|
||||
|
||||
## 🎯 核心概念理解
|
||||
|
||||
### 1️⃣ 什么是数据持久化？
|
||||
|
||||
**数据持久化** = 数据保存 + 长期存储
|
||||
|
||||
**生活中的比喻：**
|
||||
- 📱 微信聊天记录 - 关闭APP后重新打开，聊天记录还在
|
||||
- 📞 手机通讯录 - 重启手机后联系人信息不丢失
|
||||
- 🎮 游戏进度 - 退出游戏下次继续，进度保存着
|
||||
- 📚 我们的电子书库 - 退出Readful应用后，书籍信息还在
|
||||
|
||||
### 2️⃣ 为什么需要数据持久化？
|
||||
|
||||
**问题：** 如果没有数据持久化
|
||||
- 用户添加的书籍 → 关闭应用就丢失了 😱
|
||||
- 阅读进度 → 重新打开要从头开始 😭
|
||||
- 书签和高亮 → 全部消失 😰
|
||||
|
||||
**解决方案：** 数据持久化
|
||||
- ✅ 数据永久保存（除非用户删除）
|
||||
- ✅ 应用重启后数据依然存在
|
||||
- ✅ 用户体验持续和连贯
|
||||
|
||||
### 3️⃣ 为什么选择Hive数据库？
|
||||
|
||||
**Hive = 轻量级 + 快速 + 简单**
|
||||
|
||||
**🚀 优势对比：**
|
||||
|
||||
| 特性 | Hive | SQLite | SharedPreferences |
|
||||
|------|------|--------|-------------------|
|
||||
| **速度** | ⭐⭐⭐⭐⭐ | ⭐⭐⭐ | ⭐⭐⭐⭐ |
|
||||
| **易用性** | ⭐⭐⭐⭐⭐ | ⭐⭐ | ⭐⭐⭐ |
|
||||
| **对象支持** | ✅ 直接存储对象 | ❌ 需要SQL语句 | ❌ 只支持基本类型 |
|
||||
| **离线能力** | ✅ 完全离线 | ✅ 完全离线 | ✅ 完全离线 |
|
||||
| **类型安全** | ✅ 编译时检查 | ⚠️ 运行时错误 | ⚠️ 运行时错误 |

||||
|
||||
### 📦 Hive安装和配置
|
||||
|
||||
#### 1️⃣ 依赖配置
|
||||
```yaml
|
||||
# pubspec.yaml
|
||||
dependencies:
|
||||
hive: ^2.2.3 # Hive核心库
|
||||
hive_flutter: ^1.1.0 # Flutter集成
|
||||
path_provider: ^2.0.14 # 文件路径管理
|
||||
|
||||
dev_dependencies:
|
||||
hive_generator: ^2.0.0 # TypeAdapter生成器
|
||||
build_runner: ^2.4.6 # 代码生成工具
|
||||
```
|
||||
|
||||
#### 2️⃣ 安装依赖
|
||||
```bash
|
||||
flutter pub get
|
||||
```
|
||||
|
||||
### 🔧 Hive基础操作
|
||||
|
||||
#### 1️⃣ 数据库初始化
|
||||
```dart
|
||||
import 'package:hive_flutter/hive_flutter.dart';
|
||||
import 'package:path_provider/path_provider.dart';
|
||||
|
||||
Future<void> initHive() async {
|
||||
// 获取应用文档目录
|
||||
final appDocumentDir = await getApplicationDocumentsDirectory();
|
||||
|
||||
// 初始化Hive
|
||||
await Hive.initFlutter(appDocumentDir.path);
|
||||
|
||||
print('✅ Hive初始化完成');
|
||||
}
|
||||
```
|
||||
|
||||
#### 2️⃣ 打开和关闭Box
|
||||
```dart
|
||||
// 打开Box（数据容器）
|
||||
Box<String> settingsBox = await Hive.openBox<String>('settings');
|
||||
Box<Book> booksBox = await Hive.openBox<Book>('books');
|
||||
|
||||
// 检查Box是否打开
|
||||
bool isOpen = Hive.isBoxOpen('books');
|
||||
|
||||
// 获取已打开的Box
|
||||
Box<String> myBox = Hive.box('settings');
|
||||
|
||||
// 关闭单个Box
|
||||
await settingsBox.close();
|
||||
|
||||
// 关闭所有Box
|
||||
await Hive.close();
|
||||
```
|
||||
|
||||
#### 3️⃣ 基本CRUD操作
|
||||
```dart
|
||||
// 📝 CREATE - 添加数据
|
||||
await settingsBox.put('theme', 'dark');
|
||||
await settingsBox.put('fontSize', 16.0);
|
||||
|
||||
// 📖 READ - 读取数据
|
||||
String? theme = settingsBox.get('theme'); // 'dark'
|
