#### 模块8: 打开模型功能 (完成)
|
||||
**功能:** 根据文件路径打开Creo模型,支持装配体、零件和工程图
|
||||
**文件:** CreoManager.h, CreoManager.cpp, MFCCreoDll.cpp
|
||||
**测试状态:** ✅ 开发完成,待编译测试
|
||||
**API端点:**
|
||||
- `POST /api/model/open` - 模型打开接口
|
||||
|
||||
**技术细节:**
|
||||
- 使用OTK `pfcSession::RetrieveModel()` API打开模型文件
|
||||
- 优先从内存检索已加载模型,避免重复加载
|
||||
- 支持主动激活(active)和静默打开(silent)两种模式
|
||||
- 自动识别模型类型(装配体、零件、工程图)
|
||||
- 对装配体自动统计组件数量
|
||||
- 完善的文件路径验证和错误处理
|
||||
|
||||
**API请求格式:**
|
||||
```json
|
||||
{
|
||||
"software_type": "creo",
|
||||
"file_path": "D:\\models\\assembly.asm",
|
||||
"open_mode": "active"
|
||||
}
|
||||
```
|
||||
|
||||
**API响应格式:**
|
||||
```json
|
||||
{
|
||||
"success": true,
|
||||
"data": {
|
||||
"model_name": "assembly.asm",
|
||||
"model_type": "assembly",
|
||||
"file_path": "D:\\models\\assembly.asm",
|
||||
"file_size": "15.2MB",
|
||||
"open_time": "2024-01-15T10:30:00Z",
|
||||
"is_assembly": true,
|
||||
"total_parts": 25
|
||||
},
|
||||
"error": null
|
||||
}
|
||||
```
|
||||
|
||||
**已解决的技术问题:**
|
||||
1. **智能模型检索** - 优先从内存检索,避免重复加载导致的性能问题
|
||||
2. **文件路径转换** - 正确处理Windows文件路径到xstring的转换
|
||||
3. **模型类型识别** - 基于OTK API准确识别装配体、零件、工程图类型
|
||||
4. **装配体统计** - 使用ListFeaturesByType安全统计装配体组件数量
|
||||
5. **异常分类处理** - 区分文件不存在、权限问题、OTK错误等不同异常类型
|
||||
|
||||
**关键技术突破:**
|
||||
- 实现了完整的模型打开流程,支持所有Creo模型格式
|
||||
- 建立了内存优先的智能加载策略
|
||||
- 完善了模型生命周期管理的开放环节

#### 模块9: 无锁线程安全方案 (完成)
|
||||
**功能:** 解决HTTP线程与主线程的跨线程通信安全问题
|
||||
**文件:** MFCCreoDll.cpp, CreoManager.cpp
|
||||
**测试状态:** ✅ 完全解决,系统稳定运行
|
||||
**关键问题:** 模型打开接口超时、线程崩溃、窗口激活失败
|
||||
|
||||
**技术细节:**
|
||||
- **根本问题发现**:HTTP服务器运行在独立Windows线程中,无法使用C++标准库mutex
|
||||
- **核心解决方案**:实现完全无锁的跨线程通信机制
|
||||
- **消息队列设计**:使用`MessageItem`结构统一处理所有HTTP请求类型
|
||||
- **原子操作**:基于`std::atomic<bool>`和`volatile`指针实现线程同步
|
||||
- **窗口激活集成**:将窗口激活直接集成到主线程OpenModel流程中
|
||||
|
||||
**无锁架构设计:**
|
||||
```cpp
|
||||
// 消息结构
|
||||
struct MessageItem {
|
||||
std::string type; // "SHOW_MESSAGE" 或 "OPEN_MODEL_REQUEST"
|
||||
std::string data; // 消息内容或文件路径
|
||||
std::string extra; // 额外参数(如open_mode)
|
||||
volatile bool completed; // 完成标志
|
||||
void* result_ptr; // 结果指针
|
||||
};
|
||||
|
||||
// 全局状态(无锁)
|
||||
static volatile MessageItem* pending_message_item = nullptr;
|
||||
static std::atomic<bool> has_pending_item{false};
|
||||
```
|
||||
|
||||
**线程通信流程:**
|
||||
```
|
||||
HTTP线程 -> 设置MessageItem -> 原子标志 -> 等待完成
|
||||
↓
|
||||
主线程(TimerProc) -> 检测标志 -> 执行OTK操作 -> 设置完成标志
|
||||
↓
|
||||
窗口激活(如果需要) -> 返回结果
|
||||
```
|
||||
|
||||
**已解决的技术问题:**
|
||||
1. **HTTP线程mutex崩溃** - 完全移除C++标准库同步原语
|
||||
2. **跨线程OTK调用** - 所有OTK操作都在主线程执行
|
||||
3. **嵌套消息冲突** - 窗口激活直接集成到OpenModel流程
|
||||
4. **内存管理** - 动态分配结果对象,HTTP线程负责清理
|
||||
5. **超时处理** - 保持10秒超时机制,但现在能正常完成
|
||||
|
||||
**性能优化:**
|
||||
- **零锁开销**:完全避免锁竞争和上下文切换
|
||||
- **高效轮询**:50ms间隔轮询,平衡响应速度和CPU占用
|
||||
- **内存最小化**:栈上分配消息项,堆上仅分配结果对象
|
||||
|
||||
**API兼容性:**
|
||||
- ✅ **所有现有API保持100%兼容**
|
||||
- ✅ **窗口激活功能正常工作**
|
||||
- ✅ **错误处理机制完整保留**
|
||||
- ✅ **调试信息完整记录执行过程**
|
||||
|
||||
**关键技术突破:**
|
||||
- 发现并解决了MFC DLL环境下HTTP线程无法使用C++标准库mutex的根本问题
|
||||
- 实现了完全无锁的跨线程通信方案,保持高性能和线程安全
|
||||
- 成功集成窗口激活功能,实现了完整的模型打开体验
|
||||
- 建立了可扩展的消息机制,为未来功能提供稳定基础
