完成从Node.js/NestJS到Java Spring Boot的后端迁移，修复资源管理API错误。

**核心修复：**
- 修复资源库API 500错误 - ResourceLibrary/ResourceItem实体与数据库表结构对齐
- 更新ID类型从Long改为String，匹配数据库varchar(32)
- 修正字段映射（libraryType → type）

**新增Java实体（7个）：**
- CoursePackage, CoursePackageCourse, TenantPackage
- CourseLesson, LessonStep, LessonStepResource
- Theme

**新增API控制器（5个）：**
- AdminResourceController - 资源库管理
- AdminPackageController - 课程套餐管理
- AdminCourseLessonController - 课程环节管理
- AdminThemeController - 主题字典管理
- SchoolPackageController - 学校套餐管理

**新增服务层（5个）：**
- ResourceLibraryService, CoursePackageService, CourseLessonService
- ThemeService, FileStorageService

**文档更新：**
- 新增 Java环境配置与启动指南.md
- 新增 Java后端启动完整指南.md
- 新增 数据库迁移指南.md
- 更新 CHANGELOG.md 和开发日志

**前端修复：**
- 解决package.json合并冲突

+
+## 技术栈决策
+
+### 后端技术栈（必须遵守）
+
+⚠️ **严禁使用 Node.js/NestJS 进行后端开发**

+| 框架 | **Spring Boot** | 3.2+ | 基于 Java 17 |
+| 持久层 | **MyBatis-Plus** | 3.5+ | 简化 CRUD |
+| 数据库连接池 | **Alibaba Druid** | 1.2+ | 数据库连接池 + 监控 |
+| 安全 | **Spring Security + JWT** | - | 无状态认证 + RBAC |
+| API 文档 | **Knife4j (SpringDoc)** | 4.x | OpenAPI 3.0 |
+| 数据库 | **MySQL** | 8.0+ | 关系型数据库 |
+| 迁移 | **Flyway** | - | 版本化数据库变更 |
+| 校验 | **Hibernate Validator** | - | JSR-303 参数校验 |
+| 缓存 | **Redis + Spring Data Redis** | - | 缓存、会话存储 |

+
+### 前端技术栈
+
+| 组件 | 技术选型 | 版本 | 说明 |
+|------|---------|------|------|
+| 框架 | **Vue 3** | 3.4+ | Composition API |
+| 语言 | **TypeScript** | 5.x | 严格模式 |

+## 后端开发规范
+
+### 三层架构规范
+
+**核心原则：Service 层和 Mapper 层必须使用实体类（Entity）接收和返回数据，严禁在 Service 层和 Mapper 层之间使用 DTO/VO 转换。**
+
+| 层级 | 职责 | 数据类型 |
+|------|------|----------|
+| **Controller** | 接收请求、参数校验、返回响应 | DTO ↔ Entity/VO |
+| **Service** | 业务逻辑、事务控制 | Entity |
+| **Mapper** | 数据库操作 | Entity |
+
+### Controller 层规范
+
+```java
+@RestController
+@RequestMapping("/api/v1/xxx")
+@Tag(name = "XXX管理", description = "XXX相关接口")
+@RequiredArgsConstructor
+public class XxxController {
+    
+    private final XxxService xxxService;
+    
+    @GetMapping
+    @Operation(summary = "查询列表")
+    public Result<PageResult<XxxVO>> list(PageQueryDto dto) {
+        PageResult<Xxx> pageResult = xxxService.page(dto);
+        return Result.success(convertToVO(pageResult));
+    }
+}
+```
+
+### Service 层规范
+
+```java
+public interface XxxService extends IService<Xxx> {
+    PageResult<Xxx> page(PageQueryDto dto);
+}
+
+@Service
+@RequiredArgsConstructor
+public class XxxServiceImpl extends ServiceImpl<XxxMapper, Xxx> 
+    implements XxxService {
+    
+    @Override
+    public PageResult<Xxx> page(PageQueryDto dto) {
+        // 只使用 Entity，不使用 DTO
+        Page<Xxx> page = this.lambdaQuery()
+            .eq(Xxx::getStatus, 1)
+            .page(new Page<>(dto.getPage(), dto.getPageSize()));
+        return PageUtils.of(page);
+    }
+}
+```
+
+### Mapper 层规范
+
+```java
+@Mapper
+public interface XxxMapper extends BaseMapper<Xxx> {
+    // 继承 BaseMapper，使用 MyBatis-Plus 内置方法
+}
+```
+
+---
+
+## 前端开发规范
+
+### API 开发规范（Orval）
+
+1. **生成代码只读** - 不得在 `src/api/generated/` 内做任何手工修改
+2. **以生成类型为准** - 参数/返回类型优先使用生成的类型
+3. **统一调用入口** - 通过 `src/api/client.ts` 访问
+
+### 推荐调用方式
+
+```typescript
+import { readingApi } from '@/api/client';
+
+async function loadTenant(id: number) {
+  const res = await readingApi.getTenant({ id });
+  return res.data;
+}
+```
+
+### Vue SFC 约定
+
+- 优先使用 `<script lang="ts" setup>`
+- 页面样式使用 `scoped`
+- 允许使用 UnoCSS 原子类
+
+### 路由规范
+
+```typescript
+import { definePage } from 'vue-router/auto';
+
+definePage({
+  alias: ['/xxx', '/yyy'],
+});
+```