||||
double fontSize = settingsBox.get('fontSize', defaultValue: 14.0); // 16.0
|
||||
|
||||
// 获取所有键值对
|
||||
Map<String, dynamic> allSettings = settingsBox.toMap();
|
||||
|
||||
// 获取所有值
|
||||
List<String> allValues = settingsBox.values.toList();
|
||||
|
||||
// 获取所有键
|
||||
List<String> allKeys = settingsBox.keys.toList();
|
||||
|
||||
// ✏️ UPDATE - 更新数据
|
||||
await settingsBox.put('theme', 'light'); // 更新已存在的键
|
||||
|
||||
// 🗑️ DELETE - 删除数据
|
||||
await settingsBox.delete('theme');
|
||||
await settingsBox.deleteAll(['theme', 'fontSize']);
|
||||
|
||||
// 清空整个Box
|
||||
await settingsBox.clear();
|
||||
```
|
||||
|
||||
### 🎯 Hive高级操作
|
||||
|
||||
#### 1️⃣ 条件查询
|
||||
```dart
|
||||
// 查询所有key以'user_'开头的项目
|
||||
Iterable<String> userKeys = settingsBox.keys.where((key) => key.startsWith('user_'));
|
||||
|
||||
// 查询所有值大于10的项目
|
||||
Iterable<double> largeValues = settingsBox.values.whereType<double>()
|
||||
.where((value) => value > 10);
|
||||
|
||||
// 查找特定条件的键值对
|
||||
Map<String, dynamic> filteredData = {};
|
||||
for (var entry in settingsBox.toMap().entries) {
|
||||
if (entry.key.toString().contains('important')) {
|
||||
filteredData[entry.key] = entry.value;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### 2️⃣ 数据监听
|
||||
```dart
|
||||
// 监听数据变化
|
||||
settingsBox.listenable().addListener(() {
|
||||
print('Settings box数据发生变化');
|
||||
// 在这里可以更新UI或执行其他操作
|
||||
});
|
||||
|
||||
// 监听特定键的变化
|
||||
settingsBox.watch(key: 'theme').listen((event) {
|
||||
print('主题设置改变: ${event.value}');
|
||||
// 可以在这里切换UI主题
|
||||
});
|
||||
```
|
||||
|
||||
#### 3️⃣ 批量操作
|
||||
```dart
|
||||
// 批量添加数据
|
||||
await settingsBox.putAll({
|
||||
'theme': 'dark',
|
||||
'fontSize': 16.0,
|
||||
'language': 'zh_CN',
|
||||
'autoSave': true,
|
||||
});
|
||||
|
||||
// 批量删除数据
|
||||
List<String> keysToDelete = ['temp1', 'temp2', 'temp3'];
|
||||
await settingsBox.deleteAll(keysToDelete);
|
||||
```
|
||||
|
||||
### 🔍 Hive数据类型支持
|
||||
|
||||
#### 1️⃣ 原生支持的数据类型
|
||||
```dart
|
||||
// ✅ 基本类型
|
||||
Box<String> stringBox = await Hive.openBox<String>('strings');
|
||||
Box<int> intBox = await Hive.openBox<int>('integers');
|
||||
Box<double> doubleBox = await Hive.openBox<double>('doubles');
|
||||
Box<bool> boolBox = await Hive.openBox<bool>('booleans');
|
||||
Box<DateTime> dateBox = await Hive.openBox<DateTime>('dates');
|
||||
Box<List<String>> listBox = await Hive.openBox<List<String>>('lists');
|
||||
Box<Map<String, dynamic>> mapBox = await Hive.openBox<Map<String, dynamic>>('maps');
|
||||
```
|
||||
|
||||
