# 服务器重启数据加载修复说明
|
||||
|
||||
## 问题描述
|
||||
|
||||
服务器重启后没有正确载入底层数据库中的数据，导致内存存储为空。
|
||||
|
||||
## 根本原因
|
||||
|
||||
在之前的实现中，服务器启动时只创建了空的 `MemoryStore`，但没有从数据库中加载已有的数据到内存中。这导致：
|
||||
|
||||
1. 服务器重启后，内存中的数据丢失
|
||||
2. 查询操作无法找到已有数据
|
||||
3. 插入操作可能产生重复数据
|
||||
|
||||
## 修复方案
|
||||
|
||||
### 1. 添加 `ListCollections` 方法到数据库适配器
|
||||
|
||||
为所有数据库适配器实现了 `ListCollections` 方法，用于获取数据库中所有现有的表（集合）：
|
||||
|
||||
**文件修改：**
|
||||
- `internal/database/base.go` - 添加基础方法声明
|
||||
- `internal/database/sqlite/adapter.go` - SQLite 实现
|
||||
- `internal/database/postgres/adapter.go` - PostgreSQL 实现
|
||||
- `internal/database/dm8/adapter.go` - DM8 实现
|
||||
|
||||
**SQLite 示例代码：**
|
||||
```go
|
||||
// ListCollections 获取所有集合（表）列表
|
||||
func (a *SQLiteAdapter) ListCollections(ctx context.Context) ([]string, error) {
|
||||
query := `SELECT name FROM sqlite_master WHERE type='table' AND name NOT LIKE 'sqlite_%' ORDER BY name`
|
||||
rows, err := a.GetDB().QueryContext(ctx, query)
|
||||
if err != nil {
|
||||
return nil, err
|
||||
}
|
||||
defer rows.Close()
|
||||
|
||||
var tables []string
|
||||
for rows.Next() {
|
||||
var table string
|
||||
if err := rows.Scan(&table); err != nil {
|
||||
return nil, err
|
||||
}
|
||||
tables = append(tables, table)
|
||||
}
|
||||
|
||||
return tables, rows.Err()
|
||||
}
|
||||
```
|
||||
|
||||
### 2. 添加 `Initialize` 方法到 MemoryStore
|
||||
|
||||
在 `internal/engine/memory_store.go` 中添加了 `Initialize` 方法：
|
||||
|
||||
```go
|
||||
// Initialize 从数据库加载所有现有集合到内存
|
||||
func (ms *MemoryStore) Initialize(ctx context.Context) error {
|
||||
if ms.adapter == nil {
|
||||
log.Println("[INFO] No database adapter, skipping initialization")
|
||||
return nil
|
||||
}
|
||||
|
||||
// 获取所有现有集合
|
||||
tables, err := ms.adapter.ListCollections(ctx)
|
||||
if err != nil {
|
||||
// 如果 ListCollections 未实现，返回 nil（不加载）
|
||||
if err.Error() == "not implemented" {
|
||||
log.Println("[WARN] ListCollections not implemented, skipping initialization")
|
||||
return nil
|
||||
}
|
||||
return fmt.Errorf("failed to list collections: %w", err)
|
||||
}
|
||||
|
||||
log.Printf("[INFO] Found %d collections in database", len(tables))
|
||||
|
||||
// 逐个加载集合
|
||||
loadedCount := 0
|
||||
for _, tableName := range tables {
|
||||
// 从数据库加载所有文档
|
||||
docs, err := ms.adapter.FindAll(ctx, tableName)
|
||||
if err != nil {
|
||||
log.Printf("[WARN] Failed to load collection %s: %v", tableName, err)
|
||||
continue
|
||||
}
|
||||
|
||||
// 创建集合并加载文档
|
||||
ms.mu.Lock()
|
||||
coll := &Collection{
|
||||
name: tableName,
|
||||
documents: make(map[string]types.Document),
|
||||
}
|
||||
for _, doc := range docs {
|
||||
coll.documents[doc.ID] = doc
|
||||
}
|
||||
ms.collections[tableName] = coll
|
||||
ms.mu.Unlock()
|
||||
|
||||
loadedCount++
|
||||
log.Printf("[DEBUG] Loaded collection %s with %d documents", tableName, len(docs))
|
||||
}
|
||||
|
||||
log.Printf("[INFO] Successfully loaded %d collections from database", loadedCount)
|
||||
return nil
|
||||
}
|
||||
```
|
||||
|
||||
### 3. 在服务器启动时调用初始化
|
||||
|
||||
修改 `cmd/server/main.go`，在创建内存存储后立即调用初始化：
|
||||
|
||||
```go
|
||||
// 创建内存存储
|
||||
store := engine.NewMemoryStore(adapter)
|
||||
|
||||
// 从数据库加载现有数据到内存
|
||||
log.Println("[INFO] Initializing memory store from database...")