+# Java 后端启动指南
+
+## 问题：本地缺少 Maven 构建工具
+
+启动 Spring Boot 项目需要 Maven 或 Gradle。
+
+---
+
+## 方式 1：安装 Maven（推荐）
+
+### macOS 使用 Homebrew 安装：
+
+```bash
+# 1. 安装 Homebrew（如果没有）
+/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
+
+# 2. 安装 Maven
+brew install maven
+
+# 3. 验证安装
+mvn -version
+
+# 4. 启动后端
+cd /Users/retirado/Program/ccProgram_0312/reading-platform-java
+mvn spring-boot:run
+```
+
+---
+
+## 方式 2：使用 IntelliJ IDEA（最简单）
+
+1. 打开 IntelliJ IDEA
+2. 选择 `File` → `Open`
+3. 选择目录：`/Users/retirado/Program/ccProgram_0312/reading-platform-java`
+4. 等待 Maven 依赖下载完成
+5. 找到 `ReadingPlatformApplication.java` 主类
+6. 右键 → `Run 'ReadingPlatformApplication'`
+
+---
+
+## 方式 3：使用 VS Code
+
+1. 安装 `Spring Boot Extension Pack` 插件
+2. 打开 Java 项目目录
+3. 点击侧边栏的 `SPRING BOOT DASHBOARD`
+4. 点击启动按钮
+
+---
+
+## 方式 4：下载 Maven 手动安装
+
+如果无法使用 Homebrew，可以手动下载 Maven：
+
+```bash
+# 下载 Maven
+wget https://downloads.apache.org/maven/maven-3/3.9.6/binaries/apache-maven-3.9.6-bin.tar.gz
+
+# 解压
+tar -xzf apache-maven-3.9.6-bin.tar.gz
+
+# 设置环境变量
+export PATH=$PATH:/path/to/apache-maven-3.9.6/bin
+
+# 验证
+mvn -version
+```
+
+---
+
+## 启动成功后
+
+访问以下地址验证服务：
+
+- **API 文档**: http://localhost:8080/swagger-ui.html
+- **健康检查**: http://localhost:8080/actuator/health
+
+---
+
+## 日志输出位置
+
+启动后，后端日志将显示在控制台。
+
+---
+
+## 问题排查
+
+如果启动失败，检查：
+1. **数据库连接** - 确认能连接到 8.148.151.56:3306
+2. **端口占用** - 确保 8080 端口没有被占用
+3. **JDK 版本** - 需要 JDK 17 或更高版本
+
+检查 JDK：
+```bash
+java -version
+```
+
+---
+
+**推荐**: 使用 IntelliJ IDEA 是最简单的方式，会自动下载所有依赖并启动项目。

+
+### 3. 测试登录接口
+
+**请求示例：**
+```bash
+curl -X POST http://localhost:8080/api/auth/login \
+  -H "Content-Type: application/json" \
+  -d '{"username":"admin","password":"admin123"}'
+```
+
+**预期响应：**
+```json
+{
+  "code": 200,
+  "message": "success",
+  "data": {
+    "token": "eyJhbGc...",
+    "userId": 1,
+    "username": "admin",
+    "name": "平台管理员",
+    "role": "admin"
+  }
+}
+```
+
+### 4. 测试新 API 端点
+
+使用返回的 token 测试受保护的接口：
+
+```bash
+TOKEN="返回的token值"
+
+# 查询主题列表
+curl http://localhost:8080/api/v1/admin/themes \
+  -H "Authorization: Bearer $TOKEN"
+
+# 查询课程套餐
+curl http://localhost:8080/api/v1/admin/packages \
+  -H "Authorization: Bearer $TOKEN"
+
+# 查询资源库
+curl http://localhost:8080/api/v1/admin/resources/libraries \
+  -H "Authorization: Bearer $TOKEN"
+```
+
+---
+
+## 数据库配置

 # 开发日志 - 2026-03-12
 
+## 今日任务：代码重构（规范化）→ Java 后端迁移
+
+根据用户决策，不再使用 Node.js 后端，全面迁移到 Java (Spring Boot)。
+
+---
+
+## 上午工作：Java 后端环境配置与启动 ✅
+
+### 环境安装
+
+**使用 SDKMAN 安装（无需 sudo）：**

+
+**Mapper 接口（7个）：**
+- `CoursePackageMapper`
+- `CoursePackageCourseMapper`
+- `TenantPackageMapper`
+- `CourseLessonMapper`
+- `LessonStepMapper`
+- `LessonStepResourceMapper`
+- `ThemeMapper`
+
+**Service 类（5个）：**
+- `ThemeService` - 主题 CRUD 操作
+- `CoursePackageService` - 套餐生命周期管理
+- `CourseLessonService` - 课程环节和教学步骤管理
+- `FileStorageService` - 文件上传下载
+- `ResourceLibraryService` - 资源库和项目管理
+
+**Controller 类（6个）：**
+- `AdminThemeController` - `/api/v1/admin/themes` 端点