#### 2️⃣ 自定义类型（需要TypeAdapter）
|
||||
```dart
|
||||
// 自定义类
|
||||
@HiveType(typeId: 0)
|
||||
class Person {
|
||||
@HiveField(0) final String name;
|
||||
@HiveField(1) final int age;
|
||||
|
||||
const Person({required this.name, required this.age});
|
||||
}
|
||||
|
||||
// 注册TypeAdapter
|
||||
Hive.registerAdapter(PersonAdapter());
|
||||
|
||||
// 使用自定义类型
|
||||
Box<Person> personBox = await Hive.openBox<Person>('persons');
|
||||
|
||||
// 添加自定义对象
|
||||
await personBox.put('user1', Person(name: '张三', age: 25));
|
||||
|
||||
// 读取自定义对象
|
||||
Person? user = personBox.get('user1');
|
||||
```
|
||||
|
||||
### 📊 Hive性能优化
|
||||
|
||||
#### 1️⃣ 延迟初始化
|
||||
```dart
|
||||
class LazyBoxManager {
|
||||
Box<Book>? _booksBox;
|
||||
|
||||
Box<Book> get booksBox {
|
||||
_booksBox ??= Hive.box<Book>('books');
|
||||
return _booksBox!;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### 2️⃣ 事务操作
|
||||
```dart
|
||||
// 使用事务确保数据一致性
|
||||
await Hive.openBox<String>('settings');
|
||||
await settingsBox.putAll({
|
||||
'operation1': 'value1',
|
||||
'operation2': 'value2',
|
||||
});
|
||||
|
||||
// 如果出现错误，操作会自动回滚
|
||||
```
|
||||
|
||||
#### 3️⃣ 内存管理
|
||||
```dart
|
||||
// 及时关闭不再使用的Box
|
||||
await tempBox.close();
|
||||
|
||||
// 定期压缩数据库
|
||||
await Hive.compact();
|
||||
```
|
||||
|
||||
### 🚨 常见问题和解决方案
|
||||
|
||||
#### 1️⃣ "Cannot write, unknown type" 错误
|
||||
```dart
|
||||
// ❌ 错误：未注册TypeAdapter
|
||||
@HiveType(typeId: 0)
|
||||
class Book { ... }
|
||||
|
||||
await bookBox.put('book1', myBook); // 会报错
|
||||
|
||||
// ✅ 正确：注册TypeAdapter
|
||||
Hive.registerAdapter(BookAdapter());
|
||||
await bookBox.put('book1', myBook); // 正常工作
|
||||
```
|
||||
|
||||
#### 2️⃣ "Box is not open" 错误
|
||||
```dart
|
||||
// ❌ 错误：忘记打开Box
|
||||
Box<Book> booksBox = Hive.box<Book>('books'); // 如果Box未打开会报错
|
||||
|
||||
// ✅ 正确：先打开Box
|
||||
Box<Book> booksBox = await Hive.openBox<Book>('books');
|
||||
|
||||
// 或者使用惰性Box（会自动打开）
|
||||
LazyBox<Book> lazyBox = Hive.lazyBox<Book>('books');
|
||||
```
|
||||
|
||||
#### 3️⃣ 数据迁移
|
||||
```dart
|
||||
// 检查数据库版本
|
||||
const int currentVersion = 2;
|
||||
const int savedVersion = settingsBox.get('db_version', defaultValue: 0);
|
||||
|
||||
if (savedVersion < currentVersion) {
|
||||
// 执行数据迁移
|
||||
await migrateDatabase(savedVersion, currentVersion);
|
||||
settingsBox.put('db_version', currentVersion);
|
||||
}
|
||||
```
|
||||
|
||||
### 🔧 Hive开发工具
|
||||
|
||||
#### 1️⃣ 调试技巧
|
||||
```dart
|
||||
// 查看Box内容
|
||||
print('Box内容: ${settingsBox.toMap()}');
|
||||
|
||||
// 查看Box统计信息
