+# Mapper 和 Service 层通用方法重构方案
+
+## 一、问题分析
+
+### 1.1 当前现状
+
+通过代码分析发现，项目中 Mapper 和 Service 层存在大量重复的通用 CRUD 方法实现：
+
+| 层级 | 重复率 | 具体数据 |
+|------|--------|----------|
+| Mapper | 80%+ | 8 个 Mapper 中，7 个实现了相同的通用方法 |
+| Service | 80%+ | 9 个 Service 中，8 个实现了相同的通用方法 |
+
+### 1.2 重复方法清单
+
+#### Mapper 层（10 个通用方法）
+- `FindAll(page, size int)` - 分页查询
+- `FindByID(id string)` - 根据 ID 查询
+- `Create(item *T)` - 创建单个记录
+- `Update(item *T)` - 更新单个记录
+- `UpdateFields(id string, fields map[string]interface{})` - 更新指定字段
+- `Delete(id string)` - 删除记录
+- `BatchCreate(items []T, batchSize int)` - 批量创建
+- `BatchUpdate(items []T)` - 批量更新
+- `BatchUpsert(items []T, updateColumns []string)` - 批量插入或更新
+- `BatchDelete(ids []string)` - 批量删除
+
+#### Service 层（10 个通用方法）
+- `List(page, size int)` - 分页查询（包装 Mapper.FindAll）
+- `GetByID(id string)` - 根据 ID 获取（包装 Mapper.FindByID）
+- `Create(item *T)` - 创建（包装 Mapper.Create + ID 生成）
+- `Update(item *T)` - 更新（包装 Mapper.Update）
+- `UpdateFields(id string, fields map[string]interface{})` - 更新指定字段
+- `Delete(id string)` - 删除（包装 Mapper.Delete）
+- `BatchCreate(items []T)` - 批量创建（包装 Mapper.BatchCreate + ID 生成）
+- `BatchUpdate(items []T)` - 批量更新（包装 Mapper.BatchUpdate）
+- `BatchUpsert(items []T, updateColumns []string)` - 批量插入或更新
+- `BatchDelete(ids []string)` - 批量删除（包装 Mapper.BatchDelete）
+
+### 1.3 存在的问题
+
+1. **代码重复率高**：超过 80% 的方法在所有 Mapper 和 Service 中重复实现
+2. **维护成本高**：修改通用逻辑需要在 8 个 Mapper 和 9 个 Service 中同步修改
+3. **不一致性风险**：不同开发者可能对相同方法实现略有差异
+4. **测试成本高**：需要对每个 Mapper 和 Service 的通用方法单独编写测试用例
+
+## 二、解决方案设计
+
+### 2.1 技术选型
+
+#### 方案对比
+
+| 方案 | 优点 | 缺点 | 适用场景 |
+|------|------|------|----------|
+| **泛型基类（推荐）** | 类型安全、零运行时开销、符合 Go 风格 | 需要 Go 1.18+ | ✅ 当前项目 |
+| 接口 + 组合 | 灵活、支持多种实现 | 需要手动实现所有方法 | 需要多态的场景 |
+| 代码生成 | 完全定制、性能最优 | 需要额外工具、学习成本高 | 大型项目 |
+
+**选择理由**：
+- 项目已使用 Go 1.21+，支持泛型
+- 泛型基类提供编译时类型检查，类型安全
+- 零运行时开销，性能最优
+- 代码简洁易读，符合 Go 语言惯例

+
+#### 泛型基类设计
+
+```go
+// BaseMapper 泛型 Mapper 基类
+type BaseMapper[T any] struct {
+    db *gorm.DB
+}
+
+// BaseService 泛型 Service 基类
+type BaseService[T any] struct {
+    mapper *BaseMapper[T]
+}
+```
+
+### 2.3 实现方案
+
+#### 2.3.1 BaseMapper 实现
+
+```go
+package common
+

+const DefaultBatchSize = 100
+
+// BaseMapper 泛型 Mapper 基类，封装通用 CRUD 操作
+type BaseMapper[T any] struct {
+    db *gorm.DB
+}
+
+// NewBaseMapper 创建 BaseMapper 实例
+func NewBaseMapper[T any]() *BaseMapper[T] {
+    return &BaseMapper[T]{
+        db: config.DB,
+    }
+}
+
+// GetDB 获取数据库实例（允许子类覆盖）
+func (m *BaseMapper[T]) GetDB() *gorm.DB {
+    return m.db
+}
+
+// FindAll 分页查询
+func (m *BaseMapper[T]) FindAll(page, size int) ([]T, int64, error) {