|
||||
if err := store.Initialize(ctx); err != nil {
|
||||
log.Printf("[WARN] Failed to initialize memory store: %v", err)
|
||||
// 不阻止启动，继续运行
|
||||
}
|
||||
|
||||
// 创建 CRUD 处理器
|
||||
crud := engine.NewCRUDHandler(store, adapter)
|
||||
```
|
||||
|
||||
## 工作流程
|
||||
|
||||
```
|
||||
服务器启动流程：
|
||||
1. 连接数据库
|
||||
↓
|
||||
2. 创建 MemoryStore
|
||||
↓
|
||||
3. 【新增】调用 Initialize() 从数据库加载数据
|
||||
↓
|
||||
4. 创建 CRUDHandler
|
||||
↓
|
||||
5. 启动 HTTP/TCP 服务器
|
||||
```
|
||||
|
||||
## 测试方法
|
||||
|
||||
### 快速测试（推荐）
|
||||
|
||||
```bash
|
||||
cd /home/kingecg/code/gomog
|
||||
./test_quick.sh
|
||||
```
|
||||
|
||||
**预期输出：**
|
||||
```
|
||||
✅ 成功！服务器重启后正确加载了数据库中的数据
|
||||
=== 测试结果：SUCCESS ===
|
||||
```
|
||||
|
||||
### 详细测试
|
||||
|
||||
```bash
|
||||
./test_reload_simple.sh
|
||||
```
|
||||
|
||||
### 手动测试
|
||||
|
||||
1. **启动服务器并插入数据**
|
||||
```bash
|
||||
./bin/gomog -config config.yaml
|
||||
|
||||
# 在另一个终端插入数据
|
||||
curl -X POST http://localhost:8080/api/v1/testdb/users/insert \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{"documents": [{"name": "Alice", "age": 30}]}'
|
||||
```
|
||||
|
||||
2. **验证数据已存入数据库**
|
||||
```bash
|
||||
sqlite3 gomog.db "SELECT * FROM users;"
|
||||
```
|
||||
|
||||
3. **停止并重启服务器**
|
||||
```bash
|
||||
# Ctrl+C 停止服务器
|
||||
./bin/gomog -config config.yaml
|
||||
```
|
||||
|
||||
4. **查询数据（验证是否加载）**
|
||||
```bash
|
||||
curl -X POST http://localhost:8080/api/v1/testdb/users/find \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{"filter": {}}'
|
||||
```
|
||||
|
||||
应该能看到之前插入的数据。
|
||||
|
||||
## 日志输出示例
|
||||
|
||||
成功的初始化日志：
|
||||
```
|
||||
2026/03/14 22:00:00 [INFO] Connected to sqlite database
|
||||
2026/03/14 22:00:00 [INFO] Initializing memory store from database...
|
||||
2026/03/14 22:00:00 [INFO] Found 1 collections in database
|
||||
2026/03/14 22:00:00 [DEBUG] Loaded collection users with 2 documents
|
||||
2026/03/14 22:00:00 [INFO] Successfully loaded 1 collections from database
|
||||
2026/03/14 22:00:00 Starting HTTP server on :8080
|
||||
2026/03/14 22:00:00 Gomog server started successfully
|
||||
```
|
||||
|
||||
## 关键技术细节
|
||||
|
||||
### 集合名称映射
|
||||
|
||||
由于 HTTP API 使用 `dbName.collection` 格式（如 `testdb.users`），而 SQLite 数据库中表名不带前缀（如 `users`），实现了智能名称映射：
|
||||
|
||||
**1. Initialize 方法加载数据**
|
||||
```go
|
||||
// 从数据库加载时使用纯表名（例如：users）
|
||||
ms.collections[tableName] = coll
|
||||
```
|
||||
|
||||
**2. GetCollection 方法支持两种查找方式**
|
||||
```go
|
||||
// 首先尝试完整名称（例如：testdb.users）
|
||||
coll, exists := ms.collections[name]
|
||||
if exists {
|
||||
return coll, nil
|
||||
}
|
||||
|
||||
// 如果找不到，尝试去掉数据库前缀（例如：users）
|
||||