|
||||
print('Box长度: ${settingsBox.length}');
|
||||
print('是否为空: ${settingsBox.isEmpty}');
|
||||
print('所有键: ${settingsBox.keys}');
|
||||
```
|
||||
|
||||
#### 2️⃣ 数据导出和导入
|
||||
```dart
|
||||
// 导出数据
|
||||
Map<String, dynamic> exportData = settingsBox.toMap();
|
||||
String jsonString = jsonEncode(exportData);
|
||||
|
||||
// 导入数据
|
||||
Map<String, dynamic> importData = jsonDecode(jsonString);
|
||||
await settingsBox.putAll(importData);
|
||||
```
|
||||
|
||||
### 🎯 最佳实践
|
||||
|
||||
#### 1️⃣ 数据库结构设计
|
||||
```dart
|
||||
// 使用有意义的Box名称
|
||||
Box<Book> booksBox = await Hive.openBox<Book>('books');
|
||||
Box<Bookmark> bookmarksBox = await Hive.openBox<Bookmark>('bookmarks');
|
||||
Box<String> settingsBox = await Hive.openBox<String>('app_settings');
|
||||
|
||||
// 使用一致的键命名规范
|
||||
await settingsBox.put('user_theme', 'dark');
|
||||
await settingsBox.put('user_font_size', 16);
|
||||
await settingsBox.put('user_language', 'zh_CN');
|
||||
```
|
||||
|
||||
#### 2️⃣ 错误处理
|
||||
```dart
|
||||
try {
|
||||
await bookBox.put('book1', myBook);
|
||||
} on HiveError catch (e) {
|
||||
print('Hive错误: $e');
|
||||
} catch (e) {
|
||||
print('未知错误: $e');
|
||||
}
|
||||
```
|
||||
|
||||
#### 3️⃣ 资源管理
|
||||
```dart
|
||||
class DatabaseService {
|
||||
static DatabaseService? _instance;
|
||||
static DatabaseService get instance => _instance ??= DatabaseService._();
|
||||
|
||||
DatabaseService._();
|
||||
|
||||
Future<void> init() async {
|
||||
await Hive.initFlutter();
|
||||
// 注册TypeAdapter
|
||||
// 打开Box
|
||||
}
|
||||
|
||||
Future<void> close() async {
|
||||
await Hive.close();
|
||||
}
|
||||
}
|
||||
```
|
||||

|
||||
## 🔧 核心组件详解
|
||||
|
||||
### 1️⃣ DatabaseService (数据库服务层)
|
||||
|
||||
**📖 文件位置：** `lib/services/database_service.dart`
|
||||
|
||||
#### 单例模式 (Singleton Pattern)
|
||||
|
||||
```dart
|
||||
class DatabaseService {
|
||||
static DatabaseService? _instance; // 🏠 私有实例变量
|
||||
static DatabaseService get instance => _instance ??= DatabaseService._(); // 🔑 公共访问方法
|
||||
|
||||
DatabaseService._(); // 🔒 私有构造函数
|
||||
}
|
||||
```
|
||||
|
||||
**🎯 为什么用单例？**
|
||||
- **比喻：** 一个城市只有一个图书馆管理系统
|
||||
- **原因：** 避免多个数据库连接导致的数据冲突
|
||||
- **好处：**
|
||||
- 内存中只有一个实例
|
||||
- 全局访问点
|
||||
- 数据一致性
|
||||
|
||||
**💡 语法解释：**
|
||||
- `static DatabaseService? _instance` - 类级别的私有变量
|
||||
- `??=` - 空赋值操作符 (如果为null就赋新值)
|
||||
- `DatabaseService._()` - 私有命名构造函数
|
||||
|
||||
#### Box概念
|
||||
|
||||
```dart
|
||||
late Box<Book> _booksBox; // 📦 书籍存储盒子
|
||||
```
|
||||
|
||||
**📦 Box是什么？**
|
||||