+
+#### 2.3.2 BaseService 实现
+
+```go

+
+// GetByID 根据 ID 获取

+    }
+    return nil
+}
+```
+
+### 2.4 使用示例
+
+#### 示例 1：普通 Mapper/Service（最简单）
+
+```go
+// mapper/yx_volunteer_mapper.go
+package mapper
+
+import (
+    "server/common"
+    "server/modules/yx/entity"
+)
+
+type YxVolunteerMapper struct {
+    *common.BaseMapper[entity.YxVolunteer]
+}
+
+func NewYxVolunteerMapper() *YxVolunteerMapper {
+    return &YxVolunteerMapper{
+        BaseMapper: common.NewBaseMapper[entity.YxVolunteer](),
+    }
+}
+
+// 只需要定义特殊方法，通用方法自动继承
+func (m *YxVolunteerMapper) FindActiveByScoreId(scoreId string) (*entity.YxVolunteer, error) {
+    var item entity.YxVolunteer
+    err := m.GetDB().Where("score_id = ? AND state = ?", scoreId, "1").First(&item).Error
+    return &item, err
+}
+
+func (m *YxVolunteerMapper) ListByUser(userID string, page, size int) ([]vo.UserVolunteerVO, int64, error) {
+    // 特殊查询逻辑
+    // ...
+}
+
+// service/yx_volunteer_service.go
+package service
+
+import (
+    "server/common"
+    "server/modules/yx/entity"
+    "server/modules/yx/mapper"
+)
+
+type YxVolunteerService struct {
+    *common.BaseService[entity.YxVolunteer]
+    mapper *mapper.YxVolunteerMapper
+}
+
+func NewYxVolunteerService() *YxVolunteerService {
+    mapper := mapper.NewYxVolunteerMapper()
+    return &YxVolunteerService{
+        BaseService: common.NewBaseService[entity.YxVolunteer](),
+        mapper:      mapper,
+    }
+}
+
+// 只需要定义特殊方法，通用方法自动继承
+func (s *YxVolunteerService) CreateByScoreId(scoreId string, userId string) error {
+    // 特殊业务逻辑
+    // ...
+}
+
+func (s *YxVolunteerService) SwitchVolunteer(id, userID string) error {
+    // 特殊业务逻辑
+    // ...
+}
+```
+
+#### 示例 2：需要逻辑删除的 Mapper
+
+```go
+// mapper/sys_user_mapper.go
+package mapper
+
+import (
+    "server/common"
+    "server/modules/system/entity"
+    "gorm.io/gorm"
+)
+
+type SysUserMapper struct {
+    *common.BaseMapper[entity.SysUser]
+}
+
+func NewSysUserMapper() *SysUserMapper {
+    return &SysUserMapper{
+        BaseMapper: common.NewBaseMapper[entity.SysUser](),
+    }
+}
+
+// 覆盖 GetDB 方法，添加逻辑删除过滤
+func (m *SysUserMapper) GetDB() *gorm.DB {
+    return m.BaseMapper.GetDB().Where("del_flag = 0")
+}
+
+// 覆盖 Delete 方法，使用逻辑删除
+func (m *SysUserMapper) Delete(id string) error {
+    return m.BaseMapper.GetDB().Model(new(entity.SysUser)).Where("id = ?", id).Update("del_flag", 1).Error
+}
+```
+
+#### 示例 3：需要自定义 Create 逻辑的 Service
+
+```go
+// service/sys_user_service.go
+package service
+
+import (
+    "server/common"
+    "server/modules/system/entity"
+    "server/modules/system/mapper"
+)
+
+type SysUserService struct {
+    *common.BaseService[entity.SysUser]
+    mapper *mapper.SysUserMapper
+}
+
+func NewSysUserService() *SysUserService {
+    mapper := mapper.NewSysUserMapper()
+    return &SysUserService{
+        BaseService: common.NewBaseService[entity.SysUser](),
+        mapper:      mapper,
+    }
+}
+
+// 覆盖 Create 方法，添加密码加密逻辑
+func (s *SysUserService) Create(item *entity.SysUser) error {
+    item.ID = common.GenerateStringID()
+    item.Salt = uuid.New().String()[:8]
+
+    encrypted, err := common.Encrypt(item.Username, item.Password, item.Salt)
+    if err != nil {
+        return fmt.Errorf("密码加密失败: %w", err)
+    }
+    item.Password = encrypted
+    item.DelFlag = 0
+    item.Status = 1
+    now := time.Now()
+    item.CreateTime = &now
+
+    return s.mapper.Create(item)
+}
+```
+
+### 2.5 特殊化处理
+
+#### 支持的场景
+
+| 场景 | 处理方式 | 代码示例 |
+|------|----------|----------|
+| 逻辑删除 | 覆盖 GetDB() | 添加 `del_flag = 0` 过滤 |

+| 密码加密 | 覆盖 Create() | 添加加密逻辑 |
+| 自定义查询条件 | 覆盖 GetDB() | 添加额外 Where 条件 |
+| 动态表名 | 在 Mapper 中定义新方法 | 直接使用 Table() |
+| 自定义批量大小 | 调用时指定参数 | `BatchCreate(items, 50)` |

+## 四、迁移计划
+
+### 4.1 迁移步骤
+

+
+#### 阶段 2：逐步迁移（按模块迁移）
+
+| 优先级 | 模块 | 原因 |
+|--------|------|------|
+| P0 | yx_volunteer | 最简单，无特殊逻辑 |
+| P0 | yx_volunteer_record | 最简单，无特殊逻辑 |
+| P1 | yx_school_major | 简单，无特殊逻辑 |
+| P1 | yx_user_score | 简单，无特殊逻辑 |
+| P2 | yx_calculation_major | 有动态表名，需要特殊处理 |
+| P2 | yx_history_major_enroll | 简单 |
+| P3 | sys_user | 有逻辑删除和密码加密，需要覆盖方法 |
+
+#### 阶段 3：验证和测试
+
+1. 运行现有测试用例
+2. 验证所有 API 接口
+3. 性能测试对比
+
+#### 阶段 4：清理旧代码
+
+1. 删除重复的通用方法实现
+2. 更新代码注释
+3. 更新文档
+
+### 4.2 风险评估
+
+| 风险 | 等级 | 缓解措施 |
+|------|------|----------|
+| 泛型兼容性问题 | 低 | 项目已使用 Go 1.21+，支持泛型 |
+| 运行时行为变化 | 低 | 基类逻辑与现有实现一致 |
+| 测试覆盖不足 | 中 | 增加单元测试和集成测试 |
+| 特殊逻辑遗漏 | 中 | 逐个模块迁移，充分测试 |
+| 性能回归 | 低 | 泛型零运行时开销 |
+