+- `SchoolPackageController` - `/api/v1/school/packages` 端点
+- `AdminCourseLessonController` - `/api/v1/admin/courses/{courseId}/lessons` 端点
+- `AdminResourceController` - `/api/v1/admin/resources` 端点
+- `FileUploadController` - `/api/v1/files/upload` 端点
+
+### 配置更新
+
+**application.yml 配置：**
+```yaml
+spring:
+  datasource:
+    url: jdbc:mysql://8.148.151.56:3306/reading_platform
+    username: root
+    password: reading_platform_pwd
+
+jwt:
+  secret: readingPlatformJwtSecretKeyForTokenGeneration2024
+  expiration: 86400000  # 24小时
+```
+
+### 修复的问题
+
+1. ✅ 添加 Spring Boot AOP 依赖（AspectJ）
+2. ✅ 修复 @RequireRole 注解类型不匹配

+
+---
+
+## 下午工作：API 测试与问题修复 ✅
+
+### 登录测试成功
+
+```bash
+curl -X POST http://localhost:8080/api/auth/login \
+  -H "Content-Type: application/json" \
+  -d '{"username":"admin","password":"admin123"}'
+```
+
+**返回结果：**
+```json
+{
+  "code": 200,
+  "message": "success",
+  "data": {
+    "token": "eyJhbGc...",
+    "userId": 1,
+    "username": "admin",
+    "name": "平台管理员",
+    "role": "admin"
+  }
+}
+```
+
+### API 端点测试结果
+
+| 端点 | 状态 | 说明 |
+|------|------|------|
+| POST /api/auth/login | ✅ | JWT Token 生成正常 |
+| GET /api/v1/admin/themes | ✅ | 返回空数组（正常） |
+| GET /api/v1/admin/packages | ✅ | 返回分页数据 |
+| POST /api/v1/admin/themes | ✅ | 成功创建主题 |
+| GET /api/v1/admin/resources/libraries | ✅ | 修复后正常 |
+| POST /api/v1/admin/resources/libraries | ✅ | 成功创建资源库 |
+
+### 资源库问题修复
+
+**问题：** 资源库接口返回 500 错误
+
+**原因：**
+- 数据库表名为 `t_resource_library`（`t_` 前缀）
+- 实体类使用了错误的表名 `resource_libraries`
+- 实体字段与数据库不匹配（`type` vs `libraryType`）
+- ID 类型不匹配（数据库 varchar(32) vs 实体 Long）
+
+**修复：**
+1. 更新 `@TableName` 为 `t_resource_library`
+2. 更新字段名匹配数据库结构
+3. 更新 ID 类型为 String
+4. 重写 ResourceLibraryService 和 AdminResourceController
+
+### 最终测试结果
+
+**服务状态：**
+- ✅ Java 17.0.18 运行正常
+- ✅ Maven 3.9.13 构建正常
+- ✅ Spring Boot 3.2.3 启动正常
+- ✅ 服务端口 8080 监听正常

+  PRIMARY KEY (`id`),
+  KEY `idx_step_id` (`step_id`)
+) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COMMENT='环节资源关联表';
+```
+
+### 7. 主题字典表
+
+```sql
+CREATE TABLE IF NOT EXISTS `theme` (
+  `id` BIGINT NOT NULL AUTO_INCREMENT,
+  `name` VARCHAR(255) NOT NULL COMMENT '主题名称',
+  `description` TEXT COMMENT '主题描述',
+  `sort_order` INT NOT NULL DEFAULT 0 COMMENT '排序号',
+  `status` VARCHAR(50) NOT NULL DEFAULT 'ACTIVE' COMMENT '状态',
+  `created_at` DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP,
+  `updated_at` DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
+  PRIMARY KEY (`id`),
+  KEY `idx_status` (`status`)
+) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COMMENT='主题字典表';
+```
+
+---
+
+## 验证表创建
+
+执行完成后，运行以下 SQL 验证：
+
+```sql
+-- 查看所有表
+SHOW TABLES;
+
+-- 查看新创建的表
+SELECT TABLE_NAME, TABLE_COMMENT
+FROM information_schema.TABLES
+WHERE TABLE_SCHEMA = 'reading_platform'
+AND TABLE_NAME IN ('course_package', 'course_package_course', 'tenant_package',
+                   'course_lesson', 'lesson_step', 'lesson_step_resource', 'theme');
+```
+
+---
+
+## 注意事项
+
+1. **执行前备份**: 建议先备份数据库
+2. **字符集**: 所有表使用 utf8mb4 字符集
+3. **引擎**: 使用 InnoDB 存储引擎
+4. **索引**: 已创建必要的索引以提高查询性能
+
+---
+
+## 下一步
+
+表创建完成后，可以：
+1. 启动 Java 后端应用
+2. 访问 Swagger 文档测试 API：`http://localhost:8080/swagger-ui.html`
+3. 进行功能测试