- Box是Hive的存储容器
|
||||
- 就像贴着标签的储物箱
|
||||
- 每个Box只能存储一种类型的数据
|
||||
- `_booksBox`专门存储Book对象
|
||||
|
||||
#### 数据库初始化过程
|
||||
|
||||
```dart
|
||||
Future<void> init() async {
|
||||
try {
|
||||
// 第1步：获取应用存储位置
|
||||
final appDocumentDir = await getApplicationDocumentsDirectory();
|
||||
|
||||
// 第2步：初始化Hive
|
||||
await Hive.initFlutter(appDocumentDir.path);
|
||||
|
||||
// 第3步：注册TypeAdapter
|
||||
Hive.registerAdapter(BookFormatAdapter());
|
||||
Hive.registerAdapter(ReadingStatusAdapter());
|
||||
Hive.registerAdapter(BookAdapter());
|
||||
|
||||
// 第4步：打开Box
|
||||
_booksBox = await Hive.openBox<Book>('books');
|
||||
|
||||
} catch (e) {
|
||||
// 错误处理
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**🚶♂️ 详细步骤解释：**
|
||||
|
||||
1. **获取存储位置：**
|
||||
- Android: `/data/data/com.yourapp/files/`
|
||||
- iOS: `应用沙盒/Documents/`
|
||||
- 这是系统为应用分配的专属存储空间
|
||||
|
||||
2. **初始化Hive：**
|
||||
- 告诉Hive在哪个路径下创建数据库文件
|
||||
- 只需要执行一次
|
||||
|
||||
3. **注册TypeAdapter：**
|
||||
- 注册Book类型的"翻译官"
|
||||
- 让Hive能理解我们的自定义对象
|
||||
|
||||
4. **打开Box：**
|
||||
- 创建或打开名为'books'的存储容器
|
||||
- 准备存储Book对象
|
||||
|
||||
### 2️⃣ BookRepository (数据访问层)
|
||||
|
||||
**📖 文件位置：** `lib/services/book_repository.dart`
|
||||
|
||||
#### Repository模式
|
||||
|
||||
**🏭 工厂比喻：**
|
||||
- **DatabaseService** = 工厂大门（唯一入口）
|
||||
- **BookRepository** = 书籍车间（专门处理书籍）
|
||||
- **Box** = 货架（存储数据的地方）
|
||||
- **Book对象** = 书籍产品
|
||||
|
||||
#### CRUD操作详解
|
||||
|
||||
**📖 C - Create (创建/添加)**
|
||||
```dart
|
||||
Future<void> addBook(Book book) async {
|
||||
try {
|
||||
final booksBox = _databaseService.getBooksBox(); // 📦 获取存储盒子
|
||||
await booksBox.put(book.id, book); // 📝 存储书籍 (ID作为key)
|
||||
print('✅ 书籍添加成功: ${book.title}');
|
||||
} catch (e) {
|
||||
print('❌ 添加书籍失败: $e');
|
||||
rethrow;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**💡 关键概念：**
|
||||
- `book.id` - 唯一标识符，作为存储的key
|
||||
- `book` - 整个Book对象作为value
|
||||
- 如果key已存在，会覆盖更新（保证数据唯一性）
|
||||
|
||||
**📖 R - Read (读取/查询)**
|
||||
```dart
|
||||
// 读取所有书籍
|
||||
Future<List<Book>> getAllBooks() async {
|
||||
try {
|
||||
final booksBox = _databaseService.getBooksBox();
|
||||
return booksBox.values.toList(); // 📋 获取所有值并转换为列表
|
||||
} catch (e) {
|
||||
// 错误处理
|
||||
}
|
||||
}
|
||||
|
||||
// 根据ID读取特定书籍
|
||||
Future<Book?> getBookById(String id) async {
|
||||
try {
|
||||
final booksBox = _databaseService.getBooksBox();
|
||||
return booksBox.get(id); // 🔍 根据key查找value
|
||||
} catch (e) {
|
||||
// 错误处理
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**💡 语法解释：**
|
||||
