name := handler.FormString(c, "name", "") // 表单参数 → string + +// 分页参数 +page, pageSize := handler.GetPage(c) // 默认 page=1, pageSize=20 + +// 路径ID +id, ok := handler.GetIDFromPath(c, "id") + +// 绑定请求 +var req LoginRequest +handler.BindJSON(c, &req) +``` + +### 6.2 请求验证 + +```go +import "github.com/EthanCodeCraft/xlgo-core/validation" + +type RegisterRequest struct { + Username string `json:"username" label:"用户名" validate:"required,min=3,max=20" msg_required:"用户名不能为空"` + Password string `json:"password" label:"密码"

validate:"omitempty,phone"` +} + +// 绑定并验证 +errors, ok := validation.ShouldBindAndValidate(c, &req) +if !ok { + response.Fail(c, errors.Error()) + return +} +``` + +### 6.3 验证规则 + +| 规则 | 说明 | +|