if idx := strings.Index(name, "."); idx > 0 {
|
||||
tableName := name[idx+1:]
|
||||
coll, exists = ms.collections[tableName]
|
||||
if exists {
|
||||
return coll, nil
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
这样确保了：
|
||||
- 新插入的数据可以使用 `testdb.users` 格式
|
||||
- 重启后加载的数据也能通过 `testdb.users` 查询到
|
||||
- 向后兼容，不影响现有功能
|
||||
|
||||
## 容错处理
|
||||
|
||||
修复实现了多层容错机制：
|
||||
|
||||
1. **无数据库适配器**：如果未配置数据库，跳过初始化
|
||||
2. **ListCollections 未实现**：如果数据库不支持列出表，记录警告但不阻止启动
|
||||
3. **单个集合加载失败**：记录错误但继续加载其他集合
|
||||
4. **初始化失败**：记录错误但服务器继续运行（不会崩溃）
|
||||
|
||||
## 影响范围
|
||||
|
||||
- ✅ 服务器重启后数据自动恢复
|
||||
- ✅ HTTP API 和 TCP 协议行为一致
|
||||
- ✅ 支持 SQLite、PostgreSQL、DM8 三种数据库
|
||||
- ✅ 向后兼容，不影响现有功能
|
||||
- ✅ 优雅降级，初始化失败不影响服务器启动
|
||||
|
||||

# 服务器重启数据加载功能 - 完成总结
|
||||
|
||||
## ✅ 问题解决
|
||||
|
||||
**原始问题**：服务器重启后没有正确载入底层数据库中的数据
|
||||
|
||||
**根本原因**：
|
||||
1. 服务器启动时只创建了空的 MemoryStore
|
||||
2. 没有从数据库加载已有数据到内存
|
||||
3. 集合名称不匹配（HTTP API 使用 `dbName.collection`，数据库表名不带前缀）
|
||||
|
||||
## 🎯 实现方案
|
||||
|
||||
### 1. 数据库适配器层
|
||||
|
||||
为所有数据库实现了 `ListCollections` 方法：
|
||||
|
||||
| 数据库 | 实现文件 | 查询方式 |
|
||||
|--------|---------|---------|
|
||||
| SQLite | `internal/database/sqlite/adapter.go` | `sqlite_master` 系统表 |
|
||||
| PostgreSQL | `internal/database/postgres/adapter.go` | `information_schema.tables` |
|
||||
| DM8 | `internal/database/dm8/adapter.go` | `USER_TABLES` 视图 |
|
||||
|
||||
### 2. 引擎层
|
||||
|
||||
在 `MemoryStore` 中添加：
|
||||
|
||||
- **`Initialize(ctx)` 方法**：启动时从数据库加载所有集合
|
||||
- **增强的 `GetCollection(name)` 方法**：支持两种名称格式的智能映射
|
||||
|
||||
### 3. 应用层
|
||||
|
||||
修改 `cmd/server/main.go`：
|
||||
```go
|
||||
store := engine.NewMemoryStore(adapter)
|
||||
if err := store.Initialize(ctx); err != nil {
|
||||
log.Printf("[WARN] Failed to initialize: %v", err)
|
||||
}
|
||||
```
|
||||
|
||||
## 🔧 技术亮点
|
||||
|
||||
### 集合名称智能映射
|
||||
|
||||
解决了关键的技术挑战：
|
||||
- HTTP API 使用：`testdb.users`
|
||||
- SQLite 表名：`users`
|
||||
- 实现透明映射，用户无感知
|
||||
|
||||
```go
|
||||
// GetCollection 支持两种查找方式
|
||||
func (ms *MemoryStore) GetCollection(name string) (*Collection, error) {
|
||||
// 1. 先查完整名称
|
||||
coll, exists := ms.collections[name]
|
||||
if exists {
|
||||
return coll, nil
|
||||
}
|
||||
|
||||
// 2. 再查纯表名（去掉 dbName. 前缀）
|
||||
if idx := strings.Index(name, "."); idx > 0 {
|
||||
tableName := name[idx+1:]
|
||||
coll, exists = ms.collections[tableName]
|
||||
if exists {
|
||||
return coll, nil
|
||||
}
|
||||
}
|
||||
|
||||
return nil, errors.ErrCollectionNotFnd
|
||||
}
|
||||
```
|
||||
|
||||
## 📊 测试结果

|
||||
|
||||
## 🔮 未来优化方向
|
||||
|
||||
1. **增量加载**：分页加载大数据集
|
||||
2. **懒加载**：首次访问时才加载