- `.values` - 获取Box中所有值
|
||||
- `.get(id)` - 根据key获取特定值
|
||||
- `Book?` - 可空类型（可能找不到）
|
||||
|
||||
**📖 U - Update (更新)**
|
||||
```dart
|
||||
Future<void> updateBook(Book book) async {
|
||||
try {
|
||||
final booksBox = _databaseService.getBooksBox();
|
||||
await booksBox.put(book.id, book); // 🔄 覆盖存储同一ID的书籍
|
||||
} catch (e) {
|
||||
// 错误处理
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**💡 更新原理：**
|
||||
- 使用相同的`put(key, value)`方法
|
||||
- 由于key相同，会覆盖原有数据
|
||||
- 达到更新的效果
|
||||
|
||||
**📖 D - Delete (删除)**
|
||||
```dart
|
||||
Future<void> deleteBook(String id) async {
|
||||
try {
|
||||
final booksBox = _databaseService.getBooksBox();
|
||||
await booksBox.delete(id); // 🗑️ 根据ID删除书籍
|
||||
} catch (e) {
|
||||
// 错误处理
|
||||
}
|
||||
}
|
||||
```
|
||||

|
||||
## 🔢 TypeAdapter详解
|
||||
|
||||
### 什么是TypeAdapter？
|
||||
|
||||
**TypeAdapter = 类型转换器 = 翻译官**
|
||||
|
||||
**🤔 为什么需要TypeAdapter？**
|
||||
- Hive只能存储基本数据类型（String、int、double、bool等）
|
||||
- Hive不知道如何存储自定义对象（如Book）
|
||||
- TypeAdapter负责"翻译"工作
|
||||
|
||||
**🔄 工作流程：**
|
||||
```
|
||||
存储时：Book对象 → TypeAdapter → 二进制数据 → 文件
|
||||
读取时：文件 → 二进制数据 → TypeAdapter → Book对象
|
||||
```
|
||||
|
||||
### 自动生成的TypeAdapter
|
||||
|
||||
**📖 文件位置：** `lib/models/book.g.dart` (自动生成)
|
||||
|
||||
#### read方法 (从文件读取)
|
||||
```dart
|
||||
@override
|
||||
Book read(BinaryReader reader) {
|
||||
final numOfFields = reader.readByte(); // 读取字段总数
|
||||
final fields = <int, dynamic>{
|
||||
for (int i = 0; i < numOfFields; i++) reader.readByte(): reader.read(),
|
||||
};
|
||||
return Book(
|
||||
id: fields[0] as String, // 第0个字段 → id
|
||||
title: fields[1] as String, // 第1个字段 → title
|
||||
author: fields[2] as String?, // 第2个字段 → author (可为空)
|
||||
publisher: fields[3] as String?, // 第3个字段 → publisher (可为空)
|
||||
description: fields[4] as String?, // ... 依此类推
|
||||
// ... 其他字段
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
**💡 工作原理：**
|
||||
1. `BinaryReader` 从二进制文件读取数据
|
||||
2. 读取字段总数
|
||||
3. 按顺序读取每个字段
|
||||
4. 转换为对应的Dart类型
|
||||
5. 构造Book对象
|
||||
|
||||
#### write方法 (写入文件)
|
||||
```dart
|
||||
@override
|
||||
void write(BinaryWriter writer, Book obj) {
|
||||
writer
|
||||
..writeByte(14) // 写入字段总数 (14个字段)
|
||||
..writeByte(0)..write(obj.id) // 写入第0个字段：id
|
||||
..writeByte(1)..write(obj.title) // 写入第1个字段：title
|
||||
..writeByte(2)..write(obj.author) // 写入第2个字段：author
|
||||
// ... 写入所有其他字段
|
||||
}
|
||||
```
|
||||
|
||||
**💡 工作原理：**
|
||||
1. `BinaryWriter` 准备写入二进制文件
|
||||
2. 写入字段总数
|
||||
3. 按顺序写入每个字段的值
|
||||
4. 最终存储为二进制格式
|
||||
|
||||
### 枚举TypeAdapter
|
||||
|
||||
**🔄 枚举为什么也需要TypeAdapter？**
|
||||
- 枚举在Dart中也是自定义类型
|
||||
- Hive需要知道如何存储和读取枚举值
|
||||
- 枚举通常转换为整数存储
|
||||
|
||||
**💡 存储方式：**
|
||||
- `BookFormat.epub` → 存储为整数 0
|
||||
- `BookFormat.mobi` → 存储为整数 1
|
||||
- `BookFormat.txt` → 存储为整数 2
|
||||
- 读取时：0 → `BookFormat.epub`
|
||||

## 🧪 测试验证详解
|
||||
|
||||
### 测试代码分析
|
||||
**📖 文件位置：** `lib/main.dart`
|
||||
|
||||
#### 主函数初始化
|
||||
```dart
|
||||
void main() async {
|
||||
WidgetsFlutterBinding.ensureInitialized(); // 🚦 确保Flutter引擎就绪
|
||||
|
||||
await DatabaseService.instance.init(); // 🏗️ 初始化数据库
|
||||
await runBookRepositoryTest(); // 🧪 运行测试
|
||||
|
||||
runApp(const MyApp()); // 🎬 启动UI
|
||||
}
|
||||
```
|
||||
|
||||
**💡 关键概念：**
|
||||
- `async/await` - 异步操作，因为数据库初始化需要时间
|
||||
- `WidgetsFlutterBinding.ensureInitialized()` - 确保Flutter引擎准备就绪
|
||||
|
||||
#### 测试流程详解
|
||||
|
||||
**🧪 完整测试步骤：**
|
||||
|
||||
1. **获取当前数据状态**
|
||||
```dart
|
||||
List<Book> currentBooks = await bookRepository.getAllBooks();
|
||||
print('📚 当前书籍数量: ${currentBooks.length}');
|
||||
```
|
||||
|
||||
2. **创建测试数据**
|
||||
```dart
|
||||
final testBook = Book(
|
||||
id: 'test_book_001', // 🔑 唯一标识符
|
||||
title: 'Flutter开发入门', // 📚 书名
|
||||
format: BookFormat.epub, // 📄 文件格式
|
||||
status: ReadingStatus.pending, // 📖 阅读状态
|
||||
// ... 其他字段
|
||||
);
|
||||
```
|
||||
|
||||
3. **测试添加功能**
|
||||
```dart
|
||||
await bookRepository.addBook(testBook); // ➕ 添加到数据库
|
||||
```
|
||||
|
||||
4. **验证添加结果**
|
||||
```dart
|
||||
List<Book> updatedBooks = await bookRepository.getAllBooks();
|
||||
print('📚 添加后书籍数量: ${updatedBooks.length}'); // 应该是 +1
|
||||
```
|
||||
|
||||
5. **测试查询功能**
|
||||
```dart
|
||||
Book? foundBook = await bookRepository.getBookById(testBook.id);
|
||||
// 验证找到的书籍信息是否正确
|
||||
```
|
||||
|
||||
6. **测试更新功能**
|
||||
```dart
|
||||
final updatedBook = testBook.copyWith(status: ReadingStatus.completed);
|
||||
await bookRepository.updateBook(updatedBook); // ✏️ 更新状态
|
||||
```
|
||||
|
||||
7. **验证更新结果**
|
||||
```dart
|
||||
Book? updatedFoundBook = await bookRepository.getBookById(testBook.id);
|
||||
// 检查状态是否真的变成了completed
|

**📊 测试验证的关键点：**
|
||||
|
||||
| 测试项 | 验证内容 | 预期结果 |
|
||||
|-------|---------|---------|

|
||||
| **查询功能** | 能否正确检索数据 | ✅ 返回正确的Book对象 |
|
||||
| **更新功能** | 数据更新是否生效 | ✅ 更新后的数据正确保存 |
|
||||
| **对象完整性** | 复杂对象是否完整保存 | ✅ 枚举、日期、列表等字段正确 |
|
||||
| **类型安全** | 类型转换是否正确 | ✅ 没有类型转换错误 |

## 🔧 常见问题和解决方案
|
||||
|
||||
### 1️⃣ TypeAdapter错误
|
||||
```
|
||||
HiveError: Cannot write, unknown type: BookFormat. Did you forget to register an adapter?
|
||||
```
|
||||
|
||||
**🔧 解决方案：**
|
||||
```dart
|
||||
// 在DatabaseService.init()中注册所有TypeAdapter
|
||||
Hive.registerAdapter(BookFormatAdapter());
|
||||
Hive.registerAdapter(ReadingStatusAdapter());
|
||||
Hive.registerAdapter(BookAdapter());
|
||||
```
|
||||
|
||||
**💡 错误原因：**
|
||||
- Hive不知道如何序列化自定义类型
|
||||
- 需要先注册TypeAdapter再使用该类型
|
||||
|
||||
### 2️⃣ Box未打开错误
|
||||
```
|
||||
Exception: Book Box未打开，请先调用init()
|
||||
```
|
||||
|
||||
**🔧 解决方案：**
|
||||
- 确保先调用 `DatabaseService.instance.init()`
|
||||
- 不要在init()完成前访问Box
|
||||
- 检查初始化顺序是否正确
|
||||
|
||||
### 3️⃣ 应用启动顺序
|
||||
```dart
|
||||
void main() async {
|
||||
// 正确的初始化顺序
|
||||
WidgetsFlutterBinding.ensureInitialized(); // 1. Flutter引擎
|
||||
await DatabaseService.instance.init(); // 2. 数据库
|
||||
runApp(const MyApp()); // 3. UI
|
||||
}
|
||||
```
|
||||
|
||||
### 4️⃣ TypeAdapter重新生成
|
||||
```bash
|
||||
# 清理并重新生成
|
||||
dart run build_runner clean
|
||||
dart run build_runner build --delete-conflicting-outputs
|
||||
```
|
||||
|
||||
**🔄 何时需要重新生成：**
|
||||
- 修改了数据模型（添加/删除字段）
|
||||
- 更改了Hive注解
|
||||
- 修改了枚举定义
|
||||

||||
status: ReadingStatus.pending,
|
||||
addedDate: DateTime.now(),
|
||||
);
|
||||
await bookRepository.addBook(book);
|
||||
|
||||
// 2. 用户开始阅读
|
||||
final updatedBook = book.copyWith(
|
||||
status: ReadingStatus.reading,

||||
lastReadDate: DateTime.now(),
|
||||
);
|
||||
await bookRepository.updateBook(updatedBook);
|
||||
|
||||
// 3. 用户添加书签
|
||||
final bookmark = Bookmark(
|
||||
bookId: book.id,

|
||||
await bookmarkRepository.addBookmark(bookmark);
|
||||
```

## 🚀 性能优化建议
|
||||
|
||||
### 1️⃣ 异步操作优化
|
||||
|
||||
```dart
|
||||
// ❌ 不要这样写（阻塞UI）
|
||||
List<Book> books = bookRepository.getAllBooks(); // 同步操作
|
||||
|
||||
// ✅ 应该这样写（不阻塞UI）
|
||||
List<Book> books = await bookRepository.getAllBooks(); // 异步操作
|
||||
```
|
||||
|
||||
### 2️⃣ 错误处理最佳实践
|
||||
|
||||
```dart
|
||||
try {
|
||||
await bookRepository.addBook(book);
|
||||
} on HiveException catch (e) {
|
||||
// 处理Hive特定错误
|
||||
print('数据库错误: ${e.message}');
|
||||
} catch (e) {
|
||||
// 处理其他错误
|
||||
print('未知错误: $e');
|
||||
}
|
||||
```
|
||||
|
||||
### 3️⃣ 内存管理
|
||||
|
||||
```dart
|
||||
// 🔄 及时关闭数据库连接
|
||||
@override
|
||||
void dispose() {
|
||||
DatabaseService.instance.close();
|
||||
super.dispose();
|
||||
}
|
||||
```
